Description
Technical field
This is suitable for the replacing instrument that invention relates to transmission line insulator string, especially a kind of compact line six-multiple conductor link plate clamping tool and application thereof.
Background technology
In compact line, division number and the conventional line division number of wire are different, arrangement is divided in usual employing six, and namely every six roots of sensation sub-conductor is separately fixed in six through holes of six yoke plates by cylindrical arrangement, then the insulator string through being connected with six yoke plates is fixed on shaft tower.Because the safety operation of compact line is apart from smaller, particularly in high altitude localities 500kV compact line, be only 3.2m at the following earth potential of height above sea level 1000m and equal potential working minimum safe distance relatively, during equal potential working, alternate minimum safe distance is only 4.6m; Be only 3.4m at the above earth potential of height above sea level 1000m and equal potential working minimum safe distance relatively, during equal potential working, alternate minimum safe distance is only 5.0m.And when insulator string is damaged need to change time, is at present usually all take power failure operation mode to change, although fail safe is high, makes troubles to the life of people and the production of enterprise.
Prior art, the Work tool of compact line straight line bunch of insulator is Six-divided conductor hook (patent No.: ZL 200720085185.6), a little method is changed compact linear string and is used two Six-divided conductor hooks, total weight just reaches 40 kilograms, volume is large and heavy, effort is compared during transmission, and combinational gap is likely inadequate when the transmission of instrument, jeopardize the safety of staff, during conducting wire hook, operating personnel just needs to walk around insulator string, a thread hook is respectively installed in insulator string both sides, moving range is large, be unfavorable for the safe distance controlling live line working, and waste time and energy.
Said method and device thereof exist following four and implement a difficult problem:
1, operating personnel needs to pay larger labour intensity.Six-divided conductor hook volume is large, weight large, when instrument transport, carrying, needs many people to carry out the vehicle with larger space; In operation process, no matter be ground staff thread hook being passed to setting, or equal potential working personnel when mounted, all will pay the labour of high strength;
2, require high when instrument transmits to combinational gap.The general tower height of compact line is 30 meters to 50 meters, and Six-divided conductor hook is because volume is large, weight is large.When instrument transmits near tower window, need tail rope outside tower body, pull out the enough safe distances of certain distance guarantee.Therefore in transmittance process, operation is implemented to need landform residing for shaft tower to have 30 meters to 50 meters smooth landform commodiously and along on line direction, and most shaft tower cannot ensure this condition in mountain areas large residing for South-West Yunnan, the southeast of Guizhou Province, many south electric network compact line corridors such as Gui Xi, Gui Bei.
3, power tool, device, operation procedure are numerous and diverse.Said method is implemented to be formed by multi-mode operation instrument, device, Automatic manual transmission, and operation layout is multi-point and wide-ranging, and program is numerous and diverse, and operation process is careless slightly, likely causes the generation of personal injury or equipment breakdown.
4, during conducting wire hook, operating personnel just needs to walk around insulator string, respectively installs a thread hook in insulator string both sides, and moving range is large, is unfavorable for the safe distance controlling live line working, and wastes time and energy.
Summary of the invention
In compact line, division number and the conventional line division number of wire are different, arrangement is divided in usual employing six, and namely every six roots of sensation sub-conductor is separately fixed in six through holes of six yoke plates by cylindrical arrangement, then the insulator string through being connected with six yoke plates is fixed on shaft tower.And six yoke plate position of centre of gravitys are positioned on the big hole at middle part.Utilize the feature of above-mentioned line design, the problem of this secondary solution is: provide one can with wire lifting device with the use of, and the six-multiple conductor link plate clamping tool that reliably can be connected with six yoke plates, be applicable to the live line working of compact line, solve equipotential personnel in equipotential end shift position too much and can not ensure safe distance a difficult problem, ensure the needs of circuit hot-line repair.
The present invention solves the problems of the technologies described above taked technical scheme solution: provide a kind of compact line six-multiple conductor link plate clamping tool, comprise two piece insulated hanging poles being connected supporting with wire lifting device respectively, one end of every root insulated hanging pole is connected with a wire lifting device, the insulated hanging pole other end is connected with the connection end of yoke plate clamp, the centering ring of the draw-in groove and six yoke plates that mate six yoke plates in the middle part of link plate clamping tool is nested, and forms the instrument that whole group is changed compact line insulator string.
By link plate clamping tool serve as conductor wire end promote stressed instrument realize lifting lead wire change insulator string.Link plate clamping tool and six-multiple conductor yoke plate annulus broad in the middle be nested card jail, yoke plate clamp two ends are connected with one end of two groups of insulated hanging poles respectively, and the other end of insulated hanging pole is connected with wire lifting device, three with the use of, yoke plate and wire can be promoted.
Use compact line six-multiple conductor link plate clamping tool to change the operational method of compact line insulator string, comprise the steps:
1, earth potential working personnel carry insulation transmission rope arrival main material position above six yoke plates of 500 kilovolts of compact line insulator strings and install transmission coaster, Ground Operation personnel are passed to two groups of wire lifting devices on tower on ground respectively, and on tower, earth potential operating personnel is installed to line lifting device on the main material directly over wire.
2, Ground Operation personnel are delivered to two insulated hanging poles on tower more respectively, and on tower, earth potential operating personnel is connected one end of insulator suspension rod respectively with wire lifting device, and adjust mounted instrument and make it vertical with wire.
3, Ground Operation personnel transmit rope by insulation again and described yoke plate clamp are reached conductor wire end equal potential working personnel, equal potential working personnel are connected one end of yoke plate clamp with one end of insulated hanging pole, again the draw-in groove in the middle part of yoke plate clamp is placed on the centering ring of six yoke plates, adjustment yoke plate clamp makes it to contact closely with six yoke plates, and the yoke plate clamp other end is connected with another root insulator suspension rod.
4, after installing kit, on tower, earth potential operating personnel and equal potential working personnel conscientiously check that each tie point is connected firmly, and adjustment wire lifting device makes yoke plate clamp both sides stress balance.On tower, earth potential operating personnel stringing lead lifting device, stressed by insulated hanging pole, and simultaneously yoke plate clamp mentions six yoke plates, reaches the effect mentioning wire, when insulator string does not stress and replaceable insulator string.
Beneficial effect of the present invention is:
1, the assembling solving former replacing instrument is numerous and diverse, heavy, personnel's transposition is many, coefficient of safety this key issue low, instrument is lightweight, reasonable in design, and fitting operation is simple and convenient, alleviate the labour intensity of personnel and ground staff on tower, improve operating efficiency;
2, on yoke plate clamp, be provided with two connection ends, be applicable to dissimilar insulated hanging pole, have larger versatility.
