Abstract

This paper is focused on hybrid busbar joints with a twofold objective of understanding the differences in electrical resistance under service conditions and evaluating their performance when subjected to hazardous high voltages. Three different types of joints fabricated by conventional bolting, friction stir spot welding and injection lap riveting are selected and two different experimental setups are used to allow the hybrid busbars to be tested up to high voltage electrical discharges of 30 kV. The work is an enhancement of previous experimental and numerical investigations of the authors in the field with results showing no signs of damage or catastrophic failure when the different types of busbars are subjected to high voltage electrical discharges. Results also confirm the good overall performance and advantages of injection lap riveted hybrid busbar joints against bolted and friction stir spot welded.

混合母线接头在使用和高压条件下的电气性能

本文的重点是混合母线接头，目的有两个：一是了解使用条件下的电阻差异，二是评估其在危险高压下的性能。本文选择了通过传统螺栓连接、搅拌摩擦点焊和注射搭接铆接制造的三种不同类型的接头，并使用了两种不同的实验装置，以便对混合母线进行高达 30 kV 的高压放电测试。这项工作加强了作者之前在该领域进行的实验和数值研究，结果表明不同类型的母线在承受高压放电时没有损坏或灾难性失效的迹象。研究结果还证实，与螺栓连接和搅拌摩擦点焊相比，注射搭接铆接混合母线接头具有良好的综合性能和优势。
