radio frequency welder Factory.Comprehensive analysis of frequency converter failure of ultrasonic embossing machine

　　With the continuous improvement of the level of science and technology, the birth of new high-power power electronic components, the application of integrated circuits and microcomputer technology, communication frequency conversion speed regulation technology has become increasingly perfect and old. The communication frequency converter speed regulation system has been widely used in metallurgy, petrochemical, electric power, machinery, civil electrical appliances and other work due to its advantages of wide speed regulation scale, fast dynamic response, high precision speed regulation, perfect maintenance function and simple operation.

　　After 6-10 years of normal use, the frequency converter enters the high incidence period of shortcomings, and there are often shortcomings such as burned components, failure, frequent action of maintenance function, which seriously affects its normal work. In the long time engaged in equipment repair work, I have encountered many different inverter shortcomings, in the process of its treatment, found that its shortcomings have certain commonalities and rules. In practice repair, only by grasping its characteristics and grasping the rules of defect treatment, we can do a good job in the repair of the inverter, so that the various shortcomings of the inverter in practice are timely treated and treated, and extend its service life. First of all, according to the technical standard requirements of the frequency converter, the development of perfect daily maintenance methods and maintenance cycles, so that the risk of shortcomings is dealt with in the early stage, especially in the use of frequency converter under harsh environmental conditions, this method is more important. Secondly, it is necessary for professional repair personnel to have a comprehensive understanding of its principle, structure and control methods. In addition, there should be rich practical repair experience and solid electrical theoretical knowledge.
