Abstract
The utility model relates to a cable-through type pure-ceramic sleeve tube for partial discharge free transformers, which comprises a connecting terminal 1, a cable head 9, a flange 14 and a ceramic sleeve 11. The utility model is characterized in that the utility model also comprises a locating ring 16, a spring 17 and a clamping band 19, wherein the clamping band 19 is sheathed outside a cable 10; the locating ring 16 is connected with the tail end of the ceramic sleeve 11; the cable 10 is connected with the cable head 9 by passing through a gasket 18, the spring 17 and the locating ring 16; a semi-conducting glaze layer 12 is sintered between the lowest section ceramic umbrella of the ceramic sleeve 11 and ceramic sandstone 13. The utility model has the characteristics of favorable electric properties, convenient operation and low cost of the whole.
Description
Technical field
The utility model discussion be a kind of transformer outlet cable connector device, particularly a kind of 20kV-40kV wears the cable formula not to be had office and puts transformer true procelain sleeve pipe.
Background technology
At present, bushing shell for transformer for 20kV-40kV, when electric current in the 400A-1250A current range, general adopt worn cable structure more, be connected with the outside after promptly passing insulator with cable, at this moment, for the cable that guarantees to pass porcelain bushing has enough dielectric strengths between over the ground, all need insulate at cable outer wrapping crimped paper, its thickness is about 6mm, and this method is simple, practical, but because the outlet cable can arbitrarily move in porcelain bushing, the partial discharge performance is difficult to touch the mark, if moreover the transformer transportation time need pull down sleeve pipe, then fix and place all pretty troublesome for the cable that is enclosed with heavy insulation.
Summary of the invention
The technical problems to be solved in the utility model is to overcome in the prior art transformer terminal cable outlet at porcelain bushing domestic demand wrap insulate medium, and can arbitrarily move and influence the deficiency that performance is put in office, provide a kind of and promptly need not insulate by outsourcing crimped paper, can reach the transformer true procelain sleeve pipe that no office puts again.
Wearing the cable formula does not have office to put transformer true procelain sleeve pipe is improvements over the prior art, terminal cable is without the wrap insulate medium, solve the problems of the technologies described above with clip 19 and at the insulator surface of first segment porcelain umbrella lower part sintered semiconductor glaze with increasing spring 17: it comprises binding post 1, cable end 9, flange 14, insulator 11, it is characterized in that: also comprise a centring ring 16, spring 17, clip 19, outside the clip 19 cover cables 10, centring ring 16 is connected with the end of insulator 11, and cable 10 passes pad 18, spring 17, centring ring 16 and is connected with cable end 9; Sintering has semi-conducting glaze layer 12 between next the joint porcelain umbrella of insulator 11 and porcelain sand 13.Cable 10 adopts weldering or crimping with cable end 9.
The utility model is worn the cable formula not to be had office and puts transformer true procelain sleeve pipe and adopt spring 17 and clip 19 transformer outlet cable 10 to be fixed on the center of insulator 11, insulator between first segment porcelain umbrella and the porcelain sand surface sintering semi-conducting glaze layer 12, discharge water under the preceding proposition of flat＜5pC guaranteeing to reach office, the operation to outlet cable parcel has been cancelled in the inconvenience of dismounting again when promptly having solved the transformer transportation.It has good electric property, easy to operate, overall lower-cost characteristics.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
In conjunction with the accompanying drawings concrete enforcement of the present utility model is further described, flange is selected cast aluminium alloy for use, with cement glue 15 with flange 14 mucilage bindings on insulator 11, and use water curing, sintering layer of semiconductor glaze layer 12 between next the joint porcelain umbrella of insulator 11 and porcelain sand 13.By dimensional requirement clip 19 is enclosed within on the transformer outlet cable 10, and it is compressed with Crimping Pliers, overlap pad 18, spring 17 and the centring ring of making of insulating material 16, cable 10 is welded in the cable end 9, with cable end 9 wear back-up ring 8, square RunddichtringO 7, the below from insulator 11 penetrates again, from insulator 11 suitable for reading passing, cover square RunddichtringO 6, packing ring 5, D RunddichtringO 4, trim ring 3 on cable end 9,, binding post 1 is fixed on the cable end 9 gets final product at last cable end 9 and tight with nut 2.
