Abstract
The utility model discloses a composite porcelain insulator. The composite porcelain insulator comprises an insulator body. The composite porcelain insulator comprises an iron hat, a porcelain core, a composite silicone rubber coat and a steel pin. The composite porcelain insulator is characterized in that the porcelain core is a high-strength porcelain core, the iron hat, the high-strength porcelain core and the steel pin are fixedly mounted together through cement adhesive mutually, the composite silicone rubber coat is coated at a surface of the high-strength porcelain core. A firm pouring mounting structure which is at an end portion of the composite porcelain insulator and is for connecting a fitting with a porcelain core disc maintains stable and reliable mechanical pull strength of an original porcelain insulator; the composite silicone rubber coat is closely coated at a surface of the porcelain core disc by employing heat vulcanization one-step molding technology, so properties of excellent hydrophobicity, super strong anti-aging resistance, electric corrosion resistance capability and light weight are realized, moreover, a problem that a composite insulator can not be used in a tension string in a high voltage line in the prior art is solved.
Description
Technical field
The utility model belongs to the insulator field, specifically, relates to and a kind ofly is applicable to filthy regional rated voltage higher than 10KV, and frequency is no more than the interchange overhead transmission line of 50HZ and the porcelain composite insulator that transformer station uses.
Background technology
In the fast development of economic construction, today that atmosphere and environmental pollution are day by day serious, the version of existing insulator respectively has pluses and minuses.The good mechanical property of traditional porcelain and glass insulator, but under the condition of the humidities such as extraneous rain, dew, porcelain and glass insulator surface filth thing can form the moisture film that one deck has certain conductivity.If insulator is dirty more serious, insulator surface fully makes moist again, there will be stronger partial discharge phenomenon, easily causes power network line and equipment generation pollution flashover accident, and porcelain and glass insulator heavier, transportation and install inconvenient; The antifouling ability of composite insulator is good, lighter, but " brittle failure " accident of plug easily occurs bad mechanical property, so have the insulator product now, all is difficult to meet fully the requirement of electricity power engineering long-term safety reliability service.
Summary of the invention
The utility model has solved the pollution flashover problem of above-mentioned porcelain and glass insulator, common composite rod insulator " brittle failure " problem and composite insulator can not be for problems such as strain insulator-strings, a kind of fail safe is proposed, stability is strong, and it is very convenient to transport, install, cost is low, porcelain composite insulator applied widely.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of porcelain composite insulator, comprise insulator body, and described porcelain composite insulator comprises chapeau de fer, porcelain core, silicon rubber composite sheath and steel pin, it is characterized in that described porcelain core is high-strength porcelain core; Between described chapeau de fer, high-strength porcelain core and steel pin, by cement glue, be solidly installed, the silicon rubber composite sheath is coated on the surface of high-strength porcelain core.
The centre position, bottom of the recessed end of described high-strength porcelain core is provided with a pad.
Increased a concave groove on described chapeau de fer.
Is furnished with locking pin on described chapeau de fer.
Described chapeau de fer, steel pin all adopt the structure of suspension disc insulator.
Described silicon rubber composite sheath profile is umbrella shape.
The cluster parachute part lower surface of described silicon rubber composite sheath has been uniformly distributed some reinforcements.
The upper end of the lower end of described silicon rubber composite sheath and upper end gold utensil chapeau de fer and lower end gold utensil steel pin all is tightly connected.
Compared with prior art, the utility model has the advantage of:
1) plug of this porcelain composite insulator adopts high-strength ceramic, and mechanical tensile strength can reach the grade of porcelain and the glass insulator of same levels, has effectively solved plug " brittle failure " problem of common composite rod insulator.
2) end of this porcelain composite insulator connects the structure that gold utensil (steel pin, chapeau de fer) all adopts suspension disc insulator, and itself and high-strength porcelain core firmly water the shape structure, have kept the reliable and stable mechanical tensile strength of former porcelain composite insulator.
What 3) this porcelain composite insulator high-strength porcelain core used adopted the porcelain insulator maturation waters dress technique, adopts steel pin, chapeau de fer to connect, identical with the connecting mode of porcelain insulator, can be for strain insulator-string as the ordinary porcelain insulator.
4) this porcelain composite insulator adopts the heat cure one-shot forming technique tightly to coat one deck silicon rubber composite sheath in surface and the related interfaces of high-strength porcelain core, because the silicon rubber composite sheath has good hydrophobicity and the animal migration of hydrophobicity, thereby power frequency wet flash-over voltage and anti-soil sudden strain of a muscle ability have been improved.By artificial pollution flashover voltage contrast test, the porcelain insulator increase rate of the pollution flashover voltage ratio same type specification of every porcelain composite insulator is more than 70%.
5) the umbrella shape profile of described silicon rubber composite sheath has wind and rain self-cleaning ability preferably, and contamination speed is slow, and it is also very convenient that artificial water rinses and cleans, and particularly, in the dust-like filthy environment, more sees that it is excellent.This insulator is easily adjusted the external insulation creep distance simultaneously, can meet the requirement of Chong Wu district working line to the insulator string creepage distance.
6) the cluster parachute part lower surface of described silicon rubber composite sheath is uniformly distributed some reinforcements, in order to strengthen the intensity of gamp footpath product, in order to meet larger ice covering thickness requirement.
7) this porcelain compound inslation sub-surface has firmly coated the silicon rubber composite sheath, make it there is good shock-resistant ability, simultaneously because porcelain piece is not directly exposed in air, reduced that the porcelain piece caused because of circumstance of temperature difference cataclysm or thunderbolt punctures or the frequency of explosion, strengthened that it is anti-aging, the ability of anti-galvanic corrosion, thereby greatly reduced the line upkeep expense.
8) this porcelain composite insulator is lightweight, difficult broken, convenient transportation is installed and is safeguarded, its weight ratio porcelain insulator of the same type has alleviated 1/3, thereby reduced installation labour intensity and steel tower load-bearing pressure, what it can be good on strain insulator-string simultaneously bears bending moment and slows down the destruction of periodic shock power to steel tower.
9) this porcelain composite insulator contour structures is rationally unique, and its chapeau de fer has increased a concave groove on former porcelain insulator chapeau de fer basis, is convenient to this insulator tool using clamping while changing is installed.It is identical that insulator cap and steel pin connect size, structure height and former porcelain insulator, has good interchangeability, especially, on the circuit of existing operation, can directly change this composite insulator, and without former line-sag etc. is adjusted, it is very convenient to change.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
