Product features

High speed DSP control core adopts SPWM modulation technology;

Using space voltage vector control technology, it has the advantages of small starting current, large output torque, smooth speed regulation, small impact on power grid and easy centralized control;

The built-in PID function can adjust the voltage and frequency of the motor working power supply according to the change of the motor load or the change of external variables (such as pipeline pressure), so as to achieve the desired goal torque demand, obvious energy saving effect, economic and stable operation;

Using power unit series multilevel technology, high reliability and easy operation;

Meet all kinds of load speed regulation requirements of users, improve the production process;

The harmonic index is far less than the harmonic standard of IEEE 519-2014, the input power factor is high, the output waveform quality is good, and it is unnecessary to use the input harmonic filter and power factor compensation

Compensation device and output filter; There are no additional heating, torque ripple, noise, output DV / DT, common mode voltage and other problems caused by harmonics.

Perfect protection mechanism: the power unit includes a variety of protection functions, such as phase loss, over-voltage, over-current, under voltage, communication fault, etc. The machine can still bypass automatically; The whole machine protection includes input over-voltage, input under voltage, output phase loss, software over-current, motor overload, output short circuit, instantaneous power failure and leakage current lock, insulation monitoring, protective grounding, power electronic power device overheating and other protection functions.

Current limiting technology: if the current exceeds the limit value, the increase of current is limited by frequency reduction until the current is less than the limit value, the frequency converter returns to normal operation frequency.

Acceleration and deceleration adaptive function: the product adjusts the acceleration time or limits the motor operation frequency according to the motor current, so as to limit the current and realize no over current during acceleration and deceleration. In the process of frequency reduction, the frequency reduction time is adjusted according to the bus voltage, so as to achieve the function of no overvoltage in the process.

Vibration suppression function: when the motor is under light load or no-load, local instability will occur. At this time, the current amplitude fluctuates greatly, which may cause the system to be damaged by over-current or over-voltage trigger protection and current oscillation suppression function can effectively suppress the current oscillation and ensure the stable and reliable operation of the system.

Over voltage stall Technology: in the process of frequency reduction, the motor is in power generation state, forcing the bus voltage to be raised. This function will automatically lengthen the frequency reduction time to prevent the shutdown problem caused by bus overvoltage.

Applications:

Explosion proof variable frequency speed regulation is a high efficiency and high performance speed regulation mode. By controlling the asynchronous motor (or synchronous machine), it can realize step-less smooth speed regulation and meet the requirements of various production machinery. The use of variable frequency speed regulation in coal mine has become the current trend of mine equipment speed regulation. The main equipment loads of explosion-proof inverter used in underground are: belt conveyor, scraper, winch (monkey car), shearer, all kinds of fans, water supply and drainage pump, emulsion pump, etc.;

The explosion-proof frequency converter is suitable for the speed regulating operation of the motor driven by various mining, transportation, ventilation, drainage and other equipment under the condition of coal dust and gas explosion gas content not exceeding the specified safety content in the coal mine, realizing the functions of motor heavy load soft start and soft stop, step-less speed regulating, energy feedback and energy saving.
