TÜV Nord grants Huebner generator IEC 60079-0 /-15 Ex certification
The Ex permanent magnet three-phase synchronous generator from Huebner Giessen features IECEx certification.
TÜV Nord in Hanover, Germany – one of the world’s most respected IECEx certifica-tion authorities – has examined the generator’s explosion-proof qualities. It has con-firmed that the Huebner generator passed the type verification and tests on test de-vices. A TÜV Nord audit has additionally shown that the company has an effective quality management system in place. “This internationally recognised certification does not yet exist for permanent magnet generators, so this is a real breakthrough,” according to Professor Ewald Ohl, Head of Energy and Drive Systems at Huebner Giessen.
Ex-protected generator for gas liquefaction plants
The Ex-protected Huebner generator has now been used for the first time as a pilot exciter at a gas liquefaction plant. In gas liquefaction, the expansion of gas under pressure creates surplus energy as a by-product. This is fed into a gas-expansion turbine and a power generator to electrify the plant instead of emitting it into the envi-ronment. The pilot exciter from Johannes Huebner Giessen is used in this setting in black starts, an emergency start, to restore power following complete outages of the main electricity supply.
Through its rotating magnetic field, the pilot exciter induces voltage in the turbine of the main exciter, which supplies the power generator with the necessary exciter field and ensures that the emergency power system remains functional.
The main exciter will lose its remanence (remanent magnetisation) if a plant is idle for a longer period of time. As a result, the power generator will not have an exciter field during a complete outage of the main electricity supply and will not work properly. When this happens, a permanent magnet pilot exciter generator is needed. With every rotation of the turbine, the pilot exciter generates voltage and supplies the main exciter with a new magnetisation curve. By doing so, the pilot exciter guarantees the availability of the main exciter and ensures the power supply at all times.
Huebner has developed the generator especially for this application. Thanks to this new Ex-protected version, it can be used in gas liquefaction plants for the very first time. In addition, the DSGP 112.14-6 Ex has been coated with RAL 7035 worldwide, a seawater-resistant coating that makes it perfect for use in coastal locations. It has an ingress protection rating of IP 55 and Ex nA IIB T3 Gc explosion protection.
