Cara Kerja KINOLT Dynamic UPS

 

Bagian-bagian dari Stato-Alternator terdiri dari :

Elektromagnetical Clutch - kopling magnet-elektro yang akan menggabungkan poros dalam (inner rotor) stato-alternator ke mesin diesel pada saat terjadinya power failure sehingga alternator mendapat daya dari mesin diesel.

Kinetic Energy Accumulator - dengan drum yang berputar bebas (warna oranye) menyimpan energi kinetik yang dapat disalurkan ke "inner rotor" untuk memutar alternator menjembatani waktu listrik padam dan engine mulai berputar.

Synchronous Machine - adalah alternator untuk pembangkit listrik yang juga berfungsi sebagai sinkronus motor pada saat listrik PLN tersedia.

 

   How does it work?

In the heart of theNO-BREAK KS®‚ is its kinetic energy accumulator; a clever but simple system to store and retrieve kinetic energy.

The kinetic energy accumulator consists of two rotating parts: the outer rotor runs mechanically-free around the inner rotor. (See diagram below)

The inner rotor, driven by the main shaft, rotates at 1500 rpm (50 Hz) or 1800 rpm (60 Hz). It contains two sets of windings; a three-phase AC winding and a DC winding.

   Energy storage

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.

The  outer rotor stores kinetic energy advantageously, since the amount of kinetic energy increases quadratically with the distance from the centre of rotation.


   Energy retrieval

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.

The kinetic energy accumulator is a totally brushless system.
