Do variable frequency power supplies require aging testing?Is the aging test of variable frequency power supply important?I believe many people overlook this issue when using variable frequency power supplies,that is,not conducting aging tests on them,thinking that this is an insignificant issue.Variable frequency power supplies are commonly used industrial distribution equipment in modern society,and we are very concerned about their various performance and usage.The selection of materials and the control of processes are usually the core elements that affect the quality of the power supply,and there are many factors that affect these core elements.For example,aging phenomenon,the length of aging time during use has a significant impact on the later lifespan and precision confirmation of the power supply.Today,technicians from Quanhua Electronics are here to tell you,do variable frequency power supplies need to undergo aging testing?The importance of power aging testing.
　　Aging testing is the process of testing the performance and accuracy of variable frequency power supply products.The aging time of variable frequency power supply is generally required to be no less than 48 hours.Many manufacturers shorten the aging time without authorization or even ignore the aging process in order to compress time costs,resulting in significant deviations in the performance and accuracy of variable frequency power supply products.
　　1.Damp heat aging:Test the strength change of a variable frequency power supply after rotation in a specified temperature and temperature environment.
　　2.Light aging:The variable frequency power supply is used to simulate natural lighting and other environments,and to generate color changing cracks and physical properties of polymers caused by factors such as photothermal oxygen and shear forces during processing.
　　3.Hot air aging:The hot air reflux aging test is the data obtained by transferring heat energy through the laminar movement of hot air,using a heater and fan to continuously heat up the air inside the furnace,and cycling the test.
　　The intensity of the experiment is much greater than the actual outdoor light intensity,which shortens the testing time.Short term testing can be used to understand the aging situation of the product after many years of use.
　　The core components of variable frequency power supply include:transformer,IGBT module,control module,display screen,chassis,etc.The control of the process mainly includes the assembly process,aging process,and testing process.
　　Transformers should be selected for variable frequency power supply.Whether the copper wires in the transformer are made of high-purity copper materials that comply with international standards,or whether they are made by remelting industrial waste copper,has a significant impact on the conductivity and later lifespan of the transformer coils.
　　The above content mainly introduces the importance of aging testing for variable frequency power supplies from two aspects:materials and processes.It is a key process that tests product performance and accuracy and cannot be ignored.The aging time of the power supply is usually required to be no less than 48 hours.In addition,components are the core components of the power supply,and their testing is also an important part.
　　Aging test is the most important step in detecting variable frequency,which is a test to avoid faults in the variable frequency power supply and other aspects.If there are internal components and other components that have aged,their performance will decrease,which may cause malfunctions and affect work efficiency.
