油气管道交流排流用接地极接地电阻取值及计算
Selection for Insulating Device Protector for Cathodic Protection in Oil and Gas Pipeline Project
摘 要
目前国内外关于交流排流的标准规范及文献中均没有关于交流干扰用接地极接地电阻如何确定及计算的相关规定, 以至于在实际工程应用中对于接地极参数选取无统一的原则。根据这种情况, 以实际工程中常用的裸铜线接地极为例, 参照相关部门的规范选取关于排流接地极接地电阻的计算公式, 并提出了用于交流排流及屏蔽保护的接地极的工频接地电阻和冲击接地电阻的数值要求。

Abstract
The related parameters, such as earthing resistance and calculation formula, which used for AC mitigation and AC fault shield, are not mentioned in related codes or standards. As a result of these, uniform principles for determining the parameters of earthing in real projects. So, bare copper wire are selected for calculation of earthing resistance. The formula for calculation earthing resistance are referenced from relation related codes or standards. At the same time, numerical range for power frequency earthing resistance and impulse earthing resistance are determined.
