The technical data as follows: 1. Main performance index (1) Drip-leak-proof structure:(IP22 protection class) (2) Insulation class H (3) Rated voltage 400v (4) Three phase four wires (5) Adjusting rate of stable voltageâ?¤Ã‚±1%(6) Transient state voltage -15%ï½?+20% (7) Wave aberration rate of voltage THDâ?¤3% (8) Telephone harmony wave factor of telephone THFâ?¤2% (9) Telephone effective factor of telephone TIFâ?¤50 2. Environment conditions (1) Altitude: not exceed 1000m. (2) Cooling air temperature:258-313k(-15â??ï½?40â??). (3) Relative air humidity: not exceed 90%3. Features(1) Reliable automatic voltage control exciting system, providing invariable excitation on all occasions. (2) Easy to be connected with power network or other generators. (3) Balance rotor with single or two sealed ball bearings. Convenient installation and easy maintenance, easy access to terminal, rotating rectifier and coupling bolts. (4) Meet all the main landing standards. (5) Wide range of flange adaptor and single bearing coupling disc. 4. Electrical character (1) Excitation system: The standard AVR are EA05A-3, EA04; SX440, SX460 or MAX321 (optional). The main stator provides power for excitation of the exciter field via AVR.High efficiency Semiconductor inside AVR will ensure the output voltage up to the rated max from the lower gradually. Output power of exciterâ??s rotor is input to that of mains through3-phase full wave rectifier. Two ends of the rectifier are connected with permanent magnetic steel. It can make generator starting smoothly in any occasions. All the adjusting rate of stable voltage of the AVRâ?¤Ã‚±1%.SX440 has parallel connection, low frequency protection, exterior voltage adjustment and other function. MAX321 is for the permanent magnetic motors. (2) Voltage regulation: Voltage regulation refers to the change of from no-load with power factorranging from0.8to 1 and 4%â??s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR. (3) Insulation class H: All the components are made up with special materials, also immersed in lacquer by peculiar tech. varnish and colophony materials are developed to strengthen the processing and machinery intensity of windings and revolving parts for protecting the generator work under corrosive environment. (4) Windings and electric features: All the generator stators adopt high magnetic conductibility energy cold rolling silicon steel plate to fold up, double winding, firmly structure, good insulating. Continuous damp windings abate surges. The poles and gears of the windings are carefully chosen and this helps to check the wave distortion of output voltage. (5) Phone interference: THF (defined by BS EN 60034-1) â?¤2%.TIF(defined by NEMA MG1-22)â?¤50. (6) Radio interference: Brushless apparatus and quality AVR ensure little radio interference in noise filter is also available. 5. Mechanical features (1) Frame All industrial standard generators are IP22 (NEMA1).Also IP23 is an option, but rated power will decrease 5%; Marine standard generator is IP 23, air filter is an option, but rated power of the generator also will decrease 5% while it is installed. (2) Axis and key: All of the generator rotors should pass balance test, whose vibration are lower than the minimum of BS6861.P.1, bearing generator has a half-key testing balance. (3) Terminal and terminal box: The three-field generator has leads brought out to the terminals in the terminals box, and the terminals are put on the non drive end. The box is equipped with removable panels. (4) Engine adaptor and coupling: Single-bearing, engine adaptor to SAE#00ã??0ã??1/2ã??1ã??2ã??3ã??4ã??5ï¼?coupling discs to SAE#6.5ã??7.5ã??8ã??10ã??11.5ã??14ã??16ã??18ã??21. Double-bearing, engine adaptor to SAE#00ã??0ã??1/2ã??1ã??2ã??3ã??4ã??56. Option parts (1) Adaptors and drive disks (2) Single phase (3) Remote voltage adjust (4) IP 23 enclosure (5) Space heaters (6) Thermistor (7) Voltage 600V and higher (8) Additional permanent magnet system
