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
The present invention relates to a kind of footwear, be specifically related to a kind of step voltage warning footwear.
Background technology
After step voltage is electrical equipment ground connection, the voltage that between the limbs of near the people of the process earth point or animal, produces.This voltage can produce electric shock accidents.Step voltage often appears near the electrical equipment malfunction earth point and the electric line broken string lands the place.In addition, also exist step voltage near the lightning rod earthing pole during thunderbolt.Usually, the danger that all exists step voltage to get an electric shock in the 20 meters scopes in these trouble points.
Summary of the invention
The object of the present invention is to provide a kind of step voltage warning footwear, the sound equipment that can give a warning in advance in personnel enter above-mentioned scope is avoided human casualty accident.
For achieving the above object, the technical solution used in the present invention is as follows:
Step voltage warning footwear of the present invention comprise sole and upper of a shoe, at the bottom of sole is insulated shoes, are provided with the step voltage warning device on sole.
Described step voltage warning device comprises the measuring probe that is arranged on the sole bottom, and measuring probe is connected with the measurement warning circuit by lead.
Step voltage warning footwear of the present invention are applied to vast power system employee, also can be used for common electrician.Can remind whether electricity is arranged on the user of service ground, whether step voltage dangerous, can protect user of service's safety well, helps discovery system in time again and have grounding phenomenon, avoids threatening security of system so that in time handle.Realize safety utilization of electric power, avoid the purpose of human casualty accident.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of warning circuit among the present invention.
The specific embodiment
As shown in Figure 1, step voltage warning footwear of the present invention comprise sole 1 and upper of a shoe 5, at the bottom of sole 1 is insulated shoes, are provided with the step voltage warning device on sole 1.
Described step voltage warning device comprises the measuring probe 4 that is arranged on the sole bottom, and measuring probe 4 is connected with measurement warning circuit 2 by lead 3.Need to prove that measuring probe 4 is at least two, can only be two promptly, also can be three or four.At a distance of certain intervals, can set according to the isobar dense degree in actual high-voltage zone by this interval in sole for measuring probe 4.
The present invention is imported ground voltage into voltage comparator by the measuring probe that is arranged on the sole bottom, voltage comparator A is the LM393 comparator, as shown in Figure 2, the voltage threshold of Ur for setting, Uin is two voltage differences between the measuring probe 4, when Uin＞Ur, and the Vo output HIGH voltage, be triode T1 conducting, alarm equipment alarm.Like this, when the people enters into the higher-pressure region, if the electromotive force between the measuring probe 4 in the middle of per step is higher than the value of setting, illustrate that promptly this zone is very dangerous, alarm the staff enhance your vigilance.
Claims (2)
