摘要
基于近年并联电容器装置频繁出现故障的现象和特点,研制出一套电容器故障监测系统,分别提取并联电容器装置的电流和电压实时信号,利用Labview虚拟仪器程序进行软件开发实现在线监测,对获取的电流电压信号进行谐波、合闸涌流、暂态过电压等方面进行分析和研究,并应用于现场测量,给出了一起电容器内部击穿故障的监测实例。
Based on the phenomenon of the emerging faults in shunt capacitors, an on-line fault monitoring system is introduced, and the characteristics and functions are analyzed. The system is of the function of monitoring practical current and voltage signals on-line by Labview programming; the harmonic wave, overvoltage, and close inrush current can be analyzed in the system. What＇s more, a typical fault of a capacitor due to breakdown is discussed in this paper. By this original data the further study on shunt capacitors can be supplied.
