Concrete pole with grounding integration function

Abstract

The invention relates to a concrete pole with a grounding integration function, belonging to the field of grounding devices. According to the concrete pole, a non-prestressed ground rebar used as a built-in ground down lead is arranged inside a concrete pole body; the bottom of the concrete pole is provided with a ground pipe bracket, and the non-prestressed ground rebar and the ground pipe bracket are fixedly connected into a whole; a grounding electrode is arranged below the ground pipe bracket, and the grounding electrode and the ground pipe bracket are fixedly connected into a whole; and the non-prestressed ground rebar, the ground pipe bracket and the grounding electrode form a grounding electrode system of the concrete pole. The concrete pole has the advantages that the theft incidents of the grounding system of the concrete pole are reduced, and personal and equipment accidents of line lightning stroke and electric shock, caused by the condition that ground pipes and down leads of a power supply line are stolen, are avoided, so that the safe and reliable operation of an electricity supply grid is ensured; the ground down lead structure formed by the ground pipe and the down lead, of the prior pole is eliminated, so that the advantages of cost saving and energy conservation and environment protection are provided, and poles on the urban streets are enabled to be more beautiful visually.

Description

technical field [0001] The invention belongs to the field of grounding devices for special purposes, in particular to a grounding device for concrete electric poles. Background technique [0002] According to the National Electric Power DL / T621-1997 "Grounding of AC Electrical Installations" standard and related electrical safety operating procedures, when installing and using cement poles, ground wires must be connected. [0003] The use of concrete poles for power supply in my country has a history of more than 100 years, and the use of grounding pipes as ground wires has a history of more than 80 years in actual power supply operations. [0004] The United States mainly uses wooden poles for 35kV and below, and a small amount of aluminum alloy poles, steel poles and composite material poles are used in a small amount. [0005] European Germany, France, and the United Kingdom mainly use steel poles and concrete poles. [0006] Northern Europe mainly uses wooden poles. ...

AI Technical Summary

Problems solved by technology

However, it has the disadvantage that the grounding down-conductor device exposes the outer surface of the concrete pole body, which cannot prevent the theft of the grounding pipe and down-conductor on the power supply line. When the line or pole is struck by lightning, there is a large lightning impact resistance. And the grounding electrode still needs to be constructed separately and cannot be combined with the vertical pole operation of the concrete pole
