Isolating switch is a switching device that is mainly used for “isolating power supply, switching off operation, connecting and cutting off small current circuits” and without arc extinguishing function. When the isolating switch is in the open position, there is an insulation distance and an obvious disconnection mark between the contacts that meet the specified requirements; in the closed position, it can carry the current under normal circuit conditions and under abnormal conditions (such as short circuit) within the specified time. current switching device. It is generally used as a high-voltage isolating switch, that is, an isolating switch with a rated voltage of more than 1kV. Its working principle and structure are relatively simple, but due to the large amount of use and high requirements for work reliability, the design, establishment and operation of substations and power plants are required. The impact on safe operation is greater. The main feature of the isolation switch is that it has no arc extinguishing ability, and can only divide and close the circuit without load current.
