Abstract
The utility model relates to a 110 line strain-resistant double-string insulator clamping fixture for replacing insulator strings on an electric power line. The double-string insulator clamping fixture is characterized in that a front clamping plate is connected with one end of a strain double-fork rod by a threaded rod and a back clamping plate is connected with the other end by the threaded rod, and an adjustment rod for adjusting tightness is mounted on a middle position of the strain double-fork rod. A determined adjustment scope is 1010-1770 mm. Work difficulty that the 110 kV strain-resistant tower porcelain insulator is replaced to be composite insulators can be effectively reduced, work speed of insulator replacing is raised and work efficiency is raised. Improved tool devices are in an operation state, personnel's safety belts are tied on an iron-tower cross arm and are thoroughly separated from replaced devices, and personnel safety factor is raised. A line secondary protection apparatus can be added, device safety factor is raised and power failure time is effectively shortened. Investment is small and benefits are large. Work efficiency is greatly raised under conditions of an invariable personnel amount and an invariable pole place.
Description
Technical field
A kind of utensil that the utility model uses when relating to a kind of power circuit replacing insulator string relates in particular to the two insulator string jigs of a kind of 110kV line tension.
Background technology
Existing replacing insulator string instrument, mainly by: front card, rear card, arm-tie, bottle-holding rack four parts form, before during operation, card is arranged on side of wire was, rear card is arranged on cross-arm side, connects arm-tie, connects bottle-holding rack, tightens up leading screw and carries out replacing insulator, changes single insulator string complete; Change successively the single insulator string of next group.At present Hainan, Qinghai Province electric company to administer 110kV strain tower of transmission line hanging net operation insulator be 9 insulators of porcelain, porcelain insulator length is 1314mm, and strain insulator mostly is pair insulator strings.Our company is transforming circuit energetically, and porcelain insulator is replaced by composite insulator, and composite insulator length is 1505mm.Original instrument leading screw stroke when replacing insulator is short, operational difficulty, is unfavorable for personal safety and device security.Operating personnel's safety belt ties up to insulator or the wire place of replacing; Original instrument can't install the wire second protection additional; Original engagement tool is rope ladder, is subject to the landform restriction.Can only change an insulator string during original tool operation, changing needs the adjustment instrument after complete, then changes next insulator string, and the activity duration is long, danger is larger.
The utility model content
The utility model is in order to overcome the deficiency of existing replacing insulator string instrument, provide a kind of 110kV line tension two insulator string jigs, for composite insulator structure and length, in conjunction with real work, to original Work tool improve, perfect, make it can satisfy porcelain insulator and change and can adapt to more changing jobs of composite insulator again, improve operating efficiency, reduce labour intensity, shorten interruption duration, stop potential safety hazard.
The technical solution of the utility model is: the two insulator string jigs of 110kV line tension, this jig is comprised of former and later two clamps and stringing double fork lever, adjusting rod, it is characterized in that, clamp after clamp, the other end are connected with by threaded rod too before an end of stringing double fork lever is connected with by threaded rod, and be provided with in the middle part of stringing double fork lever for the adjusting rod of transferring elasticity.
The two insulator string jigs of described 110kV line tension is characterized in that this jig according to the assembled length of line insulator string is: 1314mm, 1505 mm, definite adjustable range is: 1010-1770mm.
The two insulator string jigs of described 110kV line tension is characterized in that described former and later two clamps are isosceles triangle.
The beneficial effects of the utility model
One, can effectively reduce work difficulty, the raising replacing insulator operating rate that 110kV strain tower porcelain insulator is replaced by composite insulator, shorten interruption duration, thereby increase work efficiency.
Two, during the tool operation after improving, the personal security band ties up on the steel tower cross-arm, thoroughly is separated from the equipment that is replaced, and improves the personal security coefficient; Can install the circuit secondary protector additional on the other hand, improve the device security coefficient; Flat ladder is aluminium alloy structure, has eliminated the landform restriction.
Three, the trial-production of this instrument investment is little, benefit is large, in the situation that personnel amount, the shaft tower place is constant greatly increases work efficiency.
Four, this instrument has good practicality, adaptability, for present Qinghai Power Grid 110kV circuit O﹠M operating mode, has promotional value.
Five, can effectively avoid waste of material, reduce the wastage, satisfy the demand of circuit regular maintenance and maintenance.
