摘要
低压断路器作为低压配电系统中最重要的控制与保护元件,主要承担着低压配电系统中过电流保护以及其它各类故障保护。针对目前低压配电系统中经常采用的过电流保护方式,本文对其不足之处和相应的发展趋势进行了探讨。
The low voltage circuit breaker, the most important control and protection component in low-voltage distribution system, mainly undertakes the over current protection and other kinds of emergency protections. Regarding normally used over current protection mode in the existing low-voltage distribution system, this paper mainly discussed about its disadvantages and corresponding development trend.
