摘要

为了研究真空直流强迫过零开断过程中的弧后电流,该文设计永磁-斥力混合式快速机构,搭建直流开断用弧后电流测量系统,开展直流小电流开断实验,研究弧后电流受开断电流幅值、电极开距、换流电流频率及换流电容电压的影响。研究结果表明：弧后电流呈现出不稳定性。弧后电流随开距增大而增大,且同开距下弧后电流变化不大。开断电流小于800A时,弧后电流增长较快;开断电流在800~1 800A范围时,弧后电流增长较慢。弧后电流随着换流频率的增加显著增大,换流频率对弧后电流的影响起主导作用。换流电容电压应控制在一定范围内以减小弧后电流。

Abstract：

In order to investigate the post arc current in DC interruption, the high speed hybrid actuator was designed and the post arc current measuring system was established. Then, experiments were carried out to study the influence on the post arc current, including the amplitude of rated current, electrode gap, commutation frequency and commutation capacitor voltage. The results indicate that post arc current is instable within a certain range. The post arc current increases with the increase of the electrode gap, and is nearly unchanged at the same gap. When the rated breaking current is less than 800A, the post arc current has a high rising rate, while the rising rate of the post arc current decreases when the rated breaking current is in the range of 800~1 800A. The post arc current increases obviously with the increase of the commutation frequency, which determines the amplitude of the post arc current. In addition, the commutation capacitor voltage should also be controlled to reduce the post arc current.

Key words： DC interruption forced current zero post arc current commutation frequency commutation capacitor voltage
