Product Advantages (Core Competitiveness of Kecheng Electric Power)

Technical parameters (Mainstream models of Kecheng Electric Power)

Technical features (Patented technology of Kecheng Electric Power)

1. Intelligent emergency control system

• Equipped with the KCPLC-01 controller independently developed by Kecheng, it supports "automatic/manual/remote" three-mode control and can be linked with the ATS automatic transfer switch to achieve automatic start when power is off and automatic stop when power is restored.

• It can monitor over 20 operating parameters in real time (such as rotational speed, oil pressure, water temperature, voltage, current, etc.), automatically alarm and record in case of faults (storing 100 fault codes), and supports remote monitoring via mobile phone APP (viewing parameters, start-stop control).

2. High-efficiency power system

• It is compatible with Yuchai YC, Weichai WP and Cummins QSK series engines. It adopts high-pressure common rail + turbocharging technology, which increases combustion efficiency by 12%. When starting at low temperatures, the fuel is heated through the preheating plug, and it can start normally in an environment of -30℃.

• The generator adopts brushless self-excitation technology, with a voltage establishment time of ≤0.5 seconds and strong resistance to load shock (capable of withstanding a sudden increase of 100% of the rated load).

3. Strengthen protection and noise reduction design

• The outer cover of the unit is made of double-layer cold-rolled steel plate (inner layer of sound-absorbing cotton + outer layer of anti-rust coating), with a noise reduction of up to 25dB, meeting the noise requirements of commercial and civil areas.

• The electrical system has a protection grade of IP24 and can withstand light rain and dust. The fuel tank adopts a leak-proof design and complies with GB 18296-2019 "Safety Performance Requirements and Test Methods for Automotive Fuel Tanks".

4. Redundant design for emergency support

• Dual-battery starting system (serving as backups for each other) to prevent starting failure caused by a single battery being discharged.

• The fuel tank capacity supports full-load operation for 8 to 24 hours and can be connected to a large-capacity fuel tank for long-term emergency power supply.

• The key components (such as oil pumps and water pumps) adopt redundant design. When a single component fails, the backup component will be automatically put into operation.

Usage Method (Kecheng Electric Power Standard Operating Procedure)

1.Pre-startup inspection (Mandatory before emergency startup)

2. Emergency start-up operation (automatic mode, recommended)

1. Switch the controller knob to the "Auto" mode, and the ATS will automatically monitor the grid voltage.

2. When the power grid is cut off, the ATS triggers the start-up signal of the unit, and the unit starts automatically (start-up time ≤15 seconds).

3. After startup, the controller monitors the rotational speed (up to 1500r/min), oil pressure (≥0.3MPa), and water temperature (gradually rising to 70℃). Once the parameters stabilize, the ATS automatically switches the load to supply power to the unit.

3. Manual start operation (emergency backup)

1. Switch the controller to "manual" mode and press the "Preheat" button (preheat for 30-60 seconds in low-temperature environments);

2. Press the "Start" button. After the unit starts, observe the parameters. Once they stabilize, manually close the output switch and then switch the load through ATS.

3. When the load is put into operation, it should be gradually loaded. The initial loading should not exceed 50% of the rated power. After 5 minutes, it can be raised to full load.

4. Shutdown operation (after power grid restoration)

1. After the power grid resumes power supply, the ATS automatically disconnects the load of the unit and switches to power supply from the grid.

2. When the unit enters no-load operation (for 3 to 5 minutes to cool down the engine), the controller automatically shuts down (or manually press the "Stop" button).

3. After the machine stops (for long-term shutdown), close the fuel valve, check for any leakage or component damage in the unit, and record the operating data.

Precautions (safety and maintenance)

1. Safety Protection (Red Line Clause)

1. The installation area of the unit should be far away from open flames, flammable and explosive items, and have good ventilation (the ventilation volume per hour should be ≥ 15 times the volume of the unit).

2. Operators must be professionally trained by Kecheng Electric Power and hold relevant certificates before taking up their posts. It is strictly prohibited to disassemble fuel pipelines and electrical components when the unit is in operation.

When starting up in an emergency, it is necessary to confirm that there is no short circuit at the load end to avoid equipment damage caused by starting the unit under load.

3.Regularly check whether the gas leakage alarm (if any) and fire extinguisher are functioning properly to ensure they can be used in emergency situations.

2.Maintenance Cycle (Recommended by Kecheng Electric Power)

3.Environmental adaptation measures

• High-temperature environment (≥40℃) : Install cooling fans and sunshades, and check the coolant temperature every 2 hours (≤95℃).

• Low-temperature environment (≤-10℃) : Replace low-temperature engine oil and antifreeze (concentration ≥50%), and activate the fuel preheater and engine oil preheater.

• High-altitude environment (≥1000 meters) : The engine needs to be modified for high altitudes (increasing the intake air volume), with power correction factors of 0.95 (1000-2000 meters) and 0.9 (2000-3000 meters).
