Yesterday, my dad said that my computer was powered. I thought it was okay because I was often powered and thought it was just static electricity.
Is it static electricity? Today, I tested it with a digital measuring pen, and it was so scary. The steady "AC v" is the number on the metal plates of the chassis, the same is true for connecting to a broken USB interface (now I know why it is broken ).
What's even more dumb is that the power of the plug-in board is off during my test, but its plug is still plugged in with an external power supply.
The socket has a big problem.
I unplugged all the plug on the wire board and tested the Jack of the socket one by one using a power measuring pen (still "off" the power supply ), it is found that all the zero wire and FireWire holes are 220 V (that is, the power off), and a ground Jack is also v.
(
Note:This outlet is produced by the Shanghai "HSBC" electronics company. I don't know if it is fake. It's unlucky to buy such a "monster .)
I have been using this plug-in Board for four years. I am lucky that I have not been killed by it.
Later, I changed a seemingly strong socket, tested the computer chassis, and jumped out of 36 V, but it immediately disappeared, so the "static electricity" was decent :)
// Warning:
If&&Your outlet price is <20 RMB or sent when you buy a computer)
{
It is best to have a digital measuring pen to check the socket;
}
Otherwise
{
It may be killed by a socket-Not worth it;
}
Cherish life and use electricity safely!
