WHEN INSTALLING THE GENERATOR, ENSURE SMOOTH COOLING AIR INTAKE TO PREVENT HOT AIR FROM RETURNING TO THE GENERATOR. IF THE VENTILATION HOOD PROVIDED IS A SHUTTER, THE WINDOW SHOULD BE LOWERED TO THE REQUIRED LEVEL OF PROTECTION. SPECIAL ATTENTION SHOULD BE PAID TO THE AIR GAP BETWEEN THE STATOR AND ROTOR OF A MECHANICALLY COUPLED GENERATOR WITH A SINGLE BEARING.THE PARALLELISM AND CONCENTRATION OF COUPLING BETWEEN AC GENERATORS AND DIESEL GENERATORS NEED TO BE LESS THAN 0.05 MILLIMETERS. IT CAN MEET A SLIGHT PRACTICAL USAGE REQUIREMENT OF ABOUT 0.1 MILLIMETERS, WHICH CAN AFFECT THE NORMAL OPERATION OF THE BEARING AND CAUSE DAMAGE, COUPLED WITH A GOOD POSITIONING PIN FIXATION. THE COUPLING CONDITIONS THAT SHOULD BE MEASURED BEFORE INSTALLATION.THERE ARE U, V, W, N AT THE TERMINAL BOX OF THE GENERATOR OUTLET, WHICH DOES NOT MEAN THAT THE ACTUAL PHASE SEQUENCE DEPENDS ON THE DIRECTION OF ROTATION. THE CERTIFICATE IS PRINTED ON UVW TO INDICATE THAT THE ACTUAL PHASE SEQUENCE ROTATES CLOCKWISE, WHILE VUW MEANS THAT THE ACTUAL PHASE SEQUENCE ROTATES COUNTERCLOCKWISE.SLIDING BEARINGS ARE COUPLED TO THE GENERATOR, AND THE HEIGHT OF THE CENTER IS USED TO ADJUST THE CENTER OF YOUR ENGINE, SO THAT THE WEIGHT OF THE DIESEL ENGINE FLYWHEEL DOES NOT TRANSFER TO THE GENERATOR BEARING OR THE GENERATOR BEARING BEARS THE WEIGHT OF THE FLYWHEEL, WHICH IS NOT CONDUCIVE TO THE FORMATION OF AN OIL FILM ON THE SLIDING BEARING AND CAN CAUSE FEVER, EVEN IF THE BEARING BURNS. THIS TYPE OF GENERATOR COUPLING CANNOT TAKE ANY HEAVY MEASURES.IF THE NEUTRAL POINT POWER SUPPLY SYSTEM OF EACH GENERATOR IS INTERCONNECTED, OR IF THE NEUTRAL POINT OF THE GENERATOR IS CONNECTED TO THE NEUTRAL POINT OF THE TRANSFORMER LOAD, THE NEUTRAL LINE CURRENT IN THE NEUTRAL LINE WILL BE THREE TIMES THAT OF THE NEUTRAL LINE. THEREFORE, IT IS NECESSARY TO DETERMINE THE CENTRAL LINE CURRENT GENERATOR UNDER VARIOUS LOAD CONDITIONS. IN ORDER TO AVOID OVERHEATING THE GENERATOR, THE LINE CURRENT MUST NOT EXCEED 50% OF THE RATED CURRENT. THE CENTRAL LINE HAS TOO MUCH POWER AND SHOULD BE INSTALLED WITHIN THE REACTOR LIMIT.ACCORDING TO THE SCHEMATIC AND WIRING DIAGRAM, SELECT APPROPRIATE POWER CABLES AND COPPER, COPPER CONNECTORS AND JOINT CONNECTIONS FOR BUSES, BUSES AND BUS LOCKS, WITH A LOCAL GAP OF NO MORE THAN 0.05 MILLIMETERS AND A DISTANCE BETWEEN WIRES OF LESS THAN 10 MILLIMETERS. NECESSARY GROUNDING WIRES ALSO NEED TO BE INSTALLED.
