摘　　要：为在电力变压器的局部放电检测和定位中利用X射线的激励作用,对X射线辐照条件下,油中固体介质内气隙放电以及油中放电进行了模拟试验,研究表明X射线可降低局部放电起始电压增加放电强度。The partial discharge (PD) detection of pwoer transformers is often concerned. The influence of X ray irradiation on PD is used to the location of PD. It is meaning to develop the research on the influence of X ray irradiation on PD. This paper discusses the principles of cavity discharge solid dielectric in transformer oil and the partial discharge of transformer oil. It provides some useful conclusions.
