The power transmission sequence of high voltage switchgear

Jul 22, 2022

High-voltage switchgear is an electrical equipment mainly based on circuit breakers. Refers to the manufacturer's assembly of related high and low voltage electrical appliances (including control electrical appliances, protection electrical appliances, measuring electrical appliances), as well as busbars, current-carrying conductors, insulators, etc. According to the requirements of the primary electrical wiring diagram, it is installed in a closed or open metal cabinet as a device for receiving and distributing electrical energy in the power system.

The power transmission sequence of the high-voltage switchgear is: PT cabinet → metering cabinet → 10kV high-voltage incoming cabinet → transformer high-voltage incoming cabinet, power-off sequence, transformer high-voltage incoming cabinet → 10kV high-voltage incoming cabinet → PT cabinet → metering cabinet.
