Abstract
Name of the present utility model is called 10 kilovolts of platform district ground connection link devices.Belong to power supply unit technical field.The problem that it mainly solves.Its principal character is: comprise three identical ground connection flat copper bars; One end of described ground connection flat copper bar is provided with ground connection link recessed down, and all the other are straight shape flat copper bar; Described straight shape flat copper bar is respectively equipped with transformer high-voltage pile crown connecting hole and column support type lightning arrester connecting hole; Described ground connection flat copper bar is all surrounded by insulating case except ground connection link, transformer high-voltage pile crown connecting hole and column support type lightning arrester connecting hole.It is simple, attractive in appearance, swift to operate, convenient, with low cost that the utility model has installation, can complete the feature installing and removing ground connection in ground, be mainly used in the ground connection of 10 kilovolts of platform district buses.
Description
Technical field
The utility model belongs to power supply unit technical field, is specifically related to a kind of 10 kv transformer platform district ground connection link devices.
Background technology
In electric power system, 10 kv transformer platform districts, because of needs maintenance or other work, must take the safety measures such as power failure, electrical verification and hanging ground-wire.For preventing the generation of human casualty accident and power supply unit accident; according to national grid associate power Safety regulations stipulate; when 10 kilovolts of distribution transforming facility interruption maintenances; earth connection should be established in setting two ends; installing earth connection is to ensure that circuit homework personnel are among the protection of earth connection all the time, prevents circuit from surprisingly sending a telegram here or induced voltage causes personal injury.At present, be install ground loop on distribution facility mostly, hang over 10 kilovolts and cross on line bus, because bus itself is line body, material is soft, and its weak point one not easily mounts to retract in the middle of practical operation, operating difficulties; Two is easily draw bad by bus.
Summary of the invention
The purpose of this utility model is exactly provide a kind of installation simple, attractive in appearance, swift to operate, convenient for above-mentioned deficiency, can complete the 10 kilovolts of platform district ground connection link devices installing and removing ground connection in ground.
Technical solution of the present utility model is: a kind of 10 kilovolts of platform district ground connection link devices, is characterized in that: comprise three identical ground connection flat copper bars; One end of described ground connection flat copper bar is provided with ground connection link recessed down, and all the other are straight shape flat copper bar; Described straight shape flat copper bar is respectively equipped with transformer high-voltage pile crown connecting hole and column support type lightning arrester connecting hole; Described ground connection flat copper bar is all surrounded by insulating case except ground connection link, transformer high-voltage pile crown connecting hole and column support type lightning arrester connecting hole.
Ground connection link described in technical solution of the present utility model is rectangular channel.
Insulating case described in technical solution of the present utility model is transparent insulation cover.
The utility model is owing to adopting three identical ground connection flat copper bars, one end of described ground connection flat copper bar is provided with ground connection link recessed down, all the other are straight shape flat copper bar, straight shape flat copper bar is respectively equipped with transformer high-voltage pile crown connecting hole and column support type lightning arrester connecting hole, ground connection flat copper bar is except ground connection link, transformer high-voltage pile crown connecting hole and column support type lightning arrester connecting hole are all surrounded by insulating case outward, thus, only need be fixed on transformer high-voltage pile crown by the transformer high-voltage pile crown connecting hole correspondence on three ground connection flat copper bars during installation, be fixed on column support type lightning arrester by the column support type lightning arrester connecting hole correspondence on three ground connection flat copper bars, cross line bus by three and be connected to ground connection link outer end, install simple, attractive in appearance, during operation, because the general installation site of transformer is not high, therefore only need stand and can complete mounting or dismounting ground connection on the ground, swift to operate, convenient.It is simple, attractive in appearance, swift to operate, convenient, with low cost that the utility model has installation, can complete the feature installing and removing ground connection in ground.The utility model is mainly used in the ground connection of 10 kilovolts of platform district buses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1.The ground connection flat copper bar that three, the utility model 10 kilovolts of platform district ground connection link devices are identical.One end of ground connection flat copper bar is provided with ground connection link 8 recessed down, and ground connection link 8 is rectangular channel, and all the other are straight shape flat copper bar 3.On straight shape flat copper bar 3, outer end place is provided with transformer high-voltage pile crown connecting hole, to be fixed on the high-voltage pile 4 of transformer 5 by nut, packing ring.Straight shape flat copper bar 3 is abutted against link 8 end place, ground and is provided with column support type lightning arrester connecting hole, to be fixed on column support type lightning arrester 7 by nut, packing ring, column support type lightning arrester 7 is fixing on the frame 6.Ground connection flat copper bar is all surrounded by insulating case 2 except ground connection link 8, transformer high-voltage pile crown connecting hole and column support type lightning arrester connecting hole, and insulating case 2 is transparent insulation cover.Cross line bus 1 and be connected to ground connection link 8 outer end.
Claims (3)
