Abstract
The invention relates to a hollow pillar composite insulator with the creepage distance of the inner wall increasing, which consists of an upper metal accessory 1, a lower metal accessory 5, an epoxy resin glass fiber hollow tube 3 and a silicone rubber flared skirt 2. The hollow tube 3 is provided with creepage distance increasing sections 4 which are used for increasing the creepage distance of the inner wall of the hollow tube. The heights of the creepage distance increasing sections and the spacing between two adjacent creepage distance increasing sections can be calculated according to requirements for the specific distance for creepage of the inner wall. The surfaces of the inner wall of the hollow tube and the creepage distance increasing sections are coated with RTV, thereby preventing the epoxy tube from absorbing moisture, improving the electrical performance and avoiding the creeping discharge of the inner wall during condensation.
Description
Technical field
The present invention relates to the post composite insulator of a kind of 220kv and above electric pressure.
Background technology
Existing high-voltage strut composite insulator is to bear mechanical load with the epoxy resin fiberglass leading-drawing rod as supporter.Owing to be subjected to the restriction of production technology, can only produce the following leading-drawing rod of Φ 120mm at present both at home and abroad, can not satisfy the required post composite insulator requirement of mechanical strength of 220kv and above electric pressure.The plug of now producing 220kv and above post composite insulator mainly contains three kinds of patterns: 1. with the porcelain rod as plug.Yielding in the major diameter porcelain rod sintering procedure, sintering is inhomogeneous, and rate of finished products is low, energy consumption is big, and porcelain core rod shock resistance is poor, and weight is big; 2. twine epoxy resin fiberglass and make large diameter solid bar outside leading-drawing rod, this major diameter plug will divide the multi-lay winding moulding, and the interlayer bonding interface easily forms air gap, and the expense material of taking a lot of work, and cost is higher.With the epoxy resin fiberglass pipe of filling insulating gas as plug.This insulator of inflating in hollow pipe has the anxiety of gas leakage, and in service must regularly the detection increased maintenance workload.Therefore, all there is certain defective in the post composite insulator of making of above-mentioned three kinds of plugs.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of good electric property, mechanical strength height, exempt from inflation, lightweight hollow pillar composite insulator with creepage distance of inner wall increasing.
Hollow pillar composite insulator with creepage distance of inner wall increasing is made of upper and lower metal-ware 1,5 and epoxy resin fiberglass hollow pipe 3 and silicon rubber full skirt 2.Hollow pipe 3 has to increase climbs joint 4.Increasing the effect of climbing joint 4 is the creepage distances that increase the hollow pipe inwall.Increasing height and two adjacent distances of climbing joint that increase of climbing joint can calculate definite according to the requirement of creepageization of inwall distance＞15mm/kv.The hollow pipe inwall is climbed joint surface spraying RTV with increasing, and stops the epoxy tube moisture absorption, improves electric property, inwall creeping discharge when preventing condensation.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Specific implementation method
With reference to accompanying drawing, make hollow pillar composite insulator with creepage distance of inner wall increasing in the following order:
1. increase with Mold Making epoxy resin and climb joint 2 and bushing pipe, and climb joint surface spraying RTV with increasing at the bushing pipe inwall;
2. will increase the bushing pipe of climbing joint 2 and brachymemma and be sleeved on piecemeal on the Steel pipe mould, sand papering is used on the surface, and with behind the acetone cleaning, drying, places and twine epoxy resin fiberglass on the wrapping machine, makes it reach designed thickness.In baking oven after the heating cure, last lathe machine-shaping;
3. increased the interior sulphurated siliastic full skirt 2 of mould that the hollow pipe 3 of climbing joint 4 places the production composite insulator above-mentioned having of processing;
4. in constant-temperature constant-humidity environment, assemble two ends metal-ware 1,5.
Claims (3)
1. hollow pillar composite insulator with creepage distance of inner wall increasing is characterized in that post composite insulator increases the epoxy resin fiberglass hollow pipe (3) and the silicon rubber full skirt (2) of climbing joint (4) by upper and lower metal-ware (1,5), inner wall belt and constitutes.
2. hollow pillar composite insulator with creepage distance of inner wall increasing according to claim 1, the inwall that it is characterized in that bearing the epoxy resin fiberglass hollow pipe (3) of mechanical load has to increase climbs joint (4).Increasing the effect of climbing joint (4) is the creepage distance that improves inwall.
3. increase according to claim 1 and 2 described inwalls and climb the t shore composite insulator, it is characterized in that the inwall of epoxy resin fiberglass hollow pipe (3) and increase the surface spraying RTV that climbs joint (4), to prevent the epoxy tube moisture absorption and to improve its electric property, inwall creeping discharge when preventing condensation.
