摘要
介绍了无功补偿调试装置的工作原理和功能要求,通过对工厂原有普通通电试验台的改造,利用三相电压之间的相位关系及电压电流的转化来实现电流相位的调节,采用过电压继电器作为启动元件,电秒表作为计时元件,构成了过电压保护和计时功能检测电路,从而有效地解决了无功补偿设备的出厂试验问题。
Introduction was made to the working principle and functional requirements of the debugging device for the reactive power compensation equipment complex. Via rebuilding factory＇s existing normal electrical test device, phase relation between three-phase voltages and transform between voltage and current were adopted to realize adjustment of current phase. Overvoltage relay adopted as start element and electronic second watch adopted as timing element constituted overvoltage protection and time-keeping functional test circuits, so that the predelivery test problems for reactive power compensation devices were solved effectively.
