Fig. 2 is the left view of Fig. 1.
Fig. 3 is the instance graph (the first station) that the present invention applies in a kind of pair of voltage transformer.
Fig. 4 is the instance graph (the second station) that the present invention applies in a kind of pair of voltage transformer.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1 and Figure 2, the present invention includes a case lid 1, case lid 1 below is provided with the first switchboard 2 and second switch plate 3; The first switchboard 2 is upper, second switch plate under.On the first switchboard 2, be provided with three groups of splicing ear A1～A4, B1～B4, C1～C4,4 terminals of every group of splicing ear are on same straight line and apart from equating.The first switchboard 2 is provided with can be along the first switchboard 2 mobile a plurality of conducting strips 8 in surface.Similar with the first switchboard 2, this second switch plate 3 is provided with three groups of splicing ears 2～7,2～7,2～7, and 6 terminals of every group of terminal are on same straight line and apart from equating.On second switch plate 3, being also provided with can be along the second switch plate 3 mobile a plurality of conducting strip 9 in surface.First connecting rod 4 is connected with each conducting strip 8 on the first switchboard 2 through case lid 1, and second connecting rod 5 is connected with each conducting strip 9 on second switch plate 2 through case lid 1.The length of conducting strip 8 is at least linked up two terminals adjacent in first kind terminal, and the length of conducting strip 9 is at least linked up two terminals adjacent in Second Type terminal.The top that first connecting rod 4 and second connecting rod 5 stretch out case lid 1 is separately installed with 6, two knob 6 outsides of knob and is separately installed with cover cap 7.
Below in conjunction with Fig. 3, Fig. 4, working method of the present invention is described.Fig. 3, Fig. 4 are the connection principles of a kind of 20kV and the two voltage transformers of 35kV, and this pair of voltage transformer becomes three part w1, w2, w3 by high voltage winding component, and number of turn ratio is w1:w2:w3=15:15:5.One end of winding w1 connects A1 end, and the other end connects A3 end; One end of winding w2 connects A2 end, and the other end connects A4 end; One end of winding w3 connects X end, and the other end connects A4 end.K1, K2 are of the present invention pair of voltage transformer switch, corresponding the first switchboard of the present invention of K1 wherein, the corresponding second switch plate of the present invention of K2.
As shown in Figure 3, when this transformer need to be operated in 20kV, K1 is switched to the first station, connection A1 end and A2 end and A3 end and A4 end, then winding w1 and winding w2 parallel connection connect with winding w3, have been both 15(15)+5=20kV.As shown in Figure 4, when this transformer need to be operated in 35kV, K1 is switched to the second station, connects A2 end and A3 end, and winding w1, winding w2, winding w3 series connection, be both 15+15+5=35kV.
Accordingly in Fig. 1, Fig. 2, when this transformer need to be operated in 20kV, take off cover cap 7 of the present invention, rotate the knob 6 of first connecting rod 4 tops, drive first connecting rod 4 rotations, and rotatablely moving of first connecting rod 4 is converted to the horizontal movement of conducting strip 8, make conducting strip 8 connect A1 terminal and A2 terminal and A3 terminal and A4 terminals; The motion that conducting strip 8 at B1～B4, C1～C4 is is consistent with on A1～A4.Take off cover cap 7 of the present invention simultaneously, rotate the knob 6 of second connecting rod 5 tops, drive second connecting rod 5 rotations, and rotatablely moving of second connecting rod 5 is converted to the horizontal movement of conducting strip 9, make conducting strip 9 connect 2 terminals and 3 terminals, winding is made as to the number of turn needing., by above action, the present invention makes transformer be operated in 20kV.When this transformer need to be operated in 35kV, by operation similar to the above, conducting strip 8, conducting strip 9 are connected to corresponding terminal and realize.
Same, when the present invention is applied in two voltage transformers of other electric pressures, similar to the above, repeat no more.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
