Method for Estimating the Initial Welding Current of Closed High-Current Contacts under Pulsed Heating
摘要
Abstract
A study of the softening process of contact spots of closed high-current copper contacts caused by recrystallization of the material during short-circuit shock currents has been carried out. An original method has been developed for calculating the magnitude of the pulse current, which initiates the welding of contacts, which does not require preliminary experimental measurements.
