Wind power plant or photovoltaic power station equipment grounding device

Abstract

The invention discloses a wind power plant or photovoltaic power station equipment grounding device, the device comprises an overhead lead-in wire and a lightning arrester which are arranged on one side of a wind power plant or a photovoltaic power station, the overhead lead-in wire is connected with a grounding lead through the lightning arrester, and the other end of the grounding lead extends into the ground to be connected with a charge guide column. The charge guide column is fixed on the inner side wall of the conductive water tank, the conductive water tank is arranged underground, a conductive graphite mounting frame is arranged under the bottom of the conductive water tank, and the conductive column penetrates through the conductive water tank and the conductive graphite mounting frame and then extends into soil. The device is good in conductivity, rapid discharge of charges can be achieved, and after the conductive columns are corroded, replacement is convenient.

Description

technical field [0001] The invention relates to a grounding device for wind farm or photovoltaic power station equipment, belonging to the technical field of grounding equipment. Background technique [0002] The traditional wind farm or photovoltaic power station grounding device refers to the general term for the grounding electrode buried in the ground and the connecting wire between the grounding electrode and the equipment. The grounding device consists of grounding electrodes, grounding busbars, grounding down conductors, and frame grounding. The grounding device is also called the grounding integration device: a device that forms an electrical connection between electrical equipment or other objects and the ground (building electrical construction technology). The grounding device consists of grounding electrodes (plates), grounding busbars (indoors, outdoors), grounding down conductors (grounding jumper wires), and frame grounding. It is used to achieve the purpose ...

AI Technical Summary

Problems solved by technology

[0003] When the current grounding device conducts a relatively large charge flow, if it cannot achieve rapid discharge, the charge flow will be hindered, and the on-site reverse breakdown will occur.

In addition, due to the unpredictable underground environment of wind farms or photovoltaic power stations, the traditional conductive columns will corrode under the immersion of rainwater, which will affect the safety of equipment, and the density of metal and soil is different. The soil contact is not close, which affects its electrical conductivity
