Description

technical field

[0001] The invention relates to a shoe, in particular to a step voltage alarm shoe. Background technique

[0002] Step voltage is the voltage generated between the limbs of people or animals passing near the grounding point after the electrical equipment is grounded. This voltage can cause electric shock accidents. Step voltage often appears near the fault grounding point of electrical equipment and where the power transmission and distribution line breaks and lands. In addition, there is also a step voltage near the ground electrode of the lightning rod during a lightning strike. Usually, there is a danger of step voltage electric shock within 20 meters of these fault points. Contents of the invention

[0003] The purpose of the present invention is to provide a step voltage warning shoe, which can send out a warning sound in advance when a person enters the above-mentioned range, so as to avoid personal injury and death accidents.

[0004] To achieve ...
