              HVD11-1.14 Permanent magnet mechanism  INDOOR HIGH VOLTAGE VACUUM CIRCUIT BREAKER

               

              General:

              HVD11-1.14  Permanent magnet mechanism Vacuum Circuit Breaker is mainly used in 1140v or 660v three phases electrical distribution system. Permanent magnet low-voltage vacuum circuit breakers can be operated under the rated current range frequently breaking the short-circuit current, more suitable for use in coal mine feed systems, composed of mining and high voltage flameproof distribution. ALso could use for Large-capacity motors for start infrequently.

              This product uses bistable permanent magnet mechanism + short-circuit magnetic manual opening, simple structure, stable and reliable. Because there is no axle, hook and other mechanical parts, greatly reduced the mechanical parts failure caused by wear and tear, Longer service life.

                HVD11Y-630/1.14-15型永磁机构低压真空断路器主要用于1.14KV或660V三相电网中, 用于分配电能,?{亚博王者荣耀竞猜主词}{亚博王者荣耀竞猜主词};は呗芳暗缭瓷璞?/span>,并可在额定电流范围内进行频繁操作或多次开断短路电流,更适于在煤矿馈电系统中使用,组成矿用一般型及高压隔爆型配电.也可以用作大容量电动机的不频繁启动之用.

              该产品采用双稳态永磁机构+磁短路手动分闸,结构简单,工作稳定可靠.由于没有了半轴,搭钩等机械零件,使得因机械零件磨损造成的故障大降低,提高了寿命.
