研究了一种由吹气式SF6气体中断单元(GIU)和真空中断单元(VIU)串联组成的混合中断单元(IU)，作为高压直流断路器(HVDC CB)的中断单元。利用混合IU，通过在直流电流上叠加高频反脉冲电流产生电流零点的强制电流注入法，进行了峰值恢复电压420 kV下开断8 kA直流电流的试验。分析了适用于混合IU瞬态恢复电压周期的中断机制。 250 kV -1,200 A 气体绝缘原型高压直流断路器已成功制造并测试。
A hybrid interrupting unit (IU) has been examined which consists of a puffer type SF6 gas interrupting unit (GIU) and a vacuum interrupting unit (VIU) connected in series as the interrupting unit of HVDC circuit breaker (HVDC CB). Using the hybrid IU, a test of interrupting a dc current of 8 kA under a peak recovery voltage of 420 kV was conducted by means of a forced current injection method which superposes high frequency counter pulse current to dc current to produce a current zero point. Interrupting mechanism has been analyzed which applies to the transient recovery voltage period of the hybrid IU. A 250 kV -1,200 A gas insulated prototype HVDC CB has been manufactured and tested successfully.
