Abstract
The utility model relates to a top mounting type wall feed-through sleeve and is used for realizing the sealing problem of the wall feed-through sleeve. The top mounting type wall feed-through sleeve structurally comprises a conducting rod, a metal accessory, a porcelain bushing and a mounting flange and is characterized in that the mounting flange is in a two-symmetrical-part butt joint structure, the junction part of two part butt joint surfaces is provided with a center sealing groove, and an annular sealing groove is arranged at a position in a joint surface of a top surface welding plate of a mounting base and the bottom surface of the installing flange. The top mounting type wall feed-through sleeve has the advantages that a center sealing structure of a butt joint flange can prevent rain from entering a base object from the flange butt joint surface, the step-shaped sealing structure arranged between the top surface welding plate of the base object and the sealing groove of the flange bottom surface can prevent rain on the top surface of the base object from entering the sleeve from the flange bottom surface, the double-side sealing effect is reached, and the problems of water leakage and rain leakage of the top mounting type wall feed-through sleeve are solved.
Description
Technical field
The utility model relates to a kind of insulating sleeve, is particularly useful for roof-mounted wall bushing, belongs to the electric component technical field.
Background technology
Insulating sleeve is called for short sleeve pipe, and according to the GB/T 4109-2008 definition of " alternating voltage is higher than the insulating sleeve of 1000V ", sleeve pipe is that one or several conductor of confession under directions passes such as partitions such as wall or casings, plays the device of support and insulating effect.Insulating sleeve is applicable to power station and electric substation's power distribution equipment and High-Voltage Electrical Appliances, supplies lead to pass ground dummy board, wall or electrical equipment shell, supports current-carrying part to make it over the ground or casing insulation.Insulating sleeve can be divided into single insulating sleeve pipe, compound insulating sleeve and condenser-type terminal by insulation system.
The single insulating sleeve pipe with true procelain or insulation resin, is often processed wall bushing, is used for the distribution facility of 35kV and following electric pressure.Existing wall bushing generally is assembled by porcelain spare, conducting rod, two ends metal-ware and mounting flange, in the middle of porcelain spare, clamps or the mucilage binding mounting flange, and the two ends metal-ware is fixed on conducting rod on the sleeve pipe vertical center line.The wall bushing of this structure; To different installation bases; Generally mounting flange is made size and the symmetric shape that the basis coupling is installed, solve the installation question of horizontal wall bushing so well, but for the dress wall bushing of top; Because mounting flange two symmetric part interfaces and flange are bad with the basic top seal effect of installation, the generation of the phenomenon that very easily causes leaking, leak.
The utility model content
The purpose of the utility model is the drawback to prior art, provides a kind of simple in structure, safe and reliable, can significantly improve flange and the roof-mounted wall bushing that basic top seal performance is installed.
The said problem of the utility model realizes with following technical proposals:
A kind of roof-mounted wall bushing; Comprise conducting rod, metal-ware, insulator and mounting flange in the formation; Its special feature is: said mounting flange is two symmetric part docking structures; Intersection at two parts interface is provided with the central seal groove, with the place, end face weldering plate composition surface that the basis is installed circular seal groove is set in the mounting flange bottom surface.
Above-mentioned roof-mounted wall bushing installs sealing gasket additional in the central seal groove of mounting flange interface intersection setting.
Above-mentioned roof-mounted wall bushing is located to install sealing ring additional in the circular seal groove in mounting flange bottom surface and end face weldering plate composition surface.
The abutted flange central seal structure of the utility model can stop rainwater to get into basic thing from the flange interface; Install the stepped hermetically-sealed construction that sealing ring forms additional between the seal groove of flange bottom surface and basic thing end face weldering plate; Can stop the rainwater of basic thing end face to get into along the flange bottom surface; Reach the effect of dual face seals, solved the leaking of top dress wall bushing, roof leaking problem.

Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5; The utility model comprises conducting rod 1, metal-ware 2, insulator 3 and mounting flange 4 in constituting; Its special feature is: said mounting flange 4 is two symmetric part docking structures; Intersection at two parts interface 4-2 is provided with central seal groove 4-4, and 4-1 is provided with circular seal groove 4-3 with the place, end face weldering plate 5 composition surfaces that the basis is installed in the mounting flange bottom surface.
Referring to Fig. 7, the utility model installs sealing gasket 6 additional in the central seal groove 4-4 of mounting flange interface intersection setting.
Referring to Fig. 7, the utility model is located to install sealing ring 7 additional in the circular seal groove 4-3 in mounting flange bottom surface and end face weldering plate composition surface.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, the operation principle of the utility model is:
In the mounting flange of docking structure, add central seal groove 4-4 design; And adding sealing gasket 6; Can strengthen the seal degree of mounting flange two symmetric part interfaces like this, prevent that things such as rainwater from getting into the basic thing from the flange interface, strengthened the sealing of sleeve pipe.
4-1 is provided with circular seal groove 4-3 in the mounting flange bottom surface; With its interface end face weldering plate 5 on also be provided with the circular ring type seal groove; Heart folder sealing ring 7 therein after two parts butt joints; Can form stepped insulating course, prevent that rainwater from getting into the basic thing in the gap between top weldering plate and flange, strengthen the sealing that sleeve pipe is installed.
The hermetically-sealed construction of the utility model is specially adapted to push up the wall bushing of dress.
