FIELD: electricity.
SUBSTANCE: invention is related to an on-load tap charger with semiconductor switching elements for uninterrupted switching between fixed contacts of the tap charger which are connected electrically to the tapped winding of the tapped transformer. Each of the fixed contacts of the tap charger can be connected to the device for charging either directly or through interconnected semiconductor switching elements. According to the invention the tap charger has separated and fixed tapping contacts for electric insulation of the semiconductor switching elements from the transformer winding during the static mode of operation.
EFFECT: excluding high load of switching elements and guaranteeing electrical separation of the tap charger from the transformer winding in the static mode of operation.
