Abstract
(EN)
A tap changer is filled with an insulating liquid as well as devices for absorbing variations in the volume of the insulating liquid due to thermal conditions. A gas cushion is provided which is integrated into the tap changer vessel and is formed by members that absorb the variations in the volume of the insulating liquid by changing the shape thereof. Furthermore, a gas cushion envelope is provided which prevents the gas of the gas cushion to be mixed with the gases generated by the thermal decomposition of the insulating liquid.
