Bushing shell for transformer threading specific purpose tool
Technical field
When the present invention relates to a kind of power transformer and install, at threading bite in the sleeve pipe, the problem that difficulty is big and the bushing shell for transformer threading specific purpose tool developed.
Background technology
At present, known bushing shell for transformer threading is to put in the sleeve pipe with rope, hitches lead plate, and this method threading then pulls outward, because rope is thin, lead plate is wide, and when wearing, lead plate can snap in the sleeve pipe along last, form bite, need just can finish many times, special trouble, waste of manpower.
Summary of the invention
In order to overcome the deficiency of existing bushing shell for transformer threading method, the invention provides a kind of bushing shell for transformer threading specific purpose tool, this specific purpose tool is simple in structure, convenient and practical, long service life, disposable finishing the work at an easy rate is suitable for using when transformer station or power plant transformer coil lead-in wire are connected operation with sleeve pipe.
The technical solution adopted for the present invention to solve the technical problems is:
Bushing shell for transformer threading specific purpose tool, have conductor barrel and silicon rubber horn mouth, the length of described conductor barrel is greater than the length of sleeve pipe, described silicon rubber horn mouth is made up of the truncated cone-shaped horn mouth of the cylindrical thin footpath mouth of up/down perforation and up/down perforation, cylindrical thin footpath mouth is inserted in the conductor barrel, and the bell-mouthed bottom surface radius of truncated cone-shaped is at least the twice of upper bottom surface radius.
Be fitted with lining in the mouth of described cylindrical thin footpath.
The top of described conductor barrel is by being bolted on the sleeve pipe.
Advantage and effect that the present invention has are:
Bushing shell for transformer threading specific purpose tool of the present invention is owing to have conductor barrel and silicon rubber horn mouth, the length of conductor barrel is greater than the length of sleeve pipe, the silicon rubber horn mouth is up/down perforation, it is made up of cylindrical thin footpath mouth and truncated cone-shaped horn mouth, cylindrical thin footpath mouth is inserted in the conductor barrel, truncated cone-shaped horn mouth bottom surface radius is at least the twice of upper bottom surface radius, this specific purpose tool can wear out the transformer coil lead-in wire smoothly by strop, solve the problem of the easy bite of bushing shell for transformer threading method in the past, improved the operating efficiency of operation field.Simple in structure, convenient and practical, safe and reliable.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is use view of the present invention.
Among the figure: conductor barrel 1, silicon rubber horn mouth 2, pipe 4 in cylindrical thin footpath mouth 21, truncated cone-shaped horn mouth 22, the lining 3, sleeve pipe, sleeve pipe 5.
Embodiment
As shown in Figure 1, bushing shell for transformer threading specific purpose tool of the present invention, cylinder-shaped thin wall conductor barrel 1 and silicon rubber horn mouth 2 with up/down perforation, the length of described conductor barrel 1 is greater than the length of sleeve pipe, described silicon rubber horn mouth 2 is made up of the truncated cone-shaped horn mouth 22 of the cylindrical thin footpath mouth 21 of up/down perforation and up/down perforation, cylindrical thin footpath mouth 21 is inserted in the conductor barrel 1, and the bottom surface radius of truncated cone-shaped horn mouth 22 is at least the twice of upper bottom surface radius.
Be fitted with lining 3 in the described cylindrical thin footpath mouth 21, lining 3 is fixed on conductor barrel 1 the inside with silicon rubber horn mouth 2.When being connected operation with sleeve pipe, uses by transformer station (or power plant) transformer coil lead-in wire.
The top of described conductor barrel 1 is by being bolted on the sleeve pipe 5.
As shown in Figure 2, using method of the present invention is as follows:
The present invention's pipe 4 in the sleeve pipe of sleeve pipe 5 lower ends is penetrated, and truncated cone-shaped horn mouth 22 is stayed the lower end of pipe 4 in the sleeve pipe, is connected with sleeve pipe in order to conductor barrel 1 is fixed with the top of bolt with conductor barrel 1.Strop is suitable behind truncated cone-shaped horn mouth 22 from the top of conductor barrel 1, strop is connected with the transformer coil lead-in wire, thereby successfully transformer lead is worn out.Solve the problem of the easy bite of known bushing shell for transformer threading method, improved the operating efficiency of operation field.
