摘要

目前

紫外检测技术在电力系统的应用已受到广泛关注

但其应用方法和标准都处在探索阶段。结合模拟试验方法

研究紫外光子数与增益、距离之间的关系

考虑极不均匀场下的电晕放电

研究光子数与放电强度量化参数（局部放电量、电晕电流）的对应关系。试验结果表明

增益、距离对光子数影响较大

在应用中需选择合适的增益;光子数与距离基本成反比的关系

且在一定程度上能反映出电晕放电强度变化趋势。

Abstract

At present

the application of UV detection technology on power system is being extensively concerned

and its application method and standard are being explored.Based on simulated test

this paper studies on the relationship between the number of UV radiation photons and gain（or distance）

and the corresponding relationship between the number of UV radiation photons and the parameter of quantifying the intensity of corona discharge（partial discharge

corona current） is researched by considering corona discharge of the sever non-uniform electric field.The test results show that gain and distance have a great effect on the number of UV radiation photons

and it is necessary to choose right gain in application;the inverse relationship between the number of UV radiation photons and distance is found

and the number of UV radiation photons can reflect the change of corona discharge level.
