High-performance electrical engineering distribution circuit breaker

Abstract

The invention belongs to the technical field of electrical engineering, and discloses a high-performance electrical engineering distribution circuit breaker. The high-performance electrical engineering distribution circuit breaker comprises a cabinet body, wherein a plurality of binding posts are arranged on the cabinet body, the plurality of binding posts are each connected with a conductive block, a motor is mounted inside the cabinet body, the motor is connected with a disc, one side of the disc is provided with a cylinder body, the disc is eccentrically hinged with a rocker, the rocker ishinged with a connecting rod horizontally extending into the cylinder body, the cylinder body is internally provided with a first piston fixedly connected with the connecting rod, and the cylinder body is provided with an air outlet; a fixed plate is fixed to the cabinet body, an airbag is arranged on the fixed plate, an air inlet hole is formed in the airbag, and the air inlet hole is connected with the air outlet by means of an air pipe; and an insulating plate is fixed to the cabinet body, a through hole is formed in the insulating plate, an insulating rod penetrates the through hole, the insulating rod is connected with a conductive plate, and the conductive plate is used for conducting the conductive blocks when the airbag jack up the insulating rods due to inflation. The high-performance electrical engineering distribution circuit breaker can solve the problem of difficult heat dissipation inside a circuit breaker when the circuit breaker is working.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, in particular to a high-performance electrical engineering power distribution circuit breaker. Background technique [0002] Circuit breakers are commonly used components in electrical engineering. Existing circuit breakers refer to currents that can close, carry and break currents under normal circuit conditions and can close, carry and break currents under abnormal circuit conditions within a specified time switchgear. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. [0003] Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are se...
