In the accompanying drawings: 1, pull rope, 2, upper tube connector, 3, T-shaped rotating shaft, 4, Guan Gai, 5, lower connector, 6, connector, 7 attached covers, 8, conversion connector.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, transformer high-voltage bushing lead-in wire draw-gear, comprise the upper connector be connected with pull rope 1 above and the lower connector 5 be connected with transformer lead below, the pipe lid 4 of band centre bore that upper connector comprises tube connector 2 and is connected with upper tube connector 2, the lower end of lower connector 5 is provided with the connector 6 of transformer lead, the upper end of lower connector 5 is fixed with T-shaped rotating shaft 3, and this T-shaped rotating shaft 3 is rotatably assorted with pipe lid 4 centre bore.Described upper tube connector 2 is threaded with pipe lid 4, and lower connector 5 and T-shaped rotating shaft 3 are threaded fixing.Described connector 6 lower end is provided with attached cover 7, and attached cover 7 upper end is threaded with connector 6, and attached cover 7 lower end is provided with conversion connector 8.According to the difference of conducting rod connecting hole specification, the attached cover 7 of different size can be selected.Described upper tube connector 2 is blind pipe, and the top of blind pipe is provided with cord hole, this cord hole and pull rope 1 compression fit.
Installation method of the present invention is: first, the upper end of upper tube connector 2 is connected with pull rope 1, then the body of rod end of T-shaped rotating shaft 3 is passed from the upper end of pipe lid 4, subsequently go up tube connector 2 to be connected with pipe lid 4, finally the connecting hole of lower connector 5 is connected with the body of rod head of T-shaped rotating shaft 3.
Using method of the present invention is: when carrying out lead-in wire traction to more than 500 kilovolts transformer high-voltage bushings, from sleeve upper end, whole device is put into bushing, device is under gravity through the cavity of bushing, and then the connecting hole of connector 6 with lead-in wire one end conducting rod is threaded, finally use the present invention to carry out lead-in wire traction.When carrying out lead-in wire traction to 110 ~ 500 kv transformer bushings, the conversion connector 8 of the attached cover 7 of corresponding specification is connected on lower connector 5.Use aforesaid operations method to carry out lead-in wire to draw.
Operation principle of the present invention is: T-shaped rotating shaft 3 has the effect of release wire stress and connecting lead wire and conducting rod concurrently.The head of T-shaped rotating shaft 3 is arranged in the internal cavity of tube connector 2 and pipe lid 4, and its effect is indirectly connected with pull rope 1 with pipe lid 4 by upper tube connector 2, simultaneously also guaranteed its can along vertical axes 360 ° rotation, to discharge the stress of lead-in wire; The lower end of T-shaped rotating shaft 3 is connected with lower connector 5, so just indirectly can be connected with conducting rod by the connector 6 on lower connector 5.Such T-shaped rotating shaft 3 is just indirectly all connected to lead-in wire and conducting rod, and T-shaped rotating shaft 3 simultaneously can also rotate to discharge the stress that lead-in wire produces in distraction procedure, so avoid twisting together, dog leg.
