摘要
研制了一种新型三路复合开关。将晶闸管和磁保持继电器并接,利用STC12C5410芯片控制复合开关在零电压投入、零电流关断。该复合开关解决了电网中因电容组的投切造成的电流冲击与电压振荡问题,在降低装置成本和体积的同时,提高了可靠性。
A novel three-channel compound switch was developed.With thyristor paralleling magnet hold relay,the ZVS/ZCS of compound switch was realized by the control of STC12C5410.The compound switch could solve the problems of impact current and the shock voltage caused by the capacitors switching,with advantages of small size,low cost and high reliability.
