摘要
Abstract
126 kV high voltage circuit breaker(VCB) is widely used in substation and power plant construction in our country.With the continuous development of the high voltage level of the vacuum breaking technology and long-stroke permanent magnet actuator(PMA),the research and analysis of 126 kV high voltage permanent magnet vacuum circuit breaker has attracted more and more attention.In this paper,the design of three kinds of long-stroke PMA is proposed for a new type of 126 kV high voltage permanent magneticvacuum circuit breaker,and through the trial prototype test,fully proved the correctness of the design direction.The design of three kinds of long-stroke PMA highlights the miniaturization of PMA,while optimizing the characteristics of PMA and ensuring the reliability of PMA,the production cost of PMA can be greatly reduced and the assembly of PMA can be greatly convenient.It lays a foundation for the engineering application of 126 kV high voltage permanent magnetic vacuum circuit breaker.关键词
