Abstract
The invention relates to a self-saturating reactor for a rectifier transformer. In a same phase inverse parallel three-phase bridge circuit, currents of same phase inverse parallel two branch copper bars are the same, but with different directions, so that the same phase inverse parallel two branch copper bars (working winding) can penetrate the same group of iron cores, the directions when the working winding penetrates the same iron core are reverse, and current directions of the same phase inverse parallel two branch copper bars in the same group of iron cores can be always the same. The self-saturating reactor for the rectifier transformer has the advantages of low production cost, good performance, low consumption, low noise and the like, and can be widely applicable to large-size metal electrolytic rectifier transformers.
Description
Technical field
The present invention relates to a kind of rectifier transformer autotransducer.
Background technology
In large-scale electrolytic etching of metal rectifier transformer, generally adopt autotransducer that output voltage is carried out the certain limit continuous voltage regulating; Its operation principle: in the electrolytic rectifier transformer, every branch road work winding (copper bar) seals in the iron core group of autotransducer, utilize the variation of the direct current of control winding to change magnetic flux unshakable in one's determination, thereby change the inductance value that magnetic permeability realizes regulating reactor; Realize adjusting transformer valve side output voltage, stablize effects such as direct current, minimizing current fluctuation.
Each rectification brachium pontis of the autotransducer of traditional structure by: one group of group unshakable in one's determination, a work winding (being generally copper bar) that passes group unshakable in one's determination, control winding constitute.Because the large rectifier transformer direct current is very big, valve side work winding (copper bar) adopts the cophase counter parallel connection circuit usually.Its connection principle as shown in Figure 1; Two kinds of laying methods are arranged usually: a kind of is the external attached type autotransducer that is independent of outside the rectifier transformer fuel tank, and another kind is the built-in formula autotransducer that shares same fuel tank with rectifier transformer.Under this purposes, the autotransducer of traditional structure quantity unshakable in one's determination is many, manufacturing is loaded down with trivial details, loss, noise are big.
Summary of the invention
The object of the present invention is to provide a kind of rectifier transformer autotransducer, it has reliable and stable, the advantage of low-loss and low noise.
The present invention is achieved like this, it comprises autotransducer iron core, two branch road copper bars and controls winding, it is characterized in that two branch road copper bars pass the autotransducer iron core, two branch road copper bars of three-phase bridge cophase counter parallel connection share same group of autotransducer iron core.Two branch road copper bars of described cophase counter parallel connection direction when passing same group of autotransducer iron core is opposite.
Rectifier transformer valve side exports autotransducer group unshakable in one's determination, control winding, rectifier cabinet, the confluence copper bar that load end generally comprises valve side work winding (copper bar), is connected on work winding (copper bar) to.The content that the present invention relates to is the autotransducer of new structure, and it comprises the autotransducer iron core group, passes two branch road work windings (copper bar) unshakable in one's determination, controls winding.Feature is that two branch road work of cophase counter parallel connection winding (copper bar) shares same group of autotransducer iron core group.
The present invention realizes principle: the size of current equidirectional on its adjacent two arms of three characteristics of the middle term bridge cophase counter parallel connection is opposite, so we can be through two branch road work windings (copper bar) of cophase counter parallel connection on the same group of iron core group, direction was opposite when the work winding (copper bar) of these two branch roads passed same iron core group, realized that the direction of operating current in same iron core group on the two branch road work windings (copper bar) is consistent all the time.Design feature of the present invention: the work winding of two cophase counter parallel connections shares one group of iron core, and this new structure can reduce quantity unshakable in one's determination significantly.
The present invention is applicable to the external attached type autotransducer that is independent of outside the rectifier transformer fuel tank, also is applicable to the built-in formula autotransducer that shares same fuel tank with rectifier transformer.
Technique effect of the present invention is: 1. because cophase counter parallel connection two branch road work windings (copper bar) share an iron core group, can reduce the iron core quantity of half like this, save manufacturing cost; 2. two branch road work windings (copper bar) share one group of iron core group, reduce the iron core quantity of half and can improve autotransducer overall structure stability; Noise also is reduced; 3. reduce core material (silicon steel sheet) consumption, can reduce the loss of autotransducer; Improve the economic benefit of autotransducer.
