Analysis of the influence of some factors on the contact resistance of bolted busbar connections

Abstract

The paper presents an experimental setup and a method for determining the contact resistance between busbars at a given contact force. Experiments have been conducted by means of an experimental setup, developed for the purpose of studying the influence of the contact force on the contact resistance between busbars with cross-sectional area of 60x6 mm. The study has been performed for two types of bolted connections, complying with DIN 43673, which have been studied for both copper and aluminum busbars.

Innovative Technology for Production of Electrical Cabinets Using Laminated Conductors

“…They were then set out in accordance with the predetermined arrangement, and finally, conductive bolts were used to secure the electrical equipment on the final upper insulation plate. Since it is well known that the contact resistance is dependent on complex physical processes, many of which have a random nature, its analytical computation is subject to significant errors [19]. The presence of contact connections can increase resistance, as well as the heating of the electrical equipment.…”

Double-Sided Self-Pierce Riveting: Electro-Mechanical Analysis of Dissimilar Al-Cu Half-Lap Butt Joints

“…The specimens were subjected to different tests to analyse the mechanical and electrical performance of the mechanical joint. The latter is evaluated by means of the evolution of the electrical resistance with different working temperatures ranging from 16 • C to 100 • C. Comparisons are then made with fastened Al-Cu busbar connections [20,21] to evaluate and discuss the gains resulting from the utilization of DSSPR to produce busbar connections.…”
