Abstract

An incoming line copper bar connecting method comprises a breaker body. The breaker body is installed on a base, incoming line copper bars are fixed onto the breaker body, the incoming line copper bars are embedded into the front side of an upper opening of the breaker body, the lower ends of the incoming line copper bars are fixed through an incoming line bolt set, and the incoming line bolt set is embedded into the breaker body. The incoming line copper bar connecting method is safe and reliable, maintenance is convenient, and potential electrical safety hazards are avoided.

Description

technical field [0001] The invention relates to a connection mode of copper bars, in particular to a connection mode of copper bars for incoming lines of a low-voltage drawer cabinet. Background technique [0002] The overlapping and fixing of copper bars must first meet the current carrying capacity requirements (the size of the copper bars should be selected reasonably), and second, the overlapping surface must meet the requirements of the standard (the overlapping surface must meet the requirements of the overlapping area, That is to say, the selection of the bolt group should be reasonable to ensure the unit pressure), and the third is to ensure that the overlapping and fixing structure of the copper bar is reasonable to meet the installation strength requirements for dynamic and thermal stability. If the configuration process structure of copper bars is complicated and unreasonable, it will cause waste of copper bars, and at the same time, the support insulation parts m...
