3000kVA dry-type load bank 380V 2400KW intelligent testing system
| Technical Parameters | |
| Rated voltage/frequency | AC three-phase four-wire, line voltage 380V/50Hz, |
| Load Power (AC380V/50Hz) |
Apparent power: 3000kVA; Resistive power: 2400kW; Inductive power: 1800kvar. |
| Load Step AC380V/50Hz |
Resistive load: divided into 20 levels: They are: 1, 2, 2, 5, 10, 10, 20, 50, 100, 200, 200, 200, 200, 200, 200, 200, 200, 200, 200kW. Sensory load: divided into 17 levels: They are: 1, 2, 2, 5, 10, 10, 20, 50, 100, 200, 200, 200, 200, 200, 200, 200kVar. Explanation: When the voltage is lower than the rated voltage, the gear power of the load cabinet decreases according to Ohm's law. |
| Power Factor | 0.8 (lag, resistive: 2400kW; Sensory: 1800kvar -1 (2400kW). |
| Compatible Voltage | Compatible with AC400V/50Hz, the load power varies according to Ohm's law. |
| Resistance three-phase balance | ±3% |
| Load Tolerance (step) | ±5%; |
| Load Tolerance (overall) | ±3% |
| Display Precision | 0.5 class |
| Control Power Supply | External mains AC three-phase five wire 380-400V/50Hz and load internal power supply, dual power supply uninterruptible conversion. |
| Wire Connection | Control power input - wiring harness. |
| Load wiring method | Load power input - copper bar (star connection). |
| Communication Interface | RS485,RS232 |
| Load bank protection function | Short circuit protection/overvoltage protection/overcurrent protection/over temperature alarm protection/fan fault protection/phase sequence protection |
| Scalability | The communication interface and layout of the load cabinet system are flexible, and the system has scalability, making it convenient for future station and power increases. |
| Resistance installation method | The power resistor module is fixed using a high-strength insulation composite architecture. |
| Insulation Class | F Class |
| Maximum protection level | IP55 (control part) |
| Cooling method | There is a waterproof edge around the top air outlet of the chassis, which can guide rainwater to flow down from a safe location, prevent water accumulation at the top, and facilitate the storage and use of the chassis in continuous rainy weather. It also has a rainproof elbow air outlet duct. |
| Working Mode | Continuous Working |
| Cooling | Adopting axial flow fan, forced air cooling, side inlet, upper outlet, air outlet with air duct, and air outlet on both sides. The ventilation openings on both sides and the top air outlet are equipped with louvers and stainless steel protective nets to prevent small animals and other foreign objects from entering. The inlet and outlet of the equipment cabinet have protective doors that are waterproof when closed. The equipment has rainproof settings, which can ensure that the system insulation is not affected even when working in rainy weather. |
| Chassis structure | 1. The load bank adopts a standard container design and is equipped with a ladder that can reach the top. There are load-bearing lifting holes that meet the lifting and transportation conditions. 2. The equipment is equipped with an operation room, which is equipped with air conditioning and an office desk. The fixed installation of the office desk is suitable for transportation and lifting with containers. |
| Transportation | The top of the chassis has load-bearing lifting holes, which meet the requirements for long-distance transportation by car. |
| Casing Color | RAL7035+ Black |
| Dimension | About 8000mm×2438mm×2591mm |
| Weight | About 17000KGS |
| Operating Environment Parameter | |
| Workplace | Outdoor |
| Work Temperature | -20ºC~+50ºC |
| Relative Humidity | ≤95% |
| Altitude | ≤2500M |
| Atmospheric Pressure | 86~106kPa |
1. Control mode selection: The load can be controlled locally, remotely, or intelligently.
2. Local control: Manual loading/unloading control of the load box and viewing of test data can be achieved through switches and instruments on the local control panel.
3. Remote control: The system is equipped with a remote control handheld box, which allows for remote loading/unloading control through buttons on the handheld box.
4. Intelligent control: Control the load through data management software on the computer, achieve automatic loading, display, record and manage test data, generate various curves and charts, and support printing.
5. Control mode interlock: The system is equipped with a control mode selection switch. After selecting any control mode, operations performed through other modes are invalid, avoiding conflicts caused by multiple operations.
6. One click loading and unloading: Regardless of whether manual switch or software control is used, the power value can be set first, and then the main loading switch can be activated. Only then will the load be loaded according to the preset value, thus avoiding load fluctuations during power adjustment.
7. Local instrument display data: Three phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency and other parameters can be displayed through local measuring instruments.
8. Auxiliary function: The load cabinet control panel is designed with lighting switches and reserved single-phase 220V/50Hz power sockets for computers or other temporary power consumption.
9. The system can switch from steady-state testing to transient testing operation mode without the need for uninstallation; Transient testing requires the freedom to set any time interval, with a minimum time interval of 3-5 seconds, and the ability to generate test data.
10. The system can maintain the original load in case of communication interruption or computer crash, and automatically detect and put the original load into operation after reconnecting the device, without causing sudden load unloading/addition during the process.
11. The system should set the dip gear and manually adjust it when there is a slight deviation in power and power factor.
