The working principles as well as advantages and defects of several high voltage thyristor valve overcurrent test circuits in ABB Swiss, ABB Sweden, Toshiba, and Siemens are analyzed and compared. According to CIGRE’s guidelines on intensity of both current and voltage of high voltage valve in series and the requirement of IEC’s test specification on valves of both SVC and HVDC, a novel main circuit scheme for overcurrent test is proposed, in which the heating current is supplied by large current source, the overcurrent and corresponding locking voltage are supplied by resonant circuit, the special test requirements of HVDC valves is auxiliary implemented by high voltage circuit. The adjustment of the proposed test circuit is more flexible, more test modes can be offered and the test ability is also evidently improved. The voltage of the proposed test circuit is raised to 18kV, the overcurrent peak to 47kA, and the expanded frequency range is from 50Hz to 350kHz.

分析和比较了瑞士ABB、瑞典ABB、TOSHIBA和SIEMENS公司的几种高压晶闸管阀过电流试验回路的工作原理及其优缺点。根据国际大电网会议(CIGRE)关于高压串联阀电流电压强度的技术导则以及国际电工委员会关于静止无功补偿装置阀和高压直流阀的试验标准的要求,提出了一种新型过电流试验回路的主电路方案:由大电流源提供加热电流,由谐振回路提供过电流及相应的闭锁电压,由高电压回路辅助实现高压直流阀的特殊试验要求。该试验回路调节更灵活、试验模式更多、试验能力也大为提高:高电压回路的电压参数提高至80kV,过电流峰值提高到47kA,频率范围扩展到50~350Hz。
