Abstract

The invention relates to an interlocking mechanism, electric control equipment with the interlocking mechanism and a circuit breaker with the interlocking mechanism. The fixed end of a bimetallic strip of the interlocking mechanism and a moving contact assembly are connected and provided with an adjusting structure, the relative position between the free end of the bimetallic strip and a driving arm of a lock catch assembly is changed through the adjusting structure, therefore, the position of the bimetallic strip becomes adjustable, and then the technical problems that in the prior art, the production efficiency and the product yield are low due to the fact that the bimetallic strip cannot be adjusted are solved.

Description

technical field

[0001] The present invention relates to the general technical field of circuit equipment, and more specifically, the present invention relates to a control wire or switch, an interlock mechanism for protecting personnel or equipment, electric control equipment and a circuit breaker equipped with the interlock mechanism. Background technique

[0002] The circuit breaker for line protection includes two terminals connected to the line, and a disconnectable circuit is arranged between the two terminals; the disconnectable circuit includes a moving contact, a static contact, and a switch for controlling the position of the moving contact. The interlock mechanism also includes a thermally sensitive disconnected bimetal for protecting the circuit from overload and an electromagnetic disconnecting part containing a coil; the coil of the electromagnetic disconnecting part has a plunger-type iron core connected to the push rod, which is When the line is short-circuite...
