Description
Technical field
The utility model is the supporting gold utensil of 1000KV UHV transmission line, particularly a kind of UHV transmission line duplex 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 duplex 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, U type ring is connected with the adjustment plate, insulator is connected with the adjustment plate by parallel link plate, towing plate, ball-eye, grading ring is 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 yoke plate, on yoke plate, be provided with A, B, C, D, E, F, G, H connecting hole, be connected with the prolongation pull bar by U type link, prolong pull bar and connect the right angle link plate, 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.
