DESCRIPTION

Product use

BPJ-SF series ventilator with flameproof and intrinsically safe double power and double frequency conversion governor (hereinafter referred to as inverter) is a kind of variable frequency speed regulation equipment with double power and double control system developed for the main and standby two local ventilators in coal mine. The inverter is suitable for the underground coal mine with coal dust, gas and other explosive gas dangerous environment, automatic control of local fan, its unique dual power supply and double frequency conversion system and automatic speed regulation of wind speed according to the gas concentration of the working face, providing a solution for the normal ventilation of underground coal mine fan and hidden dangers in the gas discharge process.

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;

Double power supply double frequency conversion system: with two sets of relatively independent control systems, to achieve the main and standby local fan "double power supply, double frequency conversion" control, can achieve automatic switching;

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;

Automatic speed control function: under the given mode of automatic frequency, the inverter controls the local fan to operate automatically according to the gas concentration signal, so that the local fan works in the state of automatic ventilation, automatic gas discharge or shutdown;

Good energy saving effect: the inverter automatically adjusts the output frequency according to the gas concentration to achieve on-demand wind supply, avoiding a lot of unnecessary energy consumption;

Improving the working environment: when the driving roadway is short and the gas concentration of the driving face is low, the frequency converter can reduce the wind speed at the outlet of the local air ventilator by reducing the output frequency, avoiding the flying of coal dust caused by excessive wind speed on the driving face, thus improving the working environment of the working face.

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;
