中文摘要	应用在基于电压源型换流的多端直流输电系统中的高压直流断路器,其关键部件机械式快速隔离开关在断路器开断故障电流时需要在几ms内分闸到位。为此,提出了基于电磁斥力的快速驱动器作为快速隔离开关的操动机构。通过对电磁斥力机构的线圈、金属盘、控制电流和行程特性的基于等效电路法的建模仿真及装置试验,研究了其在几ms内操动行程达25 mm的可行性。结果表明:仿真结果和试验结果具有一致性;电磁斥力快速驱动器的操动行程能在几ms内达到25 mm。在验证了仿真方法正确的基础上,根据仿真结果提出了电磁斥力机构的一般设计原则:线圈的内径和金属盘的内径,线圈的外径和金属盘的外径都应该设计成一样大;金属盘的厚度对于不同的设计对应有最优的参数;线圈和金属盘的初始距离应尽量小。; As a key component of the HVDC circuit breaker used in voltage source converter based multi-terminal HVDC(VSC-MTDC) transmission system, mechanical fast disconnector needs to complete opening in a few milliseconds when the HVDC circuit breaker interrupts the fault current. Hence, we proposed an ultrafast driver with electromagnetic repulsion mechanism as the actuator for fast disconnector. We studied the electromagnetic repulsion mechanism's coil, metal disk, control current and displacement characteristics through numerical simulation based on the equivalent circuit method and some experiments with prototypes, and discussed the possibility of the actuator stroke reaching to 25 mm in few milliseconds. It is found that the results of numerical simulation are in accordance with the experimental results, as well as that the actuator is able to actuate 25 mm in a few milliseconds. By using the verified simulation method, some general principles for designing the electromagnetic repulsion mechanism based on the simulation results can be proposed: the inner diameter of coil should be the same as that of metal plate, so is the outer diameters of coil and metal plate; the metal plate has optimum thickness according to different mechanisms, while the initial distance between coil and metal plate should be as small as possible.
