Abstract
The utility model relates to the antifouling apron cover of a disc suspended insulator for power lines, which is an antifouling protective device used for the disc suspended insulators of an overhead power line. The antifouling apron cover of a disc suspended insulator for power lines is approximate to a bowl shape, and is one-time compression injection molding by adopting the silicon rubber composite material as the main material. For installing the apron cover under the condition of not demounting the insulator strings in motion, one side of the apron cover is opened with a through slit whose connection mode adopts the mode of a connection piece and a nylon buckle being mutually combined or a staircase slit and the nylon buckle being mutually combined; the apron cover is sheathed on the insulator. The hydrophobic performance of the apron cover is utilized to prevent pollution; therefore, the flashover accident is prevented, and the safety of lines is enhanced.
Description
The utility model is a kind of anti-pollution protective device that is used for high voltage overhead power circuit cap and pin insulator, belongs to the technical field of power circuit external insulation.
Power overhead network generally all adopts disc suspension porcelain or glass fibre reinforced plastic insulating substring at present, and for high-tension overhead line insulation and fixing cord usefulness, this insulating method has used the time of last 100 years along Gong in this technical field.Yet in today of industry high speed development, the air-polluting degree grows with each passing day, and the insulator string that is used for power circuit is in this air, and its surface also will be polluted, thereby assemble salification part or other materials on its surface.On high-tension line, remove these polluter not a duck soups, not only time-consuming, take a lot of work, labour intensity is big, and is and abnormally dangerous.Because polluter accumulates in the surface of insulator, when air humidity is bigger, as greasy weather or mao mao's rainy day, surface at insulator will form water membrane, makes polluter form electric pathway together with moisture film on the surface of insulator, and at this moment the insulating effect of insulator is with destroyed, and generation flashover, cause the accident of power circuit, and can cause large-area power failure, worker, agricultural production are caused tremendous loss.The accident that causes owing to this class problem is recurrent, although the leakage distance that adopts the method that increases an insulator to increase insulator string is arranged at present, but because anti-pollution this root problem is not resolved, therefore it is of no avail that the method for employing increase insulator number is eliminated remaining of similar accident, can not reach its basic goal.
Goal of the invention of the present utility model is exactly that problem at above existence provides a kind of surface contamination and fog of preventing to build up into the power circuit cap and pin insulator antifouling apron of moisture film, and it can prevent the generation of surface contamination and flashover fault effectively.
Power circuit cap and pin insulator antifouling apron of the present utility model is seen on contour structures, formed by two parts, be bowl-type circular arc (1) part and hollow cylinder (2) part, these two parts structurally are that employing silicon rubber synthetic material is a material of main part, with injection-compression molding of method of pressure injection, and become as a whole.Hollow cylinder (2) is positioned at the central authorities of bowl-type circular arc (1) cylindrical, and the two is on the same axis.The shape of bowl-type circular arc is similar to the upper surface of cap and pin insulator, and its aspect ratio cap and pin insulator omits height a bit, and the internal diameter at its maximum open place is identical with the external diameter of cap and pin insulator.The internal diameter of hollow cylinder (2) part is identical with the external diameter of bowl head (7).During use, as long as this skirt cover directly is enclosed within on the disk-form insulator.
In the power circuit cap and pin insulator string in existing the use, under the situation of not dismantling insulator, add this skirt cover, therefore can have a straight joint (3), so that the straight joint both sides can separate, so that install in a side of skirt cover.Be provided with two row's nylon buckles (4) (every side one row) in the both sides of straight joint, in addition, also be provided with a slice brace (5) on straight joint, nylon buckles passes corresponding hole on the brace, and the both sides of skirt cover straight joint are connected to live.
In addition, on the mode that connects straight joint, also brace can be removed, and be stepped with straight joint processing or its cross section directly, therefore the both sides of its straight joint are respectively stairstepping, wherein be provided with row's nylon buckles on the ladder of one side, be provided with row's aperture (6) on corresponding position on the ladder of opposite side, nylon buckles passes aperture (6) and skirt is overlapped the straight joint both sides fixes.In use, this skirt cover is enclosed within on the insulator string gets final product.
Adopt the advantage of power circuit cap and pin insulator antifouling apron of the present utility model to be:
1. owing on cap and pin insulator, installed this skirt cover additional; not only protected insulator not contaminated; and because the hydrophobicity that this skirt cover is had; when its surface is subjected to polluting in air; the shape even the humidity of air reaches capacity; also can not form water membrane on its surface, and only can condense into the water polo shape, and the pollutant that it is surperficial is taken away in the process of drippage.Therefore the flashover fault that takes place owing to surface contamination can not take place, and has effectively improved the normal reliability of operation of power circuit.
2. the structure of this skirt cover is very simple, make also than being easier to, therefore its cost is not high, can be widely used on the cap and pin insulator of various high-voltage electric power circuits, on the basis that only increases some costs, make the fail safe of circuit operation significantly improve, prevent the damage of equipment and the accident of circuit,, increased this " skirt cover " from general effect, not only do not increase the total cost of facility, greatly reduce the total cost of facility on the contrary.
3. owing to the side at " skirt cover " has a straight joint, therefore be convenient in existing operating power circuit, under the situation of not dismantling the cap and pin insulator string, directly load onto this " skirt cover ", make construction simpler and more direct.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is the partly schematic cross-section separately time of stairstepping straight joint of the present utility model.
Fig. 4 is the scheme of installation of the utility model when combining with cap and pin insulator.Wherein (7) are the bowl heads of insulator, and (8) are the insulator porcelain patticoats, and (9) are the bulbs of insulator.
Embodiment of the present utility model is as follows:
" antifouling apron " adopts the silicon rubber synthetic material is material of main part, with injection-compression molding of method of pressure injection, and makes its one-tenth as a whole, and brace also adopts silicon rubber to form for the material of main part pressure injection.
In shape, require the inside of bowl-type circular arc portion can be close to the upper surface of cap and pin insulator, can not form big air gap, preventing to change the capacitance profile of insulator string, and destroy the Electric Field Distribution of bunch of insulator.
Installing, is example with the transmission line of 110KV and 220KV, puts this antifouling apron respectively on second insulator at its insulator string two ends, to cut off the flashover passage, improves its external insulation performance, prevents the generation of flashover fault.
According to the above, just can be made into power circuit cap and pin insulator antifouling apron of the present utility model.
