At present, the Large Cities ' Building such as Shanghai, Beijing many underground substations.The ground network of underground substation is generally positioned at foundation ditch bottom, ground connection main line need to be introduced transformer station by the large floor of foundation ditch, in the time that level of ground water is higher, ground connection main line draws that the place's hydraulic pressure of reaching the standard grade is higher, and water can penetrate into transformer station along ground connection main line, simultaneously when generation is when earth fault, have larger earth current and flow into ground network through ground connection main line, large electric current, by causing conventional ground connection main line dilation, makes generation gap, ground connection main line place, and water is from then on gap infiltration also.
In view of the particularity that underground substation ground network is laid and ground connection main line is introduced, routine is introduced from floor with grounding flat steel, flat copper, copper tree lace, can not meet the demands.Therefore, the inventor is devoted to develop one and compatibly descends substation grounding to use, and can meet larger earth current and pass through, and meets the underground substation waterproof ground connection main line of waterproof requirement.
Utility model content
Because the above-mentioned deficiency of prior art the utility model proposes one and compatibly descends substation grounding to use, can meet larger earth current and pass through, meet the underground substation waterproof ground connection main line of waterproof requirement.
For achieving the above object, the utility model provides a kind of underground substation waterproof ground connection main line, comprise the conductor for electric current being imported to grounding network cable, described ground connection main line also comprises seamless steel pipe, insulating packing, nonmetal detent plug head and water-stop tray, described insulating packing is filled in described seamless steel pipe, described in two, nonmetal detent plug head correspondence is arranged on the both ends of described seamless steel pipe, described water-stop tray winding is at described seamless steel pipe outer circumferential side, described nonmetal detent plug head offers the through hole wearing for described conductor in the axial direction, described conductor is located in described seamless steel pipe along extending axially of described seamless steel pipe, and the both ends of the described conductor respectively through hole from described nonmetal detent plug head pass.
Preferably, described conductor is heavy cross section conducting copper bar.
Preferably, the quantity of described water-stop tray is 3-8.
Preferably, each described water-stop tray is all perpendicular to the outer circumferential side layout of described seamless steel pipe, and the distance between adjacent described water-stop tray equates.
Preferably, described insulating packing is pitch.
Underground substation of the present utility model waterproof ground connection main line compatibly descends substation grounding to use, can meet larger earth current passes through, meet waterproof requirement, can better solve the problem that ground lead passes through the large base plate in underground substation, also can be used as a kind of product mass customized, in the time of casting underground substation large base plate as ground lead.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Brief description of the drawings
Fig. 1 is the structural representation of the underground substation waterproof ground connection main line of the present embodiment.
Fig. 2 is the schematic top plan view of Fig. 1.
Embodiment
As shown in the figure, the present embodiment proposes a kind of underground substation waterproof ground connection main line, comprise the conductor 100 for electric current being imported to grounding network cable, seamless steel pipe 200, insulating packing 300, nonmetal detent plug head 400 and water-stop tray 500, insulating packing 300 is filled in seamless steel pipe 200, two nonmetal detent plug head 400 correspondences are arranged on the both ends of seamless steel pipe 200, water-stop tray 500 windings are at seamless steel pipe 200 outer circumferential sides, nonmetal detent plug head offers the through hole wearing for conductor 100 in the axial direction, conductor 100 is located in seamless steel pipe 200 along extending axially of seamless steel pipe 200, and the both ends of the conductor 100 respectively through hole from nonmetal detent plug head 400 pass.
Concrete, the heavy cross section conducting copper bar that conductor 100 is 24mm for diameter, it is 1800mm that seamless steel pipe 200 adopts length, the seamless coating steel pipe that interior diameter is 80mm, insulating packing 300 is pitch, nonmetal detent plug head 400 adopts nylon material to make.The quantity of water-stop tray 500 is 5, and overall dimension is diameter 400mm, the round plate of thickness 5mm, each water-stop tray 500 is all arranged perpendicular to the outer circumferential side of seamless steel pipe 200, and between seamless steel pipe 200, be that seal welding is sheathed, the distance between adjacent water-stop tray 500 is equal, and spacing is 300mm.
Certainly, in other specific embodiments, conductor and insulating packing etc. can also adopt other suitable material to make as required, and the quantity of water-stop tray also can select other quantity such as 3 or 8 and other overall dimensions to make as required, repeats no more herein.
Exemplary, the applicable cases of the underground substation waterproof ground connection main line of the present embodiment on underground substation is as follows:
