Description

Phase-splitting pressure-adjusting type three cracking rectifier transformers
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of phase-splitting pressure-adjusting type three cracking rectifier transformers.
Background technology
Rectifier transformer is the power transformer of rectifying installation.The characteristics of rectifying installation are former side's input ACs, and export direct current behind the secondary square tube over commutation original paper.Unsteady flow is the general name of rectification, adverse current and three kinds of working methods of frequency conversion, and rectification is wherein most widely used a kind of.The transformer of using as the rectifying device power supply is called rectifier transformer.Industrial rectification DC power supply major part is all obtained by rectifier transformer and rectifying installation by AC network.
Use in the maximum chemical industry of rectifier transformer, high-power rectifying device also is that secondary voltage is low, and electric current is very big, and is therefore very big, thus they to become with electric furnace aspect a lot of be similarly, promptly before described architectural feature point, rectifier transformer possesses too.The characteristics of rectifier transformer maximum are that secondary current has been not simple alternating current, because the unidirectional conducting feature of follow-up rectifier cell, each phase line no longer simultaneously, stream has load current but the plastic flow conduction, unidirectional pulsating current becomes direct current through filter, the secondary voltage of rectifier transformer, electric current is not only relevant with capacity connection group, as three-phase bridge rectification circuit commonly used, the rectifying circuit of two inverse band interphase reactors, for same VD, the secondary voltage of the rectifier transformer that electric current is required and electric current are inequality, therefore the calculation of parameter of rectifier transformer is prerequisite with the rectifying circuit, and general parameters calculates and all begins to calculate to primary side from secondary side.
Because it is a lot of high order harmonic components of containing of non-sine that rectification becomes winding current, in order to reduce harmonic pollution,, must improve the pulse number of rectifying installation in order to improve power factor to electrical network, this can solve by the method for phase shift.The purpose of phase shift is to make between the end line voltage of the same name of rectifier transformer secondary winding a phase shift is arranged.
And along with applying of ac variable speed technology, supporting with it drive rectifier transformer demand is also increasing, and general drive rectifier transformer and common electric power transformer device structure are similar, adopts the common double winding type.Along with disconnected the going deep into that the user uses ac variable speed technology, also more and more higher to the requirement of rectifier transformer.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of phase-splitting pressure-adjusting type three cracking rectifier transformers are provided.
For realizing the purpose of this utility model phase-splitting pressure-adjusting type three cracking rectifier transformers, include net side winding, the corresponding working end of described net side winding is provided with valve side winding, wherein: described net side winding is cracked into three independent winding in the axial direction, and each independent winding is provided with independent shunting switch; Described valve side winding also is cracked into three individual branches.
Further, above-mentioned phase-splitting pressure-adjusting type three cracking rectifier transformers wherein, are provided with at least three independently frequency conversion units on the valve side winding of described individual branches.
Further, above-mentioned phase-splitting pressure-adjusting type three cracking rectifier transformers, wherein, described independent winding is equipped with two coils.
Adopt technical solutions of the utility model, reduced loss and floor space, for the user creates sub-considerable economic and social benefit.What is more important is provided with at least three independently frequency conversion units on the valve side winding by individual branches, can be effectively and the various frequency convertor assembly of being sold on the existing market close, realize applying.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the organigram of phase-splitting pressure-adjusting type three cracking rectifier transformers.
The implication of each Reference numeral is as follows among the figure:
1 net side winding, 2 valve side windings
3 shunting switchs, 4 coils
5 frequency conversion units
Embodiment
Phase-splitting pressure-adjusting type three cracking rectifier transformers as shown in Figure 1, include net side winding 1, be provided with valve side winding 2 in the corresponding working end of net side winding 1, its special feature is: the net side winding 1 of employing is cracked into three independent winding in the axial direction, independent winding is equipped with two coils 4, and each independent winding is provided with independent shunting switch 3.Corresponding with it is that the valve side winding 2 that the utility model adopts also is cracked into three individual branches.Like this, each tapping voltage carries out the middle part pressure regulation by an independent shunting switch 3, carries out pressure regulation mutually respectively by 3 pairs of three independent shunting switchs are every.
In conjunction with the utility model one preferred implementation,, be provided with at least three independently frequency conversion units 5 on the valve side winding 2 of individual branches for the ease of being connected with the effective of follow-up motor.Like this in actual application, the utility model can cooperate with the frequency conversion unit 5 of Siemens in three individual branches that the cracking of valve side goes out, make corresponding three the frequency conversion units 5 of three branches, form three-phase 5Hz~40Hz AC power by frequency conversion unit 5, the driving steel mill electric machine moves, and reaches the effect of " one-machine-multi-function ".
Be used for seeing, independent shunting switch 3 is arranged again on each independent winding owing to also be cracked into three parts in the axial direction at three net side windings 1 in conjunction with actual making of the present utility model.Like this, can carry out pressure regulation mutually respectively, reduce between each winding of every phase with this and cause circulation because of being in the different stray fields by 3 pairs of three independent shunting switchs are every.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, after adopting the utility model, compare with three traditional transformer rectification forms, tripartition formula rectifier transformer has reduced loss and floor space, for the user has created considerable economic and social benefit.What is more important is provided with at least three independently frequency conversion units on the valve side winding by individual branches, can be effectively and the various frequency convertor assembly of being sold on the existing market close, realize applying.
Certainly, more than only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
