The breakdown voltage of the silk-covered wire is only a few hundred volts, and the breakdown voltage of the enameled wire is several thousand volts. If the insulation is no problem, I think it can be exchangedYes.
◆ Enameled wire is an insulated wire coated with paint, so it can be wound into a variety of shapes of coils used in a variety of electronic devices, without producing the phenomenon of short circuit between wires. ● If it is not enameled wire, but a wire wrapped with other insulating substances, such as gauze wire, silk wire, insulating sleeve pipeline, etc., can also be used as a coil.
The materials usually used for winding transformers are enameled wire, sandbag wire, silk-covered wire, and the most commonly used enameled wire. The requirements for the wire are good conductive performance, sufficient heat resistance of the insulating paint layer, and certain corrosion resistance. As we use this Novo electrical equipment, the win-win transformer, all use high-strength polyester enamelled wire.
The transmitting end is often multiple strands of silk-covered wire, multiple strands of thinner enameled wire or gauze wrapped wire wound inductors are used in relatively high frequency circuits, such as the magnetic antenna rod coil of the radio, the shortwave radio coil, the high frequency transformer coil of the liquid crystal display lighting circuit, etc., often use multiple strands of wire and wound.
Materials usually used for winding transformers: enameled wire, gauze wire, silk wire, paper wire, the most commonly used enameled wire. Insulating material: In wound transformers, coil frame layerInsulation materials should be used between the isolation and the isolation between the winding, and the general transformer frame materials can be made of phenolic cardboard, epoxy board and cardboard.
Wireless charger refers to the use of electromagnetic wave induction principle for charging equipment wireless charging special enamelled wire , the principle is similar to variable voltageA surname There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate an electromagnetic signal, and the receiving end coil senses the electromagnetic signal of the sending end to generate a current to charge the battery.
Wireless charging emission Circuit Board (PCBA) is an electronic component used to implement wireless charging function. It is one of the core components of the wireless charging system, responsible for converting electrical energy into wireless energy signals and transmission. PCBA usually consists of multiple components, including power supplies, inductors, circuit control chips, filters, and connectors.
Oscillators and modulators
At the exhibition, Fulton Innovation, a subsidiary of Amway Corporation of the United States, demonstrated wireless charging technology and launched the world's first wireless charging TeslaPull the car.
No. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. Wireless charging technology uses magnetic resonance to transmit electrical energy in the electric and magnetic fields between the charger and the device, and the coil and capacitor form a resonance between the charger and the device.
The steps are as follows: First, connect the USB data cableCut off the end of the phone with scissors or a knife, and then cut a short section of the long end of the data cable into the incision. At this time, you will see four green, red, white and black wires. Cut off the green and black two, and cut off a small section of the insulation layer of the red and green two, respectively, to expose the copper wire.
1, all coil windingIt's all enamelled wire. If it's not enamelled, it shorts out. Enamelled wire generally selects the diameter of the line, which is the thickness.
2, problem four: How to make mobile phone wireless charger All the coil winding is enameled wire. If it's not enamelled, it shorts out. Enamelled wire generally selects the diameter of the line, which is the thickness.
3, first prepare three Dongdong: one is the United States wireless coil, one is the United States wireless charger also known as wireless energy disc, two lacquer bag money. To do a modification requires a certain amount of hands-on ability and hands-on equipment, such as: multimeter, electric soldering iron and solder.
