Abstract
The utility model discloses a 6kV and 10kV high-voltage double-voltage transformer, which is characterized in that a high voltage winding comprises a first winding, a second winding, a third winding and a double-voltage switch with two workstations; the turn ratio of the first winding to the second winding to the third winding is 4:4:2; two ends of the first winding are respectively connected with an end A1 and an end A3; two ends of the second winding are respectively connected with an end A2 and an end A4; two ends of the third winding are respectively connected with an end X and an end A4; the double-voltage switch is connected with the end A1, the end A2, the end A3 and the end A4 at the first workstation; the double-voltage switch is connected with the end A2 and the end A3 at the second workstation. According to the 6kV and 10kV high-voltage double-voltage transformer, the support on a power grid with two power distribution voltages, i.e. 6kV and 10kV by one piece of equipment can be realized, so that the power grid can work before and after transformation without being replaced; therefore the fund saving is realized.
Description
Technical field
The utility model relates to field transformer, particularly a kind of transformer of supporting 6kV and two kinds of distribution voltages of 10kV.
Background technology
China's utility distribution system all adopts 10kV distribution as main distribution voltage substantially at present.And one of 6kV electric pressure that to be China early stage.Some unit and regional former 6kV electric power system forward 10kV transition, because transition is still needed a period of time, be badly in need of again transformer, can only first use 6kV transformer in the transitional period, after transition completes, be replaced by 10kV transformer, this has just caused the significant wastage of fund again.
Utility model content
The purpose of this utility model is to provide a kind of 6kV and the two voltage transformers of 10kV high pressure, can between 6kV and two kinds of distribution voltages of 10kV, switch, thus saving fund.
The technical solution of the utility model is as follows:
The two voltage transformers of a kind of 6kV and 10kV high pressure, its high pressure winding comprises the first winding, the second winding, the tertiary winding; The number of turn ratio of described the first winding, the second winding, the tertiary winding is 4:4:2; The two ends of described the first winding connect respectively A1 end and A3 end, and the two ends of described the second winding connect respectively A2 end and A4 end, and the two ends of the described tertiary winding connect respectively X end and A4 end; Also comprise a dual voltage switch with two stations, described dual voltage switch connects A1 end and A2 end, A3 end and A4 end at the first station, and described dual voltage switch connects A2 end and A3 end at the second station.
Useful technique effect of the present utility model is:
The utility model can be realized an equipment and support the electrical network of 6kV and two kinds of distribution voltages of 10kV, thereby can work and needn't change in electric network reconstruction front and back, has realized the saving of fund.
Advantage of the present utility model will provide in the description of embodiment part below, and part will become obviously from the following description, or recognize by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is the winding diagram that the utility model is operated in 6kV.
Fig. 2 is the winding diagram that the utility model is operated in 10kV.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1 and Figure 2, high voltage winding component is become three part w1, w2, w3 by the utility model.The number of turn ratio of this three parts winding is w1:w2:w3=4:4:2.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.Also comprise a dual voltage switch K with two stations, dual voltage switch K connects A1 end and A2 end at the first station, and A3 end and A4 end; Connect A2 end and A3 end at the second station.
Design basic ideas of the present utility model are that high pressure winding adopts two kinds of structures of series, parallel simultaneously, and can between cascaded structure and parallel-connection structure, switch.As shown in Figure 1, in the time that transformer need to be operated in 6kV, dual voltage switch K is switched to the first station, adopts winding w1 and winding w2 parallel connection then to connect with winding w3, has been both 4(4)+2=6kV.As shown in Figure 2, in the time that transformer need to be operated in 10kV, dual voltage switch K is switched to the second station, adopts winding w1, winding w2, winding w3 series connection, has been both 4+4+2=10kV.The low-pressure section that can guarantee like this transformer is constant.
Insulation system of the present utility model is dressed to high voltage, to meet whole design of transformer instructions for use.Parameter, the voltage withstand class of switch need meet all service requirements.High-voltage connection Cross section Design is pressed low-voltage and high-current and is selected.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite that does not depart from basic conception of the present utility model, within all should thinking and being included in protection range of the present utility model.
