Combination controller for explosion-proof winches for mining use

Intelligent Working Surface
Product Introduction:
This integrated controller is suitable for underground coal mines with risks of methane and coal dust explosions. It supplies power to mine-use explosion-proof three-phase asynchronous motors with a rated voltage of 1140 (660) V and frequency of 50HZ, while also protecting the motor and related circuits. It also provides reliable power supply, control, and protection for on-site lighting and signal loads.
Performance Features:
1. The first multifunctional combined
controller for mining in China This product is a mining combination controller device specifically developed for actual coal mine sites, organically integrating multiple products such as lighting, signal power supply, and controller. It is a domestic first and reduces the need for one electrical device in the winch chamber. According to coal mine safety regulations, no grounding grid is needed inside the shaft, reducing construction and improving efficiency.
2. Diverse and comprehensive protection methods to maximize equipment safety
. The product control circuit interlocks the starting of the 127V signal power supply and the starter starter. The starter can only start after the 127V signal power is activated, and once the 127V signal power is disconnected, the starter circuit immediately stops output. All start-stop logics strictly follow the safety operation regulations, fundamentally eliminating illegal operations during underground operations.
3. Quick-open door structure improves maintainability
. The door opening method is changed to a convenient quick-open design, greatly simplifying the installation, disassembly, and maintenance of internal components of the chassis, making maintenance quick and easy. The locking screw and long-distance control lock are made of stainless steel, fully ensuring firmness.
4. Advanced technology with excellent performance, processor leading domestic
similar products. The product uses the most widely used STM32 series embedded microcontroller as the processor. Uses an external 8M quartz crystal oscillator, with a computing speed of up to 72M/s, enabling real-time response to various interrupt requests. Moreover, the chip has a wealth of onboard peripheral interfaces and communication ports, making it easy to expand multiple functional modules.
5. Clean and orderly display screen, efficient and easy
parameter settings. This product displays the device's operating parameters in real time through the LCD, including voltage, current, insulation resistance, temperature, as well as the current operating status of each switch circuit (running or stopped), making it easy for users to promptly monitor the equipment's operating status.
6. Real-time recording of fault data, making it easy for users to query historical data

During equipment operation, when a fault occurs, the product will automatically disconnect and display a fault screen. The fault screen will only disappear when the "Reset" button is pressed after the fault has been effectively resolved. The fault screen not only shows fault types but also real-time action values, making it easy for users to troubleshoot on site.
