Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] refer to figure 1 , is a multifunctional circuit breaker disclosed in the present invention, comprising a circuit breaker body 1 , and a casing 2 is sheathed on the outside of the circuit breaker body 1 . In this embodiment, the housing 2 separates the circuit breaker body 1 from the outside, and the housing 2 is a hollow structure, and the material of the housing 2 is specifically a hard insulating material.

[0031] The sidewall of the housing 2 is provided with cooling holes 21 . In this embodiment, the hot air generated by the circuit breaker body 1 can be discharged through the heat dissipation holes 21. There are several heat dissipation holes 21, and the several heat dissipation holes 21 are evenly distributed on the casing 2. The heat dissipation effect of the plurality of heat dissipation holes 21 is better. .

[0032] Four baffles 22 are a...

Abstract

The invention relates to a multifunctional circuit breaker. The multifunctional circuit breaker comprises a circuit breaker body; a shell is arranged on the outer side of the circuit breaker body in asleeving mode; four baffles are arranged on the top of the inner wall of the shell; a groove with a downward opening is defined by the four baffles; a groove opening of the groove is connected with amicro-motor through a supporting rod; an output shaft of the micro-motor is rotationally connected with a fan; a switch contact piece is arranged at one end, away from the fan, of the micro-motor; aconnecting rod which is hinged to the groove is arranged in the groove in a penetrating mode; a copper contact piece matched with the switch contact piece is connected to the hinged position; a temperature sensor, a PLC, a vertical sliding rod and a driving mechanism for driving the vertical sliding rod to move are symmetrically arranged in the shell; the PLC is connected with the temperature sensor and the driving mechanism; an output shaft of the driving mechanism is connected with the sliding rod; a first sliding chute and a second sliding chute are symmetrically formed in the upper side and the lower side of the shell; a transverse rod is transversely arranged on the sliding rod; and the end part, close to the groove, of the transverse rod is connected with the end part of the connecting rod. The multifunctional circuit breaker has a heat dissipation effect and can achieve a warning effect.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a multifunctional 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 achieve the closing effect, and carry and break current under abnormal circuit conditions within a specified time. 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 equivalent to a fuse-type switch. Combination with overheating and underheating relays, etc. The circuit breaker in the prior art will generate heat after being used for a period of time. [0003] The above-mentioned prior art solution has the following defects: when the circuit breaker generates heat, the circuit devic...
