Abstract

The invention discloses a lightning wire anti-thunder capacitance-eliminating grounding device, and belongs to the technical field of power system power transmission. The device comprises lightning wire isolators on the two sides of a pole tower, the two lightning wire isolators divide a lightning wire into a middle lightning wire section and two side lightning wire sections, each lightning wire isolator comprises an insulating support, one end of the insulating support of each lightning wire isolator is connected with the side lightning wire section on the corresponding side, the other end of the insulating support of each lightning wire isolator is connected with the pole tower through the middle lightning wire section, the inside of each insulating support is provided with a non-linear resistance element, the two ends of each non-linear resistance element are connected with conductive elements, the conductive elements close to the pole tower are connected with a down lead, the down lead is connected with the grounding device, and the conductive elements away from the pole tower are connected with the side lightning wire sections on the corresponding sides through first wires. According to the lightning wire anti-thunder capacitance-eliminating grounding device, distributed capacitance between the wires and the ground can be effectively reduced and a power grid can keep stable.

Description

technical field [0001] The invention belongs to the technical field of electric power system transmission, and in particular relates to a grounding device for lightning protection and capacitor elimination of a lightning protection line. Background technique [0002] Lightning conductor (also known as overhead ground wire) is one of the facilities to protect power transmission lines from lightning strikes. It is used for lightning protection. It is erected on the top of the power transmission line tower and set above the power transmission wire. Use the tower body of the iron tower and the steel bars in the concrete pole or the special climbing ladder for the pole, the grounding down conductor, etc. to connect the down conductor to the grounding device (ground grid). According to current standards, my country's regulations stipulate that lines above 110kV should generally be equipped with lightning protection lines throughout the line. In order to ensure the safety of line ...
