输电线路杆塔接地电阻测量方法

Transmission Line Tower Grounding Resistance Measurement Method

根据输电线路杆塔接地电阻设备与被测输电线路有无直接电气的连接,可将其划分为接触式测量方法和非接触式测量方法,对其原理进行了翔实介绍。结合接触式测量方法和非接触式测量方法的优缺点,初期的测试可以采用接触式测量方法进行前期输电线路杆塔的接地电阻的布置,使其满足防雷等安全要求,后期对输电线路杆塔进行巡防时,可以采用非接触式测量方法,能较快地发现问题并及时进行防护。定期检测输电线路杆塔的接地电阻也是维护输电线路安全运行的重要保证。

According to the transmission line tower grounding resistance equipment with the measured transmission lines are there any direct electrical connection,it can be divided into contact measurement and non-contact measurement method,has carried on the detailed introduction of its theory.Combining with the advantages and disadvantages of contact measurement and non-contact measurement method,the initial test contact measurement method may be used for the early stage of the transmission line tower grounding resistance of the layout of satisfy the lightning protection security requirements,such as late for transmission line tower guard,can be used in a non-contact method of measurement,can quickly find problems and in a timely manner.Regular testing of transmission line tower grounding resistance is also important to ensure the safe operation of the transmission line maintenance.
