摘要
杆塔输电线路在防雷措施方面目前较为普遍的做法是架设避雷线(针)、消雷器等避雷装置并配装线路接地系统,其系统电阻及杆塔接地电阻阻值的测量是线路定期维护的一项重要工作之一。本文针对该系统阻值测量工作中的一些常见误区,就利用电力系统常规工作测试仪器对系统电阻、接触电阻、接地电阻的正确、准确测量方法进行了详细的阐述。
In lightening protection measures, shield wire and eliminator with line ground system, the common method of tower transmission line is to set up and the measurement of system resistance and tower ground resistance is one of the important works for line regular maintenance. Aiming at some common misunderstanding in the measurement of system resistance, this article discusses the correct measurement methods to measure the system resistance, contact resistance and ground resistance by using routine testing instruments.
