摘要

根据钳表法原理

对输电线路杆塔进行建模及仿真计算

将基于钳表法原理的多基杆塔回路电阻值与单基杆塔理论接地电阻值进行对比

对误差的影响因素及其敏感性进行分析。结果表明:在较低土壤电阻率时避雷线等导体的电阻为造成误差的主要因素

而较高土壤电阻率时杆塔地网与杆塔基础间的互电阻为造成误差的主要因素。

Abstract

Based on clamp meter method

transmission tower model is established and simulated in this paper.The multi-tower loop resistance and theoretical value of tower grounding resistance are compared and the error factor and its sensitivity are analyzed as well.The result indicates that resistance of conductor such as lighting conduct etc.is the major factor which causes the error in lower earth resistivity

and in high earth resistivity the mutual resistance between the tower grounding grids and tower base is the major factor of error.
