摘　　要：为实现TV二次回路全面有效的实时监测,避免TV二次回路异常造成保护及安全自动装置的不正确动作,本文通过对TV二次回路异常情况的分析,采用分流法的原理,提出了一种检测TV二次回路的方法,研究开发了TV二次回路在线监测装置。在220 k V平胜站的试运行结果表明,本TV二次回路在线监测装置能够准确无误地反映TV二次回路的运行状态,及时发现TV二次回路异常缺陷。To realize real-time monitoring of TV secondary circuit comprehensively and effectively, avoid protection and automatic safety device incorrect action caused by abnormal TV secondary circuit, this paper puts forward a method to detect TV secondary circuit, researches and develops a online monitoring device of TV secondary circuit base on analysis of TV secondary circuit abnormal situations and the principle of shunt method. The results of trial operation in the 220kV Pingsheng station shows that the on-line monitoring device of TV secondary circuit can reflect the running state of TV secondary circuit accurately and found abnormal defect of TV secondary circuit timely.
