浅谈低压智能断路器的脱扣器选型

保护电器在低压配电系统中占有重要地位。保护电器在使用过程中,其选择性是最为重要的。本文主要以低压智能断路器为讨论对象,介绍其是如何实现选择性保护的,并在过程中引出了智能脱扣器的概念,同时对常见的过电流脱扣器、欠电压脱扣器的工作原理和使用方法进行了探讨。

Discussion on Release Selection of Low-voltage Intelligent Circuit-breaker

Protection apparatus plays an important role in the low-voltage electrical distribution systems.The selectivity of protection apparatus is the most important in the usage process.In this paper,the low-voltage intelligent breaker is discussed and describes how it realizes selective protection and introduces the concept of intelligent release in the process.At the same,the working principle and operation methods of the commonly used over-current release and under-voltage release.
