一种降低沿海高土壤电阻率地区的接地装置

A Grounding Device for Reducing High Soil Resistivity in Coastal Areas

结合该印尼电厂的实际工程经验,通过查阅相关资料和计算,采用基础内的钢筋混凝土桩作为自然接地体+人工接地体模式在高土壤电阻率地区有一定的适用局限性,故采取利用海水中的钢管桩作为自然接地体,将其与厂区主接地网可靠连接,并能使其接地电阻达到规程要求,对今后的类似工程具有良好的借鉴意义。

Combined with the practical engineering experience of the Indonesian power plant,through consulting the relevant data and calculation,this paper uses the reinforced concrete pile in the foundation as the natural grounding body + artificial grounding body mode,which has certain limitations in the area of high soil resistivity,and uses the steel pipe pile in the sea water as the natural grounding body to connect it with the main grounding grid of the plant reliably and make its grounding resistance stable It can be used for reference for similar projects in the future.
