Problems solved by technology

[0002] Traditional power transmission poles and towers are generally made of steel materials. In remote mountainous areas, due to the heavy weight of wood and steel, large volume, high transportation costs and inconvenient erection, my country has gradually begun to use composite power poles and towers, which are light in weight and easy to process. and installation, etc., but the traditional steel itself can conduct electricity, so there is no need to set up an additional grounding lead. Therefore, for insulating composite towers, how to set up a solid grounding device with good lightning protection effect has become a technical difficulty

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] In order to solve the problem that the composite material tower cannot be grounded by its own properties and the surrounding environment of the tower cannot be predicted, the present invention provides a grounding method for a composite power tower and its tower. Refer to figure 1 and figure 2 , figure 1 It is a schematic diagram of the structure of the tower. The grounding method of the tower is to erect a section of metal cross-arm 2 on the grounding down-conductor vertically from the center of the ground cross-arm 1, and parallel to the tower from the end of the upper metal cross-arm 2....

Abstract

The invention relates to a composite-material power tower and a grounding method thereof, and belongs to the technical field of power transmission of a power system. A ground wire of the tower is grounded by erecting an upper metal cross-arm of a grounding down lead vertical to a ground wire cross-arm from the center of the ground wire cross-arm, erecting a tail-end insulated support rod downwardly from the tail end of the upper metal cross-arm in parallel with the tower, leading the grounding down lead in a Z shape from the tail end of the upper metal cross-arm, connecting the grounding down lead to the tower at a position under the tower, grounding along the lower half part of the tower, and providing an insulating and fixing device for the tail-end insulated support rod and the tower to fix and support the Z-shaped grounding down lead. A grounding down lead support structure is erected outside the composite-material tower, so that a grounding device is firm and durable, and disasters caused by thunder is prevented.

Description

technical field [0001] The invention belongs to the technical field of electric power system transmission, and in particular relates to a method for grounding a composite material power pole tower and the pole tower thereof. Background technique [0002] Traditional power transmission poles and towers are generally made of steel materials. In remote mountainous areas, due to the heavy weight of wood and steel, large volume, high transportation costs and inconvenient erection, my country has gradually begun to use composite power poles and towers, which are light in weight and easy to process. and installation, etc., but the traditional steel itself can conduct electricity, so there is no need to erect additional grounding leads. Therefore, for insulating composite towers, how to erect a solid grounding device with good lightning protection effect has become a technical difficulty. [0003] The outdoor power transmission corridor area is often located in a harsh climate area. ...
