摘要： Various embodiments of the teachings herein include a DC network comprising: an electrical conductor; a switching unit arranged at one end of the conductor to break the electrical connection via the conductor, the switching unit including a controllable power semiconductor connected in series in the current path of the conductor; wherein the conductor includes a first section and a second section starting from the switching unit with a connection point between the first section and the second section; a first overvoltage protection apparatus connected between the connecting point and a second pole of the DC network; and a second overvoltage protection apparatus connected between that end of the second section remote from the switching unit and the second pole. The overvoltage protection apparatuses each have a capacitor.
