Abstract
The utility model in particular relates to a novel wall bushing, which belongs to the technical field of manufacturing the component of the high voltage switch cabinet. The novel wall bushing comprises a barrel body composed of an incoming barrel and an outgoing barrel, a dispersed skirt is arranged on the outer wall of the barrel body, a flange is externally arranged at the middle part of the barrel body, a knife bar is arranged on the inner wall, the barrel body, the dispersed skirt, the flange and the knife bar are integrally informed, and a shielding layer is fixedly arranged on the inner wall of the knife bar; inserting elements are arranged at four angles of the flange, the inserting elements are welded with a net circle through bar coppers, the net circle is embedded in the barrel body. The wall bushing of the utility model overcomes the defect in the prior art that the distribution of the electric field is not uniform through adding the shielding layer on the inner wall of the knife bar, so that the distribution of the electric field is uniform, therefore to prolong the service life; in addition, the net circle and bar coppers are embedded in the barrel body to reduce the partial discharge of an insulator, to further prolong the service life of the products.
Description
Technical field
The utility model belongs to the component manufacturing technology field of high-tension switch cabinet, particularly a kind of novel wall bushing.
Background technology
Usually, high-tension switch cabinet is made up of contact box, curved dividing plate and wall bushing, wall bushing is the requisite cashier's office in a shop element of high-voltage switch gear, be used between two switch cubicles, and be fixed on the cabinet plate, it connects the crucial effect of playing to busbar between high-tension switch cabinet, and the performance of wall bushing is also with the insulation property of direct high-tension switch cabinet and the security reliability of operation, thereby influences useful life.Present wall bushing comprises the cylindrical shell that constitutes by into and out of line tube one, and cylinder body outer wall is established diffusing skirt, cylindrical shell middle part peripheral hardware flange, inwall sets firmly blade row, bus row pass in the middle of blade row, and cylindrical shell, flange and blade row all adopt insulating material to make, the three in one moulding.But present wall bushing in use exists non-uniform electric, height is put in insulator office, causes product short defective in useful life.Therefore, need badly the structure of existing wall bushing is improved and innovated, overcome above-mentioned defective, to improve the useful life of product.
Summary of the invention
The utility model discloses a kind of novel wall bushing, solved present wall bushing and existed non-uniform electric, insulator office to put high technical problem.
For solving the problems of the technologies described above, technical solution adopted in the utility model: a kind of novel wall bushing, comprise the cylindrical shell that constitutes by wire feeding tube and output cylinder one, cylinder body outer wall is established diffusing skirt, cylindrical shell middle part peripheral hardware flange, inwall is established blade row, and cylindrical shell, diffusing skirt, flange and blade row are one-body molded, and the blade row inwall sets firmly screen; Flange is provided with inserts for four jiaos, and inserts is by a copper rod and a net circle welding, and the net circle is embedded in the cylindrical shell.
Described wall bushing, inserts has the hole, in the copper rod one termination patchhole; Described screen is the aluminium ring, and the net circle is made by stainless steel.
Wall bushing of the present utility model makes Electric Field Distribution even, thereby increases the service life by setting up the shortcoming that screen overcomes non-uniform electric in the prior art in the blade row inwall; Again, in cylindrical shell, imbed net circle and copper rod and reduce insulator office and put, further prolonged the useful life of product.

Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the structural representation of screen.
Fig. 4 is the structural representation of net circle.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Shown in Fig. 1,2,3,4, wall bushing comprises cylindrical shell, and cylindrical shell is made of wire feeding tube 1, output cylinder 9 one.Wire feeding tube 1, output cylinder 9 outer walls form the diffusing skirt 2 of symmetry.Cylindrical shell middle part peripheral hardware flange 3, inwall is established blade row 4, and cylindrical shell, flange 3 and blade row 4 all adopt epoxy resin to make, the three in one moulding.Blade row 4 inwalls fixedly install screen 6, and screen 6 is circular aluminium ring.Four jiaos of flange 3 respectively are provided with an inserts 7, have the hole on the inserts 7, in the brass bar 8 one end patchholes, and the other end and 5 welding of net circle, net circle 5 is a stainless (steel) wire, imbeds in the cylindrical shell.Inserts 7 also is provided with internal thread, when wall bushing is installed, is fixed in the installation site by bolt.
Claims (2)
1, a kind of novel wall bushing comprises the cylindrical shell that is made of wire feeding tube and output cylinder one, and cylinder body outer wall is established diffusing skirt, cylindrical shell middle part peripheral hardware flange, inwall is established blade row, and cylindrical shell, diffusing skirt, flange and blade row are one-body molded, and it is characterized in that: the blade row inwall sets firmly screen; Flange is provided with inserts for four jiaos, and inserts is by a copper rod and a net circle welding, and the net circle is embedded in the cylindrical shell.
