China Education Equipment Purchasing Network News: According to Bitnet, at present, flywheel UPS is very popular in the international market, and the representative manufacturer is American Active Power. With the rapid development of China's data centers, the flywheel UPS produced by Active Power is rapidly entering the public's field of vision, increasing the data center insurance types and insurance coefficients.
The role of UPS power in the data center is just like the insurance that everyone buys, such as auto insurance, life insurance, property insurance and so on. It is the "insurance" of the data center, which can protect customers' most critical assets and the most important data, such as bank credit card transaction information, operator billing information, customer information, etc. These information are the most important assets of users. Once there is a problem with UPS, the user's assets will be lost on a large scale.
For example, if the New York Stock Exchange loses power for one hour, it will lose US $ 1.6 trillion. According to reports, a data center in Texas, the United States, caused an explosion due to a short-circuit of electricity and a fire, which temporarily caused all communications in the computer room Interrupted, and shut down 9000 servers of 7,500 customers, the repair time is expected to take about 24 hours at the fastest. The 9.11 incident in 2001 caused many enterprises that did not make disaster recovery backups to go bankrupt. Without customer information, transaction amounts, and financial records, companies will find it difficult to move forward. So in the current environment where data has become the core asset of the company, UPS is an important insurance for the company. So, how to choose UPS for your data center?
Three reasons to choose flywheel UPS
The first thing to consider is reliability. When driving in winter, this kind of situation is often encountered. The car drove very well the day before. The next morning, because the weather was too cold, it suddenly couldn't catch fire. This situation is often a problem with the battery, which is the characteristic of chemical energy storage. It relies on electrons to generate electrical energy from the cathode to the anode, but this process is not visible or measurable, which leaves a hidden danger for reliability and makes the UPS power supply itself have original defects. At present, a new energy storage technology has appeared on the market, namely flywheel energy storage technology. Its principle is very simple, relying on the high-speed rotation of the flywheel to generate electrical energy, providing power-off protection for the data center. However, the simpler the more reliable. First, the flywheel has mass. Second, the flywheel must produce energy when it spins. If the mass is constant, it is proportional to the square of the speed. It is easy to calculate its energy. In addition, the monitoring system monitors the vertical direction, lateral direction, rotation direction, vibration, and speed of the flywheel. Once the rotation speed or physical conditions change, the user will be reminded in time to ensure the reliable operation of the "flywheel UPS". Therefore, no matter it is calculated from practice and theory, the reliability or the probability of failure of the flywheel UPS is seven times lower than that of the traditional battery UPS. For data center users, it is undoubtedly increased insurance, which is equivalent to buying "All risks".
Secondly, the cost performance needs to be considered. Many users pay more attention to the initial cost when purchasing products, and ignore their subsequent expenses. In fact, today, with rising energy prices, electricity bills are becoming a more expensive resource than products, similar to the difference between universal bulbs and LED lamps. The power supply efficiency of the flywheel UPS is 98%, and the traditional battery UPS is about 92% -93%, which means that the loss of the flywheel UPS is only 2%, and the traditional UPS is about 8%. The flywheel UPS can save energy by 75% compared with the traditional UPS. . Some data show that UPS consumes about 15% -25% of the energy in the entire data center. Based on the above data, it can be reduced by 10% or more by relying solely on "flywheel UPS". For large data centers, the annual electricity savings may reach several million kWh, which is a very large cost for data center operators. The life of the data center is 10-20 years. From the perspective of the entire life cycle cost, the initial equipment cost only accounts for a very small proportion. If we look at the entire life cycle of the data center of 10 years or 20 years, it is "flywheel UPS" instead. Can help users save up to 60% of costs.
Finally, the natural services to be considered, including insurance period, response speed and so on. The life of the traditional battery is generally 3-5 years and needs to be replaced. It is usually charged and discharged. Once the charge and discharge operation is wrong, it will greatly affect the life of the battery. At the same time, we must ensure that the battery runs at a constant temperature, too high or too low will also affect the battery life. Batteries often suffer from uncomfortable operation or explosion due to temperature changes. For the flywheel, this maintenance is not necessary. The flywheel UPS can operate normally between 0 degrees and 40 degrees Celsius, ensuring 24 × 7 × 365 uninterrupted operation. Its life span is up to 20 years, basically meeting the needs of data centers. At the same time, the maintenance of the flywheel is very simple, only need to replace the bearings once every three years, the stability and reliability of the product, and the ease of operation, greatly reducing the cost of maintenance. When there is no risk or the probability of risk is low, the quality of service is also guaranteed. (Zunwen)
