Abstract
A kind of disc type synthetic insulator, structure comprises gold utensil bowl head, epoxy glass rod, metal pull bar, silicon rubber full skirt.Gold utensil bowl head is inserted in epoxy glass rod one end, and the other end inserts in metal pull bar, makes the rod metal pull bar crimping of gold utensil bowl headring oxygen glass and firmly links into an integrated entity, and silicon rubber full skirt is compounded in the periphery of epoxy glass rod.The utility model effect: one, be the creepage distance of enforced insulator; Two, be to make full use of the strong advantage of silicon rubber anti-pollution performance, make it to realize the transmission line moving all the year round and avoid cleaning; Three, being lightweight, is 30% of glass disc type insulation weight, is 50% of " porcelain core composite disk insulator " weight, and this,, for the height that reduces transmission line bar (tower), provides condition, can greatly save electrical network capital construction cost; Four, be " null value " problem of having stopped existing various " disk insulators " completely, got rid of a major break down hidden danger of electrical network.
Description
Technical field
The utility model relates to the suspension insulator within the scope of grid equipment, particularly relevant with UHV transmission line insulator to high pressure, superhigh pressure, specifically a kind of disc type synthetic insulator.
Background technology
Suspension insulator be send out, defeated, become the visual plant of electric power system, suspension insulator used on electrical network has: ceramic disk insulator, glass disk insulator, porcelain core disc type composite insulator and bar-shaped composite insulator string, electrical network operation for many years facts have proved, pottery and glass disk insulator all belong to hydrophily material, antifouling property is poor, to regularly clean, particularly DC power transmission line is more serious to the pollution of insulator.The workload of circuit operation maintenance is quite large.Bar-shaped composite insulator string, because silicon rubber material antifouling property is excellent, although overcome above-mentioned shortcoming, but for 220KV and above insulator string length all more than 2 meters, the particularly transmission line of 500KV and above, its length is more than 5 meters, transport and construction are all very inconvenient, and because oversize, the example of the sub-external insulation of Damage to insulation and interior insulation mandrel happens occasionally, hide some dangers for to the safe operation of electrical network.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned all kinds of insulators, provides one can meet the operation of electrical network long-term safety, can reduce again the disc type composite insulator of capital expenditure and the operating cost of power grid construction.
The technical solution of the utility model is achieved in that a kind of disc type composite insulator, it is characterized in that structure is gold utensil bowl head, silicon rubber full skirt, metal pull bar, epoxy glass rod four part compositions.Gold utensil bowl head is inserted in epoxy glass rod one end, the other end inserts in metal pull bar, make the rod metal pull bar crimping of gold utensil bowl headring oxygen glass and firmly link into an integrated entity, its structure height is consistent with the structure height of the disc insulator of national standard, and silicon rubber full skirt is compounded in the periphery of epoxy glass rod.Described silicon rubber full skirt establish 2 and more than.
The utility model is composite silicone rubber full skirt outside epoxy glass rod, to make full use of the resistant to pollution advantage of silicon rubber, make it to realize the transmission line moving all the year round and avoid cleaning, epoxy glass rod is core, one of its function is the weight that alleviates disk insulator, be conducive to greatly reduce the capital expenditure of power grid construction, two are " null value " problems of having eliminated operating insulator, three are the windage yaw problems that overcome bar type composite insulator string, the security reliability that improves electrical network, has significant economic benefit and social benefit.The utility model is applicable to friendship (directly) stream transmission line, power transformation and the power plant of 35KV-1000KV.
Brief description of the drawings
Fig. 1 is that the utility model silicon rubber full skirt is the structural representation of two.
Fig. 2 is that the utility model silicon rubber full skirt is the structural representation of three.
In figure: 1, gold utensil bowl head, 2, epoxy glass rod, 3, metal pull bar, 4, silicon rubber full skirt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated, the utility model is not limited to embodiment below.
Embodiment 1
As shown in Figure 1, 2, disc type synthetic insulator, its structure is gold utensil bowl 1, epoxy glass rod 2, metal pull bar 3, silicon rubber full skirt 4.Gold utensil bowls 1 are inserted in epoxy glass rod 2 one end, and the other end inserts in metal pull bar 3, make 1 epoxy glass rod 2 metal pull bar 3 crimping of gold utensil bowl and firmly link into an integrated entity, and its structure height is consistent with the structure height of the disc insulator of national standard.Silicon rubber full skirt 4 is compounded in the periphery of epoxy glass rod 2.Its silicon rubber full skirt establish 2 and more than.The silicon rubber full skirt 4 of epoxy glass rod 1 periphery is that high temperature is monolithic molding next time in sulfuration injection device.Epoxy glass rod 2 between gold utensil bowl 1 and metal pull bar 3 is high-strength insulating body, can bear high voltage and not breakdown, can bear very high mechanical pulling force, can meet the mechanical, electrical performance requirement of each step voltage transmission line safe operation completely.
Claims (2)
1. a disc type synthetic insulator, it is characterized in that being formed by gold utensil bowl head, silicon rubber full skirt, metal pull bar and epoxy glass rod, gold utensil bowl head is inserted in epoxy glass rod one end, the other end inserts in metal pull bar, make its gold utensil bowl headring oxygen glass rod metal pull bar crimping and firmly link into an integrated entity, its structure height is consistent with the structure height of the disc insulator of national standard, and silicon rubber full skirt is compounded in the periphery of epoxy glass rod.
2. disc type synthetic insulator according to claim 1, it is characterized in that described silicon rubber full skirt establish 2 and more than.
