鉴于目前高压开关柜测温技术存在非常大的弊端,根据无源无线传感技术的原理,提出了一种基于新型的无源无线传感技术的高压开关柜温度在线监测新方法.该方法采用分层设计:高压室层和变电站层,高压室层进行温度测量,变电站层后台软件将温度信号进行整理、分析、显示、存储和打印等.目前该系统已经应用于钦州供电局220 kV港口和110 kV广场、果子山等变电站,运行稳定、效果良好,成功地消除了多起安全隐患.%Because there are lots of limitations in current switchgear temperature test methods, a new supervision system of the switchgear temperature based on passive wireless sensor is introduced. The system is hierarchical design, including switch-gear layer in which the temperature is measured, and monitoring layer in which the temperature signal can be resoursed, analyzed, displayed, stored in database and printed through the backstage software. This system has been already put into use in 220 kV Gangkou Substation, 110 kV Guangchang Substation, and so on, which proves its standid performance and good effect, and sucessfully solves several hidden problems.
