【摘要】 高压直流开断试验回路,成本低、结构简单、调节方便,广泛应用于世界各国高压直流开断研究和断路器的检验之中。因此试验回路的等价性便成为高压直流开断研究中的一个重要课题。文章介绍了试验回路的开断过程,并与国际上公开发表的现场开断试验结果进行比较,得出结论:高压直流开断试验回路在电弧能量、电流过零、恢复电压等三个重要方面,符合断流容量试验的等价条件。更多还原

【Abstract】 Because of its economy,simplicity and flexibility,synthetic testing circuit is extremely useful for research of HVDC interruption and HVDC breakertype test.The investigation on the equivalence of this circuit is an impor-tant subject of development on HVDC interruption.The interrupting processof testing circuit was described and compared with the results of field test.It shows that synthetic testing circuit for HVDC interruption accords withthe equivalent conditions of interrupting capacity test in arc energy,currentzero and recovery voltage.更多还原
