Product features

High operation reliability

The key processes are produced in dust-free workshop, and the production process is strictly guaranteed;

Strict factory inspection and process control.

Convenient installation and maintenance

The internal main components are modularized and split design, which makes it easy to disassemble between modules, convenient for daily inspection, maintenance and repair, saving time and effort.

It has the function of reactive power compensation

660V, 1140V inverter standard input, output filter reactor, effectively suppress high frequency interference;

The four quadrant inverter is equipped with a special LCL filter to ensure that the interference of the inverter to the front-end power supply and distribution equipment is minimized and meet the requirements of the national standard;

Through the feedback explosion-proof inverter to detect the power quality of the power grid and compensate the reactive power in the line, the problems of low power factor and large line loss in local coal mines are solved. By compensating the loss of power supply line, the energy consumption is reduced.

There are mature treatment schemes for motor insulation damage

The 1140V explosion-proof inverter adopts three-level structure, the voltage rise rate DV / DT is reduced to half of the two-level inverter, the output voltage level increases, the relative amplitude of each level decreases, the voltage change decreases, the current pulsation decreases, which indirectly reduces the electromagnetic interference, greatly reduces the insulation damage of the inverter output to the motor, and effectively solves the problem of motor insulation damage, extend the service life of the motor.

IGBT neutral clamping technology

By clamping the turn-on and turn off of IGBT, the current flowing into or out of the neutral point of DC side capacitor when the output voltage of a certain phase is zero is eliminated. The problems of neutral point potential drift and poor output voltage waveform are solved.

It has excellent power balance function to ensure the balanced output of each motor in the multi machine drive system, and the unbalance degree is less than 3%

It has excellent closed-loop (PID) control function to meet the requirements of pumps

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.
