1. Heavy Industry Power Systems
• Application Equipment: Electric arc furnaces and rolling mills in the metallurgical industry; large compressors and reactor motors in the chemical industry; drive systems for cement rotary kilns in the building materials industry.
• Core Value: Provides stable 1MVA power output, enables soft start and speed regulation control of motors, reduces equipment start-up impact, and extends mechanical service life.
2. New Energy Power Generation Supporting
• Application Scenarios: Power conversion units for 100kW-1MW photovoltaic inverters and energy storage systems (ESS); power regulation modules for combiner boxes in small and medium-sized wind farms.
• Core Value: Adapts to the fluctuating power characteristics of new energy generation, realizes efficient power conversion and grid connection, and ensures grid stability.
3. Industrial Power Distribution & Compensation Systems
• Application Scenarios: Power compensation modules in power distribution systems of large factories (e.g., automobile manufacturing, electronic industrial parks); reactive power regulation units for high-voltage motors.
• Core Value: Improves the power factor of the power distribution system, reduces line loss, avoids grid overload, and ensures continuous operation of high-power equipment.
4. Rail Transit Auxiliary Power Supply
• Application Scenarios: Auxiliary power modules for traction converters in subways and light rails; power supply units for high-power air conditioners and lighting systems in high-speed railway stations.
• Core Value: Adapts to the high reliability requirements of rail transit, maintaining stable power supply under frequent start-stop and load fluctuations.

4. Usage Instructions (Operating Specifications & Precautions)

4.1 Installation Requirements

• Installation Environment: The module must be installed in an industrial cabinet with good ventilation and free of corrosive gases/dust. A heat dissipation space of ≥20cm must be reserved in the cabinet (the module generates heat during operation and needs to be matched with forced air cooling or water cooling systems).
• Wiring Specifications: Copper bars (with cross-sectional area ≥120mm²) must be used for input/output connections. Before wiring, confirm that the grid voltage matches the rated voltage of the module; the grounding terminal must be reliably connected (grounding resistance ≤4Ω) to avoid electric shock risks.
• Mechanical Fixing: The module must be fixed on the cabinet tray with bottom bolts. The bolt torque must comply with the manufacturer’s requirements (Reference value: 8-10N·m for M8 bolts) to prevent loose wiring caused by vibration.

4.2 Operating Procedures

1. Pre-Power-On Inspection: Confirm that the wiring is correct (no short circuits or loose connections), check that the module appearance is intact, and ensure the heat dissipation system (fans/water cooling) is normal.
2. No-Load Debugging: First connect the control power supply (usually 24V DC), set the rated parameters (e.g., output voltage, frequency) through the upper computer or local control panel, and confirm that the module has no fault alarms.
3. Loaded Operation: Gradually increase the load to the rated capacity (it is recommended to load in 3 stages: 30%→60%→100%), and monitor the module current, temperature, and voltage parameters in real time to ensure no abnormalities.
4. Shutdown Operation: First cut off the load, then disconnect the module’s main power supply, and finally turn off the control power supply; for long-term shutdown, dust-proof and moisture-proof protection (e.g., covering with a dust cover) must be provided.

4.3 Maintenance & Servicing

• Regular Inspection: Check the heat dissipation system weekly (no dust accumulation on fan blades, no leakage in water cooling pipes), detect the temperature of terminal blocks monthly (≤60℃), and calibrate the protection parameters (overvoltage/overcurrent thresholds) quarterly.
• Troubleshooting: If the module reports an "overheating fault", stop the machine immediately to check the heat dissipation system; if an "overcurrent fault" is reported, check whether the load is short-circuited or overloaded, and restart only after the fault is eliminated.
• Service Life Reminder: The design life of the module’s core components (e.g., IGBT) is approximately 8-10 years (based on 8 hours of rated load operation per day). Beyond the service life, component inspection or replacement is required to avoid sudden faults.

4.4 Safety Warnings

• Do not open the cabinet door when the module is in operation to avoid high-voltage electric shock risks;
• For maintenance, disconnect all power supplies (main power supply + control power supply) and wait for ≥10 minutes (for capacitor discharge) before operation;
• Long-term operation exceeding the module’s rated capacity (1MVA) is prohibited, as it will cause overheating and damage to components.
