The utility model relates to the outlet sleeve pipe of the various device (as transformer, circuit breaker etc.) of a kind of 35kv of being used for and above electric pressure, and can be used as the wall bushing in the transformer station.
Used outlet sleeve pipe is oil-impregnated paper insulation condenser type outlet sleeve pipe, its structure as shown in Figure 1, its outermost is two relative by the made inside and outside sheath 1,2 of ceramic material, wherein: inner sheath is located at the bottom (indoor side) of outlet sleeve pipe; Oversheath is located at the top (outdoor side) of outlet sleeve pipe, between the inside and outside sheath 1,2 is flange 3, its center is a threading conduit 4, at inside and outside sheath 1,2, and be capacitance type structure 5 between the conduit, inside and outside sheath 1,2 and 5 of capacitance type structures are perfused with insulating oil 6, its lower end is a grading shield 7 in the oil, the device interior wiring penetrates threading conduit 4 by this grading shield 7, and its top is provided with conservator 8, is the outlet termination 9 with equal laminated structure above the conservator 8.The insulating oil of some is housed in the conservator 8, and the capacitance type structure 5 in conservator 8 and the sheath passes to mutually and guarantees to be full of insulating oil in the capacitance type structure 5.Above-mentioned inside and outside sheath 1,2, flange 3, grading shield 7, conservator 8 and the outlet termination 9 with equal laminated structure are by being located at the helicitic texture fit sealing at conduit two ends.There is following disadvantage in the outlet sleeve pipe of on-the-spot this kind of operation reflection structure:
1, seepage oil, because the many places faying face is the rigidity combination, sealing is poor, and insulating oil (as the transformer wet goods) permeates the very capable of small gap, therefore is difficult to guarantee non-leakage oil.
2, because sealing is bad, causing insulate makes moist, and the dielectric loss that shows as main insulation and end screen insulation against ground increases.
3, maintenance workload is big, the oil sampling check that will internally fill every year, and check oil level, repairing.
4, around oil and oil-impregnated paper insulation, be rigid material, the danger of blast on fire is arranged.
Summary of the invention
Technical problem to be solved in the utility model is at the above-mentioned deficiency of prior art, and to provide the dry-type high-voltage equipment outlet sleeve pipe that a kind of maintenance workload is little, do not have seepage oil and explosion hazard.
Above-mentioned technical problem of the present utility model is realized by following technical scheme.
A kind of dry-type high-voltage equipment outlet sleeve pipe, comprise: inside and outside sheath, be located at flange between two sheaths, at the threading conduit at center and the capacitance type structure between inside and outside sheath and the conduit, its lower end is a grading shield, and its top is the outlet termination with equal laminated structure, it is characterized in that:
Above-mentioned oversheath is the adapter sleeve of plastic material; Be filled with the insulation ointment between inner sheath and the capacitance type structure.
Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:
This adapter sleeve is a heat-shrinkable T bush.
Adapter sleeve and inner sheath are made by plastic material.
This inner sheath is made by ceramic material.
The outside of adapter sleeve is with the full skirt of plastic material;
Adapter sleeve and overcoat full skirt are one-time formed adapter sleeves with full skirt.
In the both ends or one end of conduit, the inner face of capacitance type structure is provided with the anti-sliding sleeve of inverted cone shape.
This capacitance type structure is a multi-segment structure, and every section outside all is surrounded by the adapter sleeve that heat-shrinkable T bush is made, and every section the last layer capacitance screen is connected by conduction or semiconductive material on electric with the first screen of hypomere.
Advantage of the present utility model is:
1, its inside filling liquid oil not, so the problem of ne-leakage oil;
2, be full of the insulation ointment between inner sheath and the capacitance type structure, no air gap guarantees dielectric strength;
3, maintenance workload is little, does not have the problem of sampling check oil, oil level and repairing.
4, in the periphery of capacitance type structure and under-filled insulation ointment, its upper outside is a nonrigid material, and selected material is fire proofing, can not take place or because of the blast that causes on fire.
For structure of the present utility model, feature and function thereof are had further understanding, enumerate specific embodiment now and be described with reference to the accompanying drawings as follows:
Description of drawings
Fig. 1 is the structure chart of the oil-impregnated paper insulation condenser type outlet sleeve pipe of prior art.
Fig. 2 is the structure chart of dry-type high-voltage equipment outlet sleeve pipe of the present utility model.
Embodiment
Shown in Figure 2, be a kind of dry-type high-voltage equipment outlet sleeve pipe provided by the utility model.This outlet sleeve pipe comprises: inner sheath 1, oversheath 2, be located at the flange 3 of 1,2 of inside and outside sheaths, at the threading conduit 4 at center and the capacitance type structure 5 between inside and outside sheath 1,2 and the conduit 4, its lower end is a grading shield 7, the device interior wiring penetrates threading conduit 4 thus, its top is the outlet termination 9 with equal laminated structure, for back panel wiring; Wherein:
