Abstract

The invention discloses a circuit breaker with good current blocking performance. The circuit breaker comprises an interrupter shell and a handle, one end of the handle penetrates through the interrupter shell and extends into the interrupter shell; a connecting shaft is fixedly connected to one side of the inner wall of the interrupter shell, a driving disc is rotatably connected to an outer surface of the connecting shaft, one end of the handle is fixedly connected with an outer surface of the driving disc, and a driving mechanism is rotatably connected to a front face of the driving disc through a short rod. The invention relates to the technical field of circuit breakers, according to the circuit breaker with good current blocking performance, a first conductive sleeve and a first conductive sheet are arranged on the surface of an upper guide pillar; by utilizing the first conductive sleeve and the first conductive sheet on the surface of the upper guide pillar, when a connecting pillar is positioned between the upper guide pillar and a lower guide pillar, the first conductive sleeve and the second conductive sleeve can be respectively contacted with the connecting pillar and the lower guide pillar, and when the connecting pillar is not positioned between the upper guide pillar and the lower guide pillar, a flow choking effect is achieved, so that the structure is simple and the circuit breaker is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker with good flow blocking performance. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy. Start the asynchronous motor frequently, protect the power line and the motor, and automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to the combination of a fuse switch and an overheating relay. In the generation, transmission and use of electricity, power distribution is an extremely important link. The power distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit...
