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 circuitbreaker has attracted more and more attention. In this paper

the design of three kinds of long-stroke PMA is proposedfor 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 theminiaturization of PMA

while optimizing the characteristics of PMA and ensuring the reliability of PMA

the productioncost 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.
