Maintenance-free heat dissipation type intelligent circuit breaker

Abstract

The invention discloses a maintenance-free heat dissipation type intelligent circuit breaker. The intelligent circuit breaker comprises a box body, a front door, an air inlet control mechanism and anair outlet control mechanism. Two partition plates are installed between the inner walls of the box body in parallel; an air inlet fan is mounted on the partition plate on the left side; an air outletfan is mounted on the partition plate on the right side; a concentric-square-shaped plate is mounted between the two partition plates; a mounting base is mounted at the bottom end of the concentric-square-shaped plate; punching screen plates are installed on the side faces of the box body; a circuit breaker body is fixedly installed on the mounting base; an air inlet is formed in the left end ofthe box body; an air outlet is formed in the right end of the box body; a temperature and humidity sensor is installed on the inner wall of the box body; a wire penetrating base is installed at the top end of the box body; and a wire hole is formed in the top end of the wire penetrating base. The front door is fixed to the front side face of the box body through screws, and a sealing plate is hinged to the front side face of the front door. The circuit breaker is good in anti-collision and anti-extrusion performance and high in safety, and is provided with a heat dissipation mechanism.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a maintenance-free heat dissipation intelligent circuit breaker. 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. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they It can automatically cut off the circuit in the event of serious overload, short circuit and undervoltage. Its function is equivalent to the combination of a fuse switch and an ove...

[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. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they It can automatically cut off the circuit in the event of serious overload, short circuit and undervoltage. Its function is equivalent to the combination of fuse switch and overheating and underheating relay. There are many occasions for using circuit breakers, and its safety has always been a hot spot of concern. , the traditional circuit breaker will heat up after a period of use, and it is very inconvenient for the staff to clean the dust and maintain it. And because of its simple structure, lack of heat dissipation mechanism and protection mechanism, long-term use is easy to damage the circuit and cause safety hazards. Accidents, when accidentally bumped and squeezed will also damage the circuit breaker and cause economic losses
