Abstract
The utility model discloses a canned type air insulation goes out wire sleeve, including the flange with be located the sleeve pipe and the full skirt of flange both sides respectively, all there is the alloy inserts in the insulating main part at sleeve pipe and full skirt place, has the shield ring inside the flange, the flange has the seal groove in the one side towards the full skirt, has the sealing washer in this seal groove, the flange has location step towards sheathed tube one side. Improve the full skirt, increased creepage distance, use through seal groove and sealing washer cooperation, solve sealed problem.
Description
Technical field
The utility model relates to grid equipment connector field, particularly relates to closed type air insulation outlet casing tube.
Background technology
The outlet casing tube of gas filled switchgear is mainly the European sleeve pipe of standard in the market, for in SF6 dielectric, sleeve pipe one end is the European structure of standard, and other end creepage distance is about 130mm, when meeting creepage distance requirement for during environment-friendly type gaseous environment; Though and for the outlet casing tube of air-insulated open switch equipment with full skirt, but because the reason of environment for use does not have seal groove, the mode of the additional silicon rubber umbrella skirt cover of common European outlet casing tube is from principle, introduce a new medium, add an interface, thus bring series of problems, and as: interfacial pressure, silicon rubber are aging, bubble-discharge etc., add risk.
Utility model content
The purpose of this utility model is a kind of closed type air insulation outlet casing tube, improves full skirt, adds creepage distance, by seal groove and sealing ring with the use of, solve sealing problem.
The technical solution of the utility model is a kind of closed type air insulation outlet casing tube, comprise flange and the sleeve pipe and the full skirt that lay respectively at flange both sides, alloy inserts is had in the insulating body at described sleeve pipe and full skirt place, there is shading ring flange inside, described flange is having seal groove towards the side of full skirt, has sealing ring in sealing groove; Flange has positioning step towards the side of sleeve pipe.
Further, described positioning step has 3, and the angle between two adjacent positioning steps is 120 °, the wide 15mm of positioning step, and thick is 4mm.
Further, full skirt one has 5, adjacent full skirt spacing 20cm, and the height of full skirt is 15mm.
Further, the width of seal groove is 4mm, and the degree of depth is 2mm, and sealing ring is O type.
Further, there is the leading-out terminal of shading ring on the surface of flange, and this leading-out terminal and nearest positioning step stagger 60 °
Beneficial effect: by increasing the mode of the full skirt of specific aligned transfer, add creepage distance, solve the not enough problem of existing outlet casing tube creepage distance in environmental protection gas, simultaneously, full skirt and insulating body are that epoxy resin is one-body molded, there is not the interface problem that parcel silicone rubber sleeve brings, under the trend greatly developing environmental protection intelligent grid at present, can well apply to environmental-protective gas-insulating metal enclosed switchgear; By increasing seal groove, O RunddichtringO is coordinated to solve sealing problem; Design Orientation step on non-tight face, can prevent bilateral sleeve pipe in installation process from following screw and rotate, can also play the effect of location, makes immediately below shading ring leading-out terminal aims at all the time, to be convenient to draw ground connection.

Mark in figure: 1-flange; 2-sleeve pipe; 3-full skirt; 4-seal groove; 5-sealing ring; 6-positioning step; 7-gas tank wall; 8-sleeve pipe pressing plate.
Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail:
Composition graphs 1, Fig. 1 is the mounting structure figure of closed type air insulation outlet casing tube.Sleeve pipe 2 and full skirt 3 lay respectively at the both sides of circular flange 1, and there is alloy inserts insulating body and sleeve pipe 2 inside at described full skirt 3 place.Described full skirt 3 has 5, adjacent full skirt 3 spacing 20cm, and the height of full skirt 3 is 15mm, and creepage distance is 200mm.Flange 1 has seal groove 4 towards the side of full skirt 3, and the width of seal groove 4 is 4mm, and the degree of depth is 2mm, has O RunddichtringO 5 in seal groove 4.Described flange 1 has 3 positioning steps 6 towards the side of sleeve pipe 2, and the angle between two adjacent positioning steps 6 is 120 °, the wide 15mm of positioning step 6, and thick is 4mm.There is shading ring flange 1 inside.There is the leading-out terminal of shading ring on the surface of flange 1, and this leading-out terminal and nearest positioning step 6 stagger 60 °, and described leading-out terminal down.
Composition graphs 1 and Fig. 2, Fig. 2 are the mounting structure figure that closed type air insulation outlet casing tube is installed to gas tank.First smear fluid sealant by sealing ring 5 during installation, sealing ring 5 is being put in seal groove 4.Closed type air insulation outlet casing tube is injected the circular hole on gas tank wall 7, and full skirt 3 is positioned at gas tank inside, and flange 1 and sleeve pipe 2 are positioned at gas tank outside, and sealing ring 5 is close to outside gas tank wall 7.Sleeve pipe pressing plate 8 is through sleeve pipe 2, and push down flange 1, positioning step 6 exposes, and the recess on sleeve pressing plate 8 blocks, and prevents closed type air insulation outlet casing tube from rotating when mounted, directly over one of them positioning step 6 is positioned at, immediately below leading-out terminal is positioned at.
3 closed type air insulation outlet casing tubes are arranged side by side, and sleeve pipe pressing plate 8 is fixed on gas tank wall 7 side by bolt, and sealing ring 5 is close to outside gas tank wall 7, are conducive to gas tank sealing.3 closed type air insulation outlet casing tubes fixed by one piece of sleeve pipe pressing plate 8 simultaneously.Full skirt 3 and insulating body are that epoxy resin is one-body molded, there is not the interface problem that parcel silicone rubber sleeve brings, under the trend greatly developing environmental protection intelligent grid at present, can well apply to environmental-protective gas-insulating metal enclosed switchgear.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
