Description
Technical field
The present invention relates to a kind of tension resistant four-serial string whole composite insulator replacing device, belong to power circuit maintenance tool technical field.
Background technology
Along with the development of electric power network technique, the heavy in section application of big capacity lead on supertension line is universal day by day, the use of large-section lead, the generation of having bred tension resistant four insulator serial type.Because synthetic insulator has very high anti-pollution flashover ability, use to the strain insulator-string application popularization from the straight line string gradually, but because the tension resistant four-serial synthetic insulator has very big Horizontal Tension, it is very big to cause whole string to change the insulator difficulty.Normally adopt heavy chain block, tight by steel wire rope and the whole closed string of fixing-line device, and the whole string in the lax back of insulator is changed.Adopt the whole string of such instrument to change, not only need to employ a large amount of personnel, material resources and aid, and work efficiency is low, potential safety hazard is big, and the interruption maintenance time is long.
Summary of the invention
Technical problem to be solved by this invention is: be intended to overcome existing tension resistant four-serial string whole composite insulator Work tool heaviness, work efficiency difference and the uneasy congruent problem changed, provide a kind of simple in structure, light, easy to operate, quick, safe in utilization tension resistant four-serial string whole composite insulator replacing device.
Its technical scheme is: a kind of tension resistant four-serial string whole composite insulator replacing device is characterized in that: be made up of front end aerofoil profile card, rear end aerofoil profile card, screw mandrel, arm-tie and forked type joint; Described front end aerofoil profile card middle lower portion is provided with horizontal clip slot, and the both sides of clip slot bottom are provided with vertical screw, and two wing tips of front end aerofoil profile card are respectively equipped with screw; Rear end aerofoil profile card is connected and composed by bolt by the assembly of two symmetries, and the groove that symmetry is offered in two symmetric component joint portions forms a through hole, and two wing tips of rear end aerofoil profile card are respectively equipped with screw; Be connected with forked type joint, screw mandrel, forked type joint, arm-tie and forked type joint between two wing tips of front end aerofoil profile card and rear end aerofoil profile card respectively in turn.
Tension resistant four-serial string whole composite insulator replacing device of the present invention, utilized the gold utensil towing plate at the strain insulator string whole composite insulator two ends on the power circuit and gold utensil extension plate stress point cleverly as this device, be fixed in rocking arm on the leading screw by rotation, screw mandrel is tightened up or loosen, realized string whole composite insulator light, quick and easy maintenance and replacing.Compared with prior art, that this device has is in light weight, work efficiency is high, simple to operate, easy, practical, long service life, safety, characteristics such as reliable are installed, be adapted at using on superhigh pressure and the ultra high voltage tension resistant four-serial string whole composite insulator.
