Abstract
The invention discloses a kind of solar cell plate earthing conductive structure, described ground connection conductive structure comprise steel construction crossbeam, be arranged on solar panel on this crossbeam and conductive spacer, this conductive spacer is arranged on this crossbeam and with the metal edge frame of this solar panel and is connected.The present invention, by conductive spacer, is placed directly in the relevant position of steel structure beam, and the metal edge frame of every block solar panel is all conducted with gooseneck, ground connection is very reliable, and easy construction, does not have bolt to connect, greatly reduce site operation workload and the number of components, reduce construction cost.And there is multiple spot at the position that every block solar panel and gooseneck conduct, can ensure the lightning protection effect of whole photovoltaic system completely.
Description
Technical field
The present invention relates to the lightning protection of photovoltaic surface power station and grounding technology, be specifically related to a kind of photovoltaic ground connection conductive structure, before installing the solar panel, directly on U-shaped gooseneck, place ground connection conducting strip, the aluminium frame of every block solar panel is all conducted with U-shaped gooseneck, to connect without the need to bolt and earth-continuity is reliable, greatly reduce site operation workload.
Background technology
Solar photo-voltaic power generation station, general floor space is larger, and solar panel is many, and repetitive operation is general.According to lightning protection and the grounding requirement of photovoltaic plant, require that the aluminium frame of every block solar panel should adopt reliable equipotential to be electrically connected and earth-continuity.The way of conventional photovoltaic plant lightning protection, the aluminium frame of solar panel, is serially connected by yellowish green wire, at the ground hole that the aluminium frame of every block assembly is reserved, wears bolt fixed copper nose, assembly is electrically connected by yellowish green wire.This way, on-site installation work amount is comparatively large, and in color steel watt steel-structure roof, time solar panel is laid in roof, operating space is very little.General solar panel aluminum border, in order to increase corrosion resistance and case hardness and intensity, all carry out anodized, aluminum alloy frame outer surface is made to have layer oxide film, and this oxide-film is nonconducting, when equipotential is electrically connected, after the oxide-film of connecting portion should being removed, conducting between solar panel could be realized.Because yellow/green cable is connected with solar panel frame with bolt, need the power that bolted is certain, just can rub the oxide-film of aluminum alloy frame, if the place of not rubbing, just cannot conduct, it is invalid for not having the lightning protection of conducting to connect.
Summary of the invention
The object of the invention is the deficiency overcoming prior art, provide a kind of brand-new solar cell plate earthing conductive structure, by the photovoltaic ground connection conducting strip arranged on U-shaped gooseneck, connect without the need to bolt, ground connection is reliable, greatly reduces site operation workload.
The technical scheme realizing the object of the invention is as described below:
A kind of solar cell plate earthing conductive structure, it is characterized in that: described ground connection conductive structure comprise steel construction crossbeam, be arranged on solar panel on this crossbeam and conductive spacer, this conductive spacer is arranged on this crossbeam and with the metal edge frame of this solar panel and is connected.
Further, described crossbeam is U-shaped steel construction, and described conductive spacer has a U-shaped groove, and this U-shaped groove is fastened on this crossbeam and with the metal edge frame of this solar panel and is connected.
Described conductive spacer has circular hole burr.
Described conductive spacer adopts stainless steel material to make.
Solar cell plate earthing conductive structure provided by the invention, utilize the conductive spacer be made up as stainless steel thin slice of electric conducting material being designed to match with beam shape, before installing the solar panel, be placed directly in the relevant position of steel structure beam, the metal edge frame of every block solar panel is all conducted with gooseneck, ground connection is very reliable, it instead of the numerous yellow/green cable needed for original solar panel ground structure, copper lug, bolt, nut, the parts such as pad, easy construction, bolt is not had to connect, be placed directly on crossbeam, greatly reduce site operation workload and the number of components, reduce construction cost.And there is multiple spot (installing multiple conductive spacer) at the position that every block solar panel and gooseneck conduct, can ensure the lightning protection effect of whole photovoltaic system completely.Conductive spacer provided by the invention, design considers the connection request with other accessory of photovoltaic system completely, and the width of conductive spacer central aperture meets the installation of rectangular nut and plastics cutting ferrule, can not interfere.Conductive spacer has been taken into account and the combination of the photovoltaic plant mounting structure of gooseneck type and easy construction, solves the series of problems such as installation and earth-continuity quality of solar panel lightning protection.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described:
The structural representation of the present embodiment solar cell plate earthing conductive structure shown in Fig. 1, it comprise U-shaped steel construction crossbeam 1, be arranged on solar panel 2 on this crossbeam 1 and conductive spacer 3, this conductive spacer 3 adopts stainless steel thin slice to make.
This conductive spacer 3 structure is as Fig. 2, and it has a U-shaped groove 4, is fastened on this crossbeam 1 by this U-shaped groove 4, and is connected with aluminum alloy frame 5, as Fig. 3, Fig. 4 by the aluminium alloy briquetting 9 of fixed solar cell panel 2.
Conductive spacer 3 adopts the method for punching burr, on Product processing, shaping by 304 stainless sheet steel mould punching, and speed of production is fast, and cost is low.Thin plate turns down 90 ° of wing limits, and the width design on both wings limit is the outer wide of U-shaped gooseneck 1, can be stuck in easily on the flange plate of U-shaped gooseneck 1.The spacing of interstitial hole 7, the size of coincide rectangular nut 10 and plastics cutting ferrule 8, installs and does not have any interference; Circular hole burr 6 is gone out in relevant position, corner, circular hole burr keeps sharp, when mounted, the circular hole burr 6 on this conductive spacer 3 can puncture the oxide-film of solar panel 2 aluminum alloy frame 5, solar panel 2 aluminum alloy frame 5 and U-shaped gooseneck 1 is formed and conducts.By arranging multiple conductive spacer 3 on crossbeam 1, there is multiple spot at the position that every block solar panel 2 and U-shaped gooseneck 1 are conducted, can ensure the lightning protection effect of whole photovoltaic system completely.The material economized most of the design, completes the design of conductive spacer 3, and with all parts coordinate requirement, simple and practical, reduce input cost, fast easy to process, supply of material speed is fast.
