MOA Potential Distribution and Temperature Distribution Test System Based on Wireless Acquisition Technology

避雷器(MOA)的过电压保护特性对电网设备的安全运行起到关键作用,其中MOA的电位分布和温度分布情况是评判整支避雷器的重要指标。通过合理的均压措施,能够大幅延长避雷器使用年限,在均压调整前首先需对避雷器的电位分布情况进行准确测试。本项目引入8位精简指令微控制器,无线通信、同步采集方式,完成基于无线采集技术的MOA电位分布及温度分布系统的设计,使测试现场繁琐的光纤布线得以简化,同时保障了测试数据的准确性。根据MOA测试到的电位分布及温度分布结果,为采取MOA均压措施提供了试验依据,保障了电网的安全可靠运行。

The overvoltage protection of the lightning arrester （MOA） plays a key role in the safe operation for power grid equipments.The distribution of the potential and temperature distribution of MOA is an important index to judge the whole arrester. Through reasonable mean pressure measures,the service life of the arrester can be extended greatly. The potential distribution of the arrester should be tested accurately before the pressure adjustment.This project introduces 8 bit simple instruction microcontrollers,wireless communication and synchronous acquisition.It completes the design of MOA potential distribution and temperature distribution system based on wireless acquisition technology,which makes the tedious fiber wiring simplifying and ensures the accuracy of test data. According to the results of potential distribution and temperature distribution measured by MOA,it provides experimental basis for adopting MOA voltage sharing measures and ensures the safe and reliable operation of power grid.
