Description

Main circuit is adaptor along separate routes

The utility model relates to the circuit connecting mechanism in a kind of switchgear, and especially relevant main circuit is the switching part of usefulness along separate routes.

In draw out switchgear, the electric energy that main circuit shunt adaptor is used for accepting is divided into two-way and supplies with 1/2 functional unit.In the prior art, the inlet wire main contact with along separate routes between the inlet wire fixed contact and along separate routes all adopt soft insulated conductor to be connected between outlet fixed contact and the cable connecting terminal, connected mode is the fastening crimping of usefulness compressing piece.The shortcoming of this connected mode big, the temperature rise of ubiquity caloric value in use, the variations in temperature in the time of also can be owing to long-term switching electricity makes compressing piece and flexible conductor take place to become flexible, thereby easily causes electric fault.

The purpose of this utility model is to provide a kind of temperature rise low, is difficult for producing the main circuit shunt adaptor of electric fault.

In order to achieve the above object, main circuit of the present utility model adaptor along separate routes has mounting panel, and inlet wire main contact, shunt inlet wire fixed contact, shunt outlet fixed contact and cable connecting terminal are housed on the mounting panel, also have 3 shunt inlet wire copper bus-bars and 6 shunt outlet copper bus-bars or have 4 inlet wire copper bus-bars and 8 shunt outlet copper bus-bars along separate routes; Inlet wire main contact and shunt inlet wire copper bus-bar rivet; Shunt inlet wire fixed contact and shunt inlet wire copper bus-bar are with rivet or make one; Along separate routes outlet fixed contact and cable connecting terminal respectively with shunt outlet copper bus-bar with rivet or make one.

After adopting such structure, owing to substituted soft insulated conductor with shunt inlet wire copper bus-bar and shunt outlet copper bus-bar, make current density less, the copper bus-bar caloric value is little; Also because inlet wire main contact and shunt inlet wire copper bus-bar rivet, along separate routes between inlet wire fixed contact and the shunt inlet wire copper bus-bar, and all adopt rivet or make one between shunt outlet fixed contact and cable connecting terminal and the shunt outlet copper bus-bar, this connected mode is fastenedly connected than crimping that mode is tight, the gap is little, thereby reduced caloric value, temperature rise is low, and rivet is difficult for loosening simultaneously, be difficult for producing electric fault, functional reliability height.In addition, structure is also simple, is convenient to make.

Below in conjunction with drawings and Examples the utility model is described in further detail.
