摘　　要：作为中低压母线快速保护的电弧光保护系统在国内已经应用了几年,但还没有得到推广。文中从电弧光保护的基本原理入手,探讨了在各种主接线方式下电弧光保护系统的配置方案,力求用最小的成本和最简单的接线达到保护配电装置安全运行的最大要求,以期得到更广泛的应用。The arc light protection system for rapid protection of medium-/low-voltage bus has been applied in our country for several years,but it has not been generalized.In this article,based on the basic principle of arc light protection,configuration schemes of arc light protection system under all kinds of main wiring modes are discussed,in order to achieve the highest operating safety of power distribution unit with the minimum cost and the simplest wiring mode,so that the arc light protection system can be more widely applied.
