What should I pay attention to when customizing R-type transformers?

What should we pay attention to when customizing a transformer? For technicians, the requirements and parameters of customizing R-type transformers are very clear, but for purchasing personnel, because they do not have so much technical expertise, they do not even understand some basic parameters. When encountering such a situation, there will be some difficulties in docking, resulting in inaccurate parameters and the product cannot be used after being taken back. Let us take a look at some basic parameters of the transformer and its main functions.

To customize a transformer, you first need to know the voltage ratio you are using. The required voltage ratio is different in different usage scenarios and different devices. What is the transformation ratio of a transformer? The transformation ratio refers to the voltage ratio or current ratio, which is the voltage or current ratio between the primary winding resistance and the secondary winding resistance. The voltage ratio of the primary and secondary windings of the transformer is equal to the ratio of the number of turns of the primary and secondary windings, so if you want different voltages for the primary and secondary windings, just change the number of turns. Transformer step-up: For the support transformer, the secondary side voltage decreases as the primary side voltage increases, but the voltage across the primary side winding must be the rated value. If the external voltage is slightly higher than the rated voltage, the current through the primary winding will increase greatly. At this time, if the wrong line is connected, the transformer will burn out.

What is the rated power of a transformer? The rated power refers to the efficiency of electrical equipment when used at rated voltage. The rated power of electrical equipment is designed at the factory, but the power used in different application scenarios and different equipment will be different. At this time, we need to customize the rated power of the transformer according to our needs.

What is the role of rated current? Our daily fires or electrical burning are usually caused by current. When current passes through, it generates heat, and excessive heat accumulation can cause fire or electrical burning. Generally speaking, our electrical equipment will be marked with the maximum use current, which means the maximum instantaneous current that the electrical equipment can withstand. If the current runs for a long time and the transformer has no protection settings, it will cause damage to the electrical equipment. If the current exceeds the maximum current, the electrical equipment will burn immediately.

The above are some basic parameters of customized transformers and their functions. For transformers, if used improperly, each seemingly simple parameter can cause serious harm. Therefore, when purchasing or customizing a transformer, you must clearly understand your actual usage, otherwise the product will not work, which will be time-consuming and laborious.
