DEVICE FOR COOLING A MAGNETIC BEARING OF A TURBINE BY MEANS OF A GASEOUS FLUID, TURBINE, AND METHOD FOR COOLING A MAGNETIC BEARING OF A TURBINE BY MEANS OF A GASEOUS FLUID

摘要

The invention relates to a device (10) for cooling a magnetic bearing (52) of a turbine (50) by means of a gaseous fluid (40), having a fluid supply line (20) for supplying the gaseous fluid (40) to the magnetic bearing (52), a fluid discharge line (21) for discharging the gaseous fluid (40) from the magnetic bearing (52), a conveying device (22) for conveying the gaseous fluid (40), and a drying apparatus (30) arranged in the fluid supply line (20) for drying the gaseous fluid (40). The invention further relates to a turbine (50), having a magnetic bearing (52) and an apparatus (10) for cooling the magnetic bearing (52) by means of a gaseous fluid (40) and to a method for cooling a magnetic bearing (52) of a turbine (50) by means of a gaseous fluid (40) using an apparatus (10) for cooling the magnetic bearing (52) by means of a gaseous fluid (40).
