Is it a generator? A UPS? A flywheel? The new backup power systems at colocation specialist FORTRUST bring these elements together. As FORTRUST expands its Denver data center, it will use Diesel Rotary Uninterruptible Power Supply (DRUPS) from E1 Dynamics to provide emergency power during utility outages. The DRUPS unit features a diesel engine and a rotary UPS that uses kinetic energy, eliminating the need for batteries.
Bien que ne faisant pas directement partie de l’aéronautique à proprement parler, la société EURO-DIESEL entretient néanmoins des liens étroits avec le secteur. Le plus évident est probablement le rôle essentiel joué par son produit phare auprès d’un de ses clients les plus importants: les aéroports & tours de contrôle du trafic aérien. Le très haut degré de technicité de ce produit le rend également comparable aux technologies de l’aéronautique. Nous avons rencontré Philippe Gillain, administrateur délégué d’EURO-DIESEL, qui nous explique les spécificités de cette entreprise liégeoise, et les profils qui contribuent à sa réussite.
EURO-DIESEL (UK) Ltd exhibited at Data Centre World 2016 at the London Excel on the 12-13 April. A major event in the Data Centre calendar - this year’s show was bigger and better than ever with over 250 exhibiting companies. With strong footfall to the EURO-DIESEL stand, the team were kept busy meeting new and existing contacts from across the industry.[+]
The first of eight 2500 kVA NO-BREAK KS®7e units’ arrived to its final destination in Singapore.
The NO-BREAK KS® is such a simple piece of equipment that one might think of it as a conventional generator-set. It is made up of a Diesel Engine that is coupled to a Stato-Alternator, via an Electromagnetic Clutch. The Stato-Alternator is the combination of a Kinetic Energy Accumulator and a Synchronous machine.
The NO-BREAK KS® also includes a control panel and a choke/power panel.
How does it work?
In the heart of the NO-BREAK KS®‚ is its kinetic energy accumulator; a clever but simple system to store and retrieve kinetic energy.
In conditioning mode, the AC winding is powered to generate a rotating magnetic field which turns the outer rotor to the speed of maximum 3000 rpm. However, the relative speed between inner and outer ring of the bearings is only 1500 rpm, since the shaft itself is rotating at 1500 rpm.
In independent mode, the DC winding is powered and the outer rotor is electrically coupled to the inner rotor by induction. Its kinetic energy is transferred to the inner rotor -- it drives it. This energy transfer is regulated by accurately controlling the current injected into the DC winding.
