Description
Technical field
The utility model relates to a kind of compound seal insulator, belongs to outdoor Medium voltage switch or circuit breaker application.
Background technology
Outdoor sealing insulator is to be widely used in the crucial vigour part that FZW28 outdoor pole top switch connects galvanic circle and switch power set.The hermetically-sealed construction great majority of the most of insulators that exist are in the market integrated fixed sealing type sealing or only adopt the seal form of end face fit structure, insulation, the sealing reliability of the insulator of integral type sealing version are higher, but in assembling process, there is colliding with of certain probability unavoidably and produce and scrap, scrap disassembling of rear electric-conductor very difficult, affect follow-up production efficiency; And the another kind of insulator that only depends on end face seal structure, between pony insulator and insulating cylinder, there is no corresponding concentric fit, in assembling process, concentricity is difficult to ensure card, and then affect the effect of its end face seal, bury hidden danger to follow-up insulation, sealing property, As time goes on, very likely produce potential safety hazard.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of compound seal insulator, the insulator that has solved the integral type sealing version of scrapping is dismantled difficult problem, and the insulator concentricity that has simultaneously solved end face seal structure is difficult to ensure the problem of card.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of compound seal insulator, comprise conducting rod and insulating cylinder, one end of described conducting rod is provided with metal connecting sheet, the other end is provided with screw thread, on conducting rod between described metal connecting sheet and screw thread, be sealed with sheath, described sheath is provided with annular protrusion radially near the end of metal connecting sheet, described insulating cylinder is the tubular structure of hollow, described conducting rod arranges in the cavity of threaded one end embedding insulating cylinder, the end face of insulating cylinder abuts on the end face of annular protrusion, conducting rod is fixed by the clamp nut and the insulating cylinder that mate with screw thread, the contact position of described annular protrusion and insulating cylinder scribbles vacuum silicone grease, between described sheath and insulating cylinder cavity inner wall, be provided with sealing ring and gap scribbles vacuum silicone grease.
The casting integrated moulding of described metal connecting sheet and conducting rod; On described metal connecting sheet, have connecting hole.
Described annular protrusion and sheath integrated injection molding; Described annular protrusion is the cone of an axis centered by conducting rod.
Between described compression spiral shell and insulating cylinder, be also lined with pad.
Beneficial effect: 1, the utility model, by between sheath and insulating cylinder cavity inner wall, sealing ring being set, has been realized the location of conducting rod and the axial concentricity of insulating cylinder, has guaranteed concentricity; 2, sealing ring is combined in the contact position painting vacuum silicone grease of annular protrusion and insulating cylinder, and the gap between sheath and insulating cylinder cavity inner wall is coated with vacuum silicone grease, has guaranteed the sealing of insulator, can tolerate the gases at high pressure of 0.2Mpa through sealing experiment; 3, the utility model is fixed together conducting rod and insulating cylinder by clamp nut, easy removal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1: a kind of compound seal insulator, comprise conducting rod 1 and insulating cylinder 2, one end of described conducting rod 1 is provided with metal connecting sheet 5, on this metal connecting sheet 5 and the casting integrated moulding of conducting rod 1 and metal connecting sheet 5, have connecting hole, the other end of conducting rod 1 is provided with screw thread, on conducting rod 1 between described metal connecting sheet 5 and screw thread, be sealed with sheath 3, described sheath 3 is provided with annular protrusion 4 radially near the end of metal connecting sheet, annular protrusion 4 and sheath 3 integrated injection moldings, annular protrusion 4 is the cone of an axis centered by conducting rod 1, the tubular structure that described insulating cylinder 2 is hollow, described conducting rod 1 arranges in the cavity of threaded one end embedding insulating cylinder 2, the end face of insulating cylinder 2 abuts on the end face of annular protrusion 4, conducting rod 1 is fixing by the clamp nut 6 and the insulating cylinder 2 that mate with screw thread, compress between spiral shell 6 and insulating cylinder 2 and be also lined with pad 7, described annular protrusion 4 scribbles vacuum silicone grease with the contact position of insulating cylinder 2, between described sheath 3 and insulating cylinder 2 cavity inner walls, be provided with sealing ring 8 and gap scribbles vacuum silicone grease.
Above-described a kind of compound seal insulator when mounted, first by sheath 3 sealings on the conducting rod 1 between metal connecting sheet 5 and screw thread, on the end face of the annular protrusion 4 that will contact with insulating cylinder 2 and evenly coat vacuum silicone grease on sheath 3, firmly conducting rod 1 is embedded in insulating cylinder 2, until insulating cylinder 2 end faces and annular protrusion 4 end face laminatings, then rotation is more evenly distributed the vacuum silicone grease of contact position, finally at conducting rod 1, threaded one end is set and is inserted in pad and clamp nut 6, rotatably compress nut 6 and compress.
