康明斯发电机组的保护范围及功能

作者:康明斯发电机厂家 发布日期:2016-08-23 来源:www.0755fdjz.com 点击:

 康明斯发电机组已有几十年的历史.康明斯无论在设计还是制造上已经被人们认定为知名品牌,是世界引擎领域的高科技典范,下面向大家介绍一下康明斯发电机的保护范围及功能特点浅谈:

 
 在康明斯发电机两侧(中性点侧与出口开关侧)装有两组变比相同的电流互感器,康明斯发电机组按环流法连接将该相的差流回路接入电流继电器,在正常或保护范围外发生短路故障时,中性点与出口侧的电流数值和相位都相同,差流回路没有电流或极小,继电器不会动作;而当保护范围内发生故障时,将产生一个回路差流,当其超过电流继电器整定值时即启动康明斯发电机纵差保护动作。康明斯发电机组都是星形连接,正常情况下,每相定子线圈进线端和尾端(星点)电流是一样的,当定子线圈发生故障,匝间短路、相间短路、绝缘不好等故障时,定子线圈进线端和尾端(星点)电流就不一样大,接在进线端和尾端(星点)的电流互感器器就会产生电流差。
引起差动继电器动作跳闸,这就是差动保护。出线侧的电流互感器一般是接在发电机出口开关前,另一个接在靠近星点的地方,保护范围是康明斯发电机出口开关至星点,纵差动保护主要反应发电机定子绕组及其引出线的相间短路故障,动作于瞬时跳发电机出口开关、灭磁及停机。
