摘要

输电线路电晕放电不仅会引起巨大的电能损耗

产生可听噪声

而且还会带来一系列电磁干扰问题。因此

导线电晕放电现象一直是设计人员所关心的重要问题。文中基于气体放电理论和数值分析方法

在前人工作的基础上计算不同电离系数和附着系数对导线起晕场强的影响

总结出不同表达式的适用范围并有了新的发现。首先

计算了干燥空气下导线的起晕场强

并将计算结果与Peek公式进行比较

验证了计算模型的正确性。其次

对不同空气湿度下起晕场强的计算结果和试验结果进行了比较

并分析了电离系数和附着系数对潮湿空气中起晕场强的影响。最后

对不同电离系数和附着系数所得计算结果进行了讨论

该讨论结果可为后续电晕放电相关研究提供借鉴。

Abstract

Corona discharge on transmission lines not only causes huge power loss and audible noise

but also brings a series of electromagnetic interference problems.Therefore

conductor corona discharge is always an important problem that designers concerned about.Based on the theory of gas discharge and numerical analysis method

this paper calculates the influence of different ionization coefficients and attachment coefficients on the corona inception field strength of the conductor on the basis of previous work

summarizes the applicable scope of different expressions and makes new findings.Firstly

the corona inception field strength of the conductor under dry air is calculated

and is compared with Peek formula to verify the correctness of the calculation model.Secondly

the results of calculation and experiment data are compared under different air humidity

and the influence of ionization coefficient and attachment coefficient on the corona inception strength in humid air are analyzed.Finally

the calculation results of different ionization coefficient and attachment coefficient are discussed

which can provide reference for further related research on corona discharge.
