Indoor AC high voltage vacuum circuit breaker hereinafter referred to as a circuit breaker is a three-phase AC rated voltage indoor switchgear, which can be used for the control and protection of electrical facilities in industrial and mining enterprises, power plants and substations, and is suitable for places with frequent operations.
The circuit breaker meets the standard requirements of "AC high voltage circuit breaker", 855-1996 "3.6-40.5kV indoor AC high voltage vacuum circuit breaker", DL403-91, "10-35KV indoor AC high voltage circuit breaker ordering technical requirements", and meets The relevant requirements of IEC56 (Publication 87).
The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or a dedicated propulsion mechanism to form a handcart unit.
It is an indoor switchgear with three-phase AC 50Hz rated voltage of 12KV power system. It is used as protection and control unit for power equipment and industrial and mining enterprises. Applicable to places that require frequent operation at rated operating current, or multiple times to break short-circuit current.
The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, and can be used as a fixed installation unit, or can be equipped with a special propulsion mechanism to form a hand truck unit.
Features: small size, light weight, suitable for frequent operation
