“…The closing drive and closing hold functions of the electromagnetic drive can be realized by one coil or by two coils separately. As the closing drive force is as high as several thousand N, the closing coil needs a large number of excitation turns, and at the same time, it needs a large closing power, which requires a large current and small resistance of the driving coil [5]. In the process of closing and holding, the locomotive requires a smaller closing current to reduce line electromagnetic interference and coil heating, then the closing coil resistance is larger.…”

The vacuum circuit breaker is the main switch of electric locomotive, controlling the on and off of the main circuit of electric locomotive. Existing vacuum circuit breaker of electric locomotives generally the air-driven, electromagnetic retention, this vacuum circuit breaker structure is simple and stable performance is high, but large mass, high air tightness requirements, the shortcomings of the noise. The design of this design according to the actual situation of electric locomotives, the design of a vacuum circuit breaker does not require compressed air drive, electronic control of mechanical manipulation mode of the circuit breaker, the new vacuum circuit breaker using electromagnet drive device to realize the vacuum circuit breaker opening and closing operation, while increasing the energy storage device for the vacuum circuit breaker closing operation to provide the necessary energy. This new type of electromagnetic vacuum circuit breaker has the characteristics of small size, simple structure, low cost and high reliability performance.
