Abstract
The utility model relates to a capacitor sleeve for an outdoor high-voltage breaker. The utility model is composed of a rain preventing hat 5, a sleeve tube 7, a conducting rod 1, a flange 8, and a sleeve tube core 9. The utility model is characterized in that the rain preventing hat 5 is molded by high-voltage electrical porcelain materials in a sintering manner; the lower end surface of the rain preventing hat 5 is provided with a circular groove. The utility model has the advantages of long creepage distance, freedom from moisture absorption and aging, uneasy dust contamination, favorable insulating performance, and reliable operation.
Description
The utility model relates to a kind of capacitance graded bushing that outdoor high voltage circuit breaker is used that is used for.
The capacitance graded bushing that traditional primary cut-out is used, its rainhat are to use the metalwork moulding, and the rubber parts structure that is connected sealing with other part is plate, and its weak point is that capacitance graded bushing two intermetallic creepage distances are short, thunder and lightning easily takes place puncture.And capacitance graded bushing easily goes into moisture or water, and dielectric loss is increased, and is difficult to guarantee conformance with standard in long-time running.
The purpose of this utility model just provide a kind of creepage distance big, nonhygroscopic, do not wear out, be difficult for being infected with dust, have the good insulation performance performance, operational reliability is high is used for the capacitance graded bushing that outdoor high voltage circuit breaker is used.
Solution of the present utility model is such: capacitance graded bushing adopts high tension insulator material sintering to form, its lower surface has the circle square groove, the seal washer pad is between rainhat and bushing insulator, be fixed with bowl-shape trim ring in the rainhat upper end, the creepage distance of capacitance graded bushing is to the aluminium flange, than the creepage distance increase of traditional capacitance sleeve pipe from trim ring.
Because rainhat of the present utility model makes with high tension insulator material sintering, creepage distance is big, thus its advantage be nonhygroscopic, do not wear out, be difficult for being infected with dust, have the good insulation performance performance, the operational reliability height.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation.
The utility model is to be made of rainhat 5, sleeve pipe 7, conducting rod 1, flange 8 and sleeving core 9, rainhat 5 usefulness high tension insulator material sinter moldings, its lower surface has the circle groove, between rainhat 5 and bushing insulator 7, be lined with seal washer 6, packing ring 6 has chimb, and the circle groove of chimb and rainhat 5 lower surfaces adapts.The bowl-shape trim ring 3 of taper is installed in rainhat 5 upper ends, the taper type of rubber washer 4 for adapting with it, rubber washer 4 endoporus are threaded, and the inner orifice lower edge is outstanding, makes it to adapt with rainhat 5 upper end inner orifice chamferings.When tightening the bowl-shape trim ring 3 of taper with nut, rubber washer 4 pressurizeds shrink to the axle center.Hold conducting rod 1 tightly.
In the present embodiment, the circle square groove opened of rainhat 5 lower surfaces and rainhat 5 are concentric circles.
