Excuse me, what is the working principle of an electric shock protector of Hengxiang Safety Technology, which is "no leakage when immersed in water, no injury when electrocuted"?

The simple description of the principle is that the current of the leakage equipment reduces the safe current value of the human body through the equipment, so that the electric shock personnel will not have an accident due to electric shock. Because the leakage does not reach the tripping current value of the leakage protector, it will not trip. At present, this kind of equipment has not been widely used, which is easy to cause wrong judgment and wrong cognition of power users. After all, electronic equipment is not as intuitive as mechanical equipment, so this is the bottleneck of this product.

Explain the safe voltage current of human body: according to industry regulations, the safe voltage is not higher than 36V, the continuous contact with safe voltage is 24V, and the safe current is 10mA. The harm of electric shock to human body mainly depends on the current passing through human body and the length of electrifying time. The greater the current intensity, the greater the fatal danger; The longer it lasts, the more likely it is to die. The minimum current that can cause people to feel is called perceptual current, with AC of 1mA and DC of 5 mA. The maximum current that people can get rid of by themselves after getting an electric shock is called get rid of current, with AC of 10mA and DC of 50mA. The life-threatening current in a short time is called lethal current, which is 50mA. In the case of electric shock protection device, the allowable current of human body is generally 30mA.
