摘要
避雷器作为电力设备的过电压保护装置,其性能的优劣对电力设备安全运行起着很大作用。针对避雷器传统在线监测时现场数据不能及时传输,导致故障不能及时的预测、报警和处理等问题,提出了一种基于GPRS的氧化锌避雷器远程在线监测系统,并利用谐波分析法来诊断MOA运行状态。实际测量表明本文所设计的监测系统具有较高的测量精度,可以实现对MOA状态的远程监测。
The arrester is over voltage protection device for the power equipment, and its performance has great influence on the safe operation of power equipments. The traditional online monitoring method can not transmit the measured data in time, and the malfunction of MOA cannot be forecasted, alarmed and treated. To solve the above problem, a method of remote monitoring system for MOA based on GPRS was brought out in this paper. The system diagnosed the operating MOA status with the method of harmonic current Analysis. The actual measuring results indicate that the monitoring system has the high accuracy, and can be used to realize the remote monitoring for MOA.
