摘要

研究输电线路电磁环境影响因素及其防护对策

可以为输电线路的设计提供技术依据

使人们正确认识输电线路电磁环境并合理选择防护对策。笔者首先进行架空输电线路物理模型的建立和电场计算

然后采用电磁分析仪PMM8053B与工频电磁场探头EHP-50C

对焦作500 kV输电线路某段的实际电场强度进行实地测量

通过MATLAB仿真软件验证了理论模型和实验的相符。在此基础上

对影响高压输电线路电场强度的多种因素进行模拟计算

分析指出适当减少相间距以及采用倒三角排列导线可减小输电线路下方的电场强度。

Abstract

Studying the factors that affect electromagnetic environment of transmission line and protective measures can provide technical basis for the design of the transmission line

guide to recognize the electromagnetic environment of transmission lines correctly and select the rational protection measures.First

this article builds up the physical model of overhead transmission lines and calculates the electric field.Then the actual electric field strength of 500 kV transmission line in Jiaozuo city is measured

using PMM8053B electromagnetic analyzer and EHP-50C power frequency electromagnetic field probe.Finally the correctness of the theory and model by the MATLAB simulation software is verified.On this basis

simulated experiments on factors that impact the electric field of high voltage transmission lines are performed

and the design methods and improving measures that can reduce the electric field strength of high voltage power lines in several operation states are concluded.
