Background technique
High-voltage frequency conversion and speed-adjusting is a kind of to the matched special transformer of frequency converter with dry type converter transformer, and secondary side has
Multiple windings, winding are had a certain degree by epitaxy delta connection shape, by concatenation technology, can effectively eliminate harmonic wave
Influence to power grid.
Dry-type transformer includes arraying from left to right to epitaxy delta connection mode as shown in Figure 1: in the prior art
U, V, W three-phase coil, every phase coil includes 3 taps of sequence setting, respectively head end tap 1, centre tap 2 and end
Tap 3；The centre tap 2 of dry-type transformer three-phase coil is joined end to end respectively with end tap 3, forms extend-triangle connection
Knot prolongs rim portion between the head end tap 1 and centre tap 2 of every phase coil.
It is as shown in Figure 2: in the prior art, on the every phase coil of dry-type transformer, the phase coil of from left to right successively arranging
Head end tap 1, centre tap 2 and end tap 3.According to shown in Fig. 1, by the centre tap 2 of dry-type transformer three-phase coil with
End tap 3 joins end to end respectively, forms epitaxy delta connection, it can be seen that leading between centre tap 2 and end tap 3
There is the place that interference intersects in line, when multiple windings of dry-type transformer secondary side are connected into epitaxy delta connection mode,
Then the intersection place between conducting wire can be very much, and not only unsightly, there is also very big security risks, if insulation processing is bad, very
To meeting discharge short.
Summary of the invention
The object of the present invention is to provide a kind of dry-type transformer, it is connected into solving existing dry-type transformer three-phase coil and prolongs
Because the chiasma interference between conducting wire has security risk when the triangle junction of side.
To achieve the above object, the present invention provides a kind of dry-type transformers, including U, V, the W to array from left to right
Three-phase coil, every phase coil include 3 taps of sequence setting, respectively head end tap, centre tap and end tap；Every phase
The end tap of coil is arranged on the left of the centre tap of the phase coil.
The beneficial effect of this dry-type transformer is:, can by adjusting the position of each tap of dry-type transformer three-phase coil
Chiasma interference when effectively avoiding dry-type transformer three-phase coil being connected into epitaxy delta connection between conducting wire, so as to avoid
Security risk caused by interfering because of wires cross；It is easy to operate simultaneously, and winding displacement effect is more beautiful, improves production
Efficiency and competitiveness.
