Abstract

The embodiment of the invention discloses a mechanical switch closing device of a circuit breaker, which is characterized in that a static contact is fixedly arranged on a shell base of the circuit breaker, a moving contact is arranged on a handle in a linkage manner, the handle is used for driving the moving contact to be in contact with the static contact, a contact pressure spring is used for providing pressure when the moving contact is in contact with the static contact, and a closing lock catch is connected with the handle and can be closed and locked or separated from the handle. The circuit breaker product provided by the embodiment of the invention is compact in structure and realizes reliable closing.

Description

technical field [0001] The embodiment of the present invention relates to the field of circuit breaker technology, and in particular to a mechanical switch closing device for a circuit breaker. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and close, carry and break current under abnormal circuit conditions within a specified time. Motors are protected, and they can automatically cut off the circuit when they are seriously overloaded or short-circuited or under-voltage, so they are widely used in power electronic systems. Ordinary circuit breakers have a purely mechanical structure, and their closing devices have many components, and their reliability is not ideal. In view of this, it is necessary to improve the defects of the existing circuit breaker products to meet the needs of the market. Contents of the invention [0003] The object of the present invention is to provide ...
