Abstract (en)
[origin: WO8402224A1] The secondary winding (15) and the coal body (14) which carries it are designed as chambers; the radial expansion (height) of each chamber winding (29) decreases as the chamber potential increases according to the geometrical series law, so that the insulation interval (30, 31) between the secondary winding (15) and the areas of the ignition coal, which induce a lower potential, increases as the chamber potential increases. This enables to reduce the volume and the weigth of the ignition coal for an identical electric power.
