Description
Technical field
The utility model is related to extra-high voltage, high-voltage transmission line towers cross-arm technical field, and more particularly to a kind of three manage
Formula flexible compound insulator crossarm.
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 being waved in strong wind weather lower wire can cause windage yaw discharge, disliked in thunder and lightning, misty rain etc.
Also often occur the accidents such as lightning flash over, icing flashover, pollution flashover, mist dew flashover under bad weather, threaten the safety of power network
Operation.To eliminate the potential safety hazard that high voltage power transmission is present, from the design requirement of overhead transmission line, it is necessary 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, the increase of this height that will cause steel tower and steel consumption.Thus a series of problems for causing, will greatly improve defeated
The operating cost of electric line.
With the development of science and technology, external insulator and supporting construction unite two into one have developed rigid insulation cross-arm,
But with the rising of voltage class, 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.
Utility model content
The utility model can cancel original mainly solving the technical problems that provide a kind of three-tube type flexible compound insulator crossarm
There is an insulator on line steel tower, reduce steel tower highly, reduce line corridor width, while having enough mechanical strength and good
Good ageing-resistant, decay resistance, can meet high pressure, extra high voltage line steel tower and use.
In order to solve the above technical problems, the technical scheme that the utility model is used is：There is provided a kind of three-tube type flexible
Composite insulation cross arm, is hingedly connected to one another by three tubular type insulator crossarm parts and formed, the tubular type insulator crossarm part
Including：The full skirt of compound material insulation inner core tube and pressure gel in the compound material insulation inner core tube outer surface.
In one preferred embodiment of the utility model, the compound material insulation inner core tube is using FRP composites
It is made through pultrusion plus winding process.
In one preferred embodiment of the utility model, the full skirt is solidifying through automatic pressure using cycloaliphatic epoxy resin
What adhesive process was made.
In one preferred embodiment of the utility model, the tubular type insulator crossarm member outer surface is coated with the painting of fluorine carbon
Material.
In one preferred embodiment of the utility model, the tubular type insulator crossarm part is with tower body also by the company of being hinged
Connect.
The beneficial effects of the utility model are：The utility model has abandoned the design concept of conventional rigid insulation cross-arm, adopts
The flexible structure constituted with being hinged by three tubular type insulator crossarm parts, makes cross-arm be subjected only to axial tension, and in circuit
Direction can freely rotate, and to mitigate and be applied to load on steel tower under broken string state, while having enough mechanical strength and good
Good ageing-resistant, decay resistance, can meet high pressure, extra high voltage line steel tower and use.Specifically, it has the following advantages that：
（1）Three-tube type flexible compound insulator crossarm can cancel the insulator on original line steel tower, reduce steel tower highly；
The length of cross-arm can also be shortened simultaneously, 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 highly；
（3）The full skirt being made of cycloaliphatic epoxy resin has enough mechanical strengths, when three of the parallel connection before and after
During tubular type insulator crossarm, wire hanging position can be easily crawled into along insulator crossarm using with operations staff, carried out often
The observation and maintenance of rule.
