How to prevent static discharge from hitting
In daily life, people often cause static accumulation in the body due to wearing, climate, friction, etc., and when they suddenly touch metal, they will feel the pain of electric shock, and sometimes cause some psychological pressure when a certain stage occurs frequently. . If you temporarily avoid contact with the iron, your body's charge may accumulate more, and sooner or later you will receive a greater electric shock.

1. In the house, static electricity may be generated after the carpet and the sole are rubbed, and the body may be charged due to wind blowing outside the house. At this time, be careful when going in and out of the iron gate, your hand may hit the electric. After repeatedly encountering such a situation, you can take the following measures to avoid electric shock:
When touching the iron door, do not directly touch the iron door directly with your hand. Instead, use your hand to grasp a large number of keys in your pocket (usually this will not be shocked). Then, use the tip of a key to touch the iron door. In this way, the electricity on the body will be released and there will be no electric shock.
Principle: The pain of discharge on the hand is due to the high-voltage discharge. Because of the extremely small contact between the hand and the iron door during the discharge, an instantaneous high voltage is generated. If you take out the key in your pocket, first hold the key in a large area (a bunch of keys can't pass away any charge and there is no electric shock at this time), then use the tip of a key to touch the large conductor. The point of contact for the discharge is not a point on the skin of the hand, but the tip of the key, so the hand does not feel pain (maybe the key will!----if it is painful).
2. Electric shock often occurs when you take a taxi. Mainly due to the static accumulation of body and seat friction when getting off the car, and when the door is closed after getting off the vehicle, the hand suddenly hits the iron door and is shocked.
When this happens often, it is best to pay attention: when getting off the vehicle, that is, when the body and the seat are rubbed, the metal door frame is hand-held in advance, and the static electricity of the body can be drained at any time when friction generates static electricity, without When I get off the bus, I suddenly discharge when I touch the iron door.
