摘要
立足于智能电网及铁路系统对开关设备的需求,开发出一种全智能馈线用铁道断路器,以永磁机构作为操动机构,采用相控合、分闸操作方式。同时,实现了真空度在线监测、触头触臂无线测温及断路器状态监测等一系列智能化功能。该智能27.5 kV铁道真空断路器可大大减少现场的工作量,提高供电的可靠性,解决了馈线断路器状态检修的难题。
Based on the need for switch of smart power grids and railway system, the writer developed an intelligent circuit breaker used on railway, which use phase controlled permanent magnetic actuator as operating mechanism. The device also has a series of intelligence such as vacuum degree online monitoring. Wireless temperature measurement for switch contact arm and switch condition monitoring, etc. the device can significantly reduce the workload, increase the reliability of power supply, which solved the difficult problem of the circuit breaker achieve condition overhaul.
