Does the transformer emit radiation?

Everyone must be familiar with transformers. When studying physics in high school, we have to learn the principles of transformers in detail. In addition, we often come into contact with transformers in life. In addition to some larger transformers that can be seen outdoors, many electrical appliances in life actually have transformers. There are many types of transformers at present. Everyone needs to master some knowledge of transformers. So, will transformers produce radiation?

Does the transformer emit radiation?

First of all, the transformer must have radiation. During operation, the transformer will generate not only environmental noise but also electromagnetic radiation. If this electromagnetic radiation exceeds the prescribed energy limit, it will cause electromagnetic radiation pollution. Electromagnetic radiation pollution can cause many hazards, among which the main harm to the human body is causing autonomic nervous system dysfunction, blood pressure and blood phase disorders, and even eye damage.

The transformer is a radiation source. Compared with the high-frequency transformer, the radiation of the industrial frequency transformer is not very serious. However, the power of this power transformer is very large and the electromagnetic radiation is also very strong, so it is best to stay away from it.

Generally speaking, transformers must be shielded to isolate electromagnetic radiation from the outside world. This power transformer is completely open. It's okay to be around this thing once or twice, but it's okay to be around this thing for a long time. For the sake of your health and future generations, it's best to stay away from it.

How many meters of transformer radiation is harmful

The electromagnetic radiation of ordinary distribution transformers is not large, and the metal casing can shield a considerable part of the electromagnetic radiation. Generally, the intensity of electromagnetic radiation is negligible when the distance from the transformer is more than 5 meters. If you are only staying for a short time, it is sufficient to ensure sufficient insulation distance. For example, the distance in the air from a bare conductor with a voltage of 10kV should be no less than 150mm.

The harm of transformer radiation to human body

During operation, the transformer will generate not only environmental noise but also electromagnetic radiation. If this electromagnetic radiation exceeds the prescribed energy limit, it will cause electromagnetic radiation pollution. Electromagnetic radiation pollution can cause many hazards, among which the main harm to the human body is causing autonomic nervous system dysfunction, blood pressure and blood phase disorders, and even eye damage.

In addition, the distance of transformer radiation is related to power, and the extent of the impact is still being demonstrated. The general conclusion is that infants, pregnant women, the elderly and patients are most affected. They should be kept close to home, but for safety reasons, it is best to stay away. Here is some relevant knowledge in this regard.

According to the relevant regulations on the protection of power facilities, for a 110 kV substation overhead transmission line, its protection area is 10 meters outside the line. In other words, as long as it is 10 meters away from the power line, the safety of electromagnetic radiation is guaranteed. For 220 kV and 500 kV transmission and transformation system wires, the protection areas are 15 meters and 20 meters respectively.
