Abstract
The utility model relates to a flange fixing tool of a hollow composite insulator for a 2250kV outdoor industrial-frequency test. The flange comprises a connection part and a through hole. The flange fixing tool comprises a fixing part which is connected with the flange and a support part which is fixedly connected with the fixing part and extends into the through hole of the flange. The support part is in a close fit with the through hole. Because of the support effect of the support part of the flange fixing tool, the situation that the flange can not be mounted or used as a result of diametrical deformation caused by gravity in the mounting, hoisting and transportation processes can be avoided.
Description
Technical field
The utility model relates to a kind of tooling device of UHV transmission equipment, particularly relates to the flange fixing tool that a kind of 2250kV outdoor industrial frequency experiment is used hollow combined insulator.
Background technology
Along with the needs of the development of power industry, particularly extra-high voltage electric transmission and transformation, also more and more for the demand of hollow combined insulator.The common outdoor hollow insulator that uses is porcelain insulator, and since porcelain insulator resistant sudden strain of a muscle ability, difficult quality control, easily broken in the transportation installation process, and in use, need periodic cleaning, this has brought a lot of inconvenience all for installation and use.For addressing these problems, the electrical circuitry equipment industry has been developed traditional composite hollow insulator.
The 2250kV outdoor industrial frequency experiment has 3.5 meters with the internal diameter of the flange of hollow combined insulator, 3.75 meters of external diameters, because its diameter is large, volume is large, and important heavy, also has problem in its carrying, lifting and finished product transportation and produces.For example, because diameter is too large, the relative wall thickness is thinner, and is easy to so that the distortion on the diameter appears in this flange, and the material of general flange is aluminium, and therefore, its distortion can't be replied.Thereby the flange after this distortion is difficult to be installed on the insulating cylinder of hollow combined insulator.Even install, this Big Diameter Flange be in lifting, also can cause flange to lose circle because of same cause in the transportation, and cause on the flange installing hole can't with corresponding auxiliary equipment, install such as instrument transformer.
The utility model content
In view of this, be necessary to provide the flange fixing tool of a kind of fixedly 2250kV outdoor industrial frequency experiment with hollow combined insulator.
A kind of 2250kV outdoor industrial frequency experiment flange fixing tool of hollow combined insulator.Described flange comprises a connecting portion and a through hole.Described flange fixing tool comprises a fixed part that is connected with flange, a support portion that is fixedly linked with described fixed part and extend in the flange through hole.This support portion and through hole closely cooperate.
Compared with prior art, because the supporting role of the support portion of this flange fixing tool, can avoid the described flange can be because the reason of gravity cause flange distortion on the diametric(al) to occur in installation, lifting and transportation, and cause and to install or to use.
Description of drawings
The 2250kV outdoor industrial frequency experiment that Fig. 1 provides for the utility model structural representation of the flange fixing tool of hollow combined insulator.
Fig. 2 is 2250kV outdoor industrial frequency experiment the flange fixing tool of hollow combined insulator and the assembling schematic diagram of flange of Fig. 1.
Embodiment
For the utility model is further described, lifts a preferred embodiment and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, it is the structural representation that 2250kV outdoor industrial frequency experiment provided by the utility model is used the flange fixing tool 100 of hollow combined insulator.Described flange fixing tool 100 comprises a fixed part 11 and a support portion 12 that is fixedly linked with this fixed part 11.
Described flange fixing tool 100 is used for guaranteeing that described 2250kV outdoor industrial frequency experiment can not be out of shape in transportation or hoisting process with the flange 200 of hollow combined insulator.Described flange 200 comprises a connecting portion 21, with a through hole 22 that is arranged on described flange 200 middle parts.Be provided with a plurality of installing holes 23 on the described connecting portion 21.These a plurality of installing holes 23 are used for the accessory that this flange 200 is corresponding with other, such as installations such as instrument transformers.Described through hole 22 is used for other accessories are set, such as wire, and perhaps insulating material etc.
Described flange fixing tool 100 is a tabular frock of annular made from metal material, and described fixed part 11 is positioned at the periphery of described annular frock, and described support portion 12 is positioned at the inside of described annular frock.Described flange fixing tool 100 can be made by materials such as iron, aluminium.Described fixed part 11 is body formed with support portion 12-, thereby is fixedly linked.
Be provided with a plurality of frock bolts hole 13 on the described fixed part 11.These a plurality of frock bolts hole 13 and installing hole 23 corresponding settings are to be fixedly linked this flange fixing tool 100 by bolt (not shown) with flange 200.The maximum gauge of described fixed part 11 can be suitable with the diameter of flange 200.
The through hole 22 of the maximum gauge of described support portion 12 and flange 200 is suitable, to closely cooperate with this through hole 22, arrives the purpose that supports this through hole 22 thereby cross.It is large that the described fixed part 11 of the Thickness Ratio vertically of described support portion 12 thickness is vertically wanted, thereby can be when being fixed on fixed part 11 on the flange 200, described support portion 12 can extend in the through hole 22, and then plays the effect of the through hole 22 that supports described flange 200.The thickness vertically of described support portion 12 can be than large 5 centimetres of described fixed part 11 thickness vertically.Described support portion 12 can be one-body molded with described fixed part, perhaps is fixedly connected with by additive method, such as welding.
Compared with prior art, because the supporting role of the support portion 12 of this flange fixing tool 100, can avoid the described flange 200 can be because the reason of gravity cause flange 200 distortion on the diametric(al) to occur in installation, lifting and transportation, and cause and to install or to use.
In addition, those skilled in the art can also do other variation in the utility model spirit, as long as it does not depart from technique effect of the present utility model, all should be included in the utility model scope required for protection.
