Description

Step voltage monitoring safety shoes

Technical Field

The utility model discloses a step voltage monitoring safety shoe belongs to safety product technical field.

Background

When the electrical equipment has a ground fault, the ground current is dispersed to the ground through the grounding body, and a distributed potential is formed on the ground. If a person walks around the grounding short-circuit point, the potential difference between two feet (the step of the person is generally considered to be 0.8 meter) is the step voltage. When the human body is subjected to the action of the step voltage, the human body is not directly contacted with the electrified conductor and does not have the arc discharge phenomenon, but the current is along the lower body of the human body; from one foot through the crotch to the other, forming a pathway with the ground. The foot feels numb first and then falls down when an electric shock occurs. When a higher step voltage is reached, the feet will cramp and fall on the ground. After a fall, the voltage applied to the body increases due to the large distance between the head and the foot, and the current of the electric shock increases accordingly, and it is also possible to change the path of the current through the body to pass through important organs of the body, such as from head to foot or from head to hand. Thus increasing the hazard of electric shock. After the human body falls to the ground, the voltage lasts for 2 seconds, and then the human body has fatal danger.

The prior utility model patent with publication number CN201820657141.4 discloses a public step voltage alarm device and shoes with alarm.
