The quantity of two grooves is four.
A kind of above-mentioned combined transformer high-tension coil, wherein, the quantity of the unit coil is four.
The beneficial effects of the utility model are：
The power of the utility model each unit coil is the 1/4 of whole coil power, and it is electric that electric property meets 10KV
Performance, during mounting coil, two the first projections of adjacent unit coil, the first groove coincide be set with up and down, then with folder and briquetting
It is electrically connected between fastening, adjacent cells coil, completes assembling；Coil electric effect after assembling is equal to integrated poured coil,
But there is the heat-dissipating space of 5-10mm between unit coil.
Unit coil is highly low, is the 1/4 of whole coil, during cast, in the absence of because coil height it is high, mould is high, true
There is bubble to arrange unnet situation under dummy status in molded coil, improve electric property；
Such as there is making defective work, or follow-up operation local fault, then the waste of material for causing is small or after-sales service
Service is convenient, fast, only changes the unit coil of same area；
The ventilation effect of the high-tension coil power component being made up of unit coil of dry-type transformer, because coil-end up and down
There is the space length of 5~10mm between face, thus area of dissipation improves 20%, so as to significantly reduce high-voltage power coil
Running temperature.Improve the service life of transformer.
