How to break the "ice" of UPS power supply application

In recent years, with the increasing application of industrial production automation equipment, computer information systems, etc., the importance of the power platform that supports the operation of these key equipment and systems has also been re-examined. Many examples show that power failure has become one of the most important hidden dangers threatening the normal operation of industrial enterprises. Because in the case of highly automated production and highly informationized operations, even a very short power outage can cause the entire production process to stagnate, products to be scrapped, and even equipment to be damaged. Therefore, improving the reliability of the system is the first issue that enterprises consider in the process of building a power platform. In addition, as the application of power equipment in industrial enterprises becomes more and more extensive and complex, how to save worry and effort and build a power system once and for all has become the focus of people's attention.

UPS: Challenges are everywhere in applications

The extensive application of various advanced equipment in the industrial field has put forward higher requirements for power supply quality and continuity. As an uninterruptible power supply device for all power automation industrial system equipment, remote execution system equipment, high-voltage circuit breaker opening and closing, relay protection, automatic devices, signal devices, etc., industrial-grade UPS effectively guarantees the reliability of industrial automation power supply.

As a high-end product among uninterruptible power supply products, industrial UPS involves power electronics technology for high-power energy conversion, digital control technology, AC power parallel redundancy technology, active harmonic suppression technology, high-power product manufacturing technology, etc. Therefore, it is difficult for general power supply companies to enter this field. Traditional UPS power supplies are often just UPS power supply products that adapt to the industrial natural environment, rather than true industrial power equipment uninterruptible power supplies that adapt to the industrial electrical environment and inductive power load characteristics. In many aspects, they cannot meet the application standards of industrial UPS. Industrial applications have special requirements for UPS:

(1) Must have strong ability to adapt to the environment.

Unlike commercial UPS placed in data centers, server rooms and other environments where temperature, humidity and cleanliness are strictly controlled, it is usually difficult to ensure stable temperature and humidity in the industrial environment where industrial UPS is located. Due to the influence of factors on the production and manufacturing sites, there are common problems such as high temperature, humidity, large amounts of dust, and severe air pollution in industrial application environments. In addition, in special industrial occasions, the air in the environment may also contain corrosive gases, which will affect the normal operation of power supply equipment over time and reduce its working performance. Therefore, this requires industrial UPS to have super environmental adaptability and to cope with the test of harsh environments with comprehensive high performance.

(2) It must be able to effectively eliminate various radio wave disturbances.

The power grid pollution at industrial application sites is very serious, and they often face tight power supply and frequent accidents. The precision production equipment of industrial production lines has always had very stringent requirements on power supply. Power problems such as unstable voltage and current interruption may cause equipment damage or lead to quality problems in product production. Therefore, as the core of the industrial power supply system, high-quality UPS is an important part of power protection. It must have the characteristics of being able to provide high-quality power to the load under any load and mains input conditions, completely eliminate the impact of instantaneous power grid interruptions on industrial equipment systems, effectively avoid high-frequency interference in the power grid, prevent the damage of power grid overvoltage to the load, and ensure the reliable operation of key industrial processes and controls.

(3) It must have an extraordinary load capacity.

In the production, management, monitoring and other links in the industrial field, there are a large number of load devices, especially in the industrial automation production line, which uses a large number of automatic control equipment, DCS, computers, etc., and these loads mostly include inductive loads, capacitive loads, fluctuations and high peak impact loads, etc., which have a great impact on the current. At the same time, among industrial enterprise users, the balanced distribution of load groups is always relative, while the unbalanced distribution is absolute, especially in the production link, the imbalance phenomenon is more serious.
