For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of post composite insulator is used the major diameter plug; It is characterized in that: comprise the interior plug and the enhancement layer that is arranged on interior plug outer surface of formed by extrusion and tension, said enhancement layer comprises along the hoop glass fabric layer of the interior plug hoop direction coiling and molding of the axial glass fabric layer of interior plug axis direction laying and edge.
Above-mentioned post composite insulator is used the major diameter plug, it is characterized in that: said axial glass fabric layer and hoop glass fabric layer are alternately setting.
Above-mentioned post composite insulator is used the major diameter plug, it is characterized in that: the quantity of said axial glass fabric layer and hoop glass fabric layer is multilayer.
Above-mentioned post composite insulator is used the major diameter plug, it is characterized in that: all be filled with epoxy resin in the hole of said axial glass fabric layer and hoop glass fabric layer.
Above-mentioned post composite insulator is used the major diameter plug, it is characterized in that: plug is the alkali-free glass fibre plug that is soaked with epoxy resin in said.
The utility model compared with prior art has the following advantages:
1, simple in structure, reasonable in design and use cost is low.
2, the utility model has less diameter under same rigidity, requirement of strength, less interface, and outer surface need not processing, not waste of material and environmental pollution, vacuum impregnation simultaneously has fabulous electrical strength.
3, owing to outer surface interval composite molding axial glass fabric layer and the hoop glass fabric layer of the utility model at interior plug; Therefore make that axial glass fabric layer and hoop glass fabric layer are bonding intact; No air gap, and then make product have higher machinery, electric property, intensity is high simultaneously; Good rigidly, in light weight.
4, the utility model can effectively be applicable to 220kV and the support of above AC system bus, isolating switch and direct current system smoothing reactor post composite insulator.
Through accompanying drawing and embodiment, the utility model is done further detailed description below.
