Abstract
A disc composite insulator structurally comprises a fitting socket, an epoxy glass fiber stick, a metal pull rod and a silicone rubber umbrella skirt. One end of the epoxy glass fiber stick is inserted into the fitting socket, the other end of the epoxy glass fiber stick is inserted into the metal pull rod, high pressure is applied to a fitting so that the fitting socket, the epoxy glass fiber stick and the metal pull rod are connected in a pressing mode to be firmly connected into a whole, and the silicon rubber umbrella skirt is composited on the periphery of the epoxy glass fiber stick. The disc composite insulator has the advantages that the creep age distance of the insulator is enlarged; the advantage that silicon rubber is strong in dirt resisting performance is fully used, and the effect that a power transmission line operates all the year round does not need to be cleaned; the weight is low, the weight of the disc composite insulator is 30 percent of the weight of a glass disc insulator and 50 percent of the weight of a porcelain core composite disc insulator, a condition is provided for reducing the height of a power transmission line pole (tower), and the capital construction cost of a power grid can be greatly saved; the problem of zero value of various existing disc insulators is completely solved, and large accidental hidden danger of the power grid is eliminated.
Description
Technical field
The present invention 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.
Content of the present invention
The object of the invention is the deficiency in order to overcome above-mentioned all kinds of insulators, provide 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.
Technical scheme of the present invention 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, and to gold utensil high-pressure power, 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 present invention 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 present invention 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 silicon rubber full skirt of the present invention is the structural representation of two.
Fig. 2 is that silicon rubber full skirt of the present invention 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 present invention is further described, the invention is not restricted to embodiment below.
Embodiment 1
As shown in Figure 1, 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, the other end inserts in metal pull bar 3, to gold utensil high-pressure power, make 1 epoxy glass rod 2 metal pull bar 3 crimping of gold utensil bowl and firmly link into an integrated entity, 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 is established 2.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.
Embodiment 2
As shown in Figure 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, the other end inserts in metal pull bar 3, to gold utensil high-pressure power, make 1 epoxy glass rod 2 metal pull bar 3 crimping of gold utensil bowl and firmly link into an integrated entity, 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 is established 3.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.
