ELECTRICAL CHARACTER
EXCITATION SYSTEM:
AVR:SX440, SX460, MX321, MX341
The main stator supplies power to the exciter stator via the AVR.The efficiency semi-conductors of the AVR ensure building-up voltage by low residual magnetism of the magnet steel.The excitor rotor output is provided to the main rotor by a three-phase full wave bridge rectifier.This rectifier is protected by a surge suppressor against surges ecused by short circuit or lost synchronization.voltage regulation of SX440 AVR with three phase induction detecting module <±0.5.MX321 and MX341 suitable for the generator with permanent magnetic generator(PMG)
INSULATION AND VARNISH:
The insulation system is class H.
All wound components are impregnated with materials and processes designed specifically ensure the generator running in dreadful conditions.The special developed resin materials meet required for high mechanical of windings and rotating components.
WINDINGS AND ELECTRICAL PERFORMANCE:
All generator stators are wound to 2/3 pitch.This eliminates triple(3rd,9th,15th...)harmonics on the voltage waveform and is an optimum designed for UPS equipment of non linear loads.The 2/3 pitch design avoids excessive neutral currents result from higher winding pitches.A fully consecutive damper winding reduces oscillations during paralleling.The 2/3 pitch windings and carefully selected pole and tooth ensures very low waveform distortion.
TERMINALS AND TERMINAL BOX:
Stardard generators are 3-phase,and you can reconnect 12 ends of the terminals,which are mounted on a terminal block at the non-drive end of the generator.A sheet steel terminal box within AVR is provided with enough place for the customers' wiring.It has removable panels for easy access.
TELEPHONE INFLUENCE FACTOR:
THE(BS EN60034-1)<2%
TIF(NEMA MG1-22)<50
MECHANICAL FEATURES
SHAFT AND KEY:
All generator rotors are dynamically balanced to better than minimum vibration of BS6861:partI grade 2.5.Double bearings generators are balanced with a half key.
ENGINE ADAPTOR AND COUPLING
All generators are designed two kinds of construction.The adaptor and the drive plate is consonant with SAE standard.
LEVELS OF PROTECTION:
All generators are IP21,also IP23 and IP44 is an option,but rated power will decrease 5～10%
FEATURES:
·Accord with all leading standards
·H class insulation ensure the generator running in dreadful conditions
·The 2/3 pitch design avoids excessive neutral currents
·You can reconnect 12 ends of the terminals to meet other voltage
·Single bearing or double
·Easy to install and maintenance
·Standard IP21
OPTION AND ACCESSORY:
·Windings temp protect thermistor and replay
·PMG
·MX321 or MX341
·Transformer for droop during paralleling
