摘要
针对目前单独利用接触器和电力电子器件在无功补偿装置中存在的种种问题,利用双向可控硅与磁保持继电器的优点,研制了一种基于PIC单片机的高效电容无功补偿投切开关,并对其设计的组成原理、部分电路的结构、时序和性能等进行了详细介绍.
In order to overcome the disadvanta- ges of VAR compensation device made by contactor or power electronic component, the circuit based on triac and magnetic latching relay controls capacitances for VAR compensation hurl - slices switch by PIC chip computer, and its property, time sequence is tested.
