Electric shock generally refers to the human body touching the charged body, the damage caused by the current through the human body, the electric shock and the electric shock.
Electric shock refers to the current through the body, destroying the normal work of the heart, lungs and nervous system, which can be life-threatening. According to the way of human body electric shock and current through the human body, there are three cases of electric shock:
(1) Single-phase electric shock refers to the electric shock accident that the human body touches the single-phase charged body;
(2) Two-phase electric shock refers to the electric shock accident that the human body touches the two-phase charged body at the same time, which is very dangerous;
(3) Stepping voltage is electric shock. When the grounding current of the charged body flows into the ground, the current will drop voltage around the grounding point. The stepping voltage appears between the two feet at the grounding point. The electric shock accident caused by this is called striding. The voltage is electric shock.
Electrical injury refers to local damage caused by current thermal, chemical or mechanical effects.
The risk of electric shock is related to the magnitude of the current through the human body, the length of time, and the frequency of the current. A current of 100 mA flows through the human body and is fatal. AC at 40 to 60 Hz is more dangerous than current at other frequencies.
