摘要

带有高耦合分裂电抗器（HCSR）的并联高压SF

断路器在大容量开断有潜在的应用前景。短路电流开断试验表明该开断装置均流性能良好

但在开断时间上会存在不同期的问题

出现限流开断现象;为了进一步提高装置开断的可靠性

避免限流开断的发生

通过MATLAB的Simulink模块搭建了电路和电弧模型

研究了断口两端并联电容器对于其开断性能的影响

结果表明断口并联电容能够有效地降低断口恢复电压上升率

从而实现均流开断;最后开展了相关的试验研究

通过在断口两端并联1个0.277μF的电容后

实现了可靠的均流开断。研究结果对于该开断装置的研制具有一定的指导意义。

Abstract

Paralleled high-voltage SF

circuit breakers with a highly coupled split reactor（HCSR） have the potential application for the high fault current interruption.Short-circuit current breaking tests showed that the current-sharing was effective.However

there might be difference in the operation moments or the phenomenon of current-limiting interruption.In order to further improve the interruption reliability of this interrupting device and avoid the current-limiting interruption

a circuit model and an arc model were developed through the Simulink module of the MATLAB.The influence of capacitors paralleled to the breaks on the interruption process was investigated.It was found that the paralleled capacitor was constructive to deduce the rising rate of the recovery voltage

thereby realizing the current-sharing inter

ruption.Morever

relevant experiments were carried out.A capacitor of 0.277 μF was paralleled to one of the paralleled breaks and reliable current-sharing interruptions were implemented.The research results are constructive to the development of this interruption device.
