DESCRIPTION

Product use

BPJ series mine explosion-proof and intrinsically safe AC inverter (hereinafter referred to as inverter) is a kind of high-tech products integrating vacuum electromagnetic starter and digital frequency conversion speed regulation and related heat dissipation technology. Inverter is mainly used in coal mine with coal dust, gas and other explosive gas dangerous environment, can be used to control AC asynchronous motor and permanent magnet synchronous motor, meet the different motor working mode to achieve the motor heavy load soft start, soft stop and frequency conversion speed control during operation. It has the advantages of low starting current, stable starting speed, adjustable starting time, small impact on the power grid, large output torque and so on. Suitable for small belt conveyor, emulsion pump, water pump, lubrication pump, crusher and other loads.

Main feature

The shell adopts the translation type quick opening structure, heat pipe heat dissipation, small size (the internal modular design), easy and fast operation;

The system is stable and reliable, and the service life is long: the aluminum electrolytic capacitor is replaced by the thin film capacitor, which improves the stability and life of the inverter. The main components are imported, which can ensure the reliability and service life of its long-term operation. The innovative anti-interference and electromagnetic shielding design can effectively reduce the pollution of the power supply system;

All Chinese, LCD real-time display system three-phase voltage, three-phase current, frequency, power factor, active power, reactive power, electrical degree, insulation resistance, switching state, fault information and other parameters;

The variable frequency speed control circuit has the characteristics of large starting torque and smooth start and stop, which can realize the smooth start, speed regulation and stop of AC motor under various load conditions, completely eliminate the mechanical and electrical impact, and extend the service life of the equipment;

With a variety of control modes to choose from, wide range of speed regulation, flexible and convenient speed regulation, strong anti-interference ability, long service life, is the best choice of underground frequency conversion speed regulation device;

When the variable frequency starter is applied to the emulsion pump station and other similar occasions, the output speed of the variable frequency starter is adjusted in real time through the direct torque control and the special algorithm for constant pressure liquid supply, so as to realize the constant pressure of the controlled hydraulic system, save electric energy and reduce the impact on the hydraulic pipeline.

RS485, CAN, Ethernet interface, 4G/5G/WIFI can be configured to communicate with the coal mine power grid monitoring system, with telemetry, remote control, remote control, remote message, remote viewing and other functions, to achieve unattended substation;
