Abstract
To satisfy the requirements of controlling and protection of modern power grid, it is necessary to develop the fast switchgear switching to be an executive device. Making full use of the advantages of repulsion and permanent magnetic mechanism, we designed a hybrid fast operating mechanism constructed with electromagnetic repulsion and permanent magnetic mechanism.The switching characteristics of fast mechanism were simulated. The mechanical structures of coil skeleton, shell and T-shaped armature were optimized for the mechanism, and the design to avoid closing bounce was conducted. Thereby, the fast mechanism was developed and the strength of vacuum interrupter was promoted. The prototypes of 12/40.5 kV fast vacuum circuit breaker were assembled and the factory performance debugging was carried out.Furthermore, the technical specifications of manufacture were formulated according to the current standard of circuit breaker, and the technical parameters of devices were provided. Two prototypes have passed the performance verification tests including insulation, machinery, temperature rise, short-time current endurance,and breaking and making ability. All results show that the performance parameters of both prototypes meet the requirements of the technical specifications. For 12 kV prototype, its closing time is no more than 10ms, the opening time is no more than 3 ms and the mechanical life is 5 000. For 40.5 kV prototype, the closing time is no more than 15 ms, the opening time is no more than 5ms, and the mechanical life is 3 000.关键词
