Indoor Type Isolation Switch

Timetric Indoor Type Isolation Switch  Introduction

Isolation Switch is a kind of switch device which is mainly used for "isolating power supply, switching operation, connected sum cutting off small current circuit" and has no arc extinguishing function. When the isolation switch is in the open position, there is an insulation distance between the contacts that meets the specified requirements and obvious disconnection marks; When in the closed position, a switchgear capable of carrying the current under normal circuit conditions and the current under abnormal conditions (such as short circuits) within a specified time. Generally used as a high-voltage isolation switch, that is, an isolation switch with a rated voltage above 1kV. Its working principle and structure are relatively simple, but due to its large usage and high reliability requirements, it has a significant impact on the design, establishment, and safe operation of substations and power plants. The main characteristic of the isolation switch is that it has no arc extinguishing ability and can only open and close the circuit without load current. The entry introduces the functions, characteristics, types, applications, error prevention improvements, maintenance, common problems, etc. of isolation switches.

Timetric Indoor Type Isolation Switch Feature And Application

Main function: Breaking and connecting lines without load.

1. Used to isolate the power supply and disconnect the high-voltage maintenance equipment from the live equipment, so that there is a clearly visible disconnection point between them.

2. The isolation switch is combined with the circuit breaker to perform the switching operation according to the needs of the system operation mode, in order to change the system operation wiring mode.

3. Used to connect or disconnect small current circuits.
