土壤模型复杂化对输电线路杆塔接地及耐雷性能的影响
Influence on Power Tower Grounding and Lightning Performance of Power Transmission Line for the Complexity Soil Model
摘要
Abstract
In the traditional design of tower ground engineering of power transmission line ,the soil is simulated as infinite uniform electric soil model ,w hich is different from the actual soil . Therefore ,there would be errors for ground design .Based on Laplace Equation ,the potential func_tion of tower grounding device under the horizontal and vertical two_layer soil model is deduced . As a result ,the corresponding method for grounding resistance calculation is acquired .With the typical ground device of 110 kV Zhongheng power line as an example ,the rules method and the accurate calculation method for layer soil model are adopted ,and then the counterattack trip rates of the typical line are calculated with several of electrical models :the infinite uniform soil ,the hor_izontal and vertical two_layer electric soil .The results show that with an infinite uniform soil for design of grounding device ,counterattack trip rate is lower than those two_layer soil model .关键词
