Three layer insulated wire introduces how to take emergency measures for electric shock
Date：2021-11-26
What about electric shock? Next, the manufacturer of three-layer insulated wire will introduce it to you.
(1) principle: first aid for electric shock must last minute and second.
(2) anyone who finds electric shock shall immediately separate the wounded from the power supply. Disconnecting from the power supply is to disconnect the switch, knife switch or other disconnecting equipment of the live equipment contacted by the electric shock. In the process of disconnecting from the power supply, rescuers should not only save people, but also protect themselves. Do not touch the wounded directly with your hands before electric shock.
(3) if the electric shock is at a high place, it will rise automatically after the electricity is released.
(4) if the person who gets an electric shock contacts low-voltage live equipment, cut off the power supply as soon as possible, such as pulling off the power switch or knife switch, unplugging the power plug, etc; Or use insulating tools, dry sticks, boards, ropes and other non-conductive things to relieve the electric shock; You can also hold the clothes that are dry but not tight and drag them away. Remember to avoid touching the body of the electric shock; You can also wear insulating gloves or wrap the insulated electric shock with dry clothes;
(5) if the person who gets an electric shock contacts high-voltage live equipment, cut off the power supply or use insulating gloves. During rescue, rescuers must keep a safe distance from themselves and surrounding electrical equipment < p > 6 after leaving the power supply, if the person who gets an electric shock is sober, he should lie on the ground and stop temporarily; In case of unconsciousness, lie flat in place and keep the respiratory tract unblocked. Shout the wounded or pat him on the shoulder within 5 seconds to judge whether the wounded has lost consciousness. It is not allowed to shake the injured person's head to call the injured person. And immediately dial "120" for help. When asking for help, the accident site or sign building, the injury condition and the name of the person asking for help shall be clearly displayed, and the ambulance shall be received nearby.
(7) if the injured stops breathing and heartbeat, appropriate life-saving measures should be taken according to the cardiopulmonary resuscitation method (unblocking the airway and manual external chest pressure), and local life-saving measures should be implemented in time during the rescue process.
The above is the introduction brought by the three-layer insulated wire. If you have any other questions, please call us.
Why is the coil of three-layer insulated wire not prone to short circuit fault
The coil is surrounded by copper core wire without current blocking element. Why is such a coil not easy to short circuit? Next, a small series of three-layer insulated wires will be introduced to you.
1. Copper core resistor
Although the copper core wire has three anti paint, it is only an electrical conductor and has no electronic components, so many people will feel the current or may have a short-circuit fault. In fact, according to the law of resistance, r = PL / s, we can know that the smaller the cross section of an electrical conductor, the greater the resistance. The longer the wire, the greater the resistance. However, the copper core wire used for the coil is thin and long, and its resistance has long become larger. Therefore, when the on-line diagram supplies DC power, it will not have short-circuit fault.
2. Impedance angle generated by spiral winding
The positive winding copper core wire can also continue to block the AC current. It can quickly convert the azimuth current and make the coil form a rapidly changing electromagnetic field, so as to form an "impedance angle". The winding resistance angle is directly proportional to the induced current generated by the coil, and the induced current of the coil is positively correlated with the square of the number of turns of the coil. Therefore, the manufacturer of three-layer insulated wire found a coil wound on the copper core wire. There was no short-circuit fault in the AC current, but an inductor was generated.
3. Maintenance of three proofing paint
The three proofing paint can ensure that the current can be wound along the winding direction of the copper core coil, and can be transmitted for one cycle, so as to ensure that short-circuit fault is not easy to occur.
The above is why there is no coil short circuit in the three-layer insulated wire. Later, we will bring it to you regularly. If you are interested in relevant products, you are welcome to contact the merchant.
