Shanghai Dongfeng 620 kVA Diesel Generator

Shanghai Dongfeng 620 kVA Diesel Generator

When the mains supply drops, the capacity of the standby source decides how long production lines, cooling systems and critical loads keep running. The Shanghai Dongfeng 620 kVA diesel generator is built around exactly that requirement: standby power (ESP) is rated at 620 kVA / 496 kW and prime power (PRP) at 560 kVA / 448 kW. At a power factor of 0.8 the set supplies 895 A in standby duty and 808 A in continuous operation.

Engine

Power comes from an SDEC diesel engine with 12 cylinders in a V type layout and a total displacement of 25.8 litres. Bore and stroke measure 135 x 150 mm and the compression ratio is 16:1. The turbocharged aftercooled intake pressurises the combustion air and cools it before combustion. Fuel consumption is stated as 128 L/h at full load and 96 L/h at 75 percent load.

Alternator and Electrical Data

The alternator runs at 400/230 V and 50 Hz in a three-phase configuration, with a power factor of 0.8. Windings use class H insulation and the enclosure carries IP23 protection. The 400 V three-phase and 230 V single-phase values allow mixed consumers to be fed from one distribution board.
