摘要
本文详细讨论了电容器投入核心问题即无冲激电流产生。投切开关要求响应速度迅速、动作可靠,因其工作于上千伏高压,对元件参数选择苛刻。可控硅-继电器开关是投切开关的核心部件,其中又以变压器触发电路最为关键。本文给出硬件设计方案和关键电路原理,给出核心元件的参数选择及设计,经对样机测试,效果良好。
This paper introduces a compound switch with no pulse current during switching of the capacitor. The SCR-Relay switch circuit and the circuit of the triggle transformer are presented. The software of the system is also outlined.
