Abstract

When the transformer has a short-circuit fault, the electromagnetic force may damage the winding. Especially, the mechanical strength of the winding at high temperature is worse than that at normal atmospheric temperature. The common transformer short-circuit test object is the retired real transformer. The experiment cost is high, and it is difficult to compare the effects of different factors. In this paper, we designed a transformer winding short-circuit experimental model suitable for high temperature environment. The model is applicable to epoxy-bonded continuously transposed conductors (CTCs) with different wire gauges. The model can further improve the research efficiency of short-circuit test.
