| 摘 要： | 基于复合开关投切电容器的无功补偿装置采用过零投切的复合开关模块投切电容器，晶闸管在电压过零时导通，电流过零时关断，避免了合闸涌流的冲击。本文对晶闸管投切时电容器上的能量分布进行了详细的分析，找出晶闸管最佳开通和关断时间，确保晶闸管导通时无合闸冲击电流。

| Abstract: | The device of reactive power compensation based on the compound switchgear of switching capacitor adopts the moduleswitched capacitor with cross zero switching. The thyristor turned on when the voltage crossing zero, turned off when the current crossing zero, avoiding the shock of close inrush current. This article analyzes in detail the energy distribution of capacitor when the thyristor switching, finds out the best time for thyristor turning on and off, ensures that there is no close inrush current when thyristor turning on. |
