调容式消弧线圈投切开关触发电路的分析设计

摘要

Introduction was made to the working principle of adjusting capacitance arc extinction compensation based on silicon-con- trolled switch. This paper analyzed the switching mode of silicon-controlled switch, giving the silicon-controlled triggering circuit dia- gram and its simulative waveform. Practice shows that in adjusting capacitance arc extinction coil grounding device, silicon-controlled capacity disposition is convenient and flexible, strongly adaptable to power grid, being able to precisely measure on-line grounding capacitance current in real time.%介绍了基于可控硅开关的调容式消弧补偿装置的工作原理，分析了可控硅开关的投切方式，给出了可控硅触发电路图及其仿真波形。实践证明，调容式消弧线圈接地装置中，可控硅容量配置方便、灵活，对电网的适应能力强；实时在线测量对地电容电流，结果准确。
