Description

A kind of line insulation test shaft tower
Technical field
The utility model relates to high-voltage electrical apparatus line insulation test tower structure technical field.
Background technology
Transmission line of electricity adopts insulator or insulator string to guarantee the distance of line-to-ground and other objects usually.Insulator or insulator string electric property quality are the bases that guarantees the good operation of transmission line of electricity.In order to determine the electric property of insulator or insulator string, need carry out the insulation characterisitic test to insulator or insulator string.The insulating properties difference of the insulator of varying environment, different size, different materials or insulator string, in order to obtain the insulating properties of insulator or insulator string, need to carry out electrical performance test to it.Usually the electrical test of insulator or insulator string is carried out on true type tower, but true type tower body is long-pending huge, and occupation of land is many, and changes insulator or insulator string needs work high above the ground, has increased personnel's operating risk.
The utility model content
The problems such as the utility model has solved the line insulation test needs true type tower, and its construction period is long, and cost is high, changes insulator string during test and need to carry out work high above the ground, and efficiency is low, and operating risk is large.
Technical solution of the present utility model is: a kind of line insulation test shaft tower, the utility model tower body adopts door type mount structure, and crossbeam adopts aluminum alloy materials, and column adopts carbon steel material, the tower body basis is fixed by concrete, and pre-embedded anchoring bolts connects column; On crossbeam, jig is hung in installing, fixed block on jig, tower body bottom configuration electric block, the wire rope lifting insulator string that draws by electric block.
The utility model jig is flexible, can require to adjust jig to the distance of test with the shaft tower side column according to test requirements document.
The utility model tower body bottom electric block utilizes wire rope, by the fixed pulley on jig, insulator string is carried out to descending operation.
The utlity model has following advantage:
1, construction cost is low, and the cycle is fast.Ordinary test is with the multiplex true type tower of shaft tower, and along with the rising of electric pressure, the steel that true type tower needs are more, and basis is also larger, and the construction period of basis and tower material is long, and expense is high, and that this test tower has is simple in structure, and required tower material is less meeting under test requirements document, and the construction period is fast simultaneously.
2, use the electric block operation, efficiency is high, and the electric block maintenance of motor is convenient.While needing to change insulator or gold utensil, by the fixed pulley on electric block and jig, insulator string is carried out to descending operation, the more artificial high-altitude of its operating efficiency is changed high, and is because electric block is positioned at top, basis, ground, while breaking down, easy to maintenance simultaneously.
3, avoid work high above the ground, reduced operating risk.Generally on true type tower, do experiment, while changing insulator or gold utensil, need high-altitude operation vehicle and personnel to operate on it, the utility model shaft tower operates at shaft tower bottom configuration electric block, without work high above the ground, and the personnel's operating risk while having avoided high-altitude.
Below in conjunction with the drawings and specific embodiments, the present invention is further explained.
The accompanying drawing explanation
Fig. 1 is test shaft tower schematic diagram;
Fig. 2 is the fixture structure schematic diagram;
Fig. 3 is the left view of Fig. 2.
The specific embodiment
A kind of line insulation test shaft tower, the utility model tower body adopts door type mount structure, and crossbeam 4 adopts aluminum alloy materials, and column 5 adopts carbon steel material, and tower body basis 7 is fixed by concrete, and pre-embedded anchoring bolts connects column 5; On crossbeam, jig 3 is hung in installing, fixed block on jig 3, tower body bottom configuration electric block 6, the wire rope 2 lifting insulator strings 1 that draw by electric block.
The utility model jig is flexible, can require to adjust jig to the distance of test with the shaft tower side column according to test requirements document.
The utility model tower body bottom electric block utilizes wire rope, by the fixed pulley on jig, insulator string is carried out to descending operation.
As shown in Figure 1, the utility model adopts door type tower, and column 5 adopts carbon steel material, adopts the form of sectional, every section 4000mm, and door type tower column determines according to the requirement of test tower height the hop count that adopts.The door type tower column cross-section of segmentation is square, side is rectangle or trapezoidal, for making foundation stressed evenly, guarantee that basis is firm, the test tower column is trapezoidal near the section of foundation lateral layout, as shown in Figure 1, the test tower column is 600mm*600mm near one section cross sectional dimensions on basis 7, and top and other sections cross sectional dimensions are 400mm*400mm.The door type tower column of segmentation adopts the material of angle steel and band steel, and angle steel is used in four vertical edges of column as basic support, and the 80mm*6mm angle steel is adopted in not segmentation; Band steel is used in the intensity that column is strengthened in the column side, and the band steel after the long 6mm of 550mm ~ 650mm is adopted in the column side, and two ends are bolted on angle steel with 2 respectively.Between the segmentation column, reaching 4, column and crossbeam adopts angle steel to be connected with bolt.Jig 3 as shown in Figures 2 and 3, is fixed on crossbeam, and top is steel angle structure, bottom is the band steel with hanging point, and pulley is fixed on hanging point by U-shaped ring, and jig is fixed by 2 screw rods up and down, convenient disassembly, can be by dismounting mobile holder, the distance of adjusting clamp and side column.Jig 3 tops are long 450mm angle steel, utilize 2 screw rods that surpass 400mm length to be connected with the band steel of bottom band hanging point, and band steel is fixed with nut, and the bottom hanging point is the prototype groove, by U-shaped ring, connects movable pulley.Can require distance to adjust the position of jig 3 according to insulator string.Basis is dark 1000mm, and the square hole of each 1200mm of length and width, by concreting, the shaft tower bottom is fixed by stone bolt, the long 700mm of stone bolt, four jiaos of every root posts are fixed by 4 stone bolt, and stone bolt is when carrying out concreting in buried foundation.The electric block motor is fixed on the bottom of shaft tower column, on the shaft tower crossbeam, needs 2 cover jigs to guarantee electric block wire rope energy and a door type tower column parallel vertical, and electric block adopts the line traffic control switch to control, and as required insulator string is carried out to lifting.But the design simulation wire hangs on the insulator string bottom, and test voltage directly adds on analog conducting wire.
