XICHI
6kV / 10kV
AC motor
185kW ~ 10000kW
Wide range.
1. Input current harmonics
Multi-pulse rectification using transformer phase shift technology, 30 pulses for 6kv systems and 48 pulses for 10kv systems.
Meets IEEE519-2014 standard.
Input filterless.
2. Input power factor
The input transformer phase shift technology combined with cascade modules provide the reactive
power required by the motor with an input power factor of up to 0.96. After the motor has passed
through the high voltage inverter, no reactive power compensation equipment is required.
3. Output voltage waveform
Module-cascaded technology, H-bridge inverter, module output superimposed to form multilevel, output perfect sine wave to ensure the motor work in better condition. It is adaptable to new and old motor.
4. Overall efficiency
Efficiency up to 97%, better electromagnetic design for phase shifting transformers to reduce losses, and IGBT uses international first-tier brand.
5. Grid adaptability
Output voltage fluctuation range -15%-+15%, frequency fluctuation -10%-+10%. Within the fluctuation range it ensures the output rated voltage by output injection harmonic control. It can work with the minimum voltage -45%. When the grid momentarily loses power, the high voltage frequency converter will enter the momentary power loss non-stop function to maintain the motor working, and if the grid is recovered before the system energy storage is depleted, the system will continue to work.
6. Lightning protection
The mains input, output, control power input and communication signals are protected against lightning.
7. Modular design
The control system, electrical system, power module, fan system and detecting unit adopt modular design, being highly reliable, easy to maintain and easy to operation.
8. All-in-one design
10KV 1-2MW, one design for the structure size in the power section, 10KV 1-2.25MW, 10KV 200KW-1 MW and 6KV 185KW-0.8MW. Small in size and space saving.
9. Low voltage soft-start function
The phase shifting transformer is switched to the grid on the high voltage side after the transformer has output a normal voltage by means of a low voltage soft start. The soft start ensures that the phase shifting transformer is switched to the grid without inrush current.
10. Control power
The power supply of the control system adopts a modular design and a dual redundant power supply, with one from low voltage and one from high voltage. The core memory chip inside the control system is powered by a super capacitor to ensure the operation of data storage when the system is powered down.
11. Multiple motor control options
Depending on the motor applications, VF control, vector control and direct torque control (DTC) are available to suit various motor loads.
12. Fault protection
Motor overcurrent protection, output overload protection, input overvoltage and overcurrent protection, phase shifting transformer overheat protection, communication fault protection, power unit fault, output short circuit protection, IGBT overcurrent protection, operation gate open protection, etc.
13. Rich user interfaces
It has interfaces for RS485, analogue input, analogue output, digital input, digital output, encoder input, power control,
power output, high voltage circuit breaker control and detection, emergency stop, etc. to meet a wide range of applications.
14. Power module design
Independent duct design, adaptable to various industrial applications. Interference-free fibre optic control signals. Module control adopts DSP digital control.
15. Master control system
DSP+FPGA architecture is used to complete motor algorithms, logic control, fault handling, SVPWM regulation, communication, signal processing and other functions to perform motor control accurately, quickly and reliably.
16. Interference-free switching technology
High-voltage frequency converter can achieve synchronous motor or asynchronous motor soft start, with motor starting from 0HZ and gradually running to the grid frequency of 50HZ. Then the motor switches from the frequency conversion state to the industrial frequency grid, with the switching process smooth and there is no impact current on the motor so as to ensure the safe operation of the motor.
17. Easy maintenance
With a modular design, each part is a separate module, and it only needs to handle the corresponding module during maintenance, allowing the ventilation dust screen to be replaced or cleaned under normal operation.
18. Highly adaptable to the environment
Protection class IP30; pollution class II. It meets start-up at -15℃ and can work at a maximum temperature of 55℃;
Storage and transport temperature -40℃to +70℃;
The complete machine passes the Class III road transport test;
Power module, control system, detection unit, electrical system and other modules pass the 0.6m drop test and vibration test.
