Technology is more and more developed, wireless charging replaces wired charging, simple and convenient. Wireless charging technology has obtained 20 patents in 2007. A variety of devices can use a charging base station, mobile phones, MP3 players, power tools and others. The wired charging status of the power adapter will not be there. However, does wireless charging affect the human body?
Does the wireless charger have radiation? Is the wireless charger radiant to the human body?As an electronic charging product, the charger itself cannot avoid radiation, so it is inevitable that the wireless charger has radiation. However, the power of the wireless charger is small, the charging time is long, and the generated radiation is also small. Within the safe range, the magnetic field generated by the charger is very weak, and it can charge the device without affecting nearby credit cards, video tapes and other items that use magnetic recording data. However, try to avoid direct contact with the charging platform when charging. In fact, the wireless charger product is an electronic device that works in ultra-low frequency. The product specification file of the wireless charging alliance shows that the operating frequency of such a wireless charging product is in the low frequency range of 50-60HZ, and the body reacts strongly to the electric field, but The body's response to magnetic fields is almost non-existent, so this system does not affect human health. Therefore, the electromagnetic radiation generated in theory is equivalent to ordinary small household appliances. Moreover, this standard is lower than the electromagnetic field exposure limit issued by the International Commission on Non-Ionizing Radiation Protection for public contact products, so it is safe for the human body and need not be ignored.
If you are still worried about this, you can only recommend using or losing electronic equipment. Because some experts pointed out that "the radiation is not only wireless chargers. Now users are exposed to more and more radiation: computers, tablets, mobile phones, WiFi, TV, microwave ovens... superimposed radiation is very high. Long-term life is high Radiation environment may cause health hazards."
Therefore, in order to prevent the radiation superposition effect, various electronic devices in the home and office should be dispersed, and try not to use them all at the same time.
An electric slip ring is a rotary electrical connector. It allows uninterrupted power or signal transfer between two stationary points. It is also known as an electric Rotary Joint, power swivel, or electrical rotary joint. Electric slip rings are usually composed of a metal ring with several brush contacts on the inner circumference. And there are one or more pairs of contacts for power or signals on the outer circumference. The metal ring can be rigid or flexible, depending on the application.
An electric slip ring is an electromechanical device that allows the transmission of electrical power and signals from a stationary to a rotating structure. It consists of an electrically conductive rotating disc or ring, with a number of electrical contacts (or "slots") on its surface. The contacts are connected to external circuits, enabling the passage of power and/or data from the stationary to the rotating structure. Slip rings are also used in generators, where they allow the passage of current from the rotor to the stator.
A flat disc electrical slip ring is one kind of electric slip ring, it has many advantages: simple construction, small size, low cost, easy installation, and maintenance. It is widely used in various fields such as machine tools, textile machinery, printing machinery, packaging machinery, medical equipment, and aerospace equipment.
A 360-degree rotating Conductive Slip Ring is also called a hollow shaft slip ring or hollow conduct. It has an opening in the center that allows a shaft to pass through, making it ideal for rotating applications. Slip rings are often used in medical equipment, robotics, and manufacturing assemblies where rotation is required. This type of slip ring can handle large currents and voltages while providing a continuous electrical connection.
