2 CONFIGURATION AND SCOPE OF SUPPLY

G E N E R A L

The generator is designed to operate together with a gas engine.

CONSTRUCTION

The stator frame is a rigid welded steel structure construction. The stator core is built of thin electric sheet steel laminations which are insulated on both sides with heat-resistant inorganic resin. The radial cooling ducts in the stator core insure uniform and effective cooling of the stator.

The rotor consists of a shaft poles fixed on the shaft, exciter and a fan(s). The shaft is machined of steel forging. The poles are manufactured of 2 mm sheet steel and bolted from the top to the shaft. The pole laminations are pressed together with steel bars which are welded to the end plates. The exciter rotor and the fan are shrink fitted onto the shaft and secured with a key.

Ail windings are completely vacuum pressure impregnated with high quality epoxy resin. The windings are provided with very strong bracing which withstands ail expected mechanical and electrical shocks and vibrations as well as chemicals. For more information ask for brochure "MiCADUR-Compact industry insulation System"

The stator frame, core support and endshieids are made of fabricated steel and welded together. The stator frame is closed with steel panels that guide the ventilation air and provide the degree of protection required. The flange mounted bearings are bolted to the endshieids

According to iM1101 the machine has 2 bearings The feet are raised. Cyiindar shaft

FOUNDATION

The machine can be mounted using shimming, machined blocks, chock fast or on grouted sole plates or bed plate. Before using other mountings, contact us.

COOLING

The machine has a shaft mounted fan inside. The surrounding air is used for cooling. The cooling air is drawn in though air filters (self charging eiectrostatic panels) and blown out to the surrounding environment.

C O N T R O L S Y S T E M S

Brushless excitation. The excitation requires following components: Current transformers for booster excitation and actual value measurement. 2-core voltage transformer for measurement and excitation power supply.

4. Resistance measurement of windings and elements * 5. Direction of rotation, phase sequence 6. First running: checking of bearings * 7. No-ioad curve, U1 = f(im), n = nN 8. Short-circuit curve, 11 = f(im), n = nN 9. Tests with voltage regulator

- adjusting of basic settings [ Td'(O) = 4.0 s ] - Initial voltage buiid-up and voltage regulation speed at no-ioad - testing of voltage setting range - setting of under frequency limit and function testing - measuring of sustained short-circuit current - measuring of remanence voltage

10. Overspeed test, t = 1 min, n = 1.25 x nN = 900 rpm 11. Vibration measurement at no-ioad, U1 = U1N, n = nN

- 0 ~> peak, mm/s 12. High voltage test:

stator winding 30600 V 50 Hz, 1 min rotor winding 2500 V 50 Hz, 1 min fieid winding 2000 V 50 Hz, 1 min space heaters 1500 V 50 Hz, 1 min Pt-100 (stator) 1500 V 50 Hz, 1 min Pt-100 (others) 500V 50 Hz, 1 min

13. insulation resistance measurement polarization index of stator windings (lOmin / 1 min)

* Tests to be completed before witness tests (Performing order of the tests may differ from the listed above.)

S U R F A C E T R E A T M E N T

Colour: RAL5019 Grade: P I - Paint System 1, norm

The surface treatment of the machines is based on epoxy paint system, which includes solvent free topcoat. This paint system is suitable especially for urban and industrial atmospheres with moderate corrosive attack (ISO 12944-2, C2 and C3 without direct UV-radiation). Total film thickness is 180 um.
