摘　　要：针对直流开关器件在容性接通能力、极限分断能力和短路耐受能力的极限性能测试需求,设计了一款新型的满足150~1 200 V直流开关器件极限性能测试系统,包括系统的主回路拓扑设计、控制单元设计、核心器件的设计选型以及操作界面设计。提出了一种通过超级电容存储能量,利用IGBT作为控制单元,满足短时大电流、高功率输出的极限性能测试系统。研制的测试系统响应速度达到微秒级,时间控制准确度小于0.5 ms,满足直流开关在1~12 kA的极限工况性能测试要求,同时解决了该类测试平台对于电网容量的依赖。In order to meet the testing requirements of the ultimate performance of DC switching devices in capacitive switching ability, ultimate breaking ability and short circuit tolerance ability, a new type of ultimate performance testing system for 150~1 200 V DC switching devices is designed, including the topological design of the main loop of the system, and the control unit design, and the design and selection of the core devices, and the operating interface design. A ultimate performance test system which can store energy by ultracapacitor and use IGBT as control unit was proposed to meet the requirements of short-time large current and high power output. The response speed of the test system is up to μs level, and the time control accuracy is less than 0.5 ms, which can meet the performance test of DC switch in the ultimate working condition of 1~12 kA. At the same time, the dependence of the test platform on power grid capacity is solved.
