Industrial UPS power system, as the basis for the normal production and operation of industrial enterprises, provides reliable power protection for the safe and continuous operation of a large number of advanced industrial production equipment and information systems, and plays a very critical role in these fields.
Problems caused by power quality are extremely common in the industrial field. Especially for the semiconductor industry, it can be said that the quality of UPS uninterruptible power supply is the key to production. Problems such as instantaneous interruption and harmonics will make the entire batch of materials waste, which is costly. For these companies, the quality of electricity used in production is getting closer and closer to the level of the information field.
With the in-depth application of information technology in production, operation, management and other aspects of the industrial field, as well as the large-scale application of high-end and precision equipment, the industrial field has put forward higher and higher requirements for the quality of power supply, which not only requires the continuity of power supply Reliable guarantee, and there are special requirements for the purity of the power supply. In this context, UPS uninterruptible power supplies are widely used in industrial fields due to their high voltage stabilization accuracy and the ability to uninterruptedly provide pure power to the load, providing reliable power guarantee for industrial production and management.
With the rapid economic development, the equipment is also highly likely to suffer from other surge interference from the line (for example, the operating overvoltage phenomenon caused by various power equipment to the power grid when the power equipment starts operation), and its impact on the equipment may be Bigger. Therefore, it is obviously incorrect to simply and intuitively assume that "no overvoltage protection is not needed without lightning". It can be said that the current overvoltage protection work has shifted from the traditional lightning protection to the comprehensive protection of direct lightning, lightning electromagnetic pulse, ground potential counterattack and operating overvoltage.
