Flameproof and intrinsically safe frequency converter for ventilators (economical configuration scheme)


Purpose and scope of useApplication and range of application

Suitable for underground coal mines with explosive environments, in an AC50HZ/60HZ, voltage1140V(660V), three-phase neutral ungrounded power supply system. The equipment has the drive control characteristics of a dedicated frequency converter for fans. By adjusting the operating frequency of the ventilator, the purposes of gas emission, air supply according to demand and energy-saving and economic operation can be achieved. It can also automatically adjust and control the air volume according to comprehensive environmental parameters such as monitored gas concentration, carbon monoxide concentration and ambient temperature. It is an automatic drive control device with multiple functions, high efficiency and energy saving, and can be used in conjunction withQJZ-2x120,1140(660) Flameproof and intrinsically safe dual-power vacuum electromagnetic starter for coal mine fans, with the function of automatic switching between two standby units. It can be used in coal minesPower supply and drive control for underground mine axial-flow local ventilators and mine counter-rotating axial-flow local ventilators. The main unit is under frequency conversion control, and the auxiliary unit is under power frequency control of the starter. It is an economical configuration scheme of frequency converter dedicated to coal mine fans.


Product featuresProduct features

Automatically control the air volume, with high efficiency and energy saving, and can be used for multiple purposes. According to the function and parameter settings, the air volume can be automatically adjusted. It has the characteristics of high efficiency and energy saving, saving about 25% of electric energy compared with ordinary fan switches; it has the function of manually setting the air volume adjustment. This product can not only meet the use of local ventilators in coal mines, but also can be used for the drive control of small-power asynchronous and synchronous machines such as water pumps and belt conveyors through parameter settings. The equipment has the characteristics of strong versatility and wide application.


The equipment integrates the monitoring and control functions of gas, carbon monoxide and ambient temperature. The equipment is integrated with monitoring ports for T1, T2, T3, CO and temperature, as well as the functions of wind and power interlock and gas and power interlock. It has the functions of real-time high-speed acquisition, analysis and processing by PLC. By monitoring the concentration of various dangerous gases and the ambient temperature, and adjusting and controlling the output of the frequency converter according to the set value, the purpose of automatic air volume control or shutdown is achieved. The equipment has a compact structure, which improves the integration, reduces the number of equipment and saves the cost.


Good temperature rise control and high safety and reliability. The core components of the frequency converter, such as IGBT, use a new generation of power modules with high drive density, low temperature rise and long service life. The core and peripheral control components such as IGBT, PLC and control relays are all selected from internationally well-known brands, thus ensuring the overall performance and service life of the product; the driver has various protections such as short circuit, overload, overvoltage, undervoltage, phase loss, overheating of the IGBT module and ambient temperature monitoring, and provides intuitive text and status display, ensuring the safety and reliability of the product in use.


Excellent performance and good dynamic speed regulation performance. It has control modes such as V/F, open-loop vector, and closed-loop vector, providing stable and reliable driving; It has a wide speed regulation range and good dynamic and steady-state performance. It is equipped with a built-in PLC programmable controller, which has the function of accessing and monitoring environmental monitoring sensors such as CH4 and CO. It can perform automatic speed regulation control according to the air supply volume requirements, with obvious energy-saving effects.


Friendly human-machine interface and convenient operation. The frequency converter uses a 7-inch full-Chinese liquid crystal touch screen combined with a 16-key matrix keyboard for operation, which is convenient for debugging, operation, and querying. The main and standby units can be switched with one key. It has functions such as basic data, operating status, operating data, fault text, trend records, and information storage. The system is also equipped with a frequency converter keyboard control panel for emergency backup system control.
