As a type of transformer, toroidal transformers are widely used in computers, medical equipment, instruments and lighting. It can be said that toroidal transformers can be seen everywhere in our lives, and have higher cost performance in the process of use. It is a type of transformer that is widely used at present. However, due to some improper operation during use, malfunction or burnout may occur. There are many reasons for the failure or burnout of the toroidal transformer. Today we will discuss several common causes:
1. Over-power use: also called overload use, the load connected to the toroidal transformer exceeds the rated power, and the toroidal transformer will be damaged due to overheating for a long time. When purchasing a toroidal transformer, users must actually test the actual power required by the machine, rather than guessing how many watts the toroidal transformer should be based on their own ideas. It is necessary to fully consider the machine's margin, otherwise it will easily cause the toroidal transformer to use excessive power and burn out.
2. The voltage connected to the input end of the toroidal transformer exceeds 10% of the rated voltage, and the long-term input voltage is too high, causing the toroidal transformer to burn out. For example: the rated voltage of the toroidal transformer is 220V, but the user is connected to the voltage of 260V. The connected voltage is higher than 10% of the rated power of the toroidal transformer, which will cause the primary coil of the transformer to heat up too quickly, shortening its service life and causing damage.
3. Man-made damage. Not everyone realizes that toroidal transformers are vulnerable products. In fact, toroidal transformers are easy to damage. If you accidentally hit it during installation or use, fall off the table, be pressed by heavy objects, etc., this may cause the entire copper wire inside the toroidal transformer to be scratched or broken, causing malfunction or burnout.
In addition to the above reasons, there are some other reasons.For example, the production process is not up to standard, etc. can also cause toroidal transformers to be prone to failure, so users must be sure to identify the toroidal transformer manufacturers with guaranteed quality when buying.
