Abstract
The invention discloses a special tool for lead threading of a transformer bushing, which solves the problem of smooth threading of a high-voltage lead during an installation process of a high-voltage bushing of an existing transformer. The special tool comprises three L-shaped supports (5) arranged on the outer edge of a C-shaped plate (6) at equal radian intervals respectively, wherein cylindrical support legs (3) are connected to the bottom ends of the L-shaped supports (5) via hinges (4); the bottom end surfaces of the cylindrical support legs (3) are fixedly connected to the top surfaces of arc-shaped plates (1); the three arc-shaped plates (1) form a circular ring; a fixed pulley (8) is arranged in the C-shaped notch of the C-shaped plate (6); one end of a nylon traction wire (9) rounds the fixed pulley (8), penetrates through the central hole of the circular ring formed by the three arc-shaped plates (1), and then is connected with a high-voltage lead (10) of a transformer; fixing bolts penetrate through bolt fixing slots (2) in the arc-shaped plates (1) to fix the arc-shaped plates on the top end surface of the transformer bushing. The special tool is especially applicable to installation of the high-voltage bushing of the transformer.
Description
Technical field
The present invention relates to a kind of instrument that high-voltage lead of transformer is drawn that in the transformer high-voltage bushing installation process, uses from bushing.
Background technology
In the installation and maintenance of carrying electric equipment, will certain difficulty be arranged on the army cap with what transformer high-voltage bushing was installed in transformer.Because, the mount pad of bushing shell for transformer generally is obliquely installed, require the gradient of sleeve hoisting to want consistent with the gradient of the rising mount pad of sleeve pipe, after being lifted on bushing shell for transformer on the mount pad, the high-voltage connection of transformer to be drawn from sleeve pipe and pass, the insulation wimble fraction of transformer is entered in the voltage equalizing ball of sleeve pipe, prevent distortion, this has brought very large difficulty just for lifting and the drawing smoothly of high-voltage connection of sleeve pipe.Prior art is drawn high-voltage connection from sleeve pipe, to adopt soft nylon rope to install a special-purpose fastening means of lead-in wire additional, by the adjustment of stay cord angle, allow all the time high-voltage connection and sleeve pipe keep same gradient, guarantee to go between non-warping in passing the process of sleeve pipe and get stuck.At the scene in the operating process; the phenomenon that the main transformer coil of high-voltage lead of transformer blocks at inside pipe casing often can occur; need the staff to step on double ladder to the main transformer and remove to correct the leading-out end that the leading-out end position could be extracted high-voltage connection smoothly; this operational danger is very large; pass in the process of sleeve pipe at high-voltage connection simultaneously; because lead-in wire is inconsistent with casing axis, the phenomenon of lead terminal and sleeve pipe porcelain vase collision easily occurs, cause the damage of equipment.
Summary of the invention
The invention provides a kind of bushing shell for transformer and connect the line specific purpose tool, solved the technical barrier that existing transformer high-voltage bushing connects smoothly at installation process mesohigh lead-in wire.
The present invention solves above technical problem by the following technical programs:
A kind of bushing shell for transformer connects the line specific purpose tool, comprise bushing shell for transformer, the high-voltage lead of transformer that in bushing shell for transformer, passes and C shape plate, on the outward flange of C shape plate, uniformly-spaced be respectively arranged with three L brackets radian, the bottom of the L bracket cylindrical supporting leg that has been connected through the hinge, the bottom face of cylindrical supporting leg is fixedly connected on the end face of arc, be provided with fixedly slotted eye of bolt at arc, three arcs form an annulus, in the C v notch v of C shape plate, be provided with the fixed pulley back shaft, be provided with fixed pulley at the fixed pulley back shaft, after one end of imperial draught line is walked around from fixed pulley, be connected with high-voltage lead of transformer after passing first the centre bore that three arcs form annulus, set bolt pass on the arc bolt fixedly slotted eye arc is fixed on the bushing shell for transformer top end face.
The central axis of the centre bore of three annulus that arc forms and the central axes of bushing shell for transformer.
Because the present invention is fixed on the end face of the bushing shell for transformer that will install, the central axis of this instrument of making and the central axes of bushing shell for transformer, how many pipe-in-pipe angles of inclination is not, the high-voltage lead of transformer that imperial draught line draws all can pass sleeve pipe along the central axis of sleeve pipe, incidental clip collision phenomenon when thoroughly having solved high-voltage lead of transformer and passing sleeve pipe has been eliminated the installation hidden danger of bushing shell for transformer.

Fig. 1 is structural representation of the present invention.
Embodiment
A kind of bushing shell for transformer connects the line specific purpose tool, comprise bushing shell for transformer, the high-voltage lead of transformer 10 that in bushing shell for transformer, passes and C shape plate 6, on the outward flange of C shape plate 6, uniformly-spaced be respectively arranged with three L brackets 5 radian, the bottom of L bracket 5 is connected with cylindrical supporting leg 3 by hinge 4, the bottom face of cylindrical supporting leg 3 is fixedly connected on the end face of arc 1, be provided with fixedly slotted eye 2 of bolt at arc 1, three arcs 1 form an annulus, in the C v notch v of C shape plate 6, be provided with fixed pulley back shaft 7, be provided with fixed pulley 8 at fixed pulley back shaft 7, after one end of imperial draught line 9 is walked around from fixed pulley 8, be connected with high-voltage lead of transformer 10 after passing first the centre bore that three arcs 1 form annulus, set bolt pass on the arc 1 bolt fixedly slotted eye 2 arc 1 is fixed on the bushing shell for transformer top end face.
The central axis of the centre bore of annulus that three arcs 1 form and the central axes of bushing shell for transformer.
Need not dismantle again after arc 1 of the present invention, cylindrical supporting leg 3, fixed pulley 8 and C shape plate 6 assemble and be the split part.When being connected with bushing shell for transformer, one end of the imperial draught line 9 that will be connected with main transformer coil leading-out end is first drawn by fixed pulley 8, adjust the size that three arcs 1 form annulus by hinge 4 again, the central shaft of this annulus is overlapped with the central shaft of sleeve pipe, simultaneously by rotate whole support make on the arc 1 bolt fixedly slotted eye 2 aim at the screw eye with army cap on the main transformer sleeve pipe, with set bolt whole support and sleeve pipe are fixed, draw imperial draught line 9 just can be smoothly with the coil leading-out end extraction tube of main transformer.
