Abstract
The utility model belongs to the high voltage electrical equipment field and especially relates to a three-position isolation circuit breaker. The three-position isolation circuit breaker comprises an isolation switch. A lower portion of the isolation switch is connected with an epoxy installing plate. A lower portion of the epoxy installing plate is provided with a vacuum circuit breaker arc extinguishing chamber. The vacuum circuit breaker arc extinguishing chamber is connected with the isolation switch. The epoxy installing plate is downwardly extended so as to form an installation support. The installation support is provided with a rotatable insulation pressing plate. One end of the insulation pressing plate is connected with one end of the vacuum circuit breaker arc extinguishing chamber. The other end of the insulation pressing plate is provided with an adjusting apparatus. The installation support is also provided with an outgoing line copper bar which is connected with one end of the vacuum circuit breaker. According to the circuit breaker of the utility model, the isolation switch and the vacuum circuit breaker arc extinguishing chamber are arranged integratedly; the size of the whole three-position isolation circuit breaker is effectively reduced so that a size of a whole switch cabinet is reduced too; cost is saved.
