Isolation transformer and ordinary transformer difference

Many customers in the purchase of isolation transformer, will wonder what is the difference between isolation transformer and ordinary transformer, do not know how to choose different types of transformer, today Xiaobian will give you to explain the difference between isolation transformer and ordinary transformer.

The main tasks are different:

The main task of ordinary transformer is to change the voltage, divided into step-down transformer and step-up transformer, the number of turns of the original secondary side coil is not equal. Isolation is not its main task, and even some transformers are not isolated, such as autotransformer is typical.

The main task of isolation transformer is to separate high and low voltage, strong and weak current, so the most basic requirement for it is to ensure the original side insulation performance. In this way, the human body in contact with any line of the transformer, there will be no electric shock accident. Even some isolation transformer original side turns equal or close to equal, such as in order to safety maintenance color TV commonly used 1:1 isolation transformer, does not have the role of transformer.

Isolation transformer is mainly to isolate the power supply and the load, so that there is no direct electrical contact between the two sides. Generally used in low pressure instruments and experiments. Ordinary transformer is based on the voltage and current required by electrical equipment, control them in a required range of use.

Above is the difference between the two summed up by Xiaobian, in short, the isolation transformer plays an isolation role, and the ordinary transformer is mainly to change the voltage, so I believe that we have a clear understanding of the difference between the two. I hope we can buy transformers in the future, according to the two differences and the actual situation, to buy the right transformer.
