Zusammenfassung: | The invention discloses a high-voltage direct-hanging energy storage converter and an on-site detection method, the converter comprises a plurality of commutation chains, the plurality of commutation chains form star connection or angle connection, and the three-phase AC output of the converter is connected with a power grid through a first AC switch. A second AC switch is connected between the AC output A phase and the AC output B phase, between the AC output B phase and the AC output C phase, and between the AC output C phase and the AC output A phase. According to the invention, star connection or angle connection is formed by the plurality of commutation chains, and the first AC switch and the second AC switch are arranged, so that when the converter is standby, whether main devices in the energy storage converter are normal can be verified by controlling the circulating current between the commutation chains, the test efficiency is high, and the operation difficulty is low.
