The outside for being set in the iron core column of group and low pressure winding successively staggeredly, the low pressure winding include at least one coiling list
Member, the coiling unit are arranged in parallel along the short transverse of the iron core column successively, wherein, each coiling unit includes phase
Several line cakes being mutually set up in parallel, several described line cakes are formed by wire continuous coiling.
Further, it is additionally provided with heat radiation oil duct between the iron core column and the low pressure winding, the heat radiation oil duct is along institute
The short transverse for stating iron core column is distributed vertically.
Further, the height of the length of the heat radiation oil duct and the iron core column matches.
Further, the coiling unit includes being mutually juxtaposed the two line cakes or four line cakes of setting.
Further, it is additionally provided with an insulating barrier between two adjacent coiling units.
The beneficial effects of the utility model are：By by wire continuous coiling into several line cakes, by several line cakes
A coiling unit is formed side by side, and the quantity of coiling unit in parallel is then determined according to the size of current of low pressure winding, so as to
In the winding process of low pressure winding, the number of conductors that single coiling unit uses is greatly reduced, and then reduce worker
Operation difficulty, improve production efficiency.

In the winding process of group, the number of conductors that single coiling unit 21 uses is greatly reduced, and then reduce the operation of worker
Difficulty, improve production efficiency.
In the utility model, in order to effectively be radiated to transformer, the service life of transformer, iron core column are improved
Heat radiation oil duct 4 is additionally provided between 3 and low pressure winding 2, short transverse of the heat radiation oil duct 4 along iron core column 3 is distributed vertically.Heat radiation oil duct
4 mainly guide and spread to the heat of the high hot-zone in the outside of iron core column 3, so as to improve the integral heat sink efficiency of transformer.
In the utility model, in order to ensure optimal radiating effect, the length of heat radiation oil duct 4 and the height phase of iron core column 3
Matching.
Preferably, the coiling unit 21 in the present embodiment includes being mutually juxtaposed the two line cakes or four line cakes of setting.Its
In, the quantity of each center line cake of coiling unit 21 can be also combined according to actual conditions.
Preferably, in order to improve the insulating properties between coiling unit 21, the safety in utilization of transformer is improved, adjacent two
An insulating barrier 5 is additionally provided between individual coiling unit 21.
More than, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited thereto,
Any change or replacement expected without creative work, should all cover within the scope of protection of the utility model.Therefore,
