摘要
原油储油罐防止直击雷措施主要采用直接接地方式,防雷接地电阻是接地系统中的一项重要指标。由于受土壤等环境腐蚀影响,随着运行时间的延长,接地装置不可避免的存在腐蚀,阻值受到影响,影响油田设施的安全运行。接地电阻值是否满足要求是防止油田生产设施免受雷击自然灾害的有效手段,直接影响油田的安全生产。在测量中,影响仪器精度与准度的因素很多,如果对地网接地电阻测试不准确,也可能产生重大安全生产事故,因此如何正确测量接地电阻,确保接地系统有效接地,对油田生产意义重大。
Direct grounding method is mainly adopted as preventive measure for direct lightning in crude oil storage tanks. Lightning protection grounding resistance is an important indicator of the grounding system. Due to the effects of soil environment corrosion and so forth,corrosion of grounding device exists inevitably with the extension of running time. Then the resistance is affected,which affects the safe operation of oilfield facilities.Whether the grounding resistance value meets the requirements or not is effective means to prevent the oilfield production facilities from lightning strike and such natural disasters directly affect the safe production of oilfield. In measuring,there are many factors influencing the precision and accuracy of the instrument. If the ground wire resistance test is not accurate,it may also result in major safety accidents. Therefore,how to correctly measure the grounding resistance to ensure the effective grounding system is of great significance to oilfield production.
