Description
Technical field
The present invention relates to design of transformer manufacturing field, more particularly to a kind of loaded capacity-regulated transformer machine body structure.
Background technology
Loaded capacity-regulated transformer is that one kind has two kinds of rated capacities of size, and two kinds of capacity can be with the distribution of automatic conversion
Transformer.The transformer passes through loaded capacity-regulated switch using high pressure winding Y-D conversions, the conversion regime of low pressure winding series and parallel
Realization automatically adjusts to transformer capacity size.Because of low pressure winding connection in series-parallel requirement, umber of turn is divided into two parts, totally 4
Lift one's head, be wound in the arrangement of space and be difficult to realize using copper foil, it is use 3 layers of drum type brake winding structure to be easy to operate more, i.e., 1
Individual to lift one's head positioned at winding bottom, another 3 are lifted one's head positioned at winding top.But because winding conducting wire section is big, radical in parallel is more, and lift one's head
Locate stress relatively to concentrate, for transformer under short-circuit electromotive force effect, top, which is lifted one's head, easily loosens resilience, causes axis of winding deformation to lose
Surely.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of loaded capacity-regulated transformer machine body structure, using four layers of circle
Core structure, whole each two groups of low pressure winding upper and lower part are lifted one's head, avoided because of stress concentration of lifting one's head, and are acted in short-circuit electromotive force
Lower loosening resilience, the influence to caused by winding axial stability；And it is segmented and is clamped with conductor grip, it is ensured that lead acts in short-circuit force
Under do not deform and displacement, improve overall device body mechanical strength.
The technical solution adopted for the present invention to solve the technical problems is：A kind of loaded capacity-regulated transformer machine body structure, it
Including low pressure winding；The low pressure winding is four layers of cylinder mode, wherein one layer is to lift one's head and common portion in common portion
Under lift one's head, another three layers are to lift one's head and lift one's head with connection in series-parallel part on connection in series-parallel part；Lift one's head in the common portion and connection in series-parallel
Lift one's head on part and be connected by copper bar or cable with the switch of side with device；Lift one's head under the common portion with connection in series-parallel part
Lift one's head also by copper bar or cable lead to device body top and upside switch connect；Lift one's head and connection in series-parallel under connection common portion
The center section on copper bar or cable lifted one's head under part is gripped by segmented conductor line；Lift one's head in connection common portion,
That lifts one's head under common portion, lifts one's head on connection in series-parallel part and lift one's head under connection in series-parallel part is located at device on the copper bar or cable of side
Gripped commonly through total conductor grip.
Beneficial effects of the present invention：A kind of loaded capacity-regulated transformer machine body structure of the present invention, using four layers of drum type brake knot
Structure, whole each two groups of low pressure winding upper and lower part are lifted one's head, avoided because of stress concentration of lifting one's head, and are loosened under short-circuit electromotive force effect
Resilience, the influence to caused by winding axial stability；And it is segmented and is clamped with conductor grip, it is ensured that lead is not sent out under short-circuit force effect
The shape that changes and displacement, improve overall device body mechanical strength.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of loaded capacity-regulated transformer machine body structure.
Embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and further retouched in detail
