Types of electricians

Usually, electricians are divided into: outside electrician, inside electrician, installation electrician, maintenance electrician, operation duty electrician, instrumentation electrician and so on, they are independent and interconnected.

1, outside electrician

Outside electrician is engaged in overhead lines, outdoor power distribution equipment, cable line installation of electricians. Generally large substation, more outside electricians.

2, inside the line electrician

Inside the line electrician is engaged in indoor power distribution equipment, indoor lighting and power electrical lines, indoor electrical equipment and components installation electrician. Such as power distribution indoor high and low voltage switchgear, distribution cabinet installation.

3, adjustment test electrician

Adjustment test electrician is engaged in the electrical equipment components and lines to adjust the test and power test, test run electrician.

4, maintenance electrician

Maintenance electrician is engaged in the electrical equipment, components and lines for repair, maintenance, overhaul, repair, as well as general fault diagnosis and treatment, replacement of equipment, components and lines of electricians. That is, high and low voltage switchgear, distribution boxes and other electrical equipment repair and maintenance.

5, operation duty electrician

Operation duty electrician refers to the substation and distribution equipment and lines for monitoring, control, adjustment, recording its operating status and technical parameters of the electrician.

6, motor repair electrician

Motor repairman or clampman refers to the repair of damaged electrical equipment and components, so that it returns to the original good condition performance, to maintain the original technical parameters and safe use and operation of the electrician.

7, electrical instrumentation

Electrical instrumentation refers to all types of electrical instrumentation calibration, verification, repair and installation of electrical wiring.

8, radio workers

Radio workers are engaged in wireless transmitting and receiving system installation, debugging, maintenance, repair work of electricians.

9, instrumentation electrician

Instrumentation electrician or instrumentation refers to the temperature, pressure, flow, level, mechanical and other non-electric measurement, regulation, control equipment and line installation, commissioning, operation, maintenance, repair, calibration work of electricians.

Expanded

The basic principle of electrical indication instrumentation is to be measured or non-electrical quantities are transformed into the indication of the instrumentation activity part of the deflection angular displacement. Measured often can not be added directly to the measurement mechanism, generally need to be measured into the measurement mechanism can measure the transition quantity. This component of the measured amount of conversion into a transition called the measurement line.

The transition quantity according to a certain relationship between the conversion into the deflection angle of the organization called measuring mechanism. Measuring mechanism has an active part and fixed part of the composition, it is the core of the instrument. Electrical indication instrumentation generally has a measuring line and measuring mechanism of these two parts.

The main role of the measurement mechanism is to produce the instrument to deflect the indicator of the rotating torque, as well as the indicator to maintain balance and rapid stabilization of the reaction torque and damping torque.
