Does a HV transformer have radiation? Is it harmful to the human body? How much impact does a high-voltage transformer have on human health?
HV transformer will also produce radiation during the working process, but this radiation is not particularly large, basically negligible, for example, if the distance is more than 5 meters, the intensity of the radiation is very low.
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 electromagnetic radiation.
Generally, the intensity of electromagnetic radiation is negligible if it is more than 5 meters away from the transformer. If it is only a short stay, as long as sufficient insulation distance is met. For example, the distance from a bare conductor with a voltage of 10kv in the air is not less than 150mm.
Safe distance between HV transformer and house
The minimum safe distance around the indoor and outdoor transformers is generally stipulated as follows: the minimum distance between the outdoor transformer and its surroundings should not be less than 0.8m.
2. According to the "Code for Design of 10kV and Below Substations" (GB50053-94), the minimum electrical safety gap between the exposed live part of the 10kV transformer and the ground (floor) surface is 2.7m.
3. Answers from transformer manufacturers. Under different standards, the safe distance between a 10kV transformer and a house has different values: for example, 0.7m (minimum safe distance), 1.5m (power facility protection requirements), 5m (construction site requirements), 6.5m (the distance between the overhead line and the house), etc.
How much is a HV transformer
There are also many types of transformers. There are industrial transformers and household appliances. Industrial transformers tend to be larger and more expensive, and the general household transformers are small transformers, and the price is quite cheap. The prices corresponding to transformers of different materials are also different. Everyone must be curious about how much a transformer is. 250 transformers are about 100-150 yuan (the price comes from the Internet, for reference only), mainly depending on the power and the brand, the transformer ( Transformer) is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil, and the core (magnetic core). The main functions are voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. The price comes from the Internet and is for reference only. The actual price shall prevail.
The structure and function of HV transformer
The structure of the high-voltage transformer is simple. The internal structure is mainly composed of an iron core, primary winding, and secondary winding. Although there are only three small parts, they have a great effect. The core of high-voltage transformers is generally made of silicon steel sheets. But silicon steel is a silicon-containing steel with a silicon content of 0.8-4.8%.
A high-voltage transformer is a transformer that uses electromagnetic induction to convert low voltage into high voltage. It is also used in medicine such as X-ray machines and high-potential therapeutic equipment. Not only that, but it is also widely used in printing and electrostatic treatment. Microelectronics static removal, High-voltage transformers are naturally indispensable for air purification and oil fume treatment.
The high-voltage transformer is an electronic device commonly used in electronic products. It is an electromagnetic induction device used to convert low-frequency low voltage into low-frequency high voltage. The transformer manufacturer tells you that when the primary side winding passes through alternating current, the transformer generates an alternating magnetic field, and through the induction of the alternating magnetic field, the secondary winding also generates an alternating magnetic field to generate an AC electromotive force. The voltage level of the secondary winding is related to The turn ratio of the secondary winding is related, that is, the voltage is proportional to the number of turns. The main function of high voltage is to convert low voltage into the required high voltage. Insulation is particularly important in the production process. The quality of many manufacturers' products is not qualified. In terms of insulation treatment, good insulation is the most important thing in the manufacture of high-voltage transformers.
