Power selection (Precise matching for high-end scenarios)

1. core selecting basis

2.Power recommendation for typical scenarios

Usage Method (Exclusive operation for imported units)

1.Pre-startup inspection (with a focus on imported components)

2. Startup operation (power distribution process)

(1) 20-200KW (starting with imported engine)

1.ECU self-check: Turn on the controller power and wait for the imported engine ECU to self-check (about 30 seconds). Confirm that there are no fault codes (such as the Cummins "STOP" light not on).

2. Preheating start: Press the "Preheating" button (preheat for 60 seconds in a low-temperature environment, with the inlet preheating plug working), then press the "Start" button. After the engine starts, observe the rotational speed (1500r/min±50r/min) and oil pressure (≥0.3MPa).

3. Loading operation: After the parameters stabilize (about 5 minutes), close the generator output switch and gradually load (the initial load should be ≤50%, and after running for 10 minutes, increase to full load to avoid impacting the inlet generator).

(2) 800-2000KW (High voltage/heavy-duty imported units)

1. High-voltage preparation: Open the "grounding switch" of the imported high-voltage switch cabinet → Close the "disconnector" → Use an imported voltage detector (such as ABB) to confirm that there is no electricity.

2. Startup process: Hydraulic start → Engine speed rises to 1500r/min→ Check the pressure of the imported turbocharger (≥0.2MPa) → Close the high-voltage circuit breaker → Load in stages of "20%→50%→80%→100%".

3.ECU Monitoring: The controller reads the engine ECU data (water temperature, oil temperature, fuel injection pressure) in real time. When the threshold is exceeded, the load is automatically reduced to prevent damage to imported components.

3. Operation Monitoring and Shutdown (Protection of Imported Components)

• Key monitoring points: For 20-200KW, pay attention to the ECU parameters of imported engines (no abnormal codes); for 800-2000KW, focus on high-voltage parameters (voltage 6kV±5%) and the temperature of imported turbochargers (≤600℃).

• Shutdown process:

① 20-200KW: Unload → turn off the output switch → Run no-load for 5 minutes → Shut down → turn off the power of the ECU.

② 800-2000KW: Graded unloading → Disconnect the high-voltage circuit breaker → Open the "disconnector" → close the "grounding switch" → Run no-load for 10 minutes → shut down → Record the ECU operation data (for after-sales analysis).

Safety and Protection (Compliance Specifications for Imported Units)

1. Safe installation (in line with international standards)

• Site selection and layout:

① The installation area should be at least 15 meters away from open flames (the exhaust temperature of imported engines is high, so avoid ignition). For high-pressure models, the safety distance should be at least 3 meters (in compliance with IEC 61936 high-pressure standards).

② The ground load-bearing capacity should be no less than 1.5 times the weight of the unit (for large models, it should be no less than 32000kg×1.5=48000kg/㎡). The foundation should be made of reinforced concrete (with a thickness of no less than 500mm), and equipped with imported shock-absorbing pads (such as Kordon).

③ Overseas projects must comply with local building codes (such as NFPA 110 in the United States and EN 50130-7 in Europe), and Kecheng provides local installation drawing certification.

• Electrical safety:

① The grounding resistance of the imported high-voltage generator is ≤10Ω (conforming to IEC 60364), and that of the low-voltage model is ≤4Ω. The grounding electrode uses imported galvanized flat steel (such as British standard BS EN 10025).

② Imported insulating gloves for high-voltage wiring (with a withstand voltage of 10kV, such as Sperian), and two people should cooperate during operation (one person operating and one person supervising).

③ Imported electrical components (such as circuit breakers and contactors) must be wired in accordance with the original factory specifications. Unauthorized modification is strictly prohibited (to avoid losing the original factory warranty).

• Fire protection configuration:

① The installation area is equipped with imported dry powder fire extinguishers (such as Ansul, ABC type 8kg), and high-pressure models are additionally equipped with CO₂ fire extinguishers (to prevent electric shock).

② The fuel tank is independently set up (at least 10 meters away from the unit), using imported explosion-proof pipe fittings (such as Parker), and complies with the NFPA 30 fuel storage standard.

③ Overseas projects must pass local fire protection acceptance (such as FM certification in the United States and CE fire protection certification in Europe).

2. Operational safety (Exclusive for imported components)

• Personnel requirements:

①Operators must undergo dual training from "imported brands + Kecheng" (such as training authorized by Cummins), and after passing the assessment, they can work with the "Imported Unit Operation Certificate".

② Be familiar with the meaning of ECU fault codes for imported engines (for example, Cummins' "code 128" indicates low oil pressure), and be able to quickly identify basic faults.

③ When operating, wear imported protective equipment (insulating shoes, high-temperature resistant gloves, such as Dupont), and avoid contact with high-temperature components (the temperature of imported turbochargers ≥600℃).

• Operating contraindications:

① Do not use non-imported specified engine oil/filter elements (for example, Cummins requires CJ-4 grade engine oil), otherwise the original factory warranty will be lost.

② It is strictly prohibited to disconnect the imported high-voltage circuit breaker under load (to avoid arc burns, it needs to be unloaded first).

③ Do not force the operation when the ECU alarms (for example, when the "high water temperature" alarm is triggered, the machine should be stopped immediately to prevent the imported engine from pulling the cylinder).

• Emergency response:

① Imported engine failure: Stop immediately → Read the ECU fault code → Contact Kecheng after-sales service (provide the fault code for remote diagnosis by the original factory);

② High-voltage leakage: Disconnect the upper-level power supply → Wear imported insulating equipment → Isolate the fault point with imported insulating rods → Check the wiring.

③ Fire accident: Use imported fire extinguishers to put out the fire → Call the local fire department → Contact the after-sales service of the imported brand to assess the damage to the components.

3. Maintain safety (Specifications for Imported components)

• Preparations before maintenance:

① Disconnect the power supply of the unit, close the fuel valve, hang the warning sign "Under maintenance, do not start", and for high-voltage models, ground discharge is required.

② Prepare imported special tools (such as Cummins special wrenches, Volvo diagnostic instruments), and the spare parts must be genuine products from the original factory (Kecheng provides the import spare parts channel).

③ The maintenance manual should refer to the specifications of the imported brand (such as the maintenance manual of MAN D28), and simplifying the process is strictly prohibited.

• Maintenance operations:

① Oil/filter replacement: Replace the oil with an imported oil pump (such as Black & Decker) in accordance with the required cycle of the imported engine (e.g., 1000 hours for Cummins), and hand over the old oil to a qualified institution for disposal.

② Maintenance of imported generators: Test the insulation resistance with imported insulating oil (≥100MΩ) every six months, and clean the imported bearings (add imported grease, such as Shell Gadus).

③ High-voltage system maintenance: Every year, relay protection (such as ABB protection devices) is calibrated by certified engineers of imported brands and short-circuit withstand capability is tested.
