Description
Technical field
This utility model belongs to field transformer, especially relates to a kind of capacitance-adjustable transformer winding.
Background technology
Capacitance-adjustable transformer is that one has two capacity of size, can carry out the transformator of capacity allotment according to payload.Its fundamental design idea is: Three-Phase Transformer high pressure winding is connected into triangle (D) when Large Copacity, and low capacity is (Y).Every phase low pressure winding is made up of three parts: one is minority wire turn part (the Ith coil accounts for the 27% of the low pressure number of turn), most wire turns additionally formed (the IIth coil, the IIIth coil account for the 73% of the low pressure number of turn altogether) by two parts.During Large Copacity, the IIth coil and the IIIth coils from parallel connection of coils again with the Ith coils connected in series, during low capacity, the Ith coil, the IIth coil and the IIIth coil are all connected.When being adjusted to low capacity by Large Copacity, high pressure winding becomes Y connection and makes phase voltage reduce, but output voltage must remain unchanged, and makes output voltage constant by the way increasing low pressure umber of turn.
The low pressure winding of capacitance-adjustable transformer is made up of three parts, and how coiling is a difficult point.The winding method having had at present can be summarized as following several: one be the IIth coil with the IIIth coil width to dividing coiling, the shortcoming of this winding method is: when the IIth coil and the IIIth coils from parallel connection of coils are applied, because the resistance that two coil-induced magnetic fields are different and they have is different, there is very big circulation loss；Another kind is the IIth coil and the IIIth coil axial split coiling, and this winding method does not have a circulation loss, but the number of turn of the IIth coil and the IIIth coil is many but axial height is short, very bad winding displacement and coiling；Head end and tail end must together with lift one's head, limit the selection of the IIth coil and the IIIth coil number of plies；And the IIth coil and the IIIth coil each need transposition, have had more transposition width and the helical angle of one times, and space availability ratio is not high.
And Chinese patent CN102930964 discloses a kind of three-phase capacitance-adjustable transformer, it is by by the IIth section of coiling and the IIIth section of mode that coiling axially intersects and is wound on iron core, solving the problems such as high-low pressure ampere-turn is uneven, circulation loss is high, production efficiency increases.But have the disadvantage in that the transformator that capacity is big, the IIth section and the IIIth section will with multiple conducting wires and around, if the IIth section and the IIIth section vertically intersect and around need each self-transposition, remain the transposition width and helical angle that have had more one times；Wire is many, and each self-transposition is also cumbersome, bad liter layer, and production efficiency is still not high；And these shortcomings are with regard to its Producing reason, mainly use the result of wire coiling winding.
