Product Description
The circuit breaker has an arc extinguishing device, so the circuit breaker can handle the load, not only the load current, but also the fault(short circuit) current. The circuit breaker has a good encapsulation form, so simply observe the circuit breaker, can not intuitively determine that it is in a closed or disconnected position.
The isolation switch has no arc extinguishing device, although the rules stipulate that it can be operated in cases where the load current is less than 5A, but it is generally not load-bearing. But the isolation switch structure is simple, it can be seen at first glance from the appearance of the state of operation, when overhauling obviously break point.
The circuit breaker is referred to as “switch” in use, and the isolation switch is referred to as “switch” in use.
Isolation switch
Function:
It is mainly used for “isolation power supply, turndown operation, for connecting and cutting off small current circuit”, without arc extinguishing function.
The isolation switch, usually referred to as the high voltage isolation switch, is rated voltage above 1kV isolation switch, is the most used high voltage switch electrical appliances, working principle and structure is relatively simple, but because of the high usage, high reliability requirements, the design, construction and safe operation of power substation, power plant has a great impact.
