Abstract
The invention discloses a three-pipe type flexible composite insulated cross arm. The three-pipe type flexible composite insulated cross arm is formed in the mode that three pipe-type insulated cross arm parts are connected with one another in a hinged mode, and each pipe-type insulated cross arm part comprises a composite material insulated inner core pipe and an umbrella skirt on the side surface of the composite material insulated inner core pipe of pressure gel. In this way, according to the three-pipe type flexible composite insulated cross arm, a design concept of a former rigid insulated cross arm is abandoned, a flexible structure which is formed in the way that the three pipe-type insulated cross arm parts are connected with one another in a hinged mode is adopted, the cross arm only bears axial tension and can freely rotate in the line direction, and load working on an iron tower under a disconnection condition is reduced; and meanwhile, the three-pipe type flexible composite insulated cross arm has enough mechanical strength and good ageing resistance and corrosion resistance performance, and using by high-voltage and ultra high voltage lines is met.
Description
Technical field
The present invention relates to extra-high voltage, high-voltage transmission line towers cross-arm technical field, more particularly to a kind of three-tube type is soft
Property composite insulation cross arm.
Background technology
Cross-arm as iron tower of power transmission line main support component, for a long time, China or even countries in the world extreme high voltage
The cross-arm of transmission line of electricity is run in the form of steel design suspension insulator string.But, this operation form is severe
There is larger potential safety hazard under weather, such as waving in strong wind weather lower wire can cause windage yaw discharge, dislike in thunder and lightning, misty rain etc.
Also often there are the accidents such as lightning flash over, icing flashover, pollution flashover, mist dew flashover in Jing under bad weather, threatens the safety of electrical network
Operation.To eliminate the potential safety hazard that high voltage power transmission is present, from the design requirement of overhead transmission line, need to increase wire spacing,
This certainly will increased the floor space in transmission of electricity corridor.In the today's society that land resource is increasingly poor, soil money is not only wasted
Source, and drastically increase occupation of land removal expense.And in order to meet the insulation distance of overhead transmission line, it is necessary to increase insulator
The length of string, this will cause the increase of the height of steel tower and steel consumption.Thus the series of problems for causing, will greatly improve defeated
The operating cost of electric line.
With the development of science and technology, insulator and supporting construction are united two into one and have developed rigid insulation cross-arm by foreign countries,
But with the rising of electric pressure, the size and specification of insulator crossarm significantly increase, and considerably increase the difficulty of the manufacturing,
And existing rigid insulation cross-arm can only also meet the use of low-voltage electricity transmission line steel tower, and high pressure, extra-high line ball are not suitable for it
Road steel tower.
The content of the invention
The invention mainly solves the technical problem of providing a kind of three-tube type flexible compound insulator crossarm, original circuit ferrum can be cancelled
Insulator on tower, reduces steel tower height, reduces line corridor width, while with enough mechanical strength and good resistance to old
Change, decay resistance, can meet high pressure, extra high voltage line steel tower and use.
To solve above-mentioned technical problem, one aspect of the present invention is：A kind of three-tube type flexible compound is provided
Insulator crossarm, is hingedly connected to one another by three tubular type insulator crossarm parts and is formed, and the tubular type insulator crossarm part includes：
The full skirt of compound material insulation inner core tube and pressure gel in the compound material insulation inner core tube outer surface.
In a preferred embodiment of the present invention, the compound material insulation inner core tube is drawn using FRP composites Jing
Squeeze and add made by winding process.
In a preferred embodiment of the present invention, the full skirt is using cycloaliphatic epoxy resin Jing automatic pressure gel works
Made by skill.
In a preferred embodiment of the present invention, the tubular type insulator crossarm member outer surface is coated with fluorocarbon coating.
In a preferred embodiment of the present invention, the tubular type insulator crossarm part and tower body are also by being articulated and connected.
The invention has the beneficial effects as follows：The present invention has abandoned the design concept of conventional rigid insulation cross-arm, using by three
Tubular type insulator crossarm part is hinged the flexible structure of composition, makes cross-arm be subjected only to axial tension, and can be with line direction
Freely rotate, mitigate and load on steel tower is applied under broken string state, while with enough mechanical strength and good resistance to old
Change, decay resistance, can meet high pressure, extra high voltage line steel tower and use.Specifically, it has the advantage that：
（1）Three-tube type flexible compound insulator crossarm can cancel the insulator on original line steel tower, reduce steel tower height；Simultaneously
The length of cross-arm can also be shortened, reduce the width of line corridor, reduce engineering removal expense；
（2）Compared with rigid insulation cross-arm, overhanging golden tool string is reduced, therefore can further reduce steel tower height；
（3）There is enough mechanical strengths using full skirt made by cycloaliphatic epoxy resin, when three-tube type in parallel using before and after
During insulator crossarm, wire hanging position can be easily crawled into along insulator crossarm using with operations staff, be carried out conventional
Observation and maintenance.
