CIRCUIT ARRANGEMENT FOR A PHOTOVOLTAIC INVERTER FOR BREAK RELIEF USING SHORT-CIRCUIT SWITCHES, AND USES OF THE CIRCUIT ARRANGEMENT |
摘要 |
A circuit arrangement for a photovoltaic inverter includes two bus lines, input terminals for connecting at least one photovoltaic generator to the bus lines, respectively, and at least one DC/AC converter connected to the bus lines. The circuit arrangement further includes a disconnector between each DC/AC converter and the bus lines, respectively, and at least one short-circuit path for short-circuiting a voltage between the bus lines, wherein a short-circuit switch is arranged in the short-circuit path, wherein the at least one short-circuit path runs between the bus lines upstream of all disconnectors between the input terminals and the disconnectors, and wherein the short-circuit switch in the at least one short-circuit path between the bus lines is connected in series with a fuse. Still further, the circuit arrangement includes at least one further short-circuit path for short-circuiting the voltage between the bus lines, wherein a short-circuit switch likewise is arranged in the at least one further short-circuit path |
