Abstract
The utility model relates to arcing horn under a kind of anti-flashover parallel connection gaps, be made up of charged gap installation link plate, coupling, downside steel pipe, link plate rubber, it is be fixed on socket-clevis eye by stove bolt and stud that link plate is installed in charged gap, coupling is welded by one block of side plate and two pieces of connecting plates, downside steel pipe is connected and fixed on the side plate of coupling by welding manner, and be bolted on charged gap installation link plate by two pieces of connecting plates utilizations, link plate rubber sleeve is installed on the stove bolt of link plate in charged gap; Side plate in coupling and rectangular shape between connecting plate.The beneficial effects of the utility model are: one is adopt to increase charged gap installation link plate, thus does not rely on and the connecting hole being connected gold utensil in insulator string, makes the installation of arcing horn not need to change the length of whole serial type simultaneously; Two is that arcing horn adopts multiple bolt to be connected and fixed, and the gap change avoiding arcing horn to cause because of rotation in the line, makes operation more stable.
Description
Technical field
The utility model belongs to lightning protection inter space arcing horn technical field; particularly relate to a kind of when not increasing serial type length; can engineering demands transmission line arcing horn install, and can realize lightning protection need anti-flashover parallel connection gaps under arcing horn.
Background technology
Transmission line is located in wilderness, is subject to thunderbolt.Because of the lightning induced voltage that ground near the thunderbolt direct lightning strike overvoltage that causes of circuit and thunderbolt circuit causes, i.e. the atmospheric over-voltage of normal appearance on so-called transmission line.Insulator arc-over, line tripping and lightning surge intrusion electric substation damage converting equipment accident that it causes account for very large percentage in power grid accident.These accidents caused for preventing atmospheric over-voltage, lightning conducter (overhead ground wire), lightning rod and multi-form lightning arrester etc. have been installed by power circuit and electric substation.Arcing horn is as one of effective lightning protection device; insulator string end is arranged on certain greeting gap; the breakdown voltage of this arcing horn is lower than the breakdown voltage of insulator string; therefore can puncture by preferential insulator string when transmission pressure suffers thunderbolt; lightning current is leaked into the earth fast, thus the calcination protecting the power frequency continued flow electric arc after insulator string punctures gap from thunder and lightning damages.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and arcing horn under a kind of anti-flashover parallel connection gaps is provided, the anti-flashover arcing horn of serial type length can not be increased, play lightning protection effect simultaneously, increase the applicable installing insulating substring of lightning protection inter space arcing horn, guarantee the operation of circuit stability and safety.
The purpose of this utility model has been come by following technical solution.Arcing horn under this anti-flashover parallel connection gaps, by charged gap, link plate is installed, coupling, downside steel pipe, link plate rubber forms, it is be fixed on socket-clevis eye by stove bolt and stud that link plate is installed in described charged gap, described coupling is welded by one block of side plate and two pieces of connecting plates, described downside steel pipe is connected and fixed on the side plate of coupling by welding manner, and be bolted on charged gap installation link plate by two pieces of connecting plates utilizations, described link plate rubber sleeve is installed on the stove bolt of link plate in charged gap, side plate in described coupling and rectangular shape between connecting plate.
As preferably, described downside steel pipe adopts the steel pipe manufacture of Φ 52x2.5 to form, and is bent into space circle arcuation in end.
The beneficial effects of the utility model are: one is adopt to increase charged gap installation link plate, thus do not rely on and the connecting hole being connected gold utensil in insulator string, make the installation of arcing horn not need to change the length of whole serial type simultaneously, also make the installation of arcing horn, replacing more simple, rapid; Two is that arcing horn adopts multiple bolt to be connected and fixed, and the gap change avoiding arcing horn to cause because of rotation in the line, makes operation more stable.

Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in accompanying drawing 1 to 8, the utility model installs link plate 1 by charged gap, coupling 2, downside steel pipe 3, link plate rubber 4 forms, it is be fixed on socket-clevis eye 8 by stove bolt 5 and stud 6 that link plate 1 is installed in described charged gap, described coupling 2 is welded by one block of side plate 21 and two pieces of connecting plates 22, described downside steel pipe 3 is connected and fixed on the side plate 21 of coupling 2 by welding manner, and utilize bolt 7 to be fixed on charged gap installation link plate 1 by two pieces of connecting plates 22, described link plate rubber 4 is enclosed within charged gap and installs on the stove bolt 5 of link plate 1, prevent thread damage.
It is utilize stove bolt 5 and stud 6 to be fixed on corresponding socket-clevis eye 8 that link plate 1 is installed in described charged gap, and such installing/dismounting is convenient, does not increase the length of whole serial type simultaneously, and is manufacture by normalized treatment with 35#, has enough hardness.
Side plate 21 in described coupling 2 and rectangular shape between connecting plate 22; Described downside steel pipe 3 adopts the steel pipe manufacture of Φ 52x2.5 to form, and is bent into space circle arcuation in end.
The utility model is not limited to above-mentioned execution mode; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection range.
