A push-type low-voltage miniature circuit breaker assembly

Abstract

The invention discloses a pushing type low-voltage micro-breaker component which comprises a bidirectional wire connector, a breaker protecting rack, a pushing pull type switch, a vacuum arc-extinguishing chamber, a static contactor and a base frame, wherein the bidirectional wire connector is fixedly connected with one end of the breaker protecting rack; a current terminal is arranged at the top end of the bidirectional wire connector; a joint is arranged at the bottom end of the bidirectional wire connector; the current terminal is fixedly connected with the static contactor at the lower end; the bidirectional wire connector is moveably connected with the pushing pull type switch at one end; an insulating pushing handle is arranged at one end of the pushing pull type switch; the pushing pull type switch is fixedly connected with a driving system at the bottom end in the breaker protecting rack through a driving rod at the bottom end; the driving system is fixedly connected with an inner base end of the breaker protecting rack through a fixing bracket on one side; the vacuum arc-extinguishing chamber is fixedly mounted above the driving system. The pushing type low-voltage micro-breaker component has a simple structure, can be widely applied and can protect the circuit in real time.

Description

technical field [0001] The invention relates to the technical field of circuit breaker equipment, in particular to a push-type low-voltage miniature circuit breaker assembly. 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 are divided into For high-voltage circuit breakers and low-voltage circuit breakers, the division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. [0003] When the conventional low-voltage circuit breaker is disconnected due to a fault, it cannot be manually reset, and the circuit breaker needs to be replaced again, and the power consumption is large, the service life is short, the arc leakage leads to the occurrence of safety accidents, and the insulation level i...
