The isolation transformer is a transformer that is electrically isolated from the input winding and the output winding. The isolation transformer is used to avoid accidental simultaneous contact with the charged body. The isolation of the transformer is to isolate the current of the original secondary winding around the coil. It was used in the power industry in Europe for the early years. It is widely used in the power supply, safety lighting and indicator power supply of general circuits in the electronics industry or industrial and mining enterprises, machine tools and mechanical equipment.
A special transformer with high dielectric strength between the primary and secondary windings to isolate different potentials to suppress common mode interference. The ratio of the isolation transformer is usually 1:1.
The main function of the isolation transformer is to completely insulate the electrical of the primary side from the secondary side and also isolate the circuit. In addition, the high-frequency loss of the iron core is utilized to suppress high-frequency clutter from being transmitted to the control loop. The isolation transformer is used to suspend the second ground to the ground, and can only be used in the case where the power supply range is small and the line is short. At this point, the system's capacitance to ground capacitance is not small enough to cause personal injury. Another important role is to protect personal safety! Isolate dangerous voltages.
With the continuous development of power systems, transformers play an increasingly important role as key equipment in power systems. Its safe operation is directly related to the reliability of the entire power system operation. Transformer coil deformation means that the coil occurs after being stressed. Axial, longitudinal dimensional changes, body displacement, coil distortion, etc. There are two main reasons for the transformer coil deformation: First, it is difficult to avoid the impact of external short-circuit faults in the operation of the transformer: Second, the transformer has an accidental collision during the transportation and lifting process.
