Problems solved by technology

[0004] The technical problem to be solved in the present invention is to provide a control device for a small circuit breaker in an explosion-proof distribution box. One of the purposes is to solve the problem that some relay control devices cannot self-lock the switch after the switch is activated, and the usability is relatively low. In addition, there are some relay control devices where dust is easy to enter the wiring hole, which makes the connection effect poor, and the fixing effect on the connecting wire is poor, and the connecting wire is easy to loose, causing a short circuit and causing damage to the device. question

Abstract

The invention discloses a control device for a miniature circuit breaker of an explosion-proof distribution box, and belongs to the technical field of explosion-proof electrical equipment. The control device comprises a main body, a pushing element is arranged at the left end of the main body, an emergency stop button is fixedly connected with the front face of the main body, a locking element is arranged at the left end of the pushing element, the back face of the locking element is fixedly connected with the front face of the main body, and a mounting hole is formed in the lower end of the main body. Through combination of the locking element and the pushing element, after a relay is started, the pushing element of the relay is conveniently locked, the phenomenon of misoperation is avoided, and therefore serious consequences are avoided, the fixing element slides along the locking element through the arrangement of a sliding groove, the pushing element is clamped through a clamping groove, and thus the movement of the pushing element is limited; and in addition, a telescopic fixing rod and a first damping element are arranged, the limiting effect on the fixing element can be achieved, and the fixing element is prevented from sliding excessively.

Description

technical field [0001] The invention relates to the technical field of explosion-proof electrical equipment, in particular to a control device for a small circuit breaker of an explosion-proof distribution box. 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 faults. Its function is equivalent...
