[0002] Isolating switches are an important device in power systems, used to safely isolate circuits for maintenance, overhaul or emergency response. In normal operation, isolating switches allow current to pass through and keep the circuit connected. When the circuit needs to be isolated, the isolating switches can cut off the circuit through manual or automatic operation to prevent current flow and ensure safe operation. The reliability and operational flexibility of isolating switches are crucial to the stable operation of power systems, and can effectively protect the safety of equipment and personnel and prevent accidents.

[0003] The isolating switch is an important safety device used in power systems. It is usually made of insulating materials, including a movable metal blade and a contactor that matches it.
