摘要:
基于电磁斥力机构的快速机械开关是混合式高压直流断路器的核心设备之一,其几毫秒内分闸到位的速动性对直流断路器至关重要,然而其速动性对开关的缓冲提出了更高要求。文中提出了一种适用于电磁斥力机构分闸过程的电磁缓冲方法,介绍了电磁斥力机构和电磁缓冲的基本工作原理,并建立电磁斥力机构电磁缓冲装置的有限元模型,结合其原理仿真分析了缓冲储能电容容量、初始电压和缓冲触发时间对电磁缓冲性能的影响规律。最后对舟山示范工程200 kV直流断路器用快速机械开关进行了电磁缓冲试验,验证了仿真分析的正确性。文中对电磁缓冲的设计和控制提供了一定的指导。
Abstract:
The fast mechanical switch based on the electromagnetic repulsion mechanism is one of the core equipment of hybrid HVDC breakers. The rapidity of the switch that completes the opening in a few milliseconds is crucial to HVDC breakers. However, a higher requirement of damping is need for the switch because of the rapidity. This paper presents an electromagnetic damping method that is suitable for the opening of the electromagnetic repulsion mechanism. The basic principle of electromagnetic repulsion mechanism and electromagnetic damping is introduced. And the finite element model of electromagnetic damping is established. Based on the principle, the influence of the damping capacitor capacitance, the initial voltage and the damping triggering time on the performance of the electromagnetic damping is simulated and analyzed. Finally, the test of electromagnetic damping device has been done on the fast mechanical switch of 200 kV DC Circuit Breakers of Zhoushan Demonstration Project, and the correctness of the simulation analysis was verified. This paper provides guidance for the design and control of the electromagnetic damping in some degree.
