Description
Technical field
The present invention relates to transformer technology field more particularly to a kind of ZPSC type phase-shifting rectifier transformers.
Background technique
Phase-shifting rectifier transformer is one kind of rectifier transformer, is both a kind of important factories and miness electrical equipment, also can conduct
The precision instrument of measuring room and laboratory.
Rectifier transformer is the power transformer of rectifier equipment.The characteristics of rectifier equipment is original side's input AC, and pair side
By exporting direct current after rectifier element.Unsteady flow is the general name of three kinds of rectification, adverse current and frequency conversion working methods, and rectification is wherein to apply
It is widest a kind of.Transformer as fairing power supply is known as rectifier transformer.Industrial rectification DC power supply is big
Part is passed through obtained from rectifier transformer and rectifier equipment as AC network.
The mating high-voltage frequency converter of dry type phase-shifting rectifier transformer uses, and country's products with larger capacity mostly uses secondary more at present
Electromagnetic wire parallel way coiling.With the increase of transformer capacity, parallel conducting wire radical also increases, and meets transformer temperature rise with this
With the demand of loss.When the capacity of transformer increases, need conducting wire in parallel that can also be continuously increased, due to depositing between parallel conducting wire
Difference in terms of inductance and heat transfer causes the electric current of parallel conducting wire phase that can have increasing difference with radical increase in parallel
Not, to cause the imbalance of the temperature rise of transformer.There is the region of overheat in transformer, influence transformer service life and transformation
The fan-out capability of device, meanwhile, the weaker disadvantage of overload capacity existing for transformer, and coil is consolidated in low-voltage coil coiling
It is fixed ineffective, it is be easy to cause sideslip of starting, influences product quality, therefore, in this background, we will not only possess safety
Reliable product quality, and the high-effect of transformer will also become indispensable advantage.
Such as application No. is: 201420868267.8 Chinese patent discloses a kind of dry type phase-shifting rectifier transformer,

Coil windings include several line cakes disposed in parallel, and combed stay is set to outside insulating cylinder, support each line cake；The line cake is copper
Foil or aluminium foil, each line cake are wound on combed stay.The dry type phase-shifting rectifier transformer that the utility model proposes, solves existing change
The even situation of current unevenness in depressor operational process.The utility model transformer makes coil using copper (aluminium) foil, eliminates
Insulation between electromagnetic wire, is uniformly distributed electric current on winding.Foil relatively thin simultaneously can reduce the excellent of stray loss
Gesture further decreases loss and temperature rise；But the transformer overload ability in the technical solution is weaker, disposable short-circuit impedance compared with
It is small, it is easy that transformer is caused to damage.
It for example discloses a kind of low-voltage coil application No. is: 201220691545.8 Chinese patent again to lift one's head, feature
It is: including pressing plate, offers strip groove on the inside of the pressing plate, low-voltage coil is provided in the strip groove, it is described low
Crimping circle includes the conducting wire of several horizontal alignment helically coilings, and the conducting wire by internal coil diameter side hangs down with the conducting wire by coil outer diameter side
Straight setting；Low-voltage coil disclosed in this application, which is lifted one's head, to be designed rationally simply, and the conducting wire of horizontal alignment helically coiling passes through in pressing plate
The strip groove of side is fixed, and sound construction is reliable, reduces the thickness of pressing plate, is reduced the height of pressing plate, has been saved raw material
Use, pressing plate stress is bigger, not cracky, and service life is longer, but the technical solution mesolow winding protruding head is using single
A circular pressing plate be easy to cause the phenomenon that starting sideslip in coiling.
