Tips: Functions of ATO 3 phase isolation transformer
The main function of three phase isolation transformer on ATO.com is to fully insulate primary and secondary electricity and circuit. In addition, its iron core has great ability of high-frequency clutter rejection with the features of high-frequency and great loss. Isolation transformer commonly known as safety transformer is usually used to isolate high-frequency clutter from entering control loop.
Isolation transformer is designed for personal safety in the use, maintenance and commissioning of certain electrical appliance. Taken fixing a color TV as example, the power supply of the color TV is directly rectified into machine, so the chassis of machine could be charged. If a maintenance man cursorily touches this part circuit, he will get an electric shock that endangers his personal safety. In the process of inspection and testing, if the connection between instrument grounding and chassis may cause power supply short-circuited, resulting in the damage to transistors, integrated circuits and test equipment inside machine. Therefore, 3 phase isolation transformer should be used for the maintenance of certain household appliances.
