摘要

随着直流电力技术的不断发展

直流断路器在高、低压直流电网中的重要性日益明显

直流断路器的试验技术与试验回路设计、实施也成为容量试验站研究的热点。文中分别讨论了中低压直流断路器、高压直流断路器的电流开断技术、开断要求

以及开断试验回路的设计、实施和试验技术。所设计的中低压直流断路器电流开断试验回路一期调试结果为额定电压2 kV、额定短路电流82.6 kA/峰值126.2 kA

完全满足1.8 kV/80 kA直流断路器的试验需求

此外根据设备参数理论上的试验容量可以满足额定参数4 kV/125 kA直流断路器的试验需求。进一步讨论了高压直流断路器电流开断的合成和直接试验回路

并给出了以直接试验回路进行试验时的典型试验结果。文中的研究内容为大容量试验站进行中低压和高压直流断路器电流开断试验回路设计和试验实施具有一定的参考价值。

Abstract

With the development of DC power technology

DC circuit-breakers play a key role in the high and low voltage DC power system

the test technology and test circuit have become the hot topic in the high power laboratory.This paper discusses the DC current interruption technology and test circuit of medium-low and high voltage DC circuit-breaker respectively.The test capability of medium-low voltage DC circuit-breaker is proved to be 2 kV/82.6 kA with peak value of 126.2 kA

which can meet the test requirements of 1.8 kV/80 kA DC circuit-breakers.Additionally

the direct and synthetic test circuits of high voltage DC circuit-breakerare provided

and the typical test results of direct test circuit are given.The research of this paper helps low voltage and high voltage DC circuit-breaker current interruption test circuit designin high power laboratory.
