The noise generated by the toroidal transformer is harmful to the human body. Long-term exposure to such noise may cause damage to the human ear. Everyone knows that the toroidal transformer will inevitably produce some noise during operation. How to minimize the noise to ensure the safety of human body is a problem that customers need to pay attention to. Next, we will introduce the causes of ring transformer noise and specific solutions.
The causes of toroidal transformer noise are as follows:
1. Mechanical noise caused by ring core. The core of the toroidal transformer is made of silicon steel sheet. Under the alternating electromagnetic field, the silicon steel sheet will have magnetostriction, which will cause the ring core to vibrate and cause noise.
2. Noise caused by non-standard processing technology. Toroidal transformers should meet the standard process during the manufacturing process. When winding, the copper wire should be wound tightly and tightly on the iron core of the toroidal transformer.
How to reduce the noise caused by the toroidal transformer?
1. In response to the noise caused by the ring-shaped iron core, an effective method is to use a high-quality cold-rolled silicon steel sheet to seamlessly splice and roll the iron core to make a ring-shaped transformer.
2. To reduce the noise, the customer should choose a toroidal transformer with good quality. The high-quality toroidal transformer with good processing technology has much lower noise.
3. In addition, potting epoxy resin or adding a shield to the middle hole of the toroidal transformer also has the effect of reducing noise.
