摘要:

为研究螺栓紧固型连接铜母排间接触电阻的主要影响因素,以螺栓连接的矩形铜母排为研究对象,进行了铜母排间接触电阻的理论分析、仿真分析以及实验验证。通过研究表明,接触电阻主要取决于垫圈下方的接触面积和接触压强。在理论分析的基础上,首先利用多物理场耦合有限元分析软件建立了螺栓紧固型连接铜母排的仿真模型;然后,进行不同螺栓预紧力和不同搭接长度下的连接电阻仿真分析;最后,将连接电阻实验结果与仿真结果进行了对比分析,验证了所提结论的正确性。

关键词: 螺栓紧固型连接铜母排, 接触电阻, 搭接面积, 螺栓预紧力

Abstract:

In order to study the main influencing factors of the contact resistance between bolted copper busbars,taking the rectangular copper busbars connected by standard bolts as the research object,the theoretical analysis,simulation analysis and experimental verification of the contact resistance between copper busbars are carried out.The research shows that the contact resistance mainly depends on the contact area and the contact pressure under the washer.Firstly,on the basis of theoretical analysis,the simulation model of bolted rectangular copper busbar is established by using multi physical field coupling finite element analysis software.Furthermore,the simulation analysis of connection resistance under different bolt pretightening force and different lap length is carried out.Finally,the experimental results of connection resistance are compared with the simulation results to verify the correctness of the proposed conclusion.

Key words: bolted copper busbar, contact resistance, lap area, bolt pretightening force
