摘要
爆破接地技术是近年发展起来的降低接地装置接地电阻的新技术，通过爆破制裂，再用压力机将低电阻率材料压入爆破裂隙中，从而起到改善很大范围的土壤导电性能的目的，相当于大范围的土壤改性。采用这种技术对广东２２０ｋＶ韶郭线３００号杆塔的接地装置进行了改造，将接地电阻从２７０Ω降到１０４Ω，提高了供电可靠性。
The explosion grounding technology is newly developed to decrease grounding resistance of transmission tower. By this method the low resistivity materials are pressed into the explosion cracks, by which the conductive characteristics of the soils are improved in a large area. As the result, the grounding resistance of a 220 kV transmission tower was decreased from 270 Ω to 10 4 Ω.
