Existing common GIS housing mainly comprises cover plate, aluminum pipe, flange, bolt, first aluminium sheet is rolled into tubulose on veneer reeling machine when production and processing, and then carry out straight seam welding and obtain aluminum pipe, again and flange welding, flange is connected with cover plate by bolt the aluminum pipe processed, and centre adds sealing ring sealing gas, this structure welding procedure is complicated, weld seam is many, and gas leakage possibility is large, and processing cost is high.
Summary of the invention
For making up the deficiencies in the prior art, the invention provides a kind of shell structure simple, processing cost is low, convenient welding, the GIS housing of good airproof performance and processing technology thereof.
The present invention is achieved through the following technical solutions:
A kind of GIS housing, its special character is: comprise transverse tube and vertical tube, and the section of one end of described transverse tube and vertical tube be all 45 ° of tangent planes, and 45 ° of tangent planes of transverse tube and vertical tube are mutually identical to be connected and by being welded and fixed; The other end of described transverse tube and vertical tube respectively with Flange joint.
A kind of GIS housing of the present invention, described transverse tube and vertical tube all adopt one-body molded making, no-welding-seam on body, add housing seal intensity.
Further, a kind of GIS housing of the present invention, described transverse tube and vertical tube are the aluminum pipe that 8mm is thick.
The processing technology of a kind of GIS housing of the present invention, its special character is: comprise the following steps:
(1) select weldless two pipes of one-body molded body as transverse tube (1) and vertical tube (2), respectively one end of transverse tube (1) and vertical tube (2) is slit into 45° angle tangent plane (3);
(2) after transverse tube (1) being connected angle in 90 ° with vertical tube (2) one end in 45° angle tangent plane (3), seam welds is fixed;
(3) other end of transverse tube (1) and vertical tube (2) is welded with a flange (4) respectively.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the present invention adopts two integrated butt welding aluminium tubes to connect to form, and changes aluminum pipe in prior art and adopts the present situation of aluminium sheet processing, save labour cost and welding wire, eliminate the veneer reeling machine that original processing needs, reduce equipment cost, no-welding-seam on body, decreases the possibility of gas leakage.
(2) the present invention adopts two butt welding aluminium tubes to connect, and compares original aluminum pipe one end and adopts cover plate and flange seal, The present invention reduces the processing costs such as seal cover board, flange and encapsulation fitting thereof, avoids the poorly sealed situation that gas leakage occurs of seal cover board simultaneously.
(3) shell structure is simple, convenient welding, and cost is low, is suitable for the batch production of GIS engineering, in the cost-effective performance that improve product simultaneously, improves production efficiency, greatly improve the competitiveness in market.
(4) economize in raw materials compared with existing common GIS housing, housing can be saved cover plate weight and be about 17.5Kg(volume * density=[3.14* (565/2) 2mm*25mm) * 2.8]=17.5Kg), save flange weight and be about 4Kg({3.14* [(565-430/2) 2] * 2.8}=4Kg), use 1 threeway to calculate by each interval, annual 400 intervals and directly save material: aluminium 8600Kg, bolt 4800 overlaps, sealing ring 400, and welding wire workman man-hour etc.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is structural representations of existing GIS housing.
In figure, 1 transverse tube, 2 vertical tubes, 345 ° of tangent planes, 4 flanges, 11 cylindrical shells, 12 side neck bodies, 13 cover plates, 14 flanges, 15 bolts, 16 nuts, 17 sealing rings.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Accompanying drawing 2 is structural representations of existing GIS housing, comprise cylindrical shell 11, side neck body 12, cover plate 13, side neck body 12 is welded on cylindrical shell 11, the outer drain terminal of cylindrical shell 11 and side neck body 12 is all connected with flange 14, cover plate 13 is connected with the flange 14 of nut 16 with cylindrical shell 11 one end by bolt 15, cover plate 13 is provided with groove for installing sealing ring 17 sealing gas, cylindrical shell 11 and side neck body 12 are the aluminum tube that 8mm is thick, in processing and making process, first this aluminum tube is processed on veneer reeling machine by aluminium sheet, and then carries out straight seam welding and obtain aluminum tube.
