Now the smart phone basically has to be charged every day, I believe that many people are convenient, the charger is plugged in the row every day. When we get home from work, we can charge it with a plug-in, without having to find a charger and plug it in.
This is indeed very convenient and convenient, but there are also great risks. No, there is an owner in Hezhou, Guangxi, who did not unplug the charger when he left home, resulting in a fire in his home. Fortunately, the property found the fire in time, and used the fire hydrant to extinguish the fire after breaking the door to avoid causing greater losses.
After netizens saw the news, they all said that they did not like to pull the charger. Brain Dongjun couldn't help but look at his charger. In fact, many people in life have never unplugged the mobile phone charger body and have been plugged in the row plug.
Firefighters also caution that this behavior is not right! Many fire accidents occur because of some inconspicuous fire hazards. I hope that everyone will keep in mind the knowledge of fire safety, and fire safety cannot be ignored!
Charger is not pulled on the row plug, which is a very common thing in our eyes. So why is it a fire hazard? How dangerous is it? Old rules, please readers move your small hands to make a fortune, give the author a free like and attention, thank you.
Perhaps some friends think that the charger is not pulled is not a big deal. After taking the phone away, the charger does not work, there is no current in it, and it is difficult to cause a fire.
In fact, when the charger is unloaded, there will also be current inside, and it is still in working state. Our mobile phone charger can be seen as a small transformer, which can turn the voltage of 220V into a low voltage that can charge the mobile phone.
It has two parallel coils inside, the working principle is magnetic field induction; when the current passes through, a magnetic field is generated, and then a direct current of different voltages is generated, which is then delivered to the mobile phone at the other end.
Even if the charging is not charged, as long as the charger is not unplugged, the coil connected to the power supply still has current passing through, because the principle of the charger is magnetic field induction, the coil is a loop, and there will be a process of converting electrical energy to the magnetic field. So, even if the phone is not connected, the charger is working.
That is to say, as long as the charger is plugged in the row plug it will always consume power. It is only because the power of the no-load is relatively small, and the power consumption is not very large. Someone once did a test, the empty charger only consumes 1.5 degrees of electricity a month, an extra two dollars of electricity bill. Power consumption is a trivial matter, and the real hidden danger is that the charger is still working, and there is current inside.
In the long-term power state, the internal electronic components of the charger accelerate the aging and shorten the service life of the charger. What is more frightening is that the aging of electronic components may lead to the explosion of the charger and ignition, and finally cause a fire.
We all know that when the mobile phone charger is working, there will be a little heat; especially now that the mobile phone is fast charged, it can be fully charged in twenty or thirty minutes, and the fever is very serious.
As mentioned earlier, the charger is working even when it is unloaded. If you keep plugging in the socket, there will always be a current passing through, and it will heat up slightly after a long time. This in turn affects the electronic components inside, and the problem of electrolytic capacitor explosion may occur, and then cause a fire.
The charger produced by regular manufacturers, such as the original charger equipped by the manufacturer, or the official charging head purchased separately, the quality is guaranteed, and the safety hazard is not so large. If it is a mobile phone charger produced by those three small workshops, the quality is not good, and the heat is serious without charging, then the problem is big.
Once the charger explodes or shorts circuit due to overheating, it can ignite the flammable materials around it, causing a fire. In recent years, the news of fire caused by not pulling the charger should have been seen a lot. Even some inferior chargers will explode when charging, and the safety hazards are not small.
Therefore, everyone must develop good habits and unplug the charger when going out. At the same time, it is necessary to buy a regular and compliant charger, and do not covet a charger that does not pass the quality of the cheap.
