摘 要：在絕緣子串表面直接測量電場強度時，電場測量探頭靠近絕緣子串引起其表面電場畸變。提出了一種通過測量紫外輻射數(shù)值間接獲得絕緣子串表面電場的方法。分析了表面電場與紫外輻射之間的數(shù)值關系，采用有限元電磁場仿真ANSYS軟件對XP-100懸式絕緣子串表面的電場進行仿真，得到絕緣子串周圍的電場分布，并依據(jù)它們的數(shù)值關系推導出紫外輻射場分布，對紫外輻射場分布和電場分布進行對比分析。結果表明：紫外輻射場分布和電場分布保持相同的變化規(guī)律，即可通過測量紫外輻射值間接獲得絕緣子串表面電場強度，驗證了該方法的可行性。

Abstract: When the electric field intensity is measured directly on the surface of insulator string, the electric field distortion is caused by the electric field measuring probe near the insulator string. This paper proposed a kind of method to indirectly obtaining the surface electric field of insulator string by measuring the ultraviolet radiation value. Analysis was made to the numerical relationship between the surface electric field and ultraviolet radiation. The electromagnetic finite element simulation software of ANSYS was used to simulate the surface electric field of XP-100 suspension insulator string to get the distribution of the electric field around the insulator string. According to their numerical relationship, the distribution of ultraviolet radiation field was derived. The distribution of ultraviolet radiation field and electric field distribution were compared and analyzed. The results show that the distribution of ultraviolet radiation field and the distribution of electric field keep the same law, and the surface electric field of the insulator string can be indirectly obtained by measuring the ultraviolet radiation value, thus proving the feasibility of the method.
