Abstract
The utility model provides a lightning protection device for a high-voltage power transmission tower, which mainly comprises a lightning receiver, a down lead, and a radial grounding device, wherein the lightning receiver is arranged at the top of the high-voltage power transmission tower; the down lead is independently installed along the tower body main material from the tower top and led downwardly to the underground; the radial grounding device is arranged into a metal radial structure buried under the ground and in conductive connection with the down lead; the radial grounding device has a metal radial structure formed by a plurality of metal needle-shaped items and one end of each metal needle-shaped item is welded and gathered to one point; the radial grounding device is in conductive connection with the down lead via the end part where the metal needle-shaped items are welded to one point; the radial grounding device is a copper radial grounding device, or a silver radial grounding device or an iron radial grounding device; and the lightning receiver is a needle-shaped lightning receiver. According to the lightning protection device, the tower body is not charged even in the case of lightning stroke, and the lightning protection effects are ideal.
Description
Technical field
The utility model relates to power supply unit field, refers to especially a kind of high voltage power transmission tower lightning arrester.
Background technology
The existing shocking preventing technology of high voltage power transmission tower generally sets up one or two lightning conducters and completes lightning protection effect at the top of tower, and because high voltage power transmission tower this as metal material, so do not adopt downlead, but replace downlead conduction thunder and lightning with metal tower body, although but this kind of lightning-arrest mode is simple, but causing the whole tower body of thunderstorm weather is all electric conductor, exists non-safety factor.And this kind of lightning-arrest mode, lightning-arrest effect is not good.
Utility model content
The utility model proposes a kind of high voltage power transmission tower lightning arrester, the high voltage power transmission tower that is applicable to supply line is lightning-arrest, and better lightning-arrest effect can be provided.
The technical solution of the utility model is achieved in that
A kind of high voltage power transmission tower lightning arrester, is characterized in that, comprising:
Arrester, is arranged on high voltage power transmission column overhead;
Downlead, lay separately from tower top along the main material of tower body and descending cause underground;
Radial earthing device, is set to one and is embedded in underground metal radial structure, and conduction connects described downlead.
In technique scheme, described arrester is preferably needle-like arrester.
In technique scheme, the serve as reasons metal radial structure of many metal spicules composition of described radial earthing device, one end welding of each described metal spicule is gathered in a bit.
Further, in technique scheme, the end conduction that described radial earthing device is welded in any by described metal spicule connects described downlead.
In technique scheme, described radial earthing device is the radial earthing device of copper or silver-colored radial earthing device or the radial earthing device of iron.
In sum, because the utility model adopts arrester, lays separately and descendingly cause underground downlead and form lightning arrester by the netted earthing device of more excellent conductivity from tower top along the main material of tower body, even if tower body can be not charged yet when making thunderbolt, and earth resistance is lower, thereby lightning protection effect is more desirable.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of high voltage power transmission tower lightning arrester;
1-arrester; 2-downlead; The radial earthing device of 3-.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, high voltage power transmission tower lightning arrester of the present utility model, its agent structure comprises:
Downlead 2, lay separately from tower top along the main material of tower body and descending cause underground;
In technique scheme, lay separately downlead 2 from tower top along the main material of tower body, can adopt the mode of laying downlead 2 along the main material inner surface of tower body, as long as guarantee that downlead 2 and tower body master metal material do not contact, conduction insulation mutually.
In technique scheme, described arrester 1 is preferably needle-like arrester.
In technique scheme, the serve as reasons metal radial structure of many metal spicules composition of described radial earthing device 3, one end welding of each described metal spicule is gathered in a bit.
Further, in technique scheme, the end conduction that described radial earthing device 3 is welded in any by described metal spicule connects described downlead 2.
In technique scheme, described radial earthing device 3 is the radial earthing device of copper or silver-colored radial earthing device or the radial earthing device of iron.
Certainly any metal with satisfactory electrical conductivity can be used for manufacturing radial earthing device 3 of the present utility model.
In sum, because the utility model adopts arrester, lays separately and descendingly cause underground downlead and form lightning arrester by the netted earthing device of more excellent conductivity from tower top along the main material of tower body, even if tower body can be not charged yet when making thunderbolt, and earth resistance is lower, thereby lightning protection effect is more desirable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
