How to improve equipment quality and further reduce equipment failures by strengthening daily maintenance of equipment?

Improve the flexibility and reliability of system wiring; Improve the availability of equipment, including equipment factors, human factors and external factors; Improve the rationality of operation mode; Ensure the adequacy of power capacity and reserve capacity. (2. 1) Strengthen the transformation of power grid and improve the reliability of power supply. In 2009, China proposed to build a strong smart grid. To build a strong smart grid, we must increase the intensity and speed of grid transformation. From the point of view of power system, this is also the key to improve the power supply reliability of power system. In the planning, design and construction of power grid transformation, when it comes to economy and reliability, power supply reliability must be given priority. Moreover, the importance and particularity of the main network must be fully considered in the process of transformation, so that it can meet the N- 1 principle, and the special area needs to meet the N-2 principle. 2.2 relying on scientific and technological progress to improve the reliability of power supply. (1) propulsion state maintenance, power outage maintenance according to actual needs. With the strengthening of power grid transformation, new electrical equipment with high reliability and maintenance-free is gradually adopted in the power grid, and the traditional scheduled maintenance can no longer meet the needs of operating equipment. Therefore, a more reasonable maintenance mode-condition-based maintenance has gradually replaced the traditional maintenance mode and become the mainstream. Condition-based maintenance is to determine whether the equipment needs overhaul through comprehensive analysis according to the operation situation, test results and structural characteristics of electrical equipment. Its basic idea is to keep electrical equipment running for as long as possible. (2) Carry out research on live working under safe conditions to reduce the power failure time of equipment. Live working refers to operating high-voltage electrical equipment without power failure. Live working includes live testing, live inspection and live maintenance. Live working is one of the most technical projects in equipment maintenance, which requires not only the technical skills of operators, but also the psychological quality of operators. 2.3 Establish an integrated automation system for distribution network to improve the reliability of power supply. By upgrading the existing distribution network, the automation of the distribution network can be realized, so that once the distribution network fails, the automation system can act immediately to isolate the fault section, and at the same time, the non-fault section can automatically restore normal power supply. Distribution network automation system not only greatly shortens the fault finding time, but also compresses the range of fault influence to a certain range, so that the whole distribution network is not affected. If equipped with mechanized repair team, the time of power outage due to power system failure can be further shortened. At the same time, the integrated automation system of distribution network can also provide decision-making basis for condition-based maintenance and power market opening, thus greatly improving the flexibility of distribution network and further improving resource utilization. 2.4 Strengthen line insulation to improve power supply reliability. Due to the uncertainty of environmental factors, the frequency of power outage maintenance caused by overhead line faults is high, which accounts for a large proportion in the influence of power outage maintenance of power supply equipment on power supply reliability of power system. Therefore, improving the insulation level of transmission lines can effectively improve the power supply reliability of power systems. 3. Organizational measures to improve the reliability of power supply 3. 1 Improve the reliability management network and raise the awareness of reliability management. (1) The reliability of power system is related to the national economy, and reliability management runs through the whole production process. Therefore, reliability professionals should not only love their jobs and work hard, but also have a certain level of education, actively go deep into production, understand all aspects of production, and master the operation methods of microcomputers and the use of corresponding management application software. Therefore, the selection of full-time reliability personnel is related to the normal operation of the whole reliability management network and is the key to the perfection of the whole management network system. (2) Power supply reliability management of power system involves various industries and departments of production, and the whole system is a unified whole. Only with the full support and coordination of all parties can the reliability management network work smoothly. Therefore, scientific management methods must be adopted to provide a good working environment for reliability professionals to ensure the normal and smooth operation of the reliability management network. (3) Electric power enterprises not only need to formulate strict rules and regulations according to the national regulations and industry standards on electric power reliability, but also need to strengthen the corresponding organizational management level, establish and improve the regular meeting system of enterprise reliability, and unify the responsibilities, rights and interests of corresponding personnel. So as to improve the awareness of all relevant personnel and the professional level of reliability professionals. 3.2 Focus on the reliability of power supply and optimize the management of power outage maintenance. (1) The maintenance of electrical equipment in power system is related to the reliability of power supply. Therefore, every maintenance should be arranged reasonably, and the maintenance construction plan should be carefully formulated and strictly controlled. Before making the construction plan, we should fully consider the actual situation of the operation to determine whether to carry out power outage or live operation. Then consider whether different power outage projects can be arranged to work together through mutual coordination and cooperation, so as to effectively reduce the number of power outage maintenance. (2) While optimizing outage maintenance, reliability application analysis should be strengthened. We should not only count the reliability after the event, but also calculate the reliability index before using these data. And use scientific methods to gradually improve the monitoring ability, in order to achieve the ability to predict in advance and achieve target management. 3.3 Strengthen operation and maintenance management, and enrich the power of fault repair. (1) Reducing the failure rate of electrical equipment is a powerful measure to improve the power supply reliability of power system. Therefore, we must actively prevent various factors that affect the normal operation of electrical equipment, and find and eliminate the defects of electrical equipment in time. For transmission lines, it is necessary to continuously strengthen their operation and maintenance management, especially to strengthen the control of external damage, eliminate potential safety hazards as much as possible, and reduce the impact of electrical equipment failure on power supply reliability. (2) Power system failure is inevitable. Therefore, power supply enterprises must, according to their own actual situation and different areas under their jurisdiction, increase emergency repair personnel to deal with sudden failures while ensuring appropriate daily maintenance teams. It is necessary to regularly train emergency repair personnel and formulate corresponding treatment plans for possible failures. Usually, we should not only increase the investment in fault handling instruments, but also organize relevant personnel to conduct accident drills regularly to effectively improve work efficiency and exercise the quick response ability of the emergency repair team. )
