Abstract

A conductive system is used for thermal tripping of a circuit breaker, the conductive system comprises a heating element and a bimetallic strip, the heating element and the bimetallic strip are connected through a rivet, the heating element comprises a left electric connecting piece, a bending part and a right electric connecting piece, the left electric connecting piece is connected with a moving contact through a flexible electric wire, and the bending part is connected with the right electric connecting piece through a flexible electric wire. The left electric connecting sheet and the right electric connecting sheet are electrically connected with a circuit breaker loop conductor; a first buffer silica gel sheet is arranged at the contact position of the rivet and the heating element, and a second buffer silica gel sheet is arranged at the contact position of the rivet and the bimetallic strip.

Description

technical field [0001] The invention relates to a conductive system. Background technique [0002] The circuit breaker is an important protection device in the low-voltage power distribution system. It provides functions such as short-circuit protection, overload protection, and under-voltage protection for AC grid lines and electrical equipment. The conventional conductive system means that when the line is overloaded, the current passing through the low-voltage circuit breaker is greater than the rated current specified by the low-voltage circuit breaker, the heat generation of the low-voltage circuit breaker increases, and the thermal tripping device is driven to trip the low-voltage circuit breaker. Overload protection for lines and electrical equipment. [0003] The shortcomings of the existing conductive system are: the large number of parts is not conducive to assembly; the double gold sheet is welded and fixed to the heating element, and once the welding quality req...
