VM1断路器

VM1是首个结合浇铸在环氧树脂中的免维护真空灭弧室、免维护永磁操动机构、免维护电子控制器以及传感器结并且不用辅助开关的真空断路器。

VM1断路器的用途广泛， 可在配电系统里用作控制及保护电缆、架空线、配电站、电动机、变压器、发电机和电容器等设备，适用于工业、化工厂、钢厂、造纸厂、机场、购物中心及其他领域。

  Vacuum circuit-breakers of type VM1 find universal applications in medium voltage range. Their innovative permanent magnetic actuator facilitates a drastic reduction in the number of parts, thus high reliability and sturdiness. An electronic controller with sensors monitors all the functions of the circuit-breaker and its own functional reliability. VM1 technology provides the optimum solution for extremely high number of switching operations including freedom from maintenance as a standard feature.
