Description
Technical field
The present invention relates to power system high voltage substation equipment manufacturing technology field, is that a kind of manufacture is hollow specifically
The alignment pressure-bearing bushing pipe of composite insulator.
Background technology
In hollow combined insulator silicon rubber umbrella manufacturing process, epoxy resin fiberglass pipe (hereinafter referred to as fiberglass tubes)
The silicon rubber of outer wall vulcanizes under 150 DEG C of high temperature and 15MP pressure, and fiberglass tubes can not bear so huge pressure at high temperature,
Therefore a steel liner tube must be lining into fiberglass tubes, otherwise fiberglass tubes are inherently by pressure break.
The bushing pipe used during existing hollow combined insulator sulphurated siliastic umbrella cover in fiberglass tubes is to be more than 10mm with wall thickness
Seamless steel pipe Precision Machining form, its external diameter is identical with glass bore, and carries identical taper, mutually coincide it is closely connected.Cause
This, it is adapted only to the winding fiberglass tubes produced by the use of identical size bushing pipe as winding pipe mold.
The axis shape of the glass fibre and pipe that wind fiberglass tubes forms an angle, and successively cross winding forms certain thickness
Fiberglass tubes, there is preferable anti-atmospheric pressure performance, suitable for there is the sleeve pipe composite insulator of high-voltage isulation gas in making.But
Fiberglass tubes are wound with pipe axial direction identical glass fibre, therefore anti-bending strength is bad, and rigidity is poor, and amount of deflection is big, is less adapted to use
In the post composite insulator that making has higher requirements to bending strength and stiffness.And winding fiberglass tubes low production efficiency, pipe table
The processing capacity of the turning in face and the both ends discarded termination of cutting is big, and turning waste material and two ends waste material all have no value, and one
As processing method be burning or landfill, but burn and produce toxic gas, then centuries are difficult to degrade landfill, destroy air, soil
And descendants is left a legacy of trouble at water source, this is wound around the maximum sequelae that fiberglass tubes production leaves.
In order to solve the above problems, inventor herein had once invented the major diameter pultrusion pipe (patent No.
ZL201320522551.5).Through the winding pipe Experimental Comparison with same diameter, wall thickness and length, pultrusion pipe is bent than winding pipe
Intensity is big 3 times.As one end is fixed, apply same flexure load in the other end, pultrusion pipe bending deformation quantity only has the 1/ of winding pipe
3.If that is, keep post composite insulator bending strength and bending deformation quantity it is constant, the diameter or wall of fiberglass tubes
Thickness can reduce 1/3, greatly reduce production cost.In addition, pultrusion pipe can continuous pultrusion, discard termination, pipe table without both ends
Also without turnery processing, whole production process does not produce the waste material of pollution environment in face.
Compared with winding pipe, pultrusion pipe no doubt has many good qualities, but when pultrusion pipe exceedes certain length, has slight curved
Song, although amount of bow is much smaller than standard GB/T/T25096-2010《Alternating voltage is compound absolutely with pillar higher than 1000V transformer stations
Edge --- definition, test method and acceptance criterion》Setting, but this flexural deformation makes bad insertion in pultrusion fiberglass tubes
The rigid liner being coincide with its inwall.Gases at high pressure and liquid were once filled with fiberglass tubes by we, to offset fiberglass tubes vulcanization
The pressure born during silicon rubber, but find that two hang-ups can not solve：1st, gas or liquid pressing and release time in fiberglass tubes
Be difficult harmonious with speed and silicon rubber expanded by heating pressing time and speed outside fiberglass tubes, otherwise cause pultrusion fiberglass tubes by
External pressure pressure break, otherwise it is pressed within power explosion；2nd, it is used as the filler between the steel liner tube and fiberglass tubes by the use of liquid or gas, it is impossible to
The pultrusion pipe of bending is straightened.Therefore, bushing pipe a kind of while that there is alignment and two big function of pressure-bearing how is found, has become use
Pultrusion pipe manufactures the biggest problem of composite insulator with hollow support.
The content of the invention
The present invention is in view of the above-mentioned problems, aim to provide a kind of school that hollow combined insulator is manufactured with epoxy glass pultrusion pipe
Straight pressure-bearing bushing pipe.
A kind of alignment pressure-bearing bushing pipe for manufacturing hollow combined insulator is by 3 groups of metal liner 1, solid particulate matter 2 and end cap
Into.The rigidity of metal liner 1 is more than smaller (specific small more than by the internal diameter of lining fiberglass tubes by the amount of deflection of lining pultrusion pipe 4, diameter
Few, must be depending on the rigidity of glass length of tube, flexibility and metal liner), reserve the gap of filled solid particulate matter 2.Gold
Belong to the both ends of bushing pipe 1 welding plugging plate 1-3, closure pipe is provided with bolt 1-1, is connected by nut 1-2 and the end cap at both ends 3 solid
It is fixed.Wherein an end cap is provided with filling hole 3-1 and capping 3-2, for pouring into solid particulate matter 2.Solid particulate matter 2 is by fiberglass tubes
The pressure transmission born during 4 outer wall sulphurated siliastic umbrella cover is on metal liner 1, to avoid pressure break fiberglass tubes.
Solid particulate matter 2 is the fine particle with certain fluidity, as button, nonmetallic globule, metal are husky, non-
Metal sand etc..Compare through multiple material, after a diameter of 0.5mm-5mm stainless shot mixes by a certain percentage, there is mobility
It is good, pour into pour out conveniently, filling it is closely knit, without extruding shrinkage, it is non-breakable the features such as, the first choice for fixing particulate matter 2 can be used as
Material.
The rigidity of metal liner 1 and the flowable of solid particulate matter 2 are dexterously combined together by the present invention, are solved
Pultrusion fiberglass tubes are straightened and two big key technical problem of pressure-bearing.Enable pultrusion fiberglass tubes to be widely used in manufacture Hollow Pillar to answer
Close insulator.This composite insulator with hollow support using pultrusion fiberglass tubes as plug, there is high mechanical strength, electric property
It is good, shock resistance is strong, save material, in light weight, easy transportation and installation, energy consumption are low, no waste mine pollution, it is green the advantages that, than
