The role of single phase isolation transformer

The input and output of single-phase isolation transformer are AC voltage, usually used in industrial control equipment, household appliances, instruments, etc., it has the advantages of simple structure, high reliability, fast response, etc., and can play a role in a wide range of applications.

First, functional features:

1, anti-interference effect: such as through the Y/△ connection of the isolation transformer, can prevent part of the harmonic transmission;

2, impedance conversion function: increase the system impedance, so that the protection device is easy to cooperate;

3, the role of stabilizing the system voltage: such as starting large load equipment, reduce the impact on the system voltage;

4. The function of preventing system grounding: when single-phase grounding occurs on the load side of the isolation transformer, it will not cause single-phase grounding of the entire system (above the Satons isolation transformer);

5, reduce short circuit current: when a short circuit accident occurs on the load side, limit the short circuit current of the system.

The power transformer 5WEI41-20 AC 220V conversion single and double, the output current is 6V, 9V, 12V, 15V, 18V, 24V, 36V, 48VAC.

Second, because the single-phase isolation transformer is a power type device, it will generate a certain amount of heat during work, so it is necessary to take appropriate heat dissipation measures and pay attention to maintaining good ventilation. At the same time, it is also necessary to be equipped with appropriate protection measures, such as overload protection, short circuit protection and overvoltage protection, to ensure the safety and reliability of the equipment.

In addition, it is also necessary to pay attention to the adjustment range and accuracy of the single-phase isolation transformer, as well as the performance and reliability of the controller. In the design and selection, the appropriate model should be selected according to the actual needs and characteristics of the application, in order to obtain the best control effect and performance.
