Abstract
The utility model discloses a kind of outdoor full-sealed transformer resin sleeve, comprise conducting rod, conducting rod is arranged with insulator, insulator is made up of mounting flange, multiple main insulation umbrella and secondary insulated umbrella from the bottom to top successively, described main insulation umbrella, secondary insulated umbrella are made up of epoxy resin composite material and are alternately arranged continuously, and the two ends of described conducting rod are connected to clamp nut; The groove of cutting off the water supply that cross section is arc-shaped is provided with in the lower disk surface of main insulation umbrella, secondary insulated umbrella.Beneficial effect is: have higher antifouling capacity and sealing property, can avoid producing leakage of oil because sealing rubber ring is aging; The total weight of sleeve pipe can be alleviated, improve the electric property and mechanical performance and operation power reliability that insulate; Effectively can block the current flowed down by the disk upper surface of main insulation umbrella and secondary insulated umbrella, block-water effect is good.
Description
Technical field
The utility model relates to a kind of bushing shell for transformer being applied to high voltage power transmission and transforming system, particularly the outdoor full-sealed transformer resin sleeve of one.
Background technology
At present, domestic outdoor full-sealed transformer sleeve pipe multiplex industry pottery magnetic combines with metal conducting bar, forms by seal with elastometic washer.Can there is oil seepage phenomena because rubber ring is aging in this sleeve pipe, thus affect the safe operation of transformer and cause environmental pollution in the long-time running of oil-immersed type transformer, causes very large difficulty to the maintenance of electricity consumption department to transformer.
Utility model content
Technical problem to be solved in the utility model is to provide one and eliminates sealing rubber ring, can avoid producing leakage of oil because sealing rubber ring is aging, the outdoor full-sealed transformer resin sleeve that block-water effect is good.
For solving the problem, the utility model adopts following technical scheme:
A kind of outdoor full-sealed transformer resin sleeve, comprise conducting rod, its special character is: on conducting rod, be arranged with insulator, insulator is made up of mounting flange, multiple main insulation umbrella and secondary insulated umbrella from the bottom to top successively, described main insulation umbrella, secondary insulated umbrella are made up of epoxy resin composite material and are alternately arranged continuously, and the two ends of described conducting rod are connected to clamp nut; The groove of cutting off the water supply that cross section is arc-shaped is provided with in the lower disk surface of main insulation umbrella, secondary insulated umbrella.
Preferably, the horizontal tilt angle b of groove both sides tangent line of cutting off the water supply described in is 10 ~ 15 °.
Preferably, the disk upper surface of described main insulation umbrella, secondary insulated umbrella is downward-sloping taper seat and angle of inclination a is 10 ~ 15 °.
Preferably, described mounting flange is that epoxy resin composite material is made and is cast into one with main insulation umbrella and secondary insulated umbrella.
Preferably, the quantity of described main insulation umbrella is four, and the quantity of secondary insulated umbrella is three.
The beneficial effects of the utility model are:
1, because main insulation umbrella, secondary insulated umbrella are made up of epoxy resin composite material, and epoxy resin composite material has good hydrophobicity, thus make this sleeve pipe have higher antifouling capacity and sealing property, therefore eliminate the sealing rubber ring of traditional transformer sleeve pipe, can avoid producing leakage of oil because sealing rubber ring is aging.
2, because main insulation umbrella, secondary insulated umbrella are made up of epoxy resin composite material, epoxy resin composite material sleeve pipe can reduce than similar sleeve pipe porcelain insulating product height, in addition, epoxy resin composite material proportion is also less than electroporcelain material, thus the total weight of sleeve pipe can be alleviated, therefore can improve electric property and the mechanical performance of insulation, and operation power reliability can be improved.
3, owing to being provided with in the lower disk surface of main insulation umbrella, secondary insulated umbrella the groove of cutting off the water supply that cross section is arc-shaped, effectively can block the current flowed down by the disk upper surface of main insulation umbrella and secondary insulated umbrella, block-water effect is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-main insulation umbrella, the secondary insulated umbrella of 2-, 3-conducting rod, 4-mounting flange, 5-clamp nut, 6-cuts off the water supply groove.
Embodiment
As shown in Figure 1, the outdoor full-sealed transformer resin sleeve of the one that the utility model relates to, comprise conducting rod 3, conducting rod 3 is hollow ladder shaft-like, conducting rod 3 is arranged with insulator, the integrative-structure that described insulator is cast by mounting flange 4, multiple main insulation umbrella 1 and secondary insulated umbrella 2 from the bottom to top successively, described main insulation umbrella 1, secondary insulated umbrella 2 and mounting flange 4 are epoxy resin composite material and make, and described multiple main insulation umbrella 1 and secondary insulated umbrella 2 are alternately arranged continuously.The two ends of described conducting rod 3 are provided with external screw thread and are connected to two clamp nuts 5.The quantity of described main insulation umbrella 1 and secondary insulated umbrella 2 is determined according to the size of creepage distance, when creepage distance increases, and the increasing number of required main insulation umbrella 1 and secondary insulated umbrella 2.In the present embodiment, the quantity of described main insulation umbrella 1 is for four, and the quantity of secondary insulated umbrella 2 is for three.
The disk upper surface of described main insulation umbrella 1, secondary insulated umbrella 2 is downward-sloping taper seat and angle of inclination a is 10 ~ 15 °, be provided with in the lower disk surface of main insulation umbrella 1, secondary insulated umbrella 2 groove 6 of cutting off the water supply that cross section is arc-shaped, the tangent line horizontal tilt angle b of groove 6 both sides of cutting off the water supply is 10 ~ 15 °.As preferably, the angle of inclination a of described main insulation umbrella 1, secondary insulated umbrella 2 is 15 °, and the angle of inclination b of groove 6 both sides of cutting off the water supply is 10 °.The current flowed down by the disk upper surface of main insulation umbrella 1 and secondary insulated umbrella 2 effectively can be blocked by groove 6 of cutting off the water supply.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification and execution mode utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
