Product Description

High voltage frequency converter

The frequency converter takes high-speed DSP as the control core, adopts space voltage vector control technology and power unit series multi-level technology.With high reliability,easy operation and high performance as the design goals,it can meet the needs of users for various types of load speed regulation,energy saving and production process improvement .

System structure

The structure of high voltage inverter is shown in Figure , includes phase shifting transformer, power cells and controller. 6kV series inverter contains 5 cells each phase, 15 cells in total. 10kV series inverter contains 8 cells each phase, 24 cells in total.

structure

The structures of power cell are common, which are shown in Figure , it is the AC - DC - AC single phase inverter circuit, rectifier diodes are for the three phase full-wave, IGBT inverter bridge controlled by sinusoidal PWM technology

Features:

*Comprehensive waveform display and recording

The main control system can monitor the input current, voltage, output voltage and current in real time, display the waveform, and analyze the harmonic of each phase voltage and current, which is helpful for users to master various electrical parameters of the equipment

*Double loop control power supply, stable and reliable.

*High power density: small cell size, modular design; The whole machine is compact in structure and occupies little space.

*DC braking technology: when the motor is rotating (below 10Hz), DC braking current is applied to force the motor from rotating state to stopping state.

*Current limiting technology: when the inverter is running, if the current exceeds the limit value, limit the increase of current by reducing the frequency until the current is less than the limit value, and the inverter returns to the normal operating frequency.

*Overvoltage stall technology: during frequency reduction of the frequency converter, the motor generates electricity. When the bus rises, the frequency converter automatically lengthens the frequency reduction time to prevent the shutdown problem caused by bus overvoltage.

*Multiple control modes: local control, remote control box control and DCS control can be selected; Support MODBUS, PROFIBUS and other communication protocols; Frequency setting can be set on site, communication, etc; Support frequency preset, acceleration and deceleration functions.

*Acceleration and deceleration self-adaptive function: the frequency converter adjusts the acceleration time or limits the operating frequency of the motor according to the current load current of the motor, so as to limit the current and realize the function of no current during acceleration. During frequency reduction of frequency converter, the frequency reduction time is adjusted according to the bus voltage, so as to achieve the function of no overvoltage during frequency reduction.

*Black box function and intelligent analysis:

The equipment has the function of automatically recording the operation status and displaying, and can view the output current, output voltage, set frequency, operation frequency, input current and input voltage values of 200 points (100ms) before and after the protection, which is convenient for daily maintenance and rapid abnormal diagnosis.
