Huabao Golden Samurai UPS power supply 2020.6.20

UPS uninterruptible power supply is a constant voltage and constant frequency uninterruptible power supply with energy storage device and inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS power supply stabilizes the mains and supplies it to the load for use. The UPS at this time is an AC mains voltage stabilizer, and it also charges the battery in the machine: when the mains is interrupted (accidental power failure) When the time, the UPS immediately uses the power of the battery in the machine to continue to supply AC power to the load through inverter conversion, so that the load can maintain normal operation and protect the load software and hardware from damage. UPS power equipment usually provides protection for both over-voltage and under-voltage.

There are at least nine problems in the power grid: power outages, lightning spikes, surges, frequency oscillations, voltage sudden changes, voltage fluctuations, frequency drifts, voltage drops, and pulse interference: Therefore, from the perspective of improving power quality, equip the load with a UPS Power is very necessary.

With the rapid development of comprehensive mine automation, the demand for comprehensive mine automation is getting higher and higher. More and more computer equipment, microcomputer protection equipment and sensors are used in mine comprehensive automation systems. Once the power supply of these equipment is cut off, it will cause data errors, loss, or even malfunction of these equipment and even the entire mine.

Safety production in coal mining is the basic guarantee for the development of coal mining enterprises, and safety technical guarantee is an important measure to avoid mining disasters. The application of uninterrupted power supply of coal mine fans can improve the stability and reliability of electricity and protect people in coal mining. Property safety is of great significance. The content and type of UPS power system, focusing on the line uninterruptible power system, and the core of the uninterruptible power system in coal mining operations-battery management, put forward relevant suggestions.

The status quo, the current situation of the mine safety monitoring backup power supply system is analyzed; combined with the special application environment of the mine, the key mechanism factors affecting the backup battery failure are analyzed, and the development trend of the mine safety monitoring backup power supply system research is pointed out: That is, optimizing battery selection, optimizing charging technology, monitoring intelligence and self-adaptation, network formation, integration, high density and high frequency, extended standby time, etc., provide new ideas for further research.

Realize the real-time monitoring and display of various parameters such as the voltage of the single battery of the power supply, the capacity of the battery pack, and the balance, and the cyclic capacity self-check and equalization control of all battery packs in the entire UPS power system. And the single power supply is controlled through the CAN bus, which realizes the intelligent mutual management and control of the entire UPS power management system on the bus. This system improves the reliability and power usage efficiency of the UPS power supply in the entire coal mine. Underground UPS power supply in coal mines is the final guarantee for the continuous operation of underground monitoring and life support equipment in the event of a power outage in a coal mine.
