The difference between isolation transformer and control transformer

Isolation transformer and control transformer are two types of transformers commonly used in power systems. Although they work similarly, they have some distinct differences. This article will detail the differences between isolation transformers and control transformers.

1. Definition and function

Isolation transformer is a commonly used power equipment. It is a power device that completely isolates and separates the power supply at the power supply end into one power supply, and then transmits it to the load end. . The main function of the isolation transformer is to transform the input voltage to isolate the output voltage from the input voltage. Isolation transformers are usually used to isolate low-voltage power supplies and equipment, amplify signals and suppress noise.

Control transformers are transformers used to process and control current and voltage. The control transformer can output different voltages by transforming the power supply. Control transformers are commonly used to control motors, relays, lights and other household appliances.

2. Structure

Isolation transformers usually consist of a magnetic core, a series of coils and insulating components. The input and output ends of the isolation transformer are completely isolated, with high electrical isolation and effective isolation effect.

The main structure of the control transformer consists of the same magnetic core, input coil and output coil. The output coil is composed of sliding transformers, capacitors, resistors and other circuit components, and controls the input electrical signal or output signal to make the output voltage meet the needs.

3. Application

Isolation transformers are suitable for many different applications, such as battery chargers, starters and other electronic applications. In these applications, the use of isolation transformers can help Protect your device from additional interference and interference. Additionally, in AC circuits, an isolation transformer can prevent circuit damage due to shorts between ground and fluid.

Control transformers can use control circuits with physical control voltages that can change the speed and position of electrical equipment to suit a variety of applications. Control transformers can be used in industrial and civil applications, such as automobiles, construction machinery, and lighting.

4. Maintenance and protection

The main protection and maintenance methods of isolation transformers are not too complicated. Isolating transformers must be inspected and cleaned regularly to ensure that their functionality is not impaired. In addition, when using an isolation transformer, attention must be paid to its rated current and frequency, and these parameters must not be exceeded. Otherwise, the isolation transformer may be subject to electrical or magnetic damage.

The protection and maintenance of control transformers need to be more careful. When installing and maintaining control transformers, the correctness of their circuits and electrical installations must be ensured. Additionally, control transformers must be isolated within rated voltage and load current to avoid damaging circuit components and causing equipment failure.

Isolation transformer and control transformer are two different types of transformers. Although they have similar working principles, their structures and applications are slightly different. When choosing which transformer to use, the choice must be based on the specific requirements and technical requirements of the application.
