Abstract
The utility model relates to a single-phase regulating transformer, which is suitable for a single-phase load or no excitation voltage regulating transformer, in particular to a rectifier transformer and an electric furnace transformer. The central column of the iron cores with three stems is provided with an input regulating winding and a low voltage winding, a side column is provided with a high voltage winding which is connected in parallel with a part of number of windings of the input regulating winding, the low voltage winding is connected in series with an output winding, and the single-phase regulating transformer is formed. The utility model has the advantages of small number of windings, small number of iron cores, material saving, working hours saving, low electricity consumption, etc.
Description
The utility model belongs to a kind of structure of transformer, is a kind of single-phase adjustable transformer that tap is arranged on winding, be applicable to single-phase have carry or off circuit tap changing transfor mer, especially rectifier transformer and furnace transformer.
At present, single-phase two-core voltage regulating transformer as rectifier transformer and furnace transformer, for realizing adjusting the big purpose of voltage range, adopts the structure of tertiary winding pressure regulation as shown in Figure 1.Its formation is: at first T unshakable in one's determination
1On the input winding 1S that joins with power supply is housed and for the low pressure winding 2 of output and have the pressure regulation winding 3 of tap, at second T unshakable in one's determination
2On high pressure winding 4 that is in parallel with pressure regulation winding 3 a part of numbers of turn and the output winding 5 that is in series with low pressure winding 2 are housed, by changing the different tap of 4 pairs of pressure regulation windings of high pressure winding 3, make the total output voltage U of low pressure winding 2 and output winding 5 series connection backs
2Value changes, and satisfies the requirement of adjusting voltage.The weak point of this structure is: the winding sum has 5 more than, and material usage is big, electrical loss is high.
The purpose of this utility model is to overcome the weak point in the above-mentioned prior art, and the number of windings is provided and number unshakable in one's determination is few, when saving material and worker, a kind of single-phase adjustable transformer that electrical loss is low.
The purpose of this utility model can reach by following measure: it comprises low pressure winding 2, output winding 5, high pressure winding 4 etc., its special character is: input pressure regulation winding 1 and the low pressure winding 2 that has tap is housed on the stem stem B of the T unshakable in one's determination with A, B, three stem stems of C, high pressure winding 4 and output winding 5 are housed on the stem stem C of T unshakable in one's determination, output winding 5 is in series with low pressure winding 2, one end of high pressure winding 4 is connected with an end or the other end break-in of input pressure regulation winding 1, and the other end of high pressure winding 4 is connected with the tap conversion of input pressure regulation winding 1.Like this, just can change output voltage U
2
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is existing a kind of single-phase two-core voltage regulating transformer structure principle chart;
Fig. 2 is an example structure schematic diagram of the present utility model.
With reference to Fig. 2.The utility model is to be equipped with when using on the stem stem B of the T unshakable in one's determination with A, B, three stem stems of C and electrical network joins and has tap (f
1, f
2F
m) input pressure regulation winding 1 and low pressure winding 2, high pressure winding 4 and output winding 5 are housed on stem stem C, do not adorn winding on the stem stem A and only play the magnetic shunt effect of stem stem B.One end of high pressure winding 4 and the tap (f that imports pressure regulation winding 1
1, f
2F
m) the conversion connection, the other end is connected with the head end or the terminal break-in of input pressure regulation winding 1.Provide output voltage U after exporting winding 5 and low pressure winding 2 being contacted mutually
2
The two ends and the line voltage U that remains unchanged of input pressure regulation winding 1
1Be connected, cause the input pressure regulation winding 1 on the stem stem B and the terminal voltage of low pressure winding 2 to remain unchanged.One end of high pressure winding 4 and the tap (f that imports pressure regulation winding 1
1, f
2F
m) conversion connects, the terminal voltage that can cause exporting winding 5 changes and makes low pressure winding 2 and the output voltage U of exporting after winding 5 is connected
2Value changes.When the head end of the other end of high pressure winding 4 and input pressure regulation winding 1 or terminal break-in are connected, the induced potential direction of output winding 5 is changed, its stack of induced potential positive direction or opposite direction with low pressure winding 2 be superposeed, thereby enlarged output voltage U
2The excursion of value.
The utility model has replaced the T unshakable in one's determination of two hollows in the prior art with three stem stems T unshakable in one's determination
1And T
2, replaced input winding 1S and the pressure regulation winding 3 in the prior art with input pressure regulation winding 1.Therefore, the utility model compared with the prior art have the number of windings and quantity unshakable in one's determination is few, when saving material and worker, advantage such as electrical loss is low.
