为研究电晕笼与输电线路导线电晕损失的等效性问题，对不同布置结构的导线电晕损失进行试验研究。通过电晕笼与试验线段两种试验结构布置，分别对不锈钢管模拟的光滑导线，直径22．28mm，以及LGJ-300／50导线，直径24．26mm，进行电晕损失测量试验。采用考虑电容因素的修正公式计算等效系数，对试验结果进行等效验证。获得了光滑导线、单根钢芯铝绞线的场强一致方法等效与修正系数方法等效的对比结果。在场强一致条件下，导线电容越大，产生的电晕损失也随之增大。考虑导线电容的影响可以减小等效误差。分析认为，等效修正方法可以较好地应用于电晕笼结构和线段结构之间的导线电晕损失等效。今后可对空间电荷对于电容的影响开展进一步研究，从而可以获得更为准确的电晕损失等效修正系数。本文研究成果对于线路电晕损失估算具有一定的实际应用价值。

In order to research corona effect equivalence of corona cage and transmission line conductor, corona losses of different structure conductors were tested. Corona cage and test line structural arrangement were adopted to test corona loss of smooth conductor, which was simulated by stainless steel tube （diameter 22.28 mm） and LGJ-300/50 （ diameter 24.26 mm）. Considering capacitance, a modifier formula was used to test equivalence results. The equivalence contrast results of smooth conductor and single aluminum cable steel conductor by electric field conformity method equivalence and compensation factor were obtained. In the condition of the same electric field strength, the corona loss increase with increasing conductor capacitance. Taking conductor capacitance into account, the equivalence error would be less. The analysis shows that the equivalent correction method can be applied to conductor corona loss equivalence of corona cage and test line conductor. The research results have a certain practical value for transmission line corona loss estimation.
