Tower grounding device and operation method

Abstract

The invention relates to a pole tower grounding device and an operation method, the pole tower grounding device comprises a tower foot, a clamping mechanism and a grounding mechanism, when the pole tower grounding device is used, the clamping mechanism and the tower foot are fixed firstly, a clamping head is rotated through a wrench, the clamping head drives a rotating shaft to rotate, then a sliding block is driven to move, and under the action of the sliding block, the grounding mechanism is fixed; the front clamping plate and the rear clamping plate can be close to or far away from each other at the same time, so that a tower foot is clamped, a grounding wire is placed in the semi-ring, the semi-ring is buckled and pressed, the grounding wire is fixed in the lantern ring, the lower end of the grounding wire is connected with the grounding mechanism, the grounding mechanism is composed of a middle rod and a bottom rod, and current can be rapidly guided into soil through shunting needles on the outer side of the middle rod. The current diffusing capability of the grounding mechanism can be improved, the contact area between the grounding mechanism and the ground can be increased through the diffusing balls on the outer side of the bottom rod, large current can be evacuated in time, and use safety is guaranteed. The grounding device has the advantages of being firm in installation, high in stability and good in grounding effect.

Description

technical field [0001] The invention belongs to the technical field of pole tower grounding devices, and in particular relates to a pole tower grounding device and an operation method. Background technique [0002] The grounding device refers to the general term for the grounding electrode buried in the ground and the connecting wire from the grounding electrode to the equipment. The grounding device is composed of a grounding body (round steel, angle steel, flat steel, steel pipe, etc.) With the continuous increase of power transmission capacity of the power grid, when the transmission line fails, the magnitude of the short-circuit current will also continue to increase. Insulator grounding short-circuit fault occurs in the room, etc. In order to ensure the safety of power grid operation, it is necessary to flow the large current on the upper side of the power line into the ground through the grounding wire to avoid tripping of the power line. The existing grounding device ...

[0002] The grounding device refers to the general term for the grounding electrode buried in the ground and the connecting wire from the grounding electrode to the equipment. The grounding device is composed of a grounding body (round steel, angle steel, flat steel, steel pipe, etc.) With the continuous increase of power transmission capacity of the power grid, when the transmission line fails, the magnitude of the short-circuit current will also continue to increase. Insulator grounding short-circuit fault occurs in the room, etc. In order to ensure the safety of power grid operation, it is necessary to flow the large current on the upper side of the power line into the ground through the grounding wire to avoid tripping of the power line. The existing grounding device is extremely inconvenient to install. It does not need to be fixed, and the contact area with the ground is small, which cannot meet the requirements of large current discharge to the ground
