| 摘 要： | CSL100系列微机保护作为第三代微机保护，在110kV至330kV电网中广为应用，该系列微机保护在现场应用中表现出了较为突出的性能，但同时也存在有一些缺陷，本文就该系列保护在弱电源端保护电流选相元件失效，突变量保护(CSL102)在开关带负荷手跳时易误发允许信号造成对侧保护动作的问题，高频位置停信、其它保护停信回路及保护PT断线判据存在的问题及改进方法进行阐述，从硬件和软件上提出有效解决传统高频停信回路存在的缺陷，以确保高频保护工作的可靠性。

| Abstract: | The type of CSL100 lines protecting devices was used to HOkV and 330kV electric system widely. But it had some disfigurements. Sometimes the signal being break off in high frequency station took place. An improvement method for high frequency signal breaking loop has been expatiated. |
