Background technique
With the continuous social and economic development with the increasingly raising of living standards of the people, the demand to electric power also constantly increases
It is long, in order to meet the needs of long distance powedr transmission, it is badly in need of developing super, extra-high voltage grid.
To 500kV route, single loop width of corridor is 55~60m, and the sum of two single loops can reach 110~120m, on
The size and arrangement of conductor of numerical value are stated, the design conditions such as tower-shaped and span are related.So if being replaced using common-tower double-return
Two single time, width of corridor can reduce half, and if come setting up ultra-high-voltage route in the form of compact multiple-loop line, will
The cost of investment for more reducing line corridor, for soil valuableness, corridor area in short supply undoubtedly has apparent economical
Benefit and social benefit, this sets up the trend of development by China 500kV backbone network is become.
Three-phase conducting wire is placed in corresponding tower window by 500kV compact-type transmission line technology, and is taken between three-phase conducting wire equilateral
The arrangement mode of inverted triangle more efficiently increases the phase conductor division radical of transmission line of electricity, and can be with exquisiter
Mode the phase conductor of transmission line of electricity is arranged and is arranged.
Compact line three-phase symmetrical in theory, parameter be it is full decoupled, without replacing.This is also saved
It saves the expense of construction, reduce the difficulty of construction.Three-phase conducting wire, which all passes through six line yoke plates, to be fixed, and the suspension of V-arrangement insulator chain makes
Position of the conducting wire in tower window is fixed, and is not swung because of wind-force or electric power.
Due to the above-mentioned arrangement of 500 kilovolts of compact line three-phase conducting wires and insulator chain, so that being replaced on the route exhausted
The tool of edge substring cannot occupy biggish space, so the tool of replacement common line insulator chain is not suitable for 500 kilovolts
Compact line.

Plate and otic placode are arranged in a vertical direction.
The interlude to clamping plate is rectangular section, which is yoke plate gripping section, and referred to as yoke plate is lifted at the both ends of this section
Section.
The saddle holds a half thickness of six line yoke plate both ends lower edges respectively, and the upper edge of saddle is and six line yoke plate heads
Along the matched curved surface of shape under both ends.
It is described that clamping plate is fastened six line yoke plates to after folder by clamping screw and nut, the rectangular section of clamping plate is provided with
There are bolt mounting holes in bolt mounting holes, the lower part of the saddle, are fastened between the saddle of respective end by clamping screw and nut.
The adjusting screw rod link block between two otic placodes, adjusts the centre bit of screw rod link block by oblique pull bolted splice
The place of setting offers internal thread hole.
The upper outside of the otic placode has downward opening U-type groove, and the oblique pull, which will be bolted in the U-type groove, to be adjusted
Screw rod link block passes through nut check after adjusting the angle.
Two groups of connection components that this fixture is arranged symmetrically connect with adjusting screw rod carry out mentioning line by six line yoke plates respectively
When operation, a pair of of snap-gauge clamps the head of six line yoke plates, while adjusting the adjusting screw rod of two inclination arrangements, can make two adjustings
Six line yoke plates are vertically up proposed common load transfer simultaneously by screw rod, then can replace two insulator chains, province easy to operate simultaneously
Power.The use of this fixture can be such that two adjusting screw rods arrange respectively along the direction of two insulator chains, can make entirely to mention the Line tool and account for
It is small with space, it is used so being suitable for 500 kilovolts of compact line replacement insulator chains.
