Abstract
The basic structure and main design parameters of ZW32-12 type pole-mounted vacuum circuit breaker and permanent magnetic actuator are analyzed,focusing on the selection of mechanical characteristic parameters and countermeasures of pole-mounted vacuum circuit breaker,and the design difficulties of permanent magnetic actuator are given.In view of the phase-deficient operation defect resulted from the unexpected tripping of vacuum circuit breaker on the permanent magnet mechanism column in grid operation,it is considered that the cause is insufficient residual retention margin of each phase of the circuit breaker,that is,the designed permanent magnet mechanism closing retention force is not large enough.Considering that the mechanical characteristics of outdoor pole-mounted circuit breakers may change due to the influence of ambient temperature on neodymium iron boron materials,the main parameter design of pole-mounted vacuum circuit breakers tested in the factory is optimized,appropriate margin is given to meet its environmental requirements.By working experience,the importance of the quality of parts design drawings is emphasized,and solutions are studied to ensure the closing retention force of permanent magnet mechanism,to ensure good mechanical characteristic parameters of circuit breaker,and to improve the operation reliability of permanent magnet mechanism pole-mounted vacuum circuit breaker.关键词
