A study of contact resistance model for the busbar joints lubricated by contact aid compounds

Based on previous studies about the contact resistance model and the conductive paste, the contact resistance model for the busbar joints lubricated by contact aid compounds is formed. The relation between the contact aid compound´s technical parameters and the contact spot´s microscopic parameters is established. Using this model, the numerical calculation and analysis of the contact spot´s microscopic parameters and the electrical contact properties are made, and some results are obtained. The computer simulation of the electrical contact phenomena is realized initially under lubricated and un-lubricated case.
