Product Description

Isolating switch [1] (Isolating switch) is a switch device mainly used for "isolating power supply, reversing operation, connecting and cutting off small current circuits", without arc extinguishing function. When the switch is in the sub position, there is an insulation distance between the contacts and an obvious disconnection mark, and when it is in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (e.g. short circuit) within a specified period of time. It is generally used as a high-voltage disconnecting switch, i.e. a disconnecting switch with rated voltage above 1kV. Its own working principle and structure are relatively simple, but due to the high usage and high working reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants. The main feature of disconnect switches is that they have no arc extinguishing capability and can only divide and close circuits without load current. The term introduces the functions, characteristics, types, applications, error-proof improvement, maintenance, and common problems of disconnect switches
