MX 740 Frame Generators

l.OUTSTANDING ELECTRIC CHARACTERISTICS

• STEADY VOLTAGE REGULATION IS LESS THAN 0.5%.
• TRANSIENT VOLTAGE REGULATION IS LESS THAN +20%, -15%(60%IN,P.FW0.4LAG).
• VOLTAGE ADJUSTING RANGE IS OVER THAN 10% OF UN.
• TOTAL VOLTAGE WAVEFORM DISTORTION IS LESS THAN 5%(L-L)
• THE STEADY SHORT CIRCUIT IS N300%IN,AND MAINTAIN TIME 习OS
• IT HAS WIDE STABILITY RANGE AS USING IN NONLINEAR LOAD CONDITION.
• GOOD MOTOR STARTING CAPACITY.
• GOOD PARALLELING PERFORMANCE.

2.UNIQUE STRUCTURE

• FULL GUARDED SCREEN AND LOUVERS FOR OPERATOR SAFETY. UNIQUE VENTILATION AND COOLING MAY BE EFFICIENT HEAT TRANSFER AND GOOD WINDINGS COOLING.
• BRUSHLESS GENERATOR WITH PMG EXCITING SYSTEM. IT CAN PROVIDE 300% IN STEADY SHORT CIRCUIT CURRENT, AND MAINTAIN TIME 10S. IT HAS NOTTHE TROUBLE OF LOST RESIDUE MAGNETISM.
• SALIENT UNIROTOR CONSTRUCTION .ROTOR CORE CLOSLY COUPLED WITH DIE CAST DAMPING WINDING. THE FIELD WIN DINGS ARE LAYER WOUND WITH THERMOSETTING EPOXY FOR HIGH MECHANICAL AND ELECTRICAL INTEGRITY.
• DIGITAL VOLTAGE REGULATOR IS ENCAPSULATED FOR RELIABLE PERFORMANCE IN VARYING ENVIRONMENT SUCH AS PROTEOING MOISTURE AND ANH-VIBRATION.
• rrs VOLTAGE REGULATION HAS HIGH ACCURACY ABOUT 0.25%. IT INCLUDED ADJUSTABLE VOLTAGE, STABILITY AND VOLT/HERZ UNDER SPEED PROTECTION, THREE PHASE RMS SENSING, PARALLELING ,OVER EXCITION, OVERVOLTAGE PROTECTION AND SO ON AS STANDARD. (DETAILS SEE DIGITAL VOLTAGE REGULATOR MANUAL)
• END MOUNTED CONDUIT-BOX LOCATED AT THE REAR OF FRAME. IT PROVIDES AMPLE SPACE TO FTT ATTACHMENTS AND ELEMENTS, AND4 BARS MAY BE CONNECTED EASILY TO LOAD.
• H CLASS INSULATION SYSTEM.
• BEARING IS DOUBLE SHIELDED AND PRE-LUBRICATED FOR LONG LIFE.
• SAE STANDARD ADAPTION.
• EXCITER, PMG AND RECTIFIER ASSEMBLY LOCATED OUTBOARD OF BEARING FOR EASY OF INSPECTION AND MAINTENANCE.

• ACCORDING TO CUSTOMERS' REQUIREMENTS ,WE CAN OFFER DIFFERENT KINDS OF OUTPUT VOLTAGE. ALSO WE CAN OFFER SPECIAL DESIGNS.

5. RESISTANTTO ELECTROMAGNETISM

• GENERATOR EQUIPPED WITH DIGITAL VOLTAGE REGULATOR ACCORDS WITH MIL-STD-461C.

6. BEARING

• SHIELDED HEAVY-DUTY BEARING RESISTS CONTAMINA AND GIVES B-10 TO 20000 HOURS NORMALLY.

7. RUNNING IN PARALLELING

• MX SERIES GENERATORS COULD RUN IN PARALLELING, AND EACH ROTOR BE ASSEMBLED WITH FULL DAMPING WINDING TO PROVIDE STABLE RUNNING.
• IN PARALLELING RUNNING, THE ACTIVE LOADING IS DISTRIBUTED BY ENGINE GOVERNOR, AND THE REACTIVE LOADING IS DISTRIBUTED BY GENERATOR VOLTAGE REGULATOR.
• GENERATORS WITH DIGITAL VOLTAGE REGULATOR COULD ONLY ASSEMBLE CT (5VA) TO SUPPLY DROOP SIGNAL, BECAUSEOFTHE DIGITAL VOLTAGE REGULATORINCLUDING PARALLELING RUNNING FUNCTION.
