Sectional drives give more from less: The use of sectional drives sharing a common DC bus has reduced the likelihood of overloads on centrifuges used by British Sugar

摘要

At British Sugar's Newark factory, MultiDrives from ABB are being [used to drive three centrifuge inits, which spin off sugar crystals from solution. Using a DC bus system, all the inverter sections for each centrifuge are supplied from the same common DC bus, which itself is supplied from the common regenerative rectifier. Sectional drives sharing a common DC bus can offer a cost-effective option in applications at larger powers, from about, 100 kW, DC bus drives use common components to control and supply power to the inverter sections of AC drives, reducing costs. A single rectifier can supply several inverter sections from a common DC bus, rather than using one rectifier per inverter as is the case with standalone units. Up to 25% less space is needed owing to the smaller components count.
