Abstract
The utility model relates to a flange type installation window for fully embedded case type transformer substation, which consists of a window case and an upper casing. The utility model is characterized in that the rim of the upper casing is provided with a flange box made of angle steel. One inner circle of the flange box is provided with two loops of concentric steel bars. A sealing band is arranged between the steel bars and above the flange casing so to circumscribe the two steel bars. The window case is fixed with the flange box of the upper casing by a screw rod. Compared with traditional equipments, the utility model has the advantages of easy installation and maintenance of inner equipments for adopting separated flange connection. The special structure of the sealing band also improves general sealing property of the utility model.
Description
One, technical field
The utility model belongs to the equipment for power transmission and distribution field, and particularly a kind of box-type substation flange form that buries is entirely installed window.
Two, background technology
The installation window and the case body that bury box-type substation in the prior art entirely are the integral solder formulas, can not be split, and bring inconvenience therefore for the high-low pressure cabinet installation of transformer station inside and transformer maintenance.Owing to be that welded type connects, when having leakage weldering situation, the chance rain sealing problem of transformer station box will be particularly outstanding.
Three, summary of the invention
The utility model provides a kind of box-type substation flange form that buries entirely that window is installed at the problem of above-mentioned existence, on the flange frame on this window frame sealing strip is arranged, and has both made things convenient for the installation and maintenance operation of substation equipment, has solved the sealing problem of transformer station box again.
Technical solution of the present utility model is: a kind of box-type substation flange form that buries is entirely installed window, comprise window frame and upper ledge, the upper ledge periphery is provided with the flange frame that angle steel is made, the inboard circumferential edges of flange frame is provided with the concentric steel bar of two circles, accompany sealing strip between the steel bar, sealing strip is located on the flange frame and is circumscribed with two steel bars, and the flange frame on window frame and the upper ledge passes through bolt.The cross section of steel bar and sealing strip is circular, sealing strip is resilient, like this after installation, sealing strip is stressed because of compressing, the shape of cross section can be squeezed into ellipse by circle, meeting this moment behind the active force of both sides steel bar can further deformation again, is filled in the slit between steel bar and the upper and lower panel, increases the effective area of sealing function.There are not corner angle in the steel bar cross section after adopting circle, smoothly contacts with sealing strip, and sealing strip can not wear out impaired after repeatedly pushing because of stressed fatigue.
The utility model is compared with equipment in the past, owing to adopted split type flange to connect, installs and easier during maintenance casing internal unit, and the gasket structure of unique design also makes the overall sealing performance of equipment improve.
Four, description of drawings
Fig. 1 installs the structural representation of window for burying the box-type substation flange form entirely.(1) is upper ledge among the figure, and (2) are window frame, (3) flange frame, (4) steel bar, (5) sealing strip.
Fig. 2 is a flange frame structure vertical view.
Five, embodiment
A kind of box-type substation flange form that buries is entirely installed window, comprise window frame 2 and upper ledge 1, it is characterized in that upper ledge 1 periphery is provided with flange frame 3, flange frame 3 inboard circumferential edges are provided with the concentric steel bar 4 of two circles, accompany sealing strip 5 between the steel bar 4, sealing strip 5 is located on the flange frame and is circumscribed with two steel bars 4, and window frame 2 passes through bolt with flange frame 3 on the upper ledge 1.The cross-sectional area of steel bar 4 and sealing strip 5 is circular.
Claims (3)
1. one kind is buried box-type substation flange form installation window entirely, comprise window frame (2) and upper ledge (1), it is characterized in that upper ledge (1) periphery is provided with the flange frame (3) that angle steel is made, the inboard circumferential edges of flange frame (3) is provided with two circle concentric steel bars (4), accompany sealing strip (5) between the steel bar (4), it is last and circumscribed with two steel bars (4) that sealing strip (5) is located at flange frame (3), and the flange frame (3) on window frame (2) and the upper ledge (1) passes through bolt.
2. the box-type substation flange form that buries entirely as claimed in claim 1 is installed window, and the cross section that it is characterized in that sealing strip (5) is for circular.
3. the box-type substation flange form that buries entirely as claimed in claim 1 is installed window, and the cross-sectional area that it is characterized in that steel bar (4) is for circular.
