【摘要】 通过对芹山水电站接地网的改造实践,证明采用深孔分层压力灌注接地网新技术,对降低高土壤电阻率、改善地区接地网的接地电阻是极为有效的。利用该法改造的接地网,具有接地电阻小、散流能力强、不受地网敷设范围的限制、接地电阻稳定、节省资金、安全可靠等优点,可在很多场合特别是类似水电站推广应用。更多还原

【Abstract】 The practice of the rehabilitation of the earthing network for the Qinshan Hydropower Station showed that the adoption of deep pressure grouting technology for earthing network is very effective to decrease the soil resistance ratio and to improve the earthing resistance of the local earthing network. Using such technology to rehabilitate earthing network has the advantages of low earthing resistance, strong scatteredcurrent capacity, stable earthing resistance, financial saving, safety and reliability. It can be popularized to similar hydropower stations.更多还原
