Abstract
The utility model discloses a special tool for disassembling and assembling a current transformer of a 10kV switch cabinet. The special tool comprises a top plate and a bottom plate, wherein the middle of the lower surface of the top plate is hinged and fixed with the inner ends of two lifting arms; the middle of the upper surface of the bottom plate is hinged and fixed with the inner ends of another two lifting arms; the outer ends of the two lifting arms which are hinged on the top plate are respectively hinged and fixed with the outer ends of the two lifting arms which are hinged on the bottom plate, through two hinging shafts; the two hinging shafts are respectively and radially provided with screw holes which are opposite in screwing direction; a double-screwing-direction screw rod is screwed in the two screw holes; and ribs are arranged on the double-screwing-direction screw rod and provides convenience for clamping of a spanner. The special tool disclosed by the utility model effectively solves the problems that the current transformer of the traditional 10kV switch cabinet is time-consuming and labor-consuming in disassembly and assembly and inconvenient to install because of overweight of the current transformer, greatly improves the working efficiency and shortens the power cut time.
Description
One. technical field: the utility model relates to a kind of electrical equipment dismantling devices, particularly relates to a kind of 10kV switch cubicle current transformer tool specially for attaching and detaching.
Two. background technology: flourish along with electric utility, power load also constantly increases, and thing followed electrical equipment is changed, renovation project is also more and more.Wherein 10kV switch cubicle current transformer disassemble and assemble work task is heavy, influenced by the installation site, and nearly all 10kV switch cubicle current transformer disassemble and assemble work is very inconvenience all, thus the manpower and materials of labor.According to statistics, the dismounting of a 10kV switch cubicle current transformer needs 6 people, not only uses great amount of manpower, and has expended a large amount of work-hourses, has influenced economic benefit.
Three. the utility model content:
The utility model technical matters to be solved is: overcome the deficiency of prior art, a kind of reasonable in design, easy to use, high efficiency and the good 10kV switch cubicle current transformer tool specially for attaching and detaching of safety are provided.
The technical scheme of the utility model is: a kind of 10kV switch cubicle current transformer tool specially for attaching and detaching; Contain top board and base plate; In the middle of the said top board lower surface with the inner hinged securement of two lifting arms, in the middle of the said plate upper surface with the inner hinged securement of two other lifting arm, the outer end that is hinged on two said lifting arms on the said top board through two jointed shafts respectively with the outer end hinged securement that is hinged on two said lifting arms on the said base plate; Radially be respectively arranged with the opposite screw of rotation direction on two said jointed shafts; Be combined with the double rotational directions screw rod in two said screws, said double rotational directions screw rod is provided with rib side, is convenient to spanner and fixes.
Said rib side is arranged on an end, two ends or the centre of said double rotational directions screw rod.Said rib side is positive six rib sides, and said spanner is a socket wrench.
The beneficial effect of the utility model is:
1, the utility model solved effectively that traditional 10kV switch cubicle current transformer dismounting mode space is narrow and small, consuming time, consumption power and excessive because of the current transformer quality, problems such as inconvenience are installed, greatly improved work efficiency, shortened power off time.
2, the utility model has reduced the consumption of manpower, and only 2 people of need just can easily accomplish the dismounting of 10kV switch cubicle current transformer, and are time saving and energy saving.
3, reasonable in design, easy to use, high efficiency of the utility model and safety are good, and it is applied widely, is easy to promotion and implementation, has good economic benefit.
Four. description of drawings:
Fig. 1 is the structural representation of 10kV switch cubicle current transformer tool specially for attaching and detaching.
Five. the specific embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-socket wrench, 2-double rotational directions screw rod, 3-lifting arm, 4-top board, 5-base plate.
10kV switch cubicle current transformer tool specially for attaching and detaching contains top board 4 and base plate 5; The inner hinged securement of top board 4 lower surfaces centre and two lifting arms 3; The inner hinged securement of base plate 5 upper surfaces centre and two other lifting arm 3; The outer end that is hinged on two lifting arms 3 on the top board 4 through two jointed shafts respectively with the outer end hinged securement that is hinged on two lifting arms 3 on the base plate 5, radially be respectively arranged with the opposite screw of rotation direction on two jointed shafts, be combined with double rotational directions screw rod 2 in two screws; Double rotational directions screw rod 2 is provided with rib side, is convenient to spanner and fixes.
Rib side is arranged on an end, two ends or the centre of double rotational directions screw rod 2, selects as required, and in the present embodiment, rib side is positive six rib sides, and spanner is a socket wrench 1.
During use, this instrument is placed in the slideway of the switch cubicle outside, inwardly be pushed into below, current transformer position again, rotating spanner; Double rotational directions screw rod 2 makes lifting arm 3 change the folding angle, thereby realizes that top board 4 rises, and being increased to is enough to support till whole the current transformer, dismantles the current transformer check screw then fully; The backward rotation spanner descends top board 4, takes out current transformer, accomplishes a working cycle; Adopt double rotational directions screw rod 2, rising or falling speed is fast, high efficiency.
