Backing plate 10 adopts insulating board or slabstone, for reducing the loss of transformer type controlled reactor device, when controling winding capacity will
When asking leakage field gap larger, should ensure that capacity increases leakage field gap number in the case of constant, so that each leakage field gap length subtracts
Few.
Magnetic coupling between described adjacent controling winding is passed through middle iron core and connects to separate to reduce, controling winding iron core and right
The magnetic leakage iron core parallel connection answered makes magnetic leakage iron core during controling winding short circuit play a point magnetic action, thus short-circuit impedance can be made to reach
100%.The short-circuit impedance value of controling winding unit can be made by the difference controlling leakage field gap length or number in magnetic leakage iron core
Difference, and then it is different to realize each controling winding unit compensation capacity.For reducing the loss of transformer type controlled reactor device,
When controling winding capacity requirement leakage field gap is larger, should ensure that capacity increases leakage field gap number in the case of constant, so that often
