Abstract
The utility model discloses a kind of three-phase transformer of band pair iron core, including iron core, primary coil, secondary coil and fixing piece；It is characterized in that：The iron core includes main iron core and secondary iron core；The primary coil, which is wound on main iron core, forms primary line bag；The pair iron core is located at the outside of primary line bag, and the central shaft of the pair iron core and primary line bag is mutually parallel；The primary line bag and secondary iron core form the iron core around the home of secondary coil；The secondary coil is wound on above-mentioned iron core around the home；Insulating layer is provided between the primary coil and secondary coil.By using above-mentioned technical proposal, the three-phase transformer of above-mentioned band pair iron core is on the basis of conventional three-phase transformer, add secondary iron core, so during around the home, the process around the home of primary coil is constant, but be wound on primary coil on the iron core around the home of primary line bag and secondary iron core composition, it can so improve utilization rate of the primary coil to magnetic flux；The final work efficiency for improving transformer.
Description
Technical field
The utility model is related to transformer technology field, more particularly to a kind of three-phase transformer of band pair iron core.
Background technology
Transformer (Transformer) is the device for changing alternating voltage using the principle of electromagnetic induction, main member
It is primary coil, secondary coil and iron core (magnetic core).Major function has：Voltage transformation, current transformation, impedance are converted, isolated, is steady
It presses (magnetic saturation transformer) etc..It can be divided into, according to use,:Power transformer and special transformer (electric furnace change, rectification change, power frequency examination
Test transformer, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformation
Device, electronic transformer, reactor, mutual inductor etc.).
Traditional three-phase transformer mainly includes iron core, primary coil, secondary coil and fixing piece；Wherein, primary line
Circle is wound on iron core, and secondary coil is wound on primary coil；Two coils share an iron core, in recent years, with society
Fast development, effect of the transformer in the production activity of the mankind is more and more important, therefore, how to improve the work of transformer
Efficiency, the volume and weight of reduction transformer are always an important directions of transformer research and development.
Utility model content
The technical problems to be solved in the utility model is：A kind of three-phase transformer of band pair iron core is provided；Band pair iron core
Three-phase transformer by increasing secondary iron core, and then improve utilization rate of the secondary coil to magnetic flux, and then improve transformer
Work efficiency reduces the volume of transformer.
The utility model is adopted the technical scheme that solve technical problem present in known technology：
A kind of three-phase transformer of band pair iron core, including iron core, primary coil, secondary coil and fixing piece；Its feature
It is：The iron core includes main iron core and secondary iron core；The primary coil, which is wound on main iron core, forms primary line bag；The pair
Iron core is located at the outside of primary line bag, and the central shaft of the pair iron core and primary line bag is mutually parallel；The primary line bag and pair
Iron core forms the iron core around the home of secondary coil；The secondary coil is wound on above-mentioned iron core around the home；In the primary coil and
Insulating layer is provided between secondary coil.
The utility model has the advantages and positive effects of：
By using above-mentioned technical proposal, the three-phase transformer of above-mentioned band pair iron core is on the basis of conventional three-phase transformer
On, secondary iron core is added, so during around the home, the process around the home of primary coil is constant, but by primary coil around the home
On the iron core around the home of primary line bag and secondary iron core composition, utilization rate of the primary coil to magnetic flux can be so improved；Finally
Improve the work efficiency of transformer.

Specific embodiment
For that can further appreciate that the utility model content of the utility model, feature and effect, the following examples are hereby given, and
It is described in detail with the accompanying drawings as follows：
Please refer to Fig.1 to Fig.4, a kind of three-phase transformer of band pair iron core, including iron core, primary coil, secondary coil with
And fixing piece；The iron core includes main iron core 1 and secondary iron core 2；The primary coil, which is wound on main iron core 1, forms primary line
Bag；The pair iron core 2 is located at the outside of primary line bag, and the central shaft of the pair iron core and primary line bag is mutually parallel；It is described first
Grade line bag and secondary iron core form the iron core around the home of secondary coil；The secondary coil is wound on above-mentioned iron core around the home；Described
Insulating layer is provided between primary coil and secondary coil.
By using above-mentioned preferred technical solution, the three-phase transformer with secondary iron core is on the basis of conventional three-phase transformer
On, secondary iron core is added, so during around the home, the process around the home of primary coil is constant, but by primary coil around the home
On the iron core around the home of primary line bag and secondary iron core composition, utilization rate of the primary coil to magnetic flux can be so improved；Finally
Improve the work efficiency of transformer.
The embodiment of the utility model is described in detail above, but the content is only the preferable of the utility model
Embodiment, it is impossible to be construed as limiting the scope of the utility model.It is made according to the scope of application of this utility model equal
Deng variation and improvement etc., should all still belong within the patent covering scope of the utility model.
