Stress Relaxation in Copper Bolted Busbar Assemblies with New Design Concept of the Bolt Holes

摘要

W artykule opisano badania eksperymentalne, dotycz?ce napr??eń w zespole miedzianych szyn zasilaj?cych o po??czeniach ?rubowych. Zastosowano now? propozycj? otworów ?rubowych, które, po porównaniu z klasycznymi metodami, wykaza?y mniejszy spadek si?y docisku, co przek?ada si? na zwi?kszon? niezawodno?? po??czenia.%This article reports experimental investigation results of the stress relaxation in copper bolted busbar assemblies with new design concept of the bolt holes (S-design and G-design). The results of the new case are compared with the results of the classical case of the same assemblies and it is observed that for the new S- and G- designs the decrease in the fastening force is quite low which stands for a higher level of reliable assembly operation.
