- 摘要:
- 接地是电气安全技术中最重要的技术措施，关系到设备和人身的安全。接地分为工作接地、保护接地、防雷接地、防静电接地等,正确选择接地方式及合理安装非常重要。良好的接地系统在易燃易爆场所能有效减免火灾、爆炸的发生，保证生产安全。塔中Ⅰ号气田油气处理厂位于沙漠地区，土壤电阻率较高，传统接地方法不能达到预期效果，利用外引式接地装置和大型建(构)筑基础群联合接地则效果明显，满足施工及投产运行的需求，对沙漠干旱地区的接地安装方式有一定的参考价值。
Electrical equipment grounding is the most important technical measure of electrical safety technology, it is directly related to equipment and personal safety. Grounding can be divided into working grounding, protective grounding, lightning protection grounding, anti-static grounding and correct selection of grounding method and reasonable installation are very important. A good grounding system in inflammable and explosive places can effectively reduce the possibility of fire and explosion occurrence and ensure safe production. Oil and Gas Treatment Plant in Tazhong I Gas Field is located in desert region, where soil resistivity is high and the traditional grounding method cannot achieve the desired effect. Combined grounding of irfpa type grounding device and large building (structure) group has obvious effect and can meet the demands of construction and production operation, which has a certain reference value in arid desert areas.
