The time and labor are saved, the high altitude operation labor intensity is reduced, and the special tool for exchanging the first insulator of the tension insulator string is safe and reliable.
Description
Technical field:
The present invention relates to a kind of replacing strain insulator string first insulator specific purpose tool, belong to power system transmission of electricity fortune inspection field。
Background technology:
In transmission line of electricity, strain insulator string determine that side of wire first insulator voltage's distribiuting is high because of voltage's distribiuting feature, deterioration rate is high, null value very easily occurs, need to be replaced, as changed not in time, it is easy to causes line insulation intensity to reduce, affect circuit safe operation。At present, the fixture of existing replacing strain insulator double insulator string monolithic insulator, can only start to change from the second of insulator chain, owing to fixture self restriction cannot change first insulator, therefore the method processing this type of defect can only be integral replacing insulator chain, and operation is loaded down with trivial details, longevity of service, not only increase work high above the ground labor intensity, and add potential safety hazard。
Summary of the invention:
It is an object of the invention to overcome the deficiency of above-mentioned prior art to provide a kind of simple in construction, weight is little, simple to operate, be easily installed dismounting, it is easy to operation, it is possible to single carry tower and complete operation, whole insulator chain need not be removed, time saving and energy saving, reduce work high above the ground labor intensity, the safe and reliable specific purpose tool changing strain insulator string first insulator。
The purpose of the present invention can be reached by following measure: a kind of specific purpose tool changing strain insulator string first insulator, it is characterized in that it includes steel cap fixture, the middle part of steel cap fixture is provided with groove, the left end of steel cap fixture connects the left end of rocking handle; the left end of rocking handle connects left leading screw; left leading screw connects the upper end of Zola's plate by left screw; the lower end of Zola's plate connects the left end of L-type fixture by upper left screw; L-type fixture is the fixture of left end opening; L-type fixture left end is provided with built-in L-type yoke plate draw-in groove, and L-type fixture left end is provided with lower-left screw hole；The right-hand member of steel cap fixture connects the right-hand member of rocking handle, and the right-hand member of rocking handle connects right leading screw, and right leading screw connects the upper end of right pulling plate by right screw, and the lower end of right pulling plate connects the right-hand member of fixture by bottom right screw。
The present invention can produce following good effect compared with the prior art: the present invention is a kind of safe and reliable, facilitation, practical replacing insulator instrument, it is provided with fixture, arm-tie, steel cap fixture, rocking handle four part, fixture is left end opening fixture, built-in draw-in groove, it is possible to L-type yoke plate is firmly stuck in draw-in groove；Left and right two panels arm-tie, by leading screw working tension, shortens the distance between fixture and steel cap fixture, allows insulator chain relax；Steel cap fixture is stuck on insulator chain gold utensil by groove；After equipment installs, pull rocking handle。It has:
1. simple in construction, weight is little, simple to operate, it is simple to installing/dismounting, it is easy to operation, it is possible to single carry tower and complete operation；
2. when need not remove whole insulator chain, realize changing yoke plate place first insulator, time saving and energy saving, reduce work high above the ground labor intensity, safe and reliable。
