Description
Technical field
The utility model is related to a kind of transformer, more particularly to a kind of transformer changing from three phases to single phase.
Background technology
Transformer Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, original three-phase
The mode that the transformer for becoming single-phase is all made of three two line packets of column makes and connects into single-phase transformer, wherein intermediate iron core
Column is vacant, does not form magnetic circuit, and the transformer for causing three phase transformations single-phase is less efficient in the process of running, and between three-phase
Degree of unbalancedness it is larger.
Utility model content
The technical issues of the utility model solves is to provide a kind of single-phase change of three phase transformation of one kind reducing tri-phase unbalance factor
Depressor.
Technical solution adopted by the utility model to solve its technical problems is：A kind of transformer changing from three phases to single phase, including
The both sides of three silicon steel columns made of being stacked by silicon steel sheet, the three silicon steel column upper and lower ends are provided with apparatus for fixing transformer, institute
The apparatus for fixing transformer for stating both sides is fixedly connected by fixing device, and the three silicon steel column upper and lower ends are connected to one by iron yoke
It rises, around wired packet on three silicon steel columns, the line packet includes main coil and secondary coil, the main coil tail of three silicon steel columns
Hold parallel with one another, three groups of secondary coils are connected with each other, and further include the connecting terminal being connect with the end of main coil and secondary coil.
It is further：The tail end of series connection or three groups of secondary coils is in parallel from beginning to end successively for three groups of secondary coils.
The utility model has the beneficial effects that：The transformer changing from three phases to single phase of the utility model uses three columns, three line inclusion
Structure makes each iron core column, each coil have corresponding magnetic circuit to pass through, when transformer is transformer production when phase three-wire three job contract is made
Raw magnetic circuit is identical, and the shortcomings of tri-phase unbalance factor is larger and working efficiency is low is not present.
Description of the drawings
Fig. 1 is transformer changing from three phases to single phase schematic diagram.
In figure label for：Silicon steel column 1, apparatus for fixing transformer 2, fixing device 3, line packet 4, connecting terminal 5.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
A kind of transformer changing from three phases to single phase as shown in Figure 1, including three silicon steel columns 1 made of being stacked by silicon steel sheet, institute
The both sides for stating three 1 upper and lower ends of silicon steel column are provided with apparatus for fixing transformer 2, and the apparatus for fixing transformer 2 of the both sides is filled by fixed
It sets 3 to be fixedly connected, the fixing device 3 is bolt, screw etc., and three silicon steel columns, 1 upper and lower ends are connected to by iron yoke
Together, around wired packet 4 on three silicon steel columns 1, the line packet 4 includes main coil and secondary coil, the master of three silicon steel columns 1
Coil tail end is parallel with one another, and three groups of secondary coils are connected with each other, and further include the terminals being connect with the end of main coil and secondary coil
Son 5, when work, the main coil front end connection external high pressure input electricity of three silicon steel columns 1, three groups of secondary coils to pick out a connection outer
Portion low-voltage output cord road, three groups of secondary coils using three line packets 4 concatenate or and by the way of connecing, such as：The first place of three groups of secondary coils is connected,
Then each tie point be three groups of secondary coils pick out a little or the tail end of three groups of secondary coils is in parallel, then before three groups of secondary coils
End is that external outlet line picks out a little, and when there is electric current to flow through main coil, silicon steel sheet generates magnetic circuit, due to electromagnetic induction principle,
So that secondary coil generates opposite voltage and current, since the single-phase transformer of this three phase transformation uses three columns, three line packet, 4 structure, make
Each iron core column, each coil have corresponding magnetic circuit to pass through, and make three magnetic circuits that can balance, to improve the work of transformer
Make the tri-phase unbalance factor of efficiency and transformer.
Particular embodiments described above has carried out into one the purpose of this utility model, technical solution and advantageous effect
Step is described in detail, it should be understood that the foregoing is merely specific embodiment of the utility model, is not limited to this
Utility model, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should all wrap
Containing being within the protection scope of the utility model.
