Problems solved by technology

When the output power of the circuit board is small, the output force can be increased by increasing the winding turns of the magnetic flux release. In the case of the existing complex trip module, there is often not enough space to place a larger magnetic flux release. Buckle
In addition, the tripping and reset mechanism of the electronic magnetic flux release of the miniature circuit breaker is usually more complicated. When manufacturing, too many parts often bring disadvantages in cost, assembly and reliability.

Abstract

The invention relates to a reset mechanism of a magnetic flux release, belonging to the technical field of small circuit breakers. the release lever and the ejector rod; the release lever is provided with one end that acts with the ejector rod provided with the magnetic flux release device; the release lever is connected with the tripping pin of the circuit breaker; the release lever is released through the quick-release part The lever rotates and acts on the ejector rod of the magnetic flux release to reset the ejector rod. The present invention resets the electronic magnetic flux tripping system through the existing handle, and does not transmit through the main body mechanism, thereby avoiding the influence on the performance of the main body mechanism; using fewer parts to realize the reset function and improving the reliability of product manufacturing. At the same time, the space for reset transmission is freed to increase the number of winding turns of the magnetic flux release, so that the magnetic flux release can have a larger output force; no manual reset is required, which reduces the risk of the reset button being stuck.

Description

technical field [0001] The invention relates to a reset mechanism of a magnetic flux release, belonging to the technical field of small circuit breakers. Background technique [0002] As an important part of power distribution protection, circuit breakers are widely used in the entire power distribution system. At present, small circuit breakers are often equipped with electronic magnetic flux releases. The output of the electronic magnetic flux releases of small circuit breakers is largely determined by the volume of the release and the output of the circuit board. If the output force value of the magnetic flux release is not enough, it cannot directly drive the tripping rod to trip, which affects the reliability of the tripping. The greater the force required to hit the tripping rod for the tripping action and the greater the stroke, the more reliable the tripping action will be. When the output power of the circuit board is small, the output force can be increased by in...
