摘要
为提高开关失灵保护的正确动作率， 结合电网的实际情况， 就失灵保护接线中目前普遍存在的发电机热工保护与失灵保护的逻辑关系、三相操作开关的失灵保护、瓦斯与失灵保护的逻辑关系等问题进行了分析，
In order to improve the correct operation rate of breaker failure protection,this paper,associated with actual conditions of Hebei Southern Grid,discusses the commonly existed problems involving breaker failure protection,such as the logic relation between breaker failure protection and I&C protection,that between transformer gas protection and breaker failure protection,and the three phase operated breaker failure protection.Suggestions to solve these problems are proposed.
