Abstract
The utility model discloses a specialized grounding terminal structure of a GIS combined electric appliance, comprising a connecting bolt, a grounding pressure welding plate, a first grounding bar, a second grounding bar and a channel steel. The connecting bolt and the grounding pressure welding plate fix the first and second grounding bars on the channel steel. By using the connecting bolt and the grounding pressure welding plate to fix the first and second grounding bars on the channel steel, the construction is convenient, the workload and the construction difficulty are reduced, the construction fee and cost are saved, and the connection reliability of the specialized grounding terminal and a main grounding grid is guaranteed.
Description
Technical field
The utility model relates to a kind of earth terminal, particularly relates to a kind of GIS combined electrical apparatus Special grounding terminal structure.
Background technology
Along with town site day is becoming tight, the advantages such as the GIS power distribution equipment is little owing to its volume, characteristics of compact layout, installation and transportation convenience are widely applied.The ground connection of GIS power distribution equipment and conventional outdoor power distribution unit have a great difference, except all basic embedded parts need to main grounding grid is connected, also need the more Special grounding terminal of magnitude setting.How the Special grounding terminal reasonably is set and is each design and installation unit, producer research outline with reliable connection of itself and main grounding grid always.
On the whole, form and the connected mode thereof of GIS Special grounding terminal mainly contain two kinds at present, a kind of for adopting ground plate as GIS Special grounding terminal, as shown in Figure 1, comprise, be embedded in the ground plate 3 on the flooring, the upper surface of ground plate 3 5mm above ground level, the top of ground plate 3 and bottom are connected respectively the first earthing bar 4 and the second earthing bar 6, the first earthing bar 4 is fixedly connected on the ground plate 3 by connecting bolt 1 and earth contact pressure fishplate bar 2, this first earthing bar 4 is connected with GIS body earth terminal, is welded to connect between ground plate 3 and the second earthing bar 6, and this second earthing bar 6 is connected with main grounding grid.In the use procedure of reality, employing is welded to connect, and earth point is more, and the welding job amount is large, and the expense of welding is higher, and welding process and welding quality are difficult to control, and is difficult to satisfy the technological requirement of lacking welding or cancellation welding in the production.The series of problems that produces in order to solve the welding link simultaneously in order to simplify technique, discloses the vertical earthing bar of another kind of use as GIS Special grounding terminal, and earthing bar directly connects main grounding grid and GIS body earth terminal.But the face length degree is larger highlightedly for this kind Special grounding terminal (earthing bar), installs to GIS transportation and brings larger difficulty, and install and have directivity, need guarantee that wide of earthing bar is over against GIS body earth terminal.
Because the defective that above-mentioned existing GIS Special grounding terminal exists, the design people, actively research and innovation in addition in the hope of founding a kind of GIS combined electrical apparatus Special grounding terminal structure of new structure, makes it have more practicality.
The utility model content
Main purpose of the present utility model is, overcome the defective that existing GIS Special grounding terminal exists, and provide a kind of GIS combined electrical apparatus Special grounding terminal structure of new structure, technical problem to be solved is the cancellation welding, guarantee that the Special grounding terminal reliably is connected with main grounding grid, be convenient to installation, thereby more be suitable for practicality, and have value on the industry.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to the GIS combined electrical apparatus Special grounding terminal structure that the utility model proposes, comprise connecting bolt, earth contact pressure fishplate bar, the first earthing bar and the second earthing bar, it also comprises channel-section steel, described connecting bolt and earth contact pressure fishplate bar are fixed on the first earthing bar and the second earthing bar on the described channel-section steel.
Aforesaid GIS combined electrical apparatus Special grounding terminal structure, wherein, described the second earthing bar is on the ground pre-buried, and this second earthing bar is connected directly to indoor main grounding grid, its upper surface 5mm above ground level.
Aforesaid GIS combined electrical apparatus Special grounding terminal structure, wherein, described connecting bolt is two.
By technique scheme, the utility model GIS combined electrical apparatus Special grounding terminal structure has following advantages at least:
Adopt connecting bolt and earth contact pressure fishplate bar that the first earthing bar and the second earthing bar are fixed on the channel-section steel, the welding link has been cancelled in easy construction, has reduced workload, has reduced difficulty of construction, has saved operating expenses and cost; Guaranteed the reliability that the Special grounding terminal is connected with main grounding grid.
In sum, the GIS combined electrical apparatus Special grounding terminal structure of the utility model special construction, it has above-mentioned many advantages and practical value, thereby more is suitable for practicality.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.
Description of drawings
Fig. 1 adopts ground plate as the structural representation of GIS Special grounding terminal in the background technology;
Fig. 2 is the structural representation of GIS combined electrical apparatus Special grounding terminal described in the utility model.
Embodiment
Be to reach technological means and the effect that predetermined utility model purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, embodiment of the present utility model be described in detail as follows.
As shown in Figure 1, GIS combined electrical apparatus Special grounding terminal structure comprises two connecting bolts 7, earth contact pressure fishplate bar 8, the first earthing bar 9 and the second earthing bar 10, and it also comprises channel-section steel 11.Connecting bolt 7 and earth contact pressure fishplate bar 8 are fixed on the first earthing bar 9 and the second earthing bar 10 on the channel-section steel 11, have cancelled being welded to connect, and have simplified technique.The second earthing bar 10 is on the ground pre-buried, directly causes main grounding grid, and the upper surface of this second earthing bar 10 is 5mm above ground level only, is convenient to the installation of equipment conveying and equipment.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
