Description
Technical field
The utility model belongs to a kind of horizontally changing strain insulator string instrument.
Background technology
Change the two points of horizontal strain insulator string of the column wire activity durations of 220kV transmission line for having a power failure long, side of wire was jig is not general, and operating personnel passes in and out wire repeatedly, causes physical demands large.The 15 years above 220kV transmission lines that put into operation mostly adopt ceramic insulator, regularly ceramic insulator is carried out to zero value detection at circuit need in service, zero resistance insulator detection difficulty is large, require high to operating personnel's operative skill, the accuracy of measuring is difficult to ensure, leaves hidden danger to the safe operation of circuit.
According to the connected mode of the side of wire was of the horizontal strain insulator string of 220kV wire, because gold utensil scale error is large, cause the jig of current use to use, side of wire was can only use wire grip to be stuck on wire, easily causes disconnected strand of wire in Renewal process.
Summary of the invention
The purpose of this utility model is just to provide a kind of horizontally changing strain insulator string instrument, the difficulty existing to solve two points of horizontal strain insulator strings of column wire of above-mentioned replacing 220kV transmission line.
Technical scheme:
Horizontally changing strain insulator string instrument, comprises main body, link and set bolt, and main body is made up of two block-shaped consistent clamps, and keyhole is opened at the both ends of every clamp, affixed as a whole with bolt; Link be fixed by bolts to two clamps flat segments one side end keyhole place and be clipped between two clamps.Every clamp is made one by flat segments and oblique section, and the angle of two sections of junctions is 145 ° ± 3 °; Wherein oblique segment length is the 55-60% of flat segments length; Be fixed on link between two clamps vertical with the flat segments of clamp, and the annular distance of link axially and the vertical consistency of clamp.
Can be made in the manner described above a horizontal changing strain insulator string instrument, when use, by its clamping and be fixed on the L shaped yoke plate of side of wire was of horizontal strain insulator string to be replaced, recycling lever hoist and climb the related tool of power circuit tower, the horizontal strain insulator string that can change needs easily be changed.
Whole operating process side of wire was operating personnel do not go out wire, not damage wires.Utilized the related device of strain insulator string side of wire was, clamp is directly stuck on three eye plates, coordinates the instruments such as Lever Blocks, bottle supporting bar to change, and has reduced labour intensity, has improved operating efficiency; Two points of horizontal strain insulator strings of column wire of 220kV circuit are changed, there is good applicability.
Brief description of the drawings
Fig. 1 is horizontal changing strain insulator string tool construction schematic diagram.
Fig. 2 is the left view of horizontal changing strain insulator string instrument.
Embodiment
Below in conjunction with accompanying drawing, as embodiment, scheme is illustrated.
Open keyhole screw 7 with reference to the left end of Fig. 1,2, two clamps 6 and be connected and fixed, right-hand member is opened keyhole, and link 5 is arranged between two clamps, is fixedly connected with bolt 4, and makes link 5 vertical with the flat segments 3 of clamp 6.Clamp 6 use sheet metals cut into flat segments 3 and oblique section 1, and the angle 2 of two sections is controlled between 145 ° ± 2 °, so that while using, coordinate with the L shaped yoke plate of the side of wire was of horizontal strain insulator string.Link 5 is fixed on after 6 of two clamps, the annular distance 8 of link 6 axially and clamp 6 vertical consistencies.After being fixed as one by bolt 4 and screw 7 by two clamps 6, top-down orthographic projection length is 44cm, oblique section of width 4.1cm, the thin 2.5cm of portion of flat segments.Taking edge on clamp as standard meter, straight segment length 30cm, oblique segment length 18 cm; Two sections of angles are chosen to be 146 °.
In addition, in order to make the position that link 5 is installed have enough width, the upper edge of flat segments by middle part to right-hand member bevel(l)ing, keyhole is opened near clamp right-hand member middle part, makes clamp maintain good intensity.And there is 2.5cm dimension width in flat segments thin portion in middle part, when handled easily, take with holding.
With reference to Fig. 2, link 5 is except installing rear annular distance direction and clamp 6 longitudinally in opposite directions, and the shape of link is done the shape of rectangularity and the smooth connection of two terminal circle arc, coordinates to connect to hang time easy to use with Lever Blocks.
Concrete occupation mode:
1, enter working site, ground electrician puts out rope and Work tool classification successively, and has assembled.
2, on tower, No. 1 electrician carries electroscope, earth connection is stepped on tower to correct position, hangs up properly earth connection after identifying the true no-voltage of circuit three-phase with electroscope.
3, on tower, No. 1 electrician carries pin pulling clamp, kit, restricts to operation cross-arm without string for binding a plait, coaster, transmission, fastens seat belts, and hangs up properly and transmits rope at operation cross-arm correct position.
4, on tower, No. 2 electricians carry pin pulling clamp, kit tower to operation cross-arm.
5, lever hoist, jig and bottle supporting bar are passed to operation cross-arm by ground electrician, and on tower, No. 1 electrician assembles card, cucurbit before jig.
6, after on tower, No. 2 electricians carry jig, card, along insulator string to conductor wire end, is stuck in rear card on yoke plate and fixes, and on tower, 1, No. 2 electrician's cooperation hangs over lever hoist on the right-angle hanging ring 5 of rear card.
7, on tower No. 1 electrician by firm the tying up on the sub-steel pin of cross-arm-end suitable insulation of transmission rope, tighten up cucurbit stressed to cucurbit after, on tower, 1, No. 2 electrician coordinates bottle supporting bar is bundled in position.Continue to tighten up cucurbit by insulator string load transfer to cucurbit, check impact bearing tool stressed normal after, on tower, No. 2 electricians free conductor wire end insulator.
8, ground electrician controls and transmits rope firm tying up on new assembling insulator, ground electrician tightens up and transmits rope, on tower, No. 1 electrician frees cross-arm-end insulator, on tower, 1, No. 2 electrician coordinates and will be replaced insulator string and haul out bottle supporting bar, and ground electrician controls and transmits rope and put down old insulator string and lift by crane new insulator string simultaneously.
9, on tower, 1, No. 2 electrician coordinates and puts into bottle supporting bar by newly assembling insulator string, install cross-arm and conductor wire end insulator, after checking that W pin or R pin, insulator and gold utensil connect well, on tower, No. 1 electrician loosens screw mandrel to insulator and is stress, after on tower, No. 2 electricians impact and check that new replacing insulator string is qualified, on tower, No. 1 electrician loosens cucurbit completely, completes more and changes jobs.
