Problems solved by technology
[0002] The electric tower introduces lightning into the ground through the grounding device to ensure the safe and stable operation of the power line. The grounding resistance of the existing grounding device of the electric tower is large, which cannot ensure that the lightning is quickly guided to the ground, and the grounding device is prone to failure, reducing the safety of the grounding device. Therefore, there is an urgent need to develop a grounding device for electric towers to solve the above problems and facilitate market promotion and application

The invention relates to the technical field of electric tower grounding, and discloses an electric tower grounding device which comprises an upper grounding assembly, a grounding carbon rod and a lower grounding assembly. The upper grounding assembly comprises an upper grounding ring, a plurality of connecting rings and a plurality of first mounting sleeves, the connecting rings are welded to the inner side face of the upper grounding ring and located at the corners of the inner side face of the upper grounding ring, and the first mounting sleeves are fixed to the lower surface of the upper grounding ring; grounding carbon rods are in one-to-one correspondence with the first mounting sleeves, and the top ends of the grounding carbon rods are connected with the first mounting sleeves; and the lower grounding assemblies are in one-to-one correspondence with the grounding carbon rods, and the lower grounding assemblies are installed at the bottom ends of the grounding carbon rods. The upper grounding assembly guides thunder and lightning to the lower grounding assembly through the grounding carbon rod, the grounding resistance between the upper grounding assembly and the lower grounding assembly is reduced, and it is ensured that thunder and lightning current is rapidly led into the ground when thunder damage occurs.
Description
technical field [0001] The invention relates to the technical field of electric tower grounding, in particular to an electric tower grounding device. Background technique [0002] The electric tower introduces lightning into the ground through the grounding device to ensure the safe and stable operation of the power line. The grounding resistance of the existing grounding device of the electric tower is large, which cannot ensure that the lightning is quickly guided to the ground, and the grounding device is prone to failure, reducing the safety of the grounding device. Therefore, there is an urgent need to develop a grounding device for electric towers to solve the above problems, and to facilitate market promotion and application. Contents of the invention [0003] The technical problem to be solved by the invention is: the grounding resistance of the existing electric tower grounding device is relatively large. [0004] In order to solve the above technical problems, t...
