summary
RBS1-12 indoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an indoor switchgear used in 12kV power system, as the protection and control unit of power grid equipment, industrial and mining enterprise power equipment. Due to the special advantages of vacuum circuit breaker, it is especially suitable for the frequent operation of rated working current or the place where the short circuit current is cut off for many times.
The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or a special propulsion mechanism to form a handcart unit. The fixed circuit breaker can increase the corresponding interlocking to meet the needs of XGN2, GG1A and other fixed cabinets.
The circuit breaker meets the requirements of GB1984-2014 AC high voltage circuit breaker, JB3855-1996 3.6-40.5KV indoor AC high voltage vacuum circuit breaker, DL/T403-2000 12kv-40.5kv high voltage vacuum circuit breaker ordering technical conditions, and meets the relevant requirements of IEC56 (87 publication).
