Abstract (en)
A static contact support (12) for a circuit breaker, comprising a base layer (122) and a reinforcing layer (124). The base layer is made of a material with good heat-conducting and electricity-conducting properties. The reinforcing layer is superposed on the base layer, and made of a material with good mechanical strength and magnetic permeability. The base layer has good electricity-conducting and heat-conducting properties, so on the one hand, produces very little heat; on the other hand, the base layer enables the static contact support to cool the arc, helping to extinguish it. The reinforcing layer on the one hand can reinforce the mechanical strength of the base layer; on the other hand, the magnetically permeable reinforcing layer can channel the arc into an arc extinguishing mechanism of the circuit breaker, so it is extinguished quickly. Furthermore, being superposed, the base layer and reinforcing layer can be conveniently fitted into the circuit breaker.
