Abstract
The utility model provides a disc-type insulator which includes a gold seat having an inner chamber with an opening groove, an external shed having an inner shed, a metal drawing rod connected with the external shed and having a first end embedded to and connected with the inner chamber of the gold seat, wherein the width B of the first end of the metal drawing rod arranged in the gold seat inner chamber is larger than the width b of the opening of the opening groove of the gold seat. The utility model can prevent the insulator from falling in a string, eliminate 'zero value', greatly reduce the weight, and realize free-of -maintenance operation. Furthermore, the utility model has a strong self-cleaning capability as well as strong resistance to damage from birds, ice flash and rain flash. Therefore, the construction investment and running cost of the electric network can be reduced while safety and reliability of the electric network can be improved.
Description
Technical field:
Disk insulator in the utility model and the electric power system transmission facility territory is relevant, and is particularly relevant with ultra high voltage suspension type shape disk insulator with high pressure, superhigh pressure.
Background technology:
Suspension insulator is the visual plant of electricity generation system and transmission system, in the electric power system at present there is used suspension insulator:
1, ceramic disc insulator:
2, glass boiler disc insulator:
3, bar type compound inslation substring.
Electric power system operation practice for many years shows that ceramic disc insulator shortcoming has: 1. fall string and happen occasionally; 2. it is poor that pottery belongs to the hydrophilic material antifouling property; 3. to regularly detect " null value " porcelain vase; 4. maintenance workload is big; 5. weight is big.
The shortcoming of glass fibre reinforced plastic insulating: 1. fiberglass is the same with pottery, belongs to hydrophilic material, and antifouling property is poor; 2. it is bigger regularly to clean maintenance workload; 3. heavy; 4. falling the string problem happens occasionally; 5. " null value " problem occurs in the blast mode.
Bar type compound inslation substring: all do not send out at 2 meters though there is the length of above-mentioned shortcoming 220KV and the above every string of bar type compound inslation, particularly 500KV and the every string length of above electric pressure are more than 5 meters, transportation and construction are all very inconvenient, and because oversize, the example of damage insulator external insulation and interior insulation (plug) happens occasionally, and stays hidden danger for the safe operation of electrical network.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of insulator of shutting out to fall the disk insulator of string.Another purpose of the present utility model is can eliminate " null value " in order to provide a kind of, weight reduction greatly, can realize non-maintaining, the ability that has very strong self-cleaning ability, anti-bird pest ability, anti-ice sudden strain of a muscle and rain to dodge, under the precondition of the security reliability that realizes the raising electrical network, reduce the capital expenditure of electrical network, reduce the disk insulator of the operating cost of electrical network.
The purpose of this utility model is achieved in that
The utility model disk insulator, include the gold utensil seat of the inner chamber of band open slot, the external shed of full skirt in the band, first end of the metal pull bar that is connected with external shed embeds in the gold utensil seat inner chamber and is connected with the gold utensil seat, it is characterized in that metal pull bar is positioned at the first end width B of gold utensil seat inner chamber greater than gold utensil seat open slot width of rebate b.
Between above-mentioned metal pull bar and gold utensil seat, have between metal pull bar and full skirt and metal pull bar, gold utensil seat, the compound insulation filling layer of full skirt.
Above-mentioned full skirt and insulation filling interlayer have the interface coupling layer.
Above-mentioned external shed surface tilt angle α=10～25 °.
Compare with traditional disk insulator, the utlity model has following advantage:
1), is embedded in the width of the width of metal pull bar first end in the gold utensil seat inner chamber, so stopped in transmission line, to fall the problem of string greater than gold utensil seat open slot notch;
2), the angle of inclination on external shed surface is big, is more than 2 times of traditional bar type composite insulator, has further improved the self-cleaning ability on full skirt surface;
3), the insulation filling layer between the gold utensil seat of metal pull bar and insulator can adopt the high strength glass fiber insulating material to make, and the variation of ambient temperature or vibration can not cause the insulation filling layer to crack the formula fragmentation, can stop the problem of " null value " insulator;
4), the inside and outside sudden strain of a muscle skirt of insulator can adopt silastic material, and weight reduces greatly, can realize non-maintaining;
5), this disk insulator adopts the combination of different disk tracks can realize anti-pollution flashover, anti-birds droppings evil, anti-icing sudden strain of a muscle, rainproof sudden strain of a muscle fully.
The utility model reduces the capital expenditure of electrical network under the precondition of the security reliability that realizes the raising electrical network, reduce the operating cost of electrical network.
Description of drawings:
Fig. 1 is real this usefulness new structure schematic diagram.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment:
Referring to Fig. 1, Fig. 2, the inner chamber 6 of band open slot 2 is arranged on the gold utensil seat 1, interior full skirt 3 adopts silastic material to make one with external shed 4.External shed surface tilt angle α=15 ° (also can between 10 °～25 °).First end 5 that is enclosed within metal pull bar 11 on the external shed embed in the gold utensil seat inner chambers and its width B greater than the width b of open slot notch.Metal pull bar second end 7 is the bulb shape.High strength glass fiber insulation filling layer 8 is arranged between gold utensil seat, full skirt and metal pull bar.The insulation filling layer is compound by interface coupling layer 9 and full skirt to be one.All-in-one-piece rubber seal 10 is with it arranged on full skirt.
Referring to Fig. 1, metal pull bar 11 first ends 5 embed in the gold utensil seat 1, under high pressure, insulation filling layer 8 is pressed between gold utensil seat 1 and metal pull bar first end 5, silicon rubber external shed 4 and interior full skirt 3 and silicone rubber O-ring 10 be at HTHP global formation next time, and be combined as a whole by interface coupling layer and insulation filling layer.In the application, can determine the polyphone sheet number of insulator according to different electric pressures, 35KV～the 750KV that adapts to power frequency ac voltage, and the transmission line of the 800KV of direct current, bearing pulling force is 70KN～530KN, its installation method and traditional disk insulator are identical.
