When many customers purchase isolation transformers, they will wonder what is the difference between isolation transformers and common transformers, and how to choose different types of transformers. Today, I will explain the difference between isolation transformers and common transformers.
(1)The main tasks are different:
The main task of common transformer is to change the voltage, which is divided into step-down transformer and step-up transformer. The turns of primary and secondary coils are not equal. Isolation is not its main task, even some of the primary and secondary sides of the transformer are not isolated, such as auto transformer is typical.The main task of isolation transformer is to separate high voltage from low voltage, strong current from weak current, so the most basic requirement for it is to ensure the insulation performance of the primary and secondary sides. In this way, when the human body contacts any line of the transformer, there will be no electric shock accident. Even some isolation transformers have the same or nearly equal number of primary and secondary side turns. For example, in order to maintain the color TV set safely, the 1:1 isolation transformer commonly used does not have the function of voltage transformation.
(2)Different usage:
The isolation transformer is mainly used to isolate the power supply from the load, so that there is no direct electrical connection between the two sides. Generally used in low-voltage instruments and experiments. common transformers are controlled according to the required voltage and current levels of electrical equipment within a required range of use.
The above is the difference between the two. In short, the isolation transformer plays the role of isolation, and the common transformer mainly changes the voltage, so I believe everyone has a clear understanding of the difference between the two. I hope you can buy a suitable transformer based on the difference between the two and the actual situation when you buy a transformer in the future.
