Abstract
The invention relates to an energy supply system for a mobile resistance welding machine for flash-butt welding of track rails, comprising a combustion engine (1) coupled to a generator (2) as well as a charging device (5) for charging an energy store (7), wherein the energy store (7) is a buffer element of an intermediate circuit (13) to which a welding inverter (14) is connected. In this, the energy supply system comprises an island grid to which the generator (2) is connected and which is coupled to the intermediate circuit (13) by a controlled power converter (16).
Claims9
