Start of Diesel Engine or A Micro-turbine Based on WIMA Powerblocks
Starting of V16 or V24 cylinder motors(6000 kW), e.g. for a generator drive of diesel-electric trains or the start of diesel engines for vessels requires high currents;1300 A are quite usual (during the initial breakaway torque even considerably more) Frequently the crankshaft is turned from both sides by two starters(e.g.7 kW each with forced switch-off after 9 sec for 2 min) to avoid torsion of the big mass.
Because of their significant maintenance, service life, and weight benefits, WIMA:
PowerBlock Modules are more and more replacing customary starter batteries:
The construction principle of a motor starter with 333F and 28V nominal voltage
Pitch drive for wind power applications with 14F and 165V nominal voltage
The capacitor module is only about 1/10 in weight compared to a conventional battery solution and thus permits an increased operating distance of up to 25 % due to additional fuel that can be carried.
Recuperation of braking energy
Generally, a vast amount of kinetic energy is wasted when braking. This temporarily generated high energy can be stored by WIMA PowerBlock modules and be made available again when required.
