摘要
降低山区岩石地质杆塔塔位接地装置的接地电阻值,历来是输电线路建设的难题。三维立体接地装置垂直接地体是一种用传统的水平接地网与垂直接地极相结合构成的三维立体接地装置,可以有效地解决岩石地质塔位接地电阻值过高的问题。
Reducing resistance of pole and tower grounding device in mountain rocky geology is a traditional problem to transmission line construction. Vertical ground system of the 3-D grounding device, which is a combination of traditional horizontal ground grid and vertical ground electrode, can effectively solve the over-valued tower grounding resistance problem in rocky geology.
