Abstract

The utility model provides a quick response 10 kV circuit breaker, relates to the circuit electrician technical field, and comprises a device seat and a quick response circuit breaking mechanism, the upper side of the device seat is provided with the quick response circuit breaking mechanism, the inner side of the device seat is provided with an electricity dredging assembly, and through the arrangement of the quick response circuit breaking mechanism, when the device needs to be used, the quick response circuit breaking mechanism is arranged on the inner side of the device seat. Through the cooperation of the electrifying rotating shaft in front of the electrifying pole and the electrifying plate, normal electrifying can be realized under normal conditions, and the electrifying plate is directly lifted through the electrifying rotating shaft under abnormal conditions, so that when a circuit problem occurs, the electrifying plate can be directly and quickly cut off to achieve a quick power-off effect, and in a normal closed state, the electrifying plate can be directly and quickly lifted up through the electrifying rotating shaft to achieve a quick power-off effect. By connecting with the electrifying plate, current can normally pass through effectively, and in a non-closed state, the circuit can be directly interrupted through the electrifying groove without influencing subsequent use, and in the subsequent continuous use, the circuit can be normally used only by reconnecting without causing subsequent influence.
