摘要:

介绍了断路器选择性保护的基本概念,以及进行断路器选择性保护研究对于保障供电连续性和可靠性的重要意义。针对某船电力系统,运用时间-电流特性曲线设计了断路器参数。搭建了五级断路器试验平台,验证从上而下五级断路器之间选择性,发现存在旁路缺陷。最后,提出了一种改进的时间-电流特性曲线,可实现选择性保护,并通过试验验证。

关键词: 断路器, 电力系统, 时间-电流特性曲线, 选择性保护

Abstract:

The basic concept of selective protection for circuit breakers,and the important significance of conducting research on selective protection for circuit breakers to ensure power supply continuity and reliability were introduced.A circuit breaker parameter was designed using the time current characteristic curve for a certain ship’s power system.A five level circuit breaker test platform was built to verify the selectivity between the five level circuit breakers from top to bottom.it was found that there were bypass defects.Finally,an improved time current characteristic curve was proposed to achieve selective protection,which was verified through experiments.

Key words: circuit breaker, power system, time-current characteristic curve, selective protection
