Abstract
The utility model relates to a kind of earthing device on substation equipment, comprise ground, substation equipment, described substation equipment lower end is connected with L-type connector horizontal segment by some groups of the first bolt groups, both sides, described L-type connector lower end are connected with the vertical section of F type connector by some groups of the second bolt groups, and described F type connector horizontal segment is positioned at ground and is provided with and falls resistance dielectric layer.Utility model falls resistance dielectric layer by setting; effectively can change media environment like this, reduce dielectric resistance, shorten the fault offset time; thus avoid the neutral point potential be struck by lightning, short trouble causes to raise; to reach the object of protection power equipment, building and personal security; by the pre-buried earthing device of F type connector simultaneously when constructing; L-type connector is connected with F type connector by the first bolt group, the second bolt group when installing substation equipment; such speed of application is fast, time saving and energy saving and connection reliability good.
Description
Technical field
The utility model relates to technical field of electricity, particularly relates to a kind of earthing device on substation equipment.
Background technology
Equipment, refers to supply people's Long-Time Service aborning, and substantially in Reusability keeps original physical form and the means of production of function and the general name of material goods.Equipment has common apparatus, special equipment, common apparatus comprises plant equipment, electric equipment, special equipment, office equipment, haulage vehicle, instrument and meter, computer techno-stress equipment etc., and special equipment comprises mine special equipment, special chemical equipment, Aero-Space special equipment, public security fire-fighting special equipment etc.
Along with the fast development of electric utility, the quantity of transformer station also increases severely thereupon fast, and the major issue that the fail safe of transformer station is people to be paid close attention to.In the major measure that transformer station's installing lightning rod is protection direct lightning strike, thunder and lightning is attracted on one's body by lightning rod, and safety imports underground, thus protection electric equipment and building exempt from thunderbolt.A unified ground network also will be laid after installing lightning rod by general transformer station according to the requirement of safety and working earthing, but current ground network exists and reduces earth resistance DeGrain and the high problem of cost.Substation equipment ground connection needs corresponding earthing device to implement simultaneously.Earthing device needs to be embedded in major structure of construction usually, as inferior in wall, ground.The pre-buried earthing device of substation equipment common at present, or agree with not with building body, easily stay dew ledge; After pre-buried, when substation equipment is installed, can not interface flexibility with the earthing position of equipment, cause equipment that difficulty is installed.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of earthing device on substation equipment.
The utility model is achieved through the following technical solutions:
A kind of earthing device on substation equipment, comprise ground, substation equipment, described substation equipment lower end is connected with L-type connector horizontal segment by some groups of the first bolt groups, both sides, described L-type connector lower end are connected with the vertical section of F type connector by some groups of the second bolt groups, and described F type connector horizontal segment is positioned at ground and is provided with and falls resistance dielectric layer.
As optimal technical scheme of the present utility model, described L-type connector, F type connector are zinc-coated flat steel sheet.
As optimal technical scheme of the present utility model, described second bolt group is interlaced arrangement in the vertical section of F type connector.
As optimal technical scheme of the present utility model, described in fall resistance dielectric layer be embedded in ground.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model falls resistance dielectric layer by setting, effectively can change media environment like this, reduce dielectric resistance, shorten the fault offset time, thus avoid the neutral point potential be struck by lightning, short trouble causes to raise, to reach the object of protection power equipment, building and personal security; By arranging L-type connector, F type connector, by the pre-buried earthing device of F type connector during such construction, be connected with F type connector by L-type connector by the first bolt group, the second bolt group when installing substation equipment, such speed of application is soon, time saving and energy saving and connection reliability good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. ground; 2. substation equipment; 3.L type connector; 4. the first bolt group; 5. the second bolt group; 6.F type connector; 7. resistance dielectric layer falls.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of earthing device on substation equipment, comprise ground 1, substation equipment 2, described substation equipment 2 lower end is connected with L-type connector 3 horizontal segment by some groups of the first bolt groups 4, both sides, described L-type connector 3 lower end are connected with the vertical section of F type connector 6 by some groups of the second bolt groups 5, wherein said L-type connector 3, F type connector 6 is zinc-coated flat steel sheet, adopt zinc-coated flat steel sheet as earth electrode, easy making, cost is lower, in addition, it is closely knit that falling between zinc-coated flat steel sheet and hole, brill ground hinders Filled Dielectrics, contact is good, thus resistance reducing effect is obvious.
Described second bolt group 5 in interlaced arrangement, improves the reliability connected in the vertical section of F type connector 6.By the pre-buried earthing device of F type connector 6 during such construction, by the first bolt group 4, second bolt group 5, L-type is connected 3 be connected with F type connector 6 when installing substation equipment, such speed of application is soon, time saving and energy saving and connection reliability good.Described F type connector 6 horizontal segment be positioned at ground 1 be provided with fall resistance dielectric layer 7; the wherein said resistance dielectric layer 7 that falls is embedded in ground 1; fall resistance dielectric layer 7 so effectively to change media environment, reduce dielectric resistance, shorten the fault offset time; thus avoid the neutral point potential be struck by lightning, short trouble causes to raise, to reach the object of protection power equipment, building and personal security.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
