CIRCUIT ARRANGEMENT FOR SUPPRESSING AN ARC OCCURRING OVER A CONTACT GAP OF A SWITCHING MEMBER

摘要

The disclosure relates to a circuit arrangement for suppressing an arc occurring during a switching process, wherein a current bypass path comprises a PTC resistor connected in series with a fuse. The current bypass path is provided in parallel with a switch. The disclosure also relates to a photovoltaic power plant with a photovoltaic generator which is connected to an inverter via DC lines. In this arrangement, such a circuit arrangement is arranged in at least one of the DC lines.
