Detailed description of the invention
Below in conjunction with accompanying drawing 1, accompanying drawing 2 and embodiment, this utility model is further elaborated.
A kind of medium-tension bushing resistance test frock, including sleeve pipe 2, insulator foot 10, high tension generator 11, silicone rubber sleeve 1 is placed on insulator foot 10, sleeve pipe 2 is positioned in silicone rubber sleeve 1, the high-pressure side of high tension generator 11 is wired to the conduction copper rod 5 of sleeve pipe 2, and the ground terminal of high tension generator 11 is wired to the sensor connecting screw hole 4 of sleeve pipe 2.Silicone rubber sleeve 1 is cup-like structure, and wall of cup top is that cone-shaped coordinates with the seal groove 9 of sleeve pipe, and cone top can be with embedding sealing groove 9.The internal diameter of the silicone rubber inner chamber 6 of silicone rubber sleeve 1 is more than the external diameter of the epoxy resin cure layer 8 below sleeve pipe 2 seal groove 9.The central bore diameter of silicone rubber sleeve 1 is more than conduction copper rod 5 external diameter, less than the external diameter of the epoxy resin cure layer below sleeve pipe 2 seal groove 9.The distance at the top of the central bore of silicone rubber sleeve 1 to silicone rubber sleeve 1 top is identical with the height of the epoxy resin cure layer 8 below bobbin seal groove 9.
Embodiment 1:
As shown in Figure 1, insulator foot 10 10 silicone rubber sleeves 1 above line up 1 row at equal intervals, 1 sleeve pipe 2 is had above each silicone rubber sleeve 1, conduction copper rod 5 end face of sleeve pipe 2 has metal clip, metal clip afterbody has wired in series together, middle 4th or the 5th metal clip also has wire to be connected with the high-pressure side of high tension generator 11, and described wire is exceptionally straight, it is impossible to sagging and be more than 300 millimeters with insulator foot and ground distance.The sensor connecting screw hole 4 flexible conductive pin of interpolation of each sleeve pipe 2, elastic conduction contact pin afterbody is welded with wire the earth terminal conducting with high tension generator 11 that is cascaded.
As in figure 2 it is shown, silicone rubber sleeve 1 is obtained through mold hot solidification processing by electrically insulating silicone rubber, electrically insulating silicone rubber hardness 40 ± 5shA(Shore hardness).Silicone rubber sleeve 1 is cup-like structure, and wall of cup top is that cone-shaped coordinates with the seal groove 9 of sleeve pipe, wall of cup top end face internal diameter 71.6 millimeters, thickness 6.2 millimeters, wall of cup thickness 30 millimeters, and silicone rubber sleeve 1 is high 74.5 millimeters.The central bore diameter of silicone rubber sleeve 1 28 millimeters, central bore top end face and wall of cup top end face distance 53 millimeters.Conduction copper rod 5 external diameter 25 millimeters of sleeve pipe 2, long 176 millimeters.Sleeve pipe 2 seal groove 9 internal diameter 71.6 millimeters, groove width 6.2 millimeters.Sleeve pipe 2 seal groove end face is to lower section end face distance 53 millimeters.In order to improve the insulating properties of sleeve pipe, reducing partial discharge quantity, extend the service life of sleeve pipe, the two ends of the conduction copper rod 5 of sleeve pipe 2 are according to having 4 grooves at end face 10-13 millimeter.Conduction copper rod 5 is in addition to end face, and surface carries out blasting treatment and uses supersonic cleaning.After using above-mentioned measure, the conduction copper rod 5 of sleeve pipe 2 is tightr with the combination of epoxy resin, improves the insulating capacity of epoxy resin.Metal clip and elastic conduction contact pin is used to connect high-pressure side and earth terminal, it is achieved that quickly to connect, compared with bolts, saved the operating time.Electrically insulating silicone rubber hardness 40 ± 5shA(Shore hardness) selection solve the support problem of sleeve pipe, the impact when toughness of silicon rubber can be put into simultaneously with buffer ferrule, protect sleeve pipe.Silicone rubber sleeve 1 central bore outer shroud silicone rubber and wall of cup silicone rubber design with bobbin seal, it is to avoid the electric discharge problem between the end face of conduction copper rod 5 and sensor connecting screw hole 4.Simultaneously work as strengthening the effect of supporting sleeve.
