Abstract
The utility model discloses a tool special for lead threading of a transformer bushing. The tool achieves the aim of smooth threading of high-voltage leads in the installation process of the transformer high-voltage bushing. The tool is characterized in that three L-shaped supports (5) are respectively arranged on the outer edge of a C-shaped plate (6) at equal interval with the radian, cylindrical landing legs (3) are connected to the bottom ends of the L-shaped supports (5) through hinges (4), the bottom end faces of the cylindrical landing legs (3) are fixedly connected to the top faces of arc plates (1), a circular ring is composed of the three arc plates (1), a fixed pulley (8) is arranged in a C-shaped notch of the C-shaped plate (6), one end of a nylon pulling lead bypasses the fixed pulley (8) to firstly penetrate a center hole of the circular ring composed of the three arc plates (1) to be connected with the transformer high-voltage leads (10), and a fixed bolt penetrates through bolt fixing slotted holes (2) in the arc plates (1) to enable the arc plates (1) to be fixed on the top end face of the transformer bushing. The tool is particularly suitable for installation of the transformer high-voltage bushing.
Description
Technical field
The present invention relates to a kind of instrument that high-voltage lead of transformer is drawn from bushing used in the transformer high-voltage bushing installation process.
Background technology
In the installation and maintenance of carrying electric equipment, what transformer high-voltage bushing was arranged on to transformer will have certain difficulty on army cap.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 mount pad by bushing shell for transformer, the high-voltage connection of transformer to be drawn and passes from sleeve pipe, 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 to 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 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 remove to correct to stepping on double ladder on main transformer the leading-out end that the leading-out end position could be extracted high-voltage connection smoothly; this operational danger is very large; at high-voltage connection, pass in the process of sleeve pipe simultaneously; the phenomenon of lead terminal and the collision of sleeve pipe porcelain vase, easily occur in inconsistent due to lead-in wire with casing axis, causes 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 passed in bushing shell for transformer and C shape plate, uniformly-spaced be respectively arranged with three L brackets on the outward flange of C shape plate 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 on arc, three arcs form an annulus, be provided with the fixed pulley back shaft in the C v notch v of C shape plate, be provided with fixed pulley on the fixed pulley back shaft, one end of imperial draught line is after fixed pulley is walked around, first after the centre bore through three arcs composition annulus, with high-voltage lead of transformer, be connected, set bolt through the bolt on arc 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, make the central axes of central axis and the bushing shell for transformer of this instrument, the pipe-in-pipe angle of inclination is not how many, the high-voltage lead of transformer that imperial draught line draws all can pass sleeve pipe along the central axis of sleeve pipe, thoroughly solve high-voltage lead of transformer incidental clip collision phenomenon when the sleeve pipe, eliminated the installation hidden danger of bushing shell for transformer.
The accompanying drawing explanation
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 passed in bushing shell for transformer and C shape plate 6, uniformly-spaced be respectively arranged with three L brackets 5 on the outward flange of C shape plate 6 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 on arc 1, three arcs 1 form an annulus, be provided with fixed pulley back shaft 7 in the C v notch v of C shape plate 6, be provided with fixed pulley 8 on fixed pulley back shaft 7, one end of imperial draught line 9 is after fixed pulley 8 is walked around, first after the centre bore through three arcs, 1 composition annulus, with high-voltage lead of transformer 10, be connected, set bolt through the bolt on arc 1 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.
After assembling, arc 1 of the present invention, cylindrical supporting leg 3, fixed pulley 8 and C shape plate 6 need not dismantle again as the split part.While being connected with bushing shell for transformer, one end of the imperial draught line 9 that first will be connected with main transformer coil leading-out end is drawn by fixed pulley 8, adjust by hinge 4 size that three arcs 1 form annulus again, the central shaft of this annulus is overlapped with the central shaft of sleeve pipe, simultaneously by rotate whole support make bolt on arc 1 fixedly slotted eye 2 with the screw eye by army cap on the main transformer sleeve pipe, aim at, with set bolt, whole support and sleeve pipe are fixed, drawing imperial draught line 9 just can be smoothly by the coil leading-out end extraction tube of main transformer.
