Abstract

The invention provides a tower lightning protection and grounding device, including a conductive connecting rod (3) and a grounding electrode (5) which are vertically arranged. The upper portion of the conductive connecting rod (3) can be electrically connected with a leg of the tower (1). The grounding electrode (5) comprises a coiled segment (51) and a connecting segment (52). The coiled segment (51) can be disposed in a sleeving manner outside a tower base (2) below the ground (4). The coiled segment (51) is electrically connected with the lower portion of the conductive connecting rod (3) through the connecting segment (52). According to the invention, the lower portion of grounding electrode is buried to a similar depth to that of the bottom of the tower base and laid in a plane manner surrounding the bottom of the tower base, so as to avoid secondary excavation in a laying phase, reduce the work amount and construction cost, and improve the tower grounding construction efficiency.

Description

technical field [0001] The invention relates to a lightning protection grounding device for a tower. Background technique [0002] The lightning protection grounding system of towers of overhead transmission lines is very important to the safe and stable operation of the power grid. Therefore, it is necessary to discuss the grounding problems of towers and put forward corresponding improvement measures. Due to the high vertical height of the tower, it needs to bear large horizontal and vertical loads such as wind, ice, wire, broken wire tension or other external forces, so a tower foundation is provided under the tower to stably support the tower and the guide and lightning protection line system . In some mountainous or wild high-voltage transmission towers, a large tower foundation is required to meet the requirements of a stable tower. However, due to harsh construction conditions, it is very difficult to excavate trenches around the tower. At present, the laying of tow...
