Description
One, technical field
The utility model belongs to electric power accessory is installed, and relates in particular to a kind of high-voltage power line conductive line butt joint and fixture.
Two, background technology
Ultra-high-tension power transmission line is delivered to transformer station and each user from power plant, and closely then hundreds of rice unit is then over thousands of kilometer, and a circuit divides single time and many times.The every lead that single time lead 3 lines, 1 to 2 of ground wire, 2 of many times ground wires, lead 3 * return number, circuit play not-go-end must connect into one whole ability and accomplish electricity, the lightning protection effect sent.At present power department is when setting up and keep in repair ultra-high-tension power transmission line, and the method for lead butt joint adopts pincers to press and two kinds of hydraulic pressure usually.So-called pincers are pressed: line tower foundation and shaft tower just begin to put the stringing engineering after erectting completion, just begin crimping from beginning to end after the complete disc lead is put in exhibition.At first need during crimping two wires head is end to end cut, pricks, washes, wipes, smeared, contain aluminium hydraulic pressed connecting pipe; Liner is coated with vaseline, amount, survey, draw, the crimping marking, again two the end of a thread and liner are inserted aluminium hydraulic pressed connecting pipe; Connecing the marking and use pressing tongs, pressing mold crimping in proper order, need stop behind every pressure one mould to press second mould after half a minute, is example with a LGJ-120 steel reinforced aluminium conductor; Need to press 24 moulds, it is straight with aluminium hydraulic pressed connecting pipe row also to use wooden mallet after pressing, through managing acceptance(check); Stamp crimping people steel seal, carry out crimping relative recording and signature, press a joint need consume more than one hour.So-called hydraulic pressure: working procedure is basic identical with the pincers pressure, and hydraulic pressure is that internal steel core, outer aluminum steel adopt steel pipe and twice crimping of aluminum pipe to form respectively, presses a joint need consume more than half hour.
Simultaneously ultra-high-tension power transmission line send electricity to transformer station and each user from power plant, lead all need all rise, end, fixing on the shaft tower strain insulator cross-arms such as terminal, corner, T connect, segmentation, generally all be that employing hydraulic pressure or strain clamp dual mode are fixed.Hydraulic way and above-mentioned lead hydraulic way are basic identical, and two lines are respectively with after the crimping of strain insulator pipe, and the strain insulator cross-arm both sides that are fixed on shaft tower link to each other with drainage thread; The strain clamp mode generally is used for 240 and reaches following small bore lead, 4 kinds of existing branches.With ND-203 type strain clamp, it has 4 row's U-bolts, 4 pressing plates like the LGJ-120-150 line.Its method is: take the row of 4 on strain clamp U type nut, closed pin and latch apart, on angle tower, the work high above the ground personnel carry out the marking on the line of keeping well by sag for the first time; With line Panasonic, half an hour approximately consuming time, the ground handling personnel stop lead-in wire by the marking; Cut off unnecessary lead, twine the long aluminium armor tape of 1.5M, put into strain clamp in stamp positions; After tightly leading 4 row's U type nuts and pressing plate, the wire clamp of anti-line the and bowl head, porcelain vase etc. are connected, carry out again tightening up the second time and open; Hanging wire consuming timely needs half an hour again on the strain insulator cross-arm.Prior art is seen through construction, operation, maintenance experience and the effect of decades; Really have safe and reliable, power worker's skilled operation, management advantages such as explicit stipulation and standard, rate of failure be less are arranged; The construction battle line is long, scene is big but exist; Human and material resources, tool equipment, machinery, vehicle input amount are big, and labor strength is big, problems such as inefficiency.
Three, summary of the invention
The purpose of the utility model provides a kind of high-voltage power line conductive line simple in structure, high efficiency and docks and fixture.
The technical scheme of the utility model is: it comprises lead docking facilities and wire fixing device two parts, and said lead docking facilities is to be made up of oblate sleeve and semi-round ring shape joint, and the arc surface of semi-round ring shape joint is wedge shape; Said fixture is to be made up of bowl head, wedge sleeve, wedge shape clamping plate, " U " type bolt and pressing plate, is provided with wedge shape annulus through hole in the wedge sleeve, the madial wall ripple circular arc of wedge shape clamping plate.The wedge shape clamping plate lozenges lower end of fixture is provided with the drainage thread Wiring nose, also is provided with two on the Wiring nose and connects circular hole.
The beneficial effect of the utility model is: owing to adopt wedge shape to drawing connected mode the lead docking calculation; Wire fixing method is adopted a bowl wedge shape strain clamp fixing means; Have simple in structure, easy to operate, advantages such as labor strength is little, operating efficiency height, will save a large amount of human and material resources and financial resources for power department.
Below in conjunction with accompanying drawing the utility model is further described.
