Typical application scenarios

New energy photovoltaic grid connected system:

In a 10kV centralized photovoltaic power station, 5SDF1045H0002 serves as the core power unit of the inverter, converting the DC power output from the photovoltaic array into 10kV AC power through PWM modulation; The module's 4500 V high voltage withstand capability is adapted to the DC side voltage of the inverter (up to 1500 V DC), and the 10 kHz switching frequency achieves low harmonic distortion (THD ≤ 3%) of the grid connected current; Upload module temperature, output current, and other data to the PM825 control system through the TC512V1 bus module. When overcurrent or overheating is detected, the shutdown protection is immediately triggered to ensure grid stability.

Variable frequency drive for metallurgical industry rolling mills:

In the 10kV main drive frequency converter of the hot rolling production line in the steel plant, six 5SDF1045H0002 modules form a three-phase bridge rectifier and inverter circuit to achieve the conversion of AC power from the power grid to the variable frequency power supply required for the rolling mill motor; The high current output of module 1000 A meets the load requirements of the rolling mill motor (power 5000 kW), and the 10 kHz switching frequency enables the motor speed adjustment accuracy to reach ± 1 rpm; The response time of overcurrent protection is ≤ 1 μ s, which can withstand the instantaneous surge current of the rolling mill biting steel and avoid production interruption caused by frequency converter failure.

Rail Transit Traction Converter:

In high-speed rail or subway traction inverters, the 5SDF1045H0002 module is responsible for converting the 25kV AC power of the contact network into DC (rectification stage), and then inverting it into the variable frequency power supply required by the traction motor (inverter stage); The anti vibration capability of the pressure sealed package is suitable for the bumpy environment during train operation, and the low-temperature starting performance at -40 ℃ meets the operational requirements in cold regions; Parallel operation of modules achieves 3000 A current output, and with the cooperation of the TC512V1 bus module's PROFIBUS DP communication, the traction current and module temperature data are transmitted to the train control system to achieve real-time adjustment of traction power.

Charging and discharging control of industrial energy storage system:

In large-scale lithium battery energy storage power plants, the 5SDF1045H0002 module serves as the power core of the bidirectional converter. During charging, it converts AC power from the grid to DC power to charge the battery pack, and during discharging, it converts DC power from the battery to AC power and feeds it back to the grid; 4500 V high-voltage withstand adaptive energy storage system DC side (2000 V DC), bidirectional power control to achieve flexible energy scheduling; The overheat protection and fault diagnosis functions are uploaded to PM825 through TC512V1. When the battery pack is overcharged or the module is abnormal, the charging and discharging circuit is immediately cut off to ensure the safety of the energy storage system.

Selection and usage precautions

（1） Key selection points

Select based on voltage and current levels:

Priority should be given to selecting 5SDF1045H0002 with a rated voltage of 4500 V for medium and high voltage systems (10kV-35kV); Low voltage systems (380V-6kV) can choose ABB low-voltage series modules (such as FS450R12KE3); When a single module with a current of 1000 A cannot meet the demand, parallel expansion (up to 8 units in parallel) is required, which requires a matching current sharing control board.

In scenarios where the switching frequency requirement is greater than 10 kHz (such as precision servo drives), it is necessary to confirm whether the switching loss of the module meets the system's heat dissipation requirements to avoid overheating damage.

Confirm protection and diagnostic requirements:

Key equipment (such as nuclear power converters) must ensure that the module has complete overcurrent, overvoltage, overheating protection functions and fault signal output; For scenarios that require remote monitoring, a driver board that supports PROFIBUS DP communication is required to achieve integration with the AC 800M system.

Adaptation of heat dissipation and drive system:

According to the thermal resistance of the module (0.0025 K/W), the heat dissipation requirement is calculated as follows: the heating power during 1000 A operation is about 1.8 kW, and a water-cooled radiator with a heat dissipation area of ≥ 0.5 m ² (inlet water temperature ≤ 35 ℃) is required; The driver board should choose an ABB compatible model (such as DDB100.1) to avoid module misoperation caused by mismatched drive signals.

（2） Installation and wiring precautions

Installation environment requirements:

Installed in a metal enclosed power cabinet, with a distance of ≥ 30 cm from the control module (such as TC512V1) to avoid high voltage interference; The cabinet should have ventilation or water cooling interfaces, and the ambient temperature should be controlled between -40 ℃ and+40 ℃ (shell temperature); Stay away from corrosive gases and dust environments, and install dehumidification devices (relative humidity ≤ 70%) in humid areas.

Wiring specifications:

Main circuit wiring: Copper bars (cross-sectional area ≥ 120 mm ²) are used for connection, and the surface of the copper bars is tinned to reduce contact resistance; Connect a fast fuse in series between the positive and negative terminals of the module and the busbar (rated current 1200 A, breaking capacity ≥ 50 kA); The wiring torque strictly follows the packaging requirements (crimping bolt torque 25 N · m) to avoid poor contact and heat generation.

Control circuit wiring: The drive signal cable adopts twisted pair shielded wire (shielded layer single end grounding, grounding resistance ≤ 4 Ω), with a distance of ≥ 20 cm from the main circuit cable; the fault signal output line is connected to the DI interface of the TC512V1 bus module to achieve fault information upload.

Wiring of cooling system: The water cooling system needs to be equipped with a flow switch and temperature sensor, and the signal should be connected to the PM825 control system. When the flow rate is less than 10 L/min or the water temperature is greater than 40 ℃, an alarm will be triggered.

（3） Key points for use and maintenance

Parameter configuration optimization:

Set overcurrent protection threshold (recommended 1100 A, with a 10% margin reserved) and overheat protection threshold (125 ℃ alarm, 150 ℃ lockout) through the driver board; Adjust the PWM switch frequency according to the load characteristics (5 kHz for fan load and 10 kHz for rolling mill load), balance switch losses and control accuracy; The parallel module needs to calibrate the current sharing resistor to ensure that the current sharing error is ≤ 5%.

Regular maintenance and inspection:

Check the appearance of the module every month (without bulges or oil leakage), the fastening status of the wiring bolts, and use an infrared thermometer to detect the temperature at the copper bar connection (≤ 60 ℃); View the module junction temperature (normal ≤ 100 ℃) and operating current through Control Builder M software, and compare historical data to determine performance degradation.

Clean the cooling system quarterly (descaling of water-cooled radiators and dust removal of air-cooled filters), test the protection function (simulate overcurrent signals, check if the module is immediately turned off); Annual insulation performance testing (insulation resistance measured with a shake meter ≥ 100 M Ω), replacement of aging drive cables and fuses.

Fault handling and spare parts management:

Firstly, investigate the load short circuit (such as motor winding grounding) for module overcurrent faults, and then check the drive board signal; Overvoltage faults require testing of the bus voltage (whether it exceeds 5000 V) and absorption capacitor performance; The backup module needs to be stored in a dry environment (relative humidity ≤ 60%) and regularly (every 6 months) powered on for testing to ensure that the backup state is effective.
