Description

Simply connected insulator string lightning protection inter space arcing horn
Technical field
The utility model belongs to lightning protection inter space arcing horn technical field, particularly relates to a kind of simply connected insulator string lightning protection inter space 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 provide one can not rely on the connection of former insulator string, play lightning protection effect simultaneously, increase the applicable installing insulating substring of lightning protection inter space arcing horn, guarantee the simply connected insulator string lightning protection inter space arcing horn that circuit stability and safety is run.
The purpose of this utility model has been come by following technical solution.This simply connected insulator string lightning protection inter space arcing horn, be made up of cross-arm-end arcing horn, right angle link plate, conductor wire end arcing horn and cross link plate, described cross-arm-end arcing horn and conductor wire end arcing horn manufacture with round steel, the cross section of cross-arm-end arcing horn is the W shape of straightway in centre, straightway is connected with right angle link plate; The cross section of conductor wire end arcing horn is the V-arrangement of straightway in centre, and middle straightway is connected with cross link plate, and conductor wire end arcing horn is provided with ball in end; Described cross-arm-end arcing horn is connected with right angle link plate and is connected in series in insulator string; Described conductor wire end arcing horn is connected with cross link plate and is connected in series in insulator string.
As preferably, the connection of described cross-arm-end arcing horn and the connection of right angle link plate, conductor wire end arcing horn and cross link plate is diplopore and connects, and the position that its diplopore is offered all is located at the center of cross-arm-end arcing horn, conductor wire end arcing horn.
The beneficial effects of the utility model are: one is adopt to increase 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 shape of other gold utensils on insulator string, make the installation of arcing horn, replacing more simple, rapid; Two is that arcing horn adopts diplopore to connect, and the gap change avoiding arcing horn to cause because of rotation in the line, makes operation more stable.
