  "textContent": "The invention relates to a heating system for electrically driven vehicles, in particular for vehicles supplied with overhead line voltage; with an electrical resistance (1) supplied with current; with an insulating fluid circuit (2); with a heat exchanger (3); with a heating medium circuit (4); the electrical resistance (1) is switched into the insulating fluid circuit (2) such that heat energy generated in the electrical resistance (1) is transferred to the insulating fluid; the insulating fluid circuit (2) and the heating medium circuit (4) are interconnected by means of the heat exchanger (3) such that heat transfer from the insulating fluid circuit (2) to the heating medium circuit (4) takes place; the heat exchanger (3) is connected to the electrical potential of the vehicle chassis; the insulating fluid circuit (2) is isolated relative to the heat exchanger (3) such that it is at a different electrical potential than the heat exchanger (3); the electrical resistance (1) is suspended in an isolated manner relative to the vehicle chassis such that it is at a different electrical potential than the insulating fluid circuit (2).",
