摘要
区域选取择性联锁技术作为智能型断路器的功能之一,是为了解决电网线路中,断路器的选择性保护和速动性之间的矛盾而产生的一项新技术。其能很好地解决短路保护的级间问题,从而有效地提高配电系统的安全性和可靠性。本文分析了在不同故障下断路器的动作情况,并阐述了区域选择性连锁(ZSI)的基本原理和优点,对其在应用中有可能出现的问题做了相关分析。
Zone selective interlock as one of the functions of intelligent breaker. This new technology is generated in order to solve the contradiction between the breaker selective protection and the operation speed of the power circuit. It can be a good solution to the problem of short circuit protection between stages, thereby effectively improving the safety and reliability of power distribution system. This article analyzes the different fault circuit breaker operation condition, and elaborated the zone selective interlock (ZSI) of the basic principles and advantages, in its application problems are likely to arise as relative analysis.
