Abstract

The invention discloses an electrical engineering power distribution circuit breaker and particularly relates to the field of circuit breakers. The electrical engineering power distribution circuit breaker includes a casing. The casing is provided therein with a main circuit cavity and two branch circuit cavities. The two branch circuit cavities are arranged symmetrical about the main circuit cavity. The two branch circuit cavities are integrated with the main circuit cavity. An arc extinguishing chamber is disposed on the bottom of the main circuit cavity. An overcurrent tripper is disposed on one side of the arc extinguishing chamber, and an overheat bimetal piece is disposed on the other side of the arc extinguishing chamber. The electrical engineering power distribution circuit breakeruses an upper shield, a porcelain plate, and a corrugated tube to suppress the extinguished arc, and does not cause re-ignition of the arc, thereby ensuring the effectiveness of arc extinguishing. Amovable conductive rod and a fixed conductive rod each consists of an inner guide tube and multiple outer guide rods to form an enlarged-diameter wire. On the premise of ensuring the diameter of a conductor required by corona, the cross-sectional area of the conductor is reduced so as to reduce the electric field strength and corona discharge on the surface of the conductor, reduce noise, and reduce interference on radio, thereby improving the electromagnetic shielding effect.

Description

technical field [0001] The present invention relates to the field of circuit breakers, and more specifically, the present invention relates to a circuit breaker for electrical engineering power distribution. Background technique [0002] A circuit breaker is 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 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 severely overloaded, short-circuited, or under-voltage. Its function is equ...
