Summary report on technical work of electronic specialty

The summary of electronic professional technical work is to let electronic personnel do their jobs with modest attitude and full enthusiasm. I want to share with you the summary report of electronic professional and technical work. Welcome to browse.

The first article: Summary report on technical work of electronic specialty. I entered xx on X, as an electrical instrument technician. As a person with only petrochemical work experience and no paper mill work experience, I am a little confused about the company's work flow, but the company's harmonious working atmosphere, United and pragmatic culture, rigorous and safe work flow, especially the concern of the company's leaders and the enthusiastic help of colleagues, made me quickly complete the change of my work role. In the past two months, I have been strict with myself, earnestly and timely doing every task assigned by the leaders, learning from my colleagues with an open mind about problems that I don't understand professionally and non-professionally, constantly improving and enriching myself, hoping to become independent as soon as possible and make greater contributions to the company.

When I came to work in China Tobacco Company, my biggest gain was the company's corporate culture safety, 5s, a little course and reasonable suggestions! Let's summarize the corporate culture of the company: 1) Among them, safety is one of the most important things, and safety is always the first in any work process. No matter what kind of maintenance work is carried out, maintenance equipment and energy should not only be locked to ensure personal and equipment safety, but also adequate safety measures must be taken to ensure foolproof before the work can be carried out, which is enough to prove how much the company attaches importance to the safety of any employee! 2) Benefits of 2)5s management: It can prove the daily quality of employees. 5s management is of great help to our work. For example, we need spare parts in the process of repairing equipment, and we can find spare parts as soon as we get to the spare parts room, because we insist on doing 5S in the spare parts room every day! 3) A little course: Everyone can share their unique and learned professional or non-professional knowledge with colleagues, which can increase their understanding of professional or non-professional knowledge! 4) Rationalization suggestion: It can help the company to put forward some rationalization suggestions and transform the suggestions on equipment, safety, technology and production, which can be of great help to some technologies, equipment or safety of the company.

During the trial period, every time I stopped for maintenance, the intense and rigorous maintenance made me feel that as an electrical instrument technician, I had a great responsibility in this position. Especially when working in a paper machine, we must pay great attention to personal and equipment safety. In the process of maintenance, no small parts can fall into the transmission parts, otherwise the whole network and other transmission parts will be scrapped, and I should also pay attention to my mechanical damage. I should take security measures to protect myself. Therefore, I think working in China Tobacco requires not only excellent professional and technical level, but also a strong sense of responsibility. Carefully check the hidden dangers of equipment every day, and do not let the equipment run with faults to ensure the smooth production of the company.

Here, I have made great progress and improvement in professionalism, thinking, safety and working ability, which inspires me to keep advancing and perfecting in my work. I hope to continue to exercise myself and realize my ideal opportunity on the day of smoking Modi. I will do my job with humility and full enthusiasm, create value for China Tobacco and look forward to a bright future!

Part II: Summary report on technical work of electronic specialty. Time flies, and I have graduated for three years in a blink of an eye. I have worked in xx Company for more than two years. Due to the need of work and improving my technical level, I entered the technical department of xx Power Distribution Equipment Co., Ltd. to study and work. I have worked in xx Company for more than two years and have grown into a qualified electrical engineer.

First, the growth process.

When I first entered the company, I had to practice in the electrical workshop. During the period, I was mainly familiar with the products, laying the foundation for future design. After the internship, I officially entered the technical department.

At first, I was mainly responsible for designing some small orders, such as small boxes, pgl, ggd, and some relatively standard xgn36( 15)- 12. Usually a few, or orders with an output value of no more than 65438+ million. During this time, I studied with the chief engineer and the old engineer, trained professional skills and basic knowledge at night, and then checked the learning results on the order. I was deeply impressed and influenced by my study and work during this period.

Some standard engineering instructions, such as star delta step-down start, full pressure start, autotransformer step-down start, motor forward and backward rotation, etc. I learned them all at school, but I was not impressed at that time. After doing these motor control projects, the previous theory and practice are combined to design a control product with its own style. Such as temperature control box, gas control box, street lamp control box, etc. The main problem encountered by this kind of products is the arrangement of components, which directly affects the overall size of boxes or cabinets and the direction of cables. Once you are not careful, users will encounter many problems during installation and use. When making this kind of products, we must be careful, go to the site to communicate with customers, and after understanding customers' intentions, it is best to design the general plan and outline map for customers to confirm.

With the growth of experience, we began to make a relatively large set of gck, usually dozens or hundreds, and the output value usually exceeds 500,000 yuan or even one million yuan. The main functional units are: metering cabinet, incoming cabinet, capacitance compensation cabinet, feeding cabinet, municipal power generation conversion cabinet and contact cabinet. Basically, every two years, Dongguan Power Supply Bureau of Guangdong Power Grid will put forward new requirements for metering cabinets. Usually, within one month of putting forward new requirements, there are the most problems. For example, the former transformers of 3 15kva and above are required to be equipped with two sets of current transformers, one active meter and one electronic meter, and charged with low voltage. At present, a group of current transformers and an active meter must be equipped with a 10kv high-voltage metering cabinet, and the high-voltage charging method is adopted. If we don't pay attention to this problem, the goods will not be connected to the site and will not pass the acceptance. The amount of on-site decoration works is very large, which will bring negative influence to the company.

The feeding unit commonly used in gck is drawer cabinet, which is a relatively advanced cabinet type in China. What you usually need to pay attention to is whether there is a load. Non-fire demand load? This load must be cut off in case of fire to prevent the accident from expanding. A dc24v fire-fighting shunt coil is usually added to the molded case circuit breaker to realize tripping. Many people understand it as? No? What load must have fire protection? Results The tripping coil was added in the wrong position, and some fire fighting loads such as fire fighting fan and fire fighting pump jumped off. In fact, the fire load cannot be cut off. Once a fire breaks out, it will lead to a more serious fire. It should be understood as? Non-fire load that must be protected? .

After that, we began to make the high-voltage cable distribution box dfw- 12, the high-voltage and low-voltage pre-installed power station ybp(m), and then to XCN15 ring network cabinet, kyn28a- 12 central cabinet, as well as more complicated plc and frequency conversion control cabinet, DC screen (gzdw) and signal screen. From simple to complex; From small projects and small batches to large projects and multiple large orders; With the increase of design projects and experience, I can skillfully and reasonably master the design of system schematic diagram and secondary control wiring diagram of various cabinets, including various non-standard motors, fans, fire control boxes, and various dual power supply and multi-power supply three-in-one and five-in-one systems. At the same time, I am very familiar with the structural characteristics of various cabinets. Responsible for the design of Dongguan Baishiwei Real Estate (Yongya Villa), Dongguan Party School, Chang 'an South China Electronics Factory, City College of Dongguan University of Technology, Akzo Nobel Coatings (Dongguan) Co., Ltd., electrical room of Dongguan Guofeng Grain and Oil Center, office building of Dongguan Ecological Park, residential area of Chashan Meiliwan Garden, Dongguan University of Technology, etc. Through the cooperation with Party A and weak current designers, we have a more comprehensive understanding of the design and operation of power system. In recent years, I followed the chief engineer to participate in the analysis of vertical bus terminal arc accident in Zhujiang Brewery, the short-circuit fault analysis of Fenggang Power Supply Company 10kv outdoor cable distribution box, the treatment scheme of nave Sha Pump Factory affected by harmonics, and the noise treatment of large current cabinet in Dongguan Yuyuan Shoes Factory, which deepened my understanding of theoretical knowledge, better combined theory with practice, deepened my impression, updated my understanding of products and broadened my horizons.

Keep pace with the times and keep innovating, so does the power industry. In order to meet the demand of power grid, Dongguan Power Supply Bureau requires customers to adopt user-defined circuit breaker cabinets with quick protection function for single power supply incoming lines of 65438+20XKV non-dedicated lines, so as to avoid distribution network failures caused by customers' electrical equipment failures, reduce losses caused by fault current and greatly improve power supply reliability. For example, when the T-branch line of 10kv overhead distribution line or the end user fails internally, the outgoing switch of the substation will trip because the time limit of incoming switch protection cannot be properly adjusted with that of outgoing switch protection of the substation. If the fault is permanent, the substation reclosing will not succeed, and the local accident within the boundary of medium voltage users will make the whole 10kv distribution line cut off, with disastrous consequences. If the user boundary switch (commonly known as watchdog) is installed at the T-junction or user terminal (responsibility demarcation point), as well as faults (such as overcurrent, short circuit, single-phase grounding, etc. ) and automatically isolate faults, which can ensure the normal power consumption of users in non-fault areas.

Second, new product development and process improvement.

In recent years, due to the slow economic growth, the market demand for distribution products has plummeted, and the competition among distribution equipment manufacturers has become increasingly fierce; During this period, the company strictly grasps the product quality, optimizes the design scheme and reduces the cost on the premise of ensuring the quality.

1. Through the improvement of the drawer secondary plug-in, the phenomenon of cracking and wrong insertion of the secondary plug-in is greatly reduced, and the reliability of electricity consumption is ensured;

2. Put forward requirements for the primary and secondary processes of products, such as unified line number, unified pipe length and unified installation method. , so as to make the wiring of products beautiful and reasonable, ensure the consistency of products, and improve some unreasonable places;

3. The original capacitor cabinet used two discharge lamps in each loop. Since the capacitor now has a discharge resistance, one lamp is used in each loop, thus saving the cost. The manufacturing cost is reduced, the working efficiency is improved, and the waste phenomenon is eliminated.

4. In terms of new products, under the guidance of the general manager and the leadership of the company's senior engineers, the company successfully developed two new products: 10kv vs 1 high voltage vacuum circuit breaker and high voltage sf6 SF6 SF6 load switch, which enhanced the company's competitiveness. At the same time, through the design and improvement of the secondary circuit of the circuit breaker and the design of the inspection cabinet for testing the secondary circuit of the circuit breaker, we have a deeper understanding of the switch itself.

5. In XX, under the leadership of general manager Li, a 4000a high-voltage and high-current cabinet was successfully developed, which filled the blank of no production in Dongguan.

6. The company only does not do it.

Only innovation can achieve sustainable development. This year, under the leadership of general manager Zhang, Zhang, Wang Gong, the company independently innovated and successfully developed xfw 1 frame circuit breaker and xfm 1 molded case circuit breaker. At present, these two products are in the experimental stage. I believe that in the near future, Xiong Feng brand will occupy a certain market in the field of switches in China.

Third, the standardization of working procedures.

Standardization of working procedures can reduce the chance of human error and ensure the accuracy of drawings. As the core department of the company and the designer as the project leader, the technical department assists the sales department to make the electrical schematic diagram and cabinet panel layout for customers, which improves the accuracy of quotation, avoids inconsistency with customer requirements and reduces the error rate; For the production department, strive to make all designers' painting styles and design ideas unified and standardized; At the same time, after the drawings were issued, technicians tracked and communicated with workers all the way from sheet metal, welding, powder spraying and assembly to secondary wiring of complete electrical installation, and listened to their valuable opinions to make the products more perfect.

? It's a long way to go, Xiu Yuan, Xiu Yuan. I'll go up and down, okay? With the care of company leaders and the support and help of colleagues, through unremitting efforts, I have acquired certain technical working ability and can basically work independently, but there are still some shortcomings. In the future work, I will continue to recharge my batteries and learn from experienced colleagues, peers and workshop operators the skills or skills that I don't really have, and apply what I have learned. Through study and practice, I exercise and grow in practical work, accumulate work experience, strive to improve my own quality and professional and technical level, and deliver positive energy for the company's development and growth.

Chapter III: Summary Report on Technical Work of Electronic Specialty. I am an electronic technical engineer. I joined the company in February of xx, and it has been more than 1 year now. During this period (including now), I have been staying in a company. Recently, my mood has fluctuated greatly, and I feel a little confused when I make a choice about my future career development direction. There are both subjective and objective factors, and I haven't thought it through. Now, I want to list more than one year's work experience, so as to sum up the past and better understand myself.

Because I was an intern in this company before, I volunteered to stay when I graduated. Responsible for the development of multiple products in a project after joining the company. At the beginning, I didn't know enough about this project, and I didn't analyze what work was needed to develop the whole system. Later, I found that there were too many things to develop, but I survived step by step.

Now that this product has seen its prototype and is being put on the market, I can't say I'm happy. The most important thing is that I don't trust the product, and I am worried that there will be many problems in the application, which will bring great inconvenience to customers.

The manager of my department told me that the first few years of work have a great influence on my future career development, especially in the first one or two years, I will gradually form my work attitude, work characteristics and behavior habits. Once these habits are formed, they are hard to change, so I must not form bad work habits and attitudes. Fortunately, I persisted for a year, but I have been a little slack recently. Maybe things are less, and people are getting a little lazy.

In more than a year, I gradually developed from a student to a junior engineer (self-styled), during which I also learned a lot of knowledge and skills. The project I am responsible for is also an embedded application system, which involves software and hardware design, but does not use the operating system. At first, the department manager participated and worked with me for a while. Later, I was in charge of this project. From system function design, hardware design, board making, software programming (C language), component procurement, functional module debugging, system debugging, to discussing structural design with structural engineers, outsourcing technical cooperation processing, and then visiting customers and understanding specific market demand, I deeply realized that product design needs patience in addition to technical ability.

In short, the products designed and developed should make you very satisfied. If you are not satisfied, don't expect customers to be satisfied. Of course, expect a little higher.

Let me talk about my personal feelings based on the experience of product development, hoping to get criticism and guidance.

1. Before product development, we must fully understand the market demand and roughly determine the specific customer base. Don't spread too large a network and take care of too many customer needs, otherwise it will bring a lot of workload and more consideration to the subsequent development work (especially in the case of insufficient R&D engineers). First make the product suitable for one or two occasions and try it out, seize the market first, and then improve and expand the performance and function of the product according to the customer's usage and other needs.

2. Products are ultimately used, especially industrial outdoor products, and the harsh application environment must be considered. These factors should be fully considered in the initial design to ensure the stability and reliability of the products developed in the future. You can't take chances and wait until you have a problem to solve. In all aspects of design, if the module can be tested temporarily, test it first, find the problem as soon as possible and solve it. Don't wait until the whole system is assembled, otherwise it will be difficult to locate possible problems, which is very important for engineers who have just made products.

Don't run away from the problems you encounter. If the problem is not solved, it will always exist there and will be exposed sooner or later. For responsible engineers, this is a heart disease, and they may be upset and feel guilty when they see it, so for their own safety, it is better to solve it early. When one's personal ability is limited, he can talk about the problem and ask his colleagues around him to help him find a way. In addition to particularly difficult technical problems, one can usually solve them well and quickly, and can also learn from other people's thinking methods.

4. After the product design reaches a certain stage, some people (leaders or customers) may request or suggest adding some more functions, which may disrupt the design ideas and processes of the product. At this time, we should carefully consider their demands. Non-essential functions can be omitted temporarily, but they must be written down and considered later when improving.

5. The process of product design is also a self-improvement process. For novices, they should not only think about making products, but also think about and summarize the problems and knowledge they encounter. They should prepare notebooks and pens, write down problems, solutions and new knowledge at any time, and constantly enrich their technical ability and experience. Everyone's life is actually there? Writing? Their own history books (whether expressed in their minds or in words) can be published if someone writes well and brilliantly. This also belongs to a kind of capital, right? Writing? If you have more, you will have more confidence and courage in both job hunting and promotion in the future.

6. Work attitude and behavior habits are very important. Good habits can make you deal with problems quickly and keep things related to product development under control, while bad habits will make you spend a lot of time doing unnecessary things. This attitude is especially obvious when a team cooperates with others to complete a task. As long as you have enough time and ability, you must do it early. Don't let others run to the front and stare at you several times before doing it.

No one likes to be chased by someone because of one thing, so it is better to finish it early in order to relax, because things have to be done, and doing it late will affect others' views on themselves. It seems that it is not easy to be an engineer.
