The trifid rectifier transformer has the advantages of reduced loss and reduced number of the system rectifier transformers, can reduce the occupied area of the rectifier transformer, and has better economic and social benefits.
Description
Technical field
The utility model relates to electrical equipment technical field, is specifically related to a kind of supporting tripartition rectifier transformer of ac variable frequency speed regulation that is.
Background technology
Along with applying of ac variable speed technology, supporting with it rectifier transformer demand constantly increases, and the user is also more and more higher to the requirement of rectifier transformer.At present, the common AC variable-frequency speed regulation system of three loads normally being added a double winding rectifier transformer by three double winding rectifier transformers or two division rectifier transformers forms.Common AC variable-frequency speed regulation system exists following shortcoming: 1, employed number transformer is many; 2, total losses are big; 3, occupation area of equipment increases and is twice.
For overcoming above-mentioned shortcoming of the prior art, the utility model proposes a kind of new solution.
The utility model content
Technical problem to be solved in the utility model is: how a kind of tripartition rectifier transformer is provided, this transformer not only has the energy-conservation advantage that reduces the wastage, reduces system transformer quantity, and can significantly reduce occupation area of equipment, be used for milling train, blower fan, the frequent load of pump class change can obtain better economic and social benefit.
To achieve the above object of the invention, the technical scheme that the utility model adopted is: a kind of tripartition rectifier transformer is provided, is made up of iron core, winding, secondary winding, device body, lead-in wire and an annex; The three-phase three-column structure of described iron core for adopting high many seams of magnetic conduction cold-rolled orientation silicon steel sheet stack to become, silicon steel sheet is by channel-section steel folder up and down and draw screw rod to connect into an integral body; Overlap once winding and secondary winding on the iron core column of described iron core from inside to outside successively; Be provided with the ground connection screen between a described winding and the secondary winding; It is characterized in that: a described winding is multilayer laminar or pie winding, and axial split is three parts, and three parts are connected in parallel; Described secondary winding adopts pie winding, and axial split is the electric three separate parts that; Described three phases winding at primary side adopts star or triangle to connect; Described secondary side three phase windings adopt star or triangle to connect respectively, can be with three different loads.
According to tripartition rectifier transformer provided by the utility model, it is characterized in that: the winding of adjacent part around on the contrary between three parts on the described axis of winding.
In sum, tripartition rectifier transformer provided by the utility model has following advantage:
1, the secondary winding axial split is the electric three separate parts that, and can reach the effect of the many confessions of a machine with three different loads;
2, not only have advantage energy-saving and cost-reducing, minimizing system transformer quantity, and can significantly reduce occupation area of equipment;
3, be used for milling train, blower fan, the frequent load of pump class change can obtain better economic and social benefit.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this tripartition rectifier transformer is made up of iron core, winding, secondary winding, device body, lead-in wire and an annex; The three-phase three-column structure of described iron core for adopting high many seams of magnetic conduction cold-rolled orientation silicon steel sheet stack to become, silicon steel sheet is by channel-section steel folder up and down and draw screw rod to connect into an integral body; Overlap once winding and secondary winding on the iron core column of described iron core from inside to outside successively; Be provided with the ground connection screen between a described winding and the secondary winding; It is characterized in that: a described winding is multilayer laminar or pie winding, and axial split is three parts, and three parts are connected in parallel; Described secondary winding adopts pie winding, and axial split is the electric three separate parts that; Described three phases winding at primary side adopts star or triangle to connect; Described secondary side three phase windings adopt star or triangle to connect respectively.
The winding of adjacent part around on the contrary between three parts on the above-mentioned axis of winding.As shown in Figure 2, first side winding A1-X1 be a left side around to, A2-X2 be right around to, A3-X3 be left around to.Arranging like this and make X1-X2, is equipotential between the A2-A3, and with traditional A1-X1, A2-X2, A3-X3 have samely saved raw material around to than the voltage that has reduced between the two adjacent groups winding, have improved the winding electric property; Described secondary winding adopts pie winding, and axial split is the electric three separate parts that, and adopts star or triangle to connect respectively, can be with three different loads.Be provided with ground connection screen ground connection between a described winding and the secondary winding, avoided like this because the overvoltage that the coupling capacitance between primary side and secondary side and the iron core forms at secondary side to the damage of secondary side rectifier cell.
An above-mentioned winding connects into star or triangle, and head end A, B, C draw; Secondary winding connects into star or triangle, and head end a1, a2, a3, b1, b2, b3, c1, c2, c3 draw respectively; Constituted the lead-in wire assembling of transformer jointly.
In sum, tripartition rectifier transformer of the present utility model adopts high many seams of magnetic conduction orientation silicon steel sheet stack to become the three-phase three-column closed magnetic loop, constitutes the magnetic loop of transformer.A winding, secondary winding is inserted in the three-phase three-column iron core respectively, and one time winding connects into star or triangle, and secondary winding connects into star or triangle, constitutes the circuit part of transformer.
But; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection range of the utility model claim.
