What is the function of the disconnecting switch?

The disconnecting switch is a power switch device, which is an important part of the power system.

The disconnecting switch can isolate the power supply during the maintenance of the power system to protect the safety of the operator. It can also be used for line separation of the power system, that is, switching operation. After disconnecting the circuit breaker, the circuit can be separated through the disconnecting switch to change the operation mode of the power grid. In addition, the disconnecting switch can also be used for voltage detection and electrical maintenance. For example, the measurement of the voltage circuit can be achieved by switching the voltage transformer. When repairing some electrical appliances in the power system, the bypass current can be cut off by the bypass disconnecting switch, and at the same time, other electrical appliances in the power system are not affected. In this way, the maintenance process will not affect all equipment, ensuring the continuity of the power supply system.
