VS1 side-mounted series indoor high-voltage vacuum circuit breakers are suitable for three-phase AC 50Hz, rated voltage 7.2~12kV indoor high-voltage switchgear. Used in ring network cabinet equipment, it can replace the sulfur hexafluoride load switch as the incoming switch of the substation and provide backup protection for the outgoing cabinet; at the same time, it can be used as the outgoing switch protection and control the distribution transformer with a capacity greater than 1250kVA It can also be used as a tie breaker for dual power supply lines.
VS1 side-mounted series indoor high voltage vacuum circuit breaker circuit breaker meets the national standard GB1984 "AC high voltage circuit breaker", JB3855 "3.6～40.5kV indoor AC high voltage vacuum circuit breaker", DL403 "10～35kV indoor high voltage vacuum circuit breaker" Ordering technical conditions" and relevant IEC standards, and have reliable interlocking functions.
VS1 side-mounted series indoor high-voltage vacuum circuit breakers can be operated frequently and have the ability to repeatedly break and quickly reclose.
VS1 side-mounted series indoor high-voltage vacuum circuit breakers are designed with front and rear sub-assembly structure, which can be used as a side-mounted fixed installation unit.
