Product advantages (Fully automatic core competitiveness)

Technical parameters (Full power range: 20-1000KW)

Technical features (Fully automatic exclusive design)

1. Intelligent fully automatic control system (KCPLC series)

• Core functions:

① Automatic start-stop control: When the mains power is interrupted (the detection duration can be set from 1 to 10 seconds), it will automatically start. After the voltage stabilizes, the ATS will switch to power supply for the unit. When the mains power is restored (detection duration: 30-60 seconds), it will automatically unload and shut down, and the ATS will switch back to the mains power.

② Automatic parameter monitoring: Real-time collection of over 15 parameters such as voltage, current, frequency, water temperature, oil pressure, and fuel consumption. Automatic alarm when the threshold is exceeded (for example, shutdown when the high water temperature is ≥95℃).

③ Unattended optimization: Supports "regular self-start test" (automatically starts and runs for 10 minutes every week/month to check the status of the unit), and automatic float charging of the battery (starts the charger when the voltage is ≤12.0V).

④ Multi-unit linkage (medium and large) : The 500-1000KW models support 8 units in parallel, with automatic load distribution (deviation ≤5%). When a single unit fails, other units will automatically replenish the load, ensuring no power supply interruption.

2. Intelligent ATS switching technology

• Basic Model (20-200KW) : Equipped with electromagnetic ATS, the switching time is ≤15 seconds, and it supports the "city power priority" mode, making it suitable for civilian emergency scenarios.

• Smart Model (200-500KW) : Upgraded to electronic ATS with shock-free switching function (voltage fluctuation during switching ≤5%), to prevent damage to commercial equipment (such as cold chain compressors) caused by inrush current;

• Grid-connected model (500-1000KW) : Standard grid-connected ATS, in compliance with GB/T 19939 grid connection standard, can be linked with factory grid/data center high-voltage distribution, and there is no grid disturbance during switching.

3. Remote operation and maintenance as well as diagnosis technology

• Networking method: Models ranging from 20 to 500KW support 4G/WiFi networking, while models from 500 to 1000KW can be connected via satellite (in remote areas with no signal).

• Operation and maintenance functions: Realized through the "Kecheng Electric Power" APP/PC terminal: ① Remote start and stop (hierarchical permission management); ② Real-time viewing of operation data (power generation, fuel consumption, fault codes); ③ Historical data query (1-year storage, export to Excel report); ④ Fault push (SMS + APP notification, including handling suggestions);

• Diagnostic capability: Medium and large-sized models are equipped with a "remote diagnosis" function. Kecheng engineers can remotely read the controller logs to troubleshoot faults (such as fuel injector faults, abnormal excitation), and 80% of the faults do not require on-site repair.

4. Full-scenario automatic protection mechanism

• Basic protection: All models are standardly equipped with "overload (shutdown for 30 seconds under 120% rated load), high water temperature (shutdown for ≥95℃), low oil pressure (shutdown for ≤0.2MPa), undervoltage/overvoltage (shutdown for ±15% rated voltage)" protection.

• Advanced Protection (Medium/Large) : New protection features include "Abnormal frequency (shutdown at 45-55Hz), leakage (tripping when leakage current ≥30mA), and excitation fault (automatic switching to backup excitation)".

• High-voltage protection (medium and large 6kV models) : New protections such as "high-voltage insulation drop (≤50MΩ alarm), short circuit (instantaneous trip), and ground fault (≤10Ω alarm)" have been added, meeting the safety standards for high-voltage distribution.

5. Environmental adaptability and energy-saving optimization

• Low-temperature adaptive: For models below -20℃, an "automatic preheating system" (engine oil preheating + coolant preheating) can be selected. When the ambient temperature is ≤-5℃, the preheating system will automatically start to ensure a start-up success rate of ≥99%.

• Energy-saving control: Medium and large-sized models support "automatic peak-valley power dispatch". After setting the peak and valley periods, the machine will automatically shut down (powered by mains electricity) during off-peak hours (such as 22:00-6:00) and be on standby during peak hours (such as 8:00-22:00), saving 30% to 40% of fuel annually.• Automatic heat dissipation control: The water-cooled model is equipped with an automatic temperature-controlled fan (starts when the water temperature is ≥80℃ and stops when it is ≤70℃), while the air-cooled model automatically adjusts the fan speed to reduce unnecessary energy consumption.

Power Selection (Fully Automatic Scene Precise Matching)

1.Core selecting basis

2.Power recommendation for typical scenarios)

Usage method (Fully automatic and easy operation)

1.Preliminary setup (First use, completed within 1 hour)

2.Automatically run the process (without manual intervention)

1. Standby mode: After the unit is powered on, it enters standby mode. The controller monitors the mains power (voltage/frequency) in real time, and the battery automatically floats to charge.

2. Mains power interruption: When the mains power is abnormal (such as power failure, voltage ≤320V), the controller triggers the start command → automatically preheats (in a low-temperature environment) → starts the engine → After the voltage stabilizes (about 30 seconds) → ATS switches to power supply for the unit.

3. Mains power restoration: Mains power returns to normal (continuous monitoring for 30-60 seconds) → The controller triggers the unloading command → The unit runs no-load for 3-5 minutes (cooling) → Automatic shutdown → ATS switches back to mains power.

4. Fault Handling: In case of faults during operation (such as high water temperature), the controller automatically shuts down → triggers an alarm (APP + SMS) → displays a fault code (for easy troubleshooting).

3. Manual intervention (Emergency/debugging scenarios)

• Emergency shutdown: In case of emergency situations such as "severe oil leakage" or "short circuit", press the "Emergency Shutdown" button on the controller (or remote emergency shutdown via the APP), and the unit will immediately cut off the oil supply and shut down.

• Manual start: During debugging, enter the "manual" mode of the controller, press the "Start" button, and the process is the same as automatic start. Loading requires manually closing the output switch.

• Parameter Viewing: Through the controller display screen or APP, you can view the operating parameters (power generation, fuel consumption, cumulative operating time) in real time, and export the data for archiving every month.

4. Operation monitoring (mainly remote, regular inspection)

• Remote monitoring: Check the unit status (standby/operation/fault) daily through the APP, view historical data (fuel consumption, fault records) weekly, and handle any alarms promptly.

• Regular inspection: Monthly on-site inspection: ① Fuel tank oil level (≥1/3); ② Cooling liquid level (water-cooled models); ③ Controller parameters (no abnormalities); ④ ATS wiring (no looseness);

• Annual test: Manually trigger the "Self-Start Test" (selected from the controller Settings interface) every year, run it for 1 hour, and check whether the switching function and protection function are normal.

Safety and Protection (Specialized Specifications for Fully Automatic)

1. Installation safety (Core of the fully automatic system)

• Electrical safety:

① The wiring between the controller and the ATS should be operated by professionals to ensure that the mains power/unit lines are isolated (to avoid short circuits), and the grounding resistance should be ≤4Ω (low voltage) /≤10Ω (high voltage).

② The remote module (4G/satellite) is installed in a rain-proof position, with the antenna facing unobstructed (to ensure signal), and the cable uses shielded wire (to prevent interference).

③ For high-voltage models (6kV), a separate high-voltage distribution room should be built in compliance with the GB 50060 standard, and high-voltage warning signs should be set up.

• Mechanical safety:

① The load-bearing capacity of the installation foundation for the unit should be no less than 1.2 times the weight of the unit (for example, for a 3500kg unit, it should be no less than 4200kg/㎡), to prevent the ATS wiring from loosening due to vibration.

② Protective covers should be installed on rotating parts (fans, couplings), and it is strictly prohibited to disassemble them during operation.

③ The fuel tank should be independently set up (at least 10 meters away from the unit), equipped with a liquid level alarm (to prevent oil overflow), and must not be close to open flames.

• Fire protection configuration:

① The installation area is equipped with 2 4kg ABC dry powder fire extinguishers (≤5 meters away from the unit), and for high-pressure models, an additional CO₂ fire extinguisher is provided.

② Develop a fire protection plan for automatic shutdown (such as remote oil cut-off via APP in case of fire), and conduct a drill once every quarter.

2. Operational safety (combination of automatic and manual)

• Personnel requirements:

① Operators must be trained by Kecheng, familiar with controller parameter Settings and emergency shutdown operations. Unlicensed personnel are prohibited from modifying the automatic operation parameters.

②When operating remotely, it is necessary to confirm that there are no personnel on site (such as maintenance) to avoid injury caused by misoperation.

• Operating contraindications:

① It is strictly prohibited to disconnect the power supply of the controller during automatic operation (which may prevent automatic startup).

② Do not modify the protection threshold (such as increasing the water temperature protection to 100℃) to avoid damage to the unit.

③ Remote operation is prohibited during thunderstorms. The power supply of the controller must be disconnected (to prevent lightning strikes).

• Emergency response:

① Automatic start failure: Check the battery voltage (insufficient charging), fuel level (replenishment), and mains power test line (no looseness).

② ATS switching fault: Manually switch to mains power, check the ATS wiring (no looseness) and controller synchronization parameters (recalibrate);

③ Remote disconnection: Inspect the network module on-site (restart), switch to satellite networking in remote scenarios, and activate manual mode when recovery is not possible.

3. Maintain safety (Focus on fully automatic components)

• Preparations before maintenance:

① Disconnect the main power supply of the unit, close the fuel valve, and hang a warning sign that reads "Under maintenance, do not start".

② When the remote module is powered off (to prevent false startup), the controller switches to the "Maintenance" mode (locking the automatic function).

• Core component maintenance:

① Controller: Clean the dust (with compressed air at 0.2MPa) every quarter, calibrate the parameters (such as the mains detection threshold), and update the APP to the latest version.

② ATS: Check the contacts every six months (for no erosion, use fine sandpaper to polish for erosion), and test the switching function (manual and automatic three times each).

③ Remote module: Check the antenna (no looseness), network connection (signal strength ≥-80 DBM) every quarter, and test the communication of the satellite module (send test instructions).

• Professional maintenance

① Engine and generator maintenance follows the regular procedures. After maintenance, the automatic start function needs to be tested (to ensure there is no impact).

② For high-voltage models (6kV), every year, Kecheng High-voltage certified engineers will visit the site to test insulation resistance and relay protection parameters to ensure high-voltage safety.
