What is the composition and principle of current transformer

The current transformers that people use now are all made of iron cores and windings. The principle of making the transformers is relatively simple. The design is completed through the principle of electromagnetic induction. In order to operate with small current on the secondary side, the transformer can be installed in the environment that needs to be measured and used. Now the types of transformers have also begun to increase. When people choose transformers, they can combine the composition and principle for application. Good application purpose.

When selecting a current transformer, it can be distinguished according to the insulating medium, including dry-type transformers and casting-type transformers, etc. Dry-type transformers are made of ordinary insulating materials, and the external Other protective treatments can achieve better insulation effect. The material of casting transformer is different from that of dry transformer. This transformer is made of epoxy resin and other materials. Therefore, when purchasing transformers, they can be selected according to the characteristics of this classification.

During the use of the current transformer, it can also be distinguished according to the installation method. The through-type transformer can be used for application. This transformer can pass through barriers such as walls during the use phase, while the pillar-type transformer needs to be installed in the fixed installation. It is completed on the plane. At this time, the user should select the transformer according to the characteristics of the installation environment.

When purchasing and using current transformers, there are many types of transformers. Users need to pay attention to a simple understanding in the process of purchasing and using current transformers, and clarify the differences in installation and application of different types of transformers. These are not acceptable. ignored issues.
