Embodiment Construction

[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0041] like Figure 1 to Figure 5 As shown in common, a lightning protection line lightning protection and capacitor elimination grounding device includes lightning protection line isolators 2 arranged on both sides of a tower 1. The two lightning protection line isolators 2 divide the lightning protection line 3 into a middle lightning protection line 31 and two sections far away from the tower. The side lightning protection wire 32 of 1; the lightning protection wire isolator 2 includes an insulating support 21, one end of the insulating support 21 is connected to the side lightning prot...

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 power system power transmission, and in particular relates to a grounding device for lightning protection and capacitor elimination of lightning protection lines. Background technique [0002] The lightning protection line (also called overhead ground wire) is one of the facilities to protect the transmission line from lightning strikes. It is used for lightning protection. It is erected on the top of the transmission line tower and above the 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 with the grounding device (ground grid). According to the current standard, my country's regulations stipulate that lines above 110kV should generally be equipped with lightning protection lines across the board. In order to ensure the safety of line transmission and avoid lightning...
