The role of isolation transformers

The main function of an isolation transformer is to completely isolate the electrical components on the primary and secondary sides, as well as to isolate the circuit. In addition, by utilizing the high frequency loss of its iron core, high-frequency clutter can be suppressed from entering the control circuit. Using an isolation transformer to suspend the secondary to ground can only be used in situations with a small power supply range and short lines. At this point, the capacitance current to the ground of the system is not small enough to cause personal injury. Another important role is to protect personal safety! Isolate hazardous voltages.
With the continuous development of the power system, transformers play an increasingly important role as key equipment in the power system, and their safe operation directly affects the reliability of the entire power system operation Transformer coil deformation refers to the axial and amplitude dimensional changes, body displacement, and coil distortion that occur after the coil is subjected to force. There are two main reasons for the deformation of the transformer coil: firstly, it is difficult to avoid external short-circuit faults during the operation of the transformer, and secondly, unexpected collisions occur during the transportation and lifting process of the transformer.
