The utility model has the advantages of assembly of the split welded type linkage plate by screw bolts, convenience for installation and aesthetic appearance; meeting the installation requirements of eight multiple conductors; without generating electric corona and radio interference; reducing wind resistance and reducing the vibration of wires in breeze.
Description
Technical field
The utility model is the supporting gold utensil of 1000KV UHV transmission line, particularly a kind of UHV transmission line yi word pattern strain insulator-string.
Background technology
The transmission of electricity of 1000KV and above electric pressure is called UHV transmission.Building the UHV transmission network, is the desirability of China's economic development and power industry.
At present, the principal voltage grade of China is 500KV, can't adapt to 1000KV extra-high voltage grid needs.
1, in configuration aspects, used yoke plate adopts the butt joint welding in the existing 500KV ultra high voltage strain insulator-string, the all very difficult control of perpendicularity between the two boards and not all right degree, existing 500KV ultra high voltage strain insulator-string mainly is applicable to conductors on quad bundled, guarantees that the yoke plate of sub-conductor division radical and spacing is the quadripartion yoke plate.
2, the electric pressure that it was suitable for, existing 500KV ultra high voltage strain insulator-string, its voltage withstand class only is 500KV when the electrical network operate as normal.
3, aspect corona and radio interference, existing 500KV ultra high voltage strain insulator-string is only satisfied under the effect of 500KV voltage not to produce corona, and radio interference when voltage raises, will produce corona and radio interference less than 60 decibels.
4, aspect intensity, existing its total stretching resistance of 500KV ultra high voltage strain insulator-string is 650KN, also can't satisfy the 1000KV ultra high voltage, and total stretching resistance is the specification requirement of 1024.8KN.
Summary of the invention
The purpose of this utility model is, solves above-mentioned existing existing problem, a kind of UHV transmission line yi word pattern strain insulator-string that provides a kind of 1000KV of satisfying ultra high voltage to require.
The utility model is achieved in that and comprises that the hanging point gold utensil is connected with U type ring by screw, U type ring with adjust plate and be connected, insulator passes through right angle link plate, yoke plate, ball-eye and is connected with the adjustment plate; Insulator connects socket-clevis eye, all press shading ring to be connected with socket-clevis eye, socket-clevis eye connects yoke plate, yoke plate connects the right angle link plate, the right angle link plate connects another right angle link plate, the right angle link plate connects yoke plate, yoke plate is by screw and right angle link plate, the right angle link plate connects yoke plate by screw, have A, B, C, D, E, F, G, H connecting hole thereby constitute, and be connected with the prolongation pull bar, prolong pull bar and connect the right angle link plate by U type link, the right angle link plate connects adjusts plate, adjusts plate and connects strain clamp; All press shading ring to be connected on the yoke plate.
Advantage of the present utility model is, 1,1000KV ultra high voltage strain insulator-string adopts bolt combination together with split welded type yoke plate, and is easy for installation, good looking appearance.2, owing to adopt split welded type yoke plate, reach being connected of each parts, thereby satisfied eight bundle conductor installation requirements.3,1000KV ultra high voltage strain insulator-string is suitable for voltage 1000KV; Can not produce corona and radio interference.4, can reduce the resistance of wind, reduce the lead aeolian vibration.
