The beneficial effect of the utility model as follows: connecing through testing electric linkage with insulated wire and ground connection, making lightning protection cross arm insulator self possess ground connection and test the electric installation, the difficult problem of electricity protection is tested to ground connection when having solved the tradition and joining in marriage net, built on stilts insulating circuit and the maintenance of transformer platform district. In addition, through be equipped with the starting rod on fixed gold utensil through the cross arm and the cross arm gold utensil respectively in cross arm insulator, make to have possessed discharge gap on the cross arm insulator to make ordinary cross arm insulator take into account the lightning protection function on the insulated wire way, effectively solved the emergence of insulating circuit because of thunderbolt broken string and insulator flashover accident.
Description
Technical field
The utility model relates to electric protection device technical field, refers to a kind of cross arm of lightning protection insulator of electroscopic device with ground especially.
Background technology
Insulator is a kind of special insulation control, can play an important role in overhead transmission line.Insulator should not to change the various dynamo-electric stress that causes and losing efficacy due to environment and electric loading condition, otherwise insulator would not produce great effect, will damage use and the service life of whole piece circuit.Insulator is used to support and fixing bus and energized conductor, can make between energized conductor or conductor and greatly between have enough Distance geometry to insulate.
Conventional insulators is not owing to establishing electroscopic device, and when keeping in repair power station, ground protection is more difficult.
In addition, though be provided with lightning arrester on the upside of the inlet wire of power station, checking not in place and losing efficacy may appear in its long-play, and so just easy transformer and the distribution facility of damaging because of thunderbolt, therefore, in the urgent need to installing lightning arrester additional on the insulator.
Utility model content
The utility model proposes a kind of cross arm of lightning protection insulator of electroscopic device with ground, solve the problem of ground protection difficulty when traditional power station is keeped in repair in prior art.
The technical solution of the utility model is achieved in that
A cross arm of lightning protection insulator for electroscopic device with ground, comprising: cross arm insulator, is arranged on the insulation mandrel in described cross arm insulator, ground connection electrical verification ring, and cross-arm props up line end and insulated conductor; Described cross-arm is propped up between line end with described insulated conductor and is fixedly connected with by the hood type bilateral mode of puncture; Described ground connection electrical verification ring is connected with described insulated conductor; By the fixing gold utensil of cross-arm and cross-arm gold utensil are respectively equipped with starting rod in described cross arm insulator.
As preferably, the outside of described ground connection electrical verification ring is provided with layer of silica gel.
The beneficial effects of the utility model are:
By being connected with ground connection electrical verification ring by insulated conductor, cross arm of lightning protection insulator is made self to have possessed ground connection electroscopic device, the problem of ground connection electrical verification protection difficulty when solving traditional distribution, insulated overhead line and become radio area maintenance.In addition, by in cross arm insulator by the fixing gold utensil of cross-arm and cross-arm gold utensil are respectively equipped with starting rod, make cross arm insulator to have possessed discharging gap, thus make common cross arm insulator on insulated circuit, take into account lightning protection function, efficiently solve the generation of insulated circuit because of lightning-caused breaking and insulator arc-over accident, the effect of lightning-arrest defence line is played in transformer station, avoid because of lightning arrester long-play on the upside of transforming plant lead-in or damage transformer and distribution facility after checking inefficacy not in place, playing better protective action.
By in ground connection electrical verification ring arranged outside layer of silica gel, can prevent branch or birds fall upper after there is short circuit accident.
Adopt the hood type bilateral mode of puncture to be connected by cross-arm being propped up line end and insulated conductor, changing traditional lashing wire mode, is that lashing wire firmly not easily drops.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment is as Figure 1-Figure 2 known, the cross arm of lightning protection insulator of a kind of electroscopic device with ground described in the utility model, comprising: cross arm insulator 1, is arranged on the insulation mandrel 2 in cross arm insulator 1, ground connection electrical verification ring 3, cross-arm props up line end 5 and insulated conductor 6; Cross-arm is propped up between line end 5 with insulated conductor 6 and is fixedly connected with by the hood type bilateral mode of puncture; Ground connection electrical verification ring 3 is connected with insulated conductor 6; By the fixing gold utensil of cross-arm and cross-arm gold utensil are respectively equipped with starting rod 7 in cross arm insulator 1.
By being connected with ground connection electrical verification ring by insulated conductor, cross arm of lightning protection insulator is made self to have possessed ground connection electroscopic device, the problem of ground connection electrical verification protection difficulty when solving traditional distribution, insulated overhead line and become radio area maintenance.
In addition, by in cross arm insulator by the fixing gold utensil of cross-arm and cross-arm gold utensil are respectively equipped with starting rod, make cross arm insulator to have possessed discharging gap, thus make common cross arm insulator on insulated circuit, take into account lightning protection function, efficiently solve the generation of insulated circuit because of lightning-caused breaking and insulator arc-over accident, the effect of lightning-arrest defence line is played in transformer station, avoid because of lightning arrester long-play on the upside of transforming plant lead-in or damage transformer and distribution facility after checking inefficacy not in place, playing better protective action.
Adopt the hood type bilateral mode of puncture to be connected by cross-arm being propped up line end and insulated conductor, changing traditional lashing wire mode, is that lashing wire firmly not easily drops.
The outside of above-mentioned ground connection electrical verification ring 3 is provided with layer of silica gel 4.
By in ground connection electrical verification ring arranged outside layer of silica gel, can prevent branch or birds fall upper after there is short circuit accident.
