The utility model adopts three post core type cores, three low pressure windings of suit and three high pressure windings on each core limb.Parallel high voltage winding leads on three core limbs connects the three-phase power line respectively, and three low pressure windings on each core limb can use separately, also can in parallelly use.When the low pressure winding used separately, rectifier transformer can connect 3 rectifiers.The utility model can substitute the logical double winding drive rectifier transformer of three Daeporis, and floor space can reduce 50%, and energy-saving effect is remarkable, and than using the logical transformer of three Daeporis, its loss reduces by 15～20%.In addition, the present invention also has higher overload capacity, and operation generally can reach 115% of rated capacity continuously.In addition, it also has characteristics easy to maintenance.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model outline drawing;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is winding suit position view on the core limb (the low pressure winding is in the inboard, and the high pressure winding is in the outside).
Each label is among the figure: 1, iron core; 2, winding; A1～A3, high pressure winding; A1～a3 low pressure winding.
Among Fig. 1, the three-phase three-column heart type structure that adopts unshakable in one's determination, high-low pressure winding concentric arrangement is enclosed within on three core limbs.
Embodiment
Among the figure, three low pressure windings are arranged vertically; Three high pressure windings also arrange vertically and height on corresponding one by one with the low pressure winding.Low pressure winding a1～a3 among the figure on the core limb is loaded on the inboard of high pressure winding A1～A3, certainly, also low pressure winding a1～a3 can be loaded on the outside of high pressure winding A1～A3.
What Fig. 3 drew is the sleeve structure of winding on the core limb, winding sleeve structure on two other core limb is just the same therewith, only low pressure winding a1～a3 is replaced by b1～b3 and c1～c3 respectively, and high pressure winding A1～A3 is replaced by B1～B3 and C1～C3 respectively.
The utility model in the specific implementation, require the high pressure winding will be consistent or deviation very little (promptly will match each other) to the short-circuit impedance of each low pressure winding, if the short-circuit impedance value has big difference, to cause during operation between inner three the high pressure winding parallel branches of transformer and have big circulation, cause the transformer part overheated, short circuit current distributes inequality to cause the transformer anti-short circuit capability to descend during short circuit.Three high pressure windings of suit on 1 each core limb unshakable in one's determination, the reactance calculated value of the winding in the middle of being arranged in is lower 3～8% o'clock than the winding that is arranged in two ends, can eliminate the leakage reactance influence, and the high pressure winding is consistent to the short-circuit impedance of each low pressure winding.Can reach this purpose by the axial and radial physical dimension of adjusting low pressure winding X2, Y2, Z2.
Structurally, adopt the support of strengthening between inboard winding and the core limb, interior winding inner diameter side increases cardboard tube, and interior winding inner diameter side increases technical measures such as stay quantity, improves the mechanical stability of inboard winding.
During the utility model work, parallel high voltage winding leads on three core limbs connects the three-phase power line respectively, three low pressure windings on each core limb can use separately, at this moment the exportable three groups of three-phase electricity of the utility model (a1, b1, c1, are one group, a2, b2, c2 are one group, a3, b3, c3 are one group), thereby can connect 3 rectifiers.Each differs from three groups of output voltage phase places 120 ° single-phase ac-ac frequency changer circuit and forms the three-phase AC-AC frequency changer circuit, realizes the frequency control of the high-power three-phase alternating-current motor of centering.
