A TYPICAL DIESEL GENERATOR SET IS MAINLY DIVIDED INTO FOUR PARTS: DIESEL ENGINE, GENERATOR, CONTROL SYSTEM, AND ACCESSORIES.1. DIESEL ENGINETHE POWER OUTPUT OF THE DIESEL ENGINE IS A PART OF THE ENTIRE UNIT, ACCOUNTING FOR 70% OF THE COST OF THE DIESEL GENERATOR SET, AND SOME BAD MANUFACTURERS LIKE FAKE CONNECTIONS.1.1 FAKE ORGANISMDIESEL ENGINES ARE ALMOST ALL WELL-KNOWN UNIVERSAL MANUFACTURERS IN THE CURRENT MARKET, WITH SOME MANUFACTURERS USING COUNTERFEIT ENGINES OF THE SAME SHAPE, NAMEPLATES, PLAYING WITH REAL, FALSE INFORMATION, AND OTHER PRINTING FACTORY DECKS TO GREATLY REDUCE COSTS. DISTINGUISHING DECK MACHINERY FROM NON PROFESSIONALS IS VERY DIFFICULT.1.2 REFURBISHING OLD MACHINESALL BRANDS REFURBISH OLD MACHINES, WHICH MAY BE DIFFICULT TO DISTINGUISH EVEN FOR NON PROFESSIONALS. BUT THERE ARE SOME DEFECTS IN THE REFURBISHED MACHINE, SUCH AS PAINT, ESPECIALLY BLIND PAINT, WHICH MAKES IT DIFFICULT TO ACHIEVE THE SAME LEVEL AS THE ORIGINAL FACTORY.1.3 CONFUSING THE PUBLIC WITH SIMILAR NAMESTHESE MANUFACTURERS ARE OPPORTUNISTIC AND DO NOT DARE TO MAKE SOME DECK MODIFICATIONS. THEY HAVE DIESEL ENGINE FACTORIES WITH SIMILAR NAMES, WHICH CONFUSE THE PUBLIC WITH DIESEL ENGINES. FOR EXAMPLE, SOME MANUFACTURERS USE PINYIN OR HOMOPHONES WITH DIFFERENT MEANINGS AND USE THE SAME WORDS TO REGISTER THEIR BRANDS, SUCH AS XX CUMMINS GENERATOR COMPANY KILOMETER GENERATOR, ETC., BUT IN REALITY, THERE IS NO CONNECTION WITH CUMMINS ENGINES. THE COMPANY ONLY REGISTERS THE NAME XX GENERATOR, WHICH HAS NO RELATION TO THE "CUMMINS" TRADEMARK, AND PRODUCES VARIOUS CONFIGURATIONS OF FAMOUS DIESEL ENGINE MANUFACTURERS WHO WILL REPURCHASE MOUMOU CUMMINS GENERATORS.1.4 LITTLE HORSE CARCONFUSE THE RELATIONSHIP BETWEEN KVA AND KILOWATTS. SELL KVA KILOWATTS, EXAGGERATE POWER, AND SELL IT TO CUSTOMERS. IN FACT, KVA IS COMMONLY USED ABROAD, AND KILOWATTS ARE THE EFFECTIVE POWER COMMONLY USED IN CHINA. THE RELATIONSHIP BETWEEN THEM IS 1 KILOWATT=1.25 KVA. IMPORTING UNITS GENERALLY USE KVA POWER UNITS, WHILE DOMESTIC POWER EQUIPMENT IS GENERALLY CONVERTED FROM KILOWATTS, SO WHEN ACCOUNTING, KVA SHOULD BE CONVERTED FROM 20% KILOWATTS. DON'T TALK ABOUT COMMON RELATIONSHIPS (RATED) POWER AND RESERVE POWER, SAY THERE IS ONLY ONE "POWER", SELL BACKUP POWER AS A PUBLIC POWER TO CUSTOMERS. IN FACT, THE BACKUP POWER SOURCE=1.1 X IS THE COMMONLY USED (RATED) POWER. IN ADDITION, THE BACKUP POWER SUPPLY CAN ONLY BE USED FOR CONTINUOUS OPERATION FOR 1 HOUR AND 12 HOURS.2. GENERATOR COMPONENTSTHE FUNCTION OF A GENERATOR IS TO CONVERT THE POWER OF A DIESEL ENGINE INTO ELECTRICAL ENERGY, WHICH IS DIRECTLY RELATED TO THE STABILITY OF QUALITY AND OUTPUT POWER.2.1 STATOR COILSTHE INITIAL STATOR COILS WERE USED FOR THE ENTIRE COPPER WIRE, BUT WITH THE ADVANCEMENT OF TECHNOLOGY, COPPER-CLAD ALUMINUM CORE WIRES HAVE BEEN DEVELOPED. UNLIKE COPPER PLATED ALUMINUM WIRE AND COPPER-CLAD ALUMINUM CORE WIRE, WHICH ARE USED TO FORM SPECIAL MOLDS WITH COPPER ALUMINUM COATING AND MUCH THICKER COPPER PLATING LAYER. THE PERFORMANCE OF COPPER COATED ALUMINUM CORE WIRES FOR GENERATOR STATOR COILS IS NOT SIGNIFICANTLY DIFFERENT, ONLY WITH A SHORTER SERVICE LIFE THAN THE ENTIRE COPPER STATOR COIL.2.2 INCENTIVE MODETHE INCENTIVE MODE IS DIVIDED INTO STAGE COMPOSITE EXCITATION BRUSHLESS SELF EXCITATION TYPE. THE ADVANTAGES OF STABLE AND EASY TO MAINTAIN BRUSHLESS SELF-EXCITED EXCITATION HAVE BECOME MAINSTREAM, BUT THERE ARE STILL SOME MANUFACTURERS WHO, DUE TO COST CONSIDERATIONS, CONFIGURE COMPOSITE EXCITATION GENERATORS FOR UNITS BELOW 300 KW.3. CONTROL SYSTEMORDINARY STANDARD UNITS REQUIRE MANUAL SWITCHING FROM POWER-OFF TO DIESEL GENERATOR SET TO START PROPAGATION, USUALLY TAKING 10 TO 30 MINUTES.THE AUTOMATIC CONTROL OF DIESEL GENERATOR SETS IS DIVIDED INTO SEMI-AUTOMATIC AND FULLY AUTOMATIC UNMANNED TYPES. WHEN THE SEMI-AUTOMATIC GENERATOR SET EXPERIENCES A POWER FAILURE DURING AUTOMATIC STARTUP, IT AUTOMATICALLY STOPS AND THE SAVE TIME BEGINS TO SHUT DOWN, BUT MANUAL SWITCHING IS STILL REQUIRED. AUTOMATIC UNMANNED OPERATION AND ATS DUAL POWER SWITCH CONTROL PANEL, AUTOMATIC DETECTION, DIRECT SIGNAL, AUTOMATIC SWITCHING, GENERATOR AUTOMATIC START AND STOP CONTROL, ACHIEVING FULLY AUTOMATIC UNMANNED OPERATION, WITH ADJUSTABLE SWITCH TIME OF 3-7 SECONDS. HOSPITALS, MILITARY UNITS, FIRE STATIONS, AND OTHER ELECTRIC FIELDS SHOULD BE EQUIPPED WITH AUTOMATIC CONTROL PANELS.
