Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0026] This scheme implements a brand-new temperature-taking device for the busbar of the frame circuit breaker through the designed mechanical structure on the transformer of the frame circuit breaker.

[0027] Fundamental:

[0028] By installing a metal copper shrapnel on the transformer shell, the heat of the busbar is collected into the transformer, and then use the built-in temperature sensor to wrap a layer of heat-conducting silica gel, which is att...

Compared with the prior art, the device has the advantages of accurate temperature measurement, high heat transfer speed and the like.

Description

technical field [0001] The invention relates to the technical fields of low-voltage electrics, product structure and installation, in particular to a busbar temperature-taking device for a frame circuit breaker. Background technique [0002] A frame circuit breaker is a mechanical switching device that can switch on, carry and break current under normal circuit conditions, and can also switch on, carry and break current for a certain period of time under specified abnormal circuit conditions. Universal circuit breakers are used to distribute electric energy and protect circuits and power supply equipment from overload, undervoltage, short circuit, etc. [0003] This kind of circuit breaker generally has a steel frame, and all components are installed in the frame. It has a large capacity, can be equipped with multiple function releases and more auxiliary contacts, and has high segmentation capacity and thermal stability, so it is often used in places requiring high breaking...
