Embodiment Construction

[0010] like figure 1 As shown, the step voltage warning shoes of the present invention comprise a sole 1 and an upper 5 of a shoe, the sole 1 is an insulating sole, and a step voltage warning device is provided on the sole 1.

[0011] The step voltage alarm device includes a measuring probe 4 arranged at the bottom of the sole, and the measuring probe 4 is connected with the measuring alarm circuit 2 through a wire 3 . It should be noted that there are at least two measuring probes 4 , that is, there may be only two, or three or four. The measuring probes 4 are at a certain interval in the sole, and the interval can be set according to the density of isobars in the actual high pressure area.

[0012] The present invention passes the voltage on the ground into the voltage comparator through the measuring probe arranged at the bottom of the sole, and the voltage comparator A is an LM393 comparator, such as figure 2 As shown, Ur is the set voltage threshold, Uin is the voltage...

Abstract

The invention relates to step voltage alarm shoes. Each shoe comprises a sole and an upper, wherein the sole is insulated and is provided with a step voltage alarm device. The step voltage alarm shoes applied to the personnel of a power system as well as the common electricians can remind users whether the ground is electrified and whether the step voltage is dangerous. The step voltage alarm shoes can not only protect the safety of the users, but also facilitate the timely discovery of a grounding phenomenon of the system so as to take timely measures to avoid threats to the system security.

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 ...
