Electrician type

Usually electricians are divided into: external electricians, internal electricians, installation electricians, maintenance electricians, operation electricians, instrument electricians, etc. They are both independent and interrelated.

1, external electrician

Foreign electricians refer to electricians engaged in the installation of overhead lines, outdoor power distribution devices and cable lines. Generally, there are many outside electricians in large distribution stations.

2. Internal electrician

Indoor electrician refers to an electrician engaged in the installation of indoor power distribution devices, indoor lighting and power electrical circuits, indoor electrical equipment and components. For example, high and low voltage switch cabinets and power distribution cabinets are installed in the power distribution room.

3, adjust the test electrician

Adjustment test electrician refers to an electrician who is engaged in the adjustment test of electrical equipment components and lines, and carries out power transmission debugging and trial operation.

4, maintenance electrician

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

5, run the electrician on duty

The electrician on duty refers to the electrician who monitors, controls, adjusts and records the running state and technical parameters of distribution equipment and lines.

6, motor maintenance electrician

Motor repairman or fitter refers to an electrician who repairs damaged electrical equipment and components, restores them to their original good state and performance, maintains their original technical parameters, and can be used and operated safely.

7. Electricians and Instrument Workers

Electrical instrument workers refer to electricians who are engaged in the calibration, verification, repair and wiring of various electrical instruments.

8. Wireless electrician

Wireless electrician refers to an electrician who is engaged in the installation, debugging, maintenance and repair of wireless transmitting and receiving systems.

9, instrument electrician

Instrument electrician or instrument worker refers to an electrician who is engaged in the measurement, adjustment and control of non-electric quantities such as temperature, pressure, flow, material level and mechanical quantity, as well as the installation, debugging, operation, maintenance, repair and calibration of equipment and lines.

Extended data

The basic working principle of the electric indicator is to convert the measured electric quantity or non-electric quantity into the deflection angular displacement of the movable part of the indicator. The measured can not be directly added to the measuring mechanism, and it is generally necessary to convert the measured into a transition quantity that can be measured by the measuring mechanism. This part which is converted into transition quantity by measurement is called measuring circuit.

The mechanism that converts the transition quantity into deflection angle according to a certain relationship is called measuring mechanism. The measuring mechanism consists of a movable part and a fixed part, which is the core of the instrument. Electric indicating instrument is generally composed of measuring circuit and measuring mechanism.

The main function of the measuring mechanism is to generate the rotating torque that deflects the indicator of the instrument, as well as the reaction torque and damping torque that make the indicator keep balance and stability quickly.
