Switchgear part

There are many electrical components in the high voltage switchgear, which can generally be divided into two categories: primary electrical components and secondary electrical components:

1, switch cabinet commonly used primary electrical components (main circuit equipment) mainly include current transformer, voltage transformer, ground switch, arrester (resistance and capacitance absorber), isolation switch, high voltage circuit breaker, high voltage contactor, high voltage fuse, transformer, high voltage live display, insulation (through the wall sleeve, contact box, insulator, insulation heat shrink sheath), high voltage reactor, load Switches, high-voltage single-phase shunt capacitors, etc.

2, the main secondary electrical components commonly used in the switch cabinet Secondary electrical components refer to the equipment for monitoring, control, measurement, adjustment and protection of primary equipment, mainly relays, watt-hour meters, ammeters, voltmeters, power meters, power factor meters, frequency meters, fuses, air switches, transfer switches, signal lights, resistors, buttons, microcomputer integrated protection devices.
