Abstract
The utility model discloses a step voltage alarm device which consists of a signal alarm device, a bracket and earth electrodes and is characterized in that two earth electrodes are provided; the signal alarm device is connected between the two earth electrodes by a wire; a certain distance is reserved between the two earth electrodes; and when the two earth electrodes are simultaneously conducted with measured earth points, if a voltage exists between two measured earth points or the voltage exceeds a preset voltage constant value, the signal alarm device can actuate to send out an alarm signal to prompt people to pay attention to the step voltage. The step voltage alarm device can be used for timely reminding people of paying attention to prevention for the step voltage electric shock so as to ensure the safety.
Description
Technical field
The utility model relates to a kind of step voltage warning device, belongs to electronic technology field.
Background technology
Along with the development of economic society, electricity more and more becomes indispensable resource in people's production, the life.Yet, just because electricity omnipresent also increased the risk that people get an electric shock.Produce, in the life because people's mistakenly entering charged chamber, mistakenly entering into charged zone, and equipment leakage, circuit the step voltage electric shock accidents former thereby that cause such as land and happen occasionally, people's the security of the lives and property in serious threat.Take the method strick precaution step voltage electric shock risk of correct science imperative.
Power supply enterprise is in the power supply service process, because its staff often will touch step voltage, thereby, can play monitoring, preventive effect to step voltage, be directly connected to staff's life security.
Therefore, designing a kind of step voltage warning device, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of step voltage warning device.
The technical scheme in the invention for solving the technical problem is:
Step voltage warning device, by signalling alarm equipment, support and earthing pole form, it is characterized in that: very two of described ground connection, signalling alarm equipment is connected between two earthing poles by wire, keep certain distance between two earthing poles, when two earthing poles are connected with tested earth point simultaneously, surpass predefined voltage definite value (this voltage definite value is set according to the safe voltage limit value that human body can bear usually) such as have voltage or this voltage between two tested earth points, signalling alarm equipment can move, send alerting signal, the prompting people note step voltage.
Preferably, described support is insulation or nonisulated sole, and signalling alarm equipment, earthing pole embed in insulation or the nonisulated sole and earthing pole stretches out sole, two earthing poles by toe cap and heel, when people's walking or stop, directly contact with the earth, realize the monitoring, alarming effect.
The beneficial effects of the utility model have provided a kind of monitoring, alarming function of step voltage, in time remind people to note taking precautions against step voltage and get an electric shock, and ensure safety.
Description of drawings: Fig. 1 schematic diagram of the present utility model;
Fig. 2 the utility model step voltage warning device is implemented figure;
3 is that wire, 4 is at the bottom of the insulated shoes among the figure.
Embodiment
With reference to accompanying drawing 1.This step voltage warning device is made of earthing pole 1, connection wire, signalling alarm equipment, earthing pole 2 etc.Earthing pole 1 links to each other with signalling alarm equipment by connecting wire, and signalling alarm equipment links to each other with earthing pole 2 by connecting wire.Namely between earthing pole 1 and earthing pole 2, seal in signalling alarm equipment by connecting wire.When keeping certain distance between two earthing poles and connecting with two tested earth points simultaneously, surpass predefined voltage definite value (this voltage definite value is set according to the safe voltage limit value that human body can bear usually) such as have voltage or this voltage between two tested earth points, signalling alarm equipment can move, send alerting signal, the prompting people note step voltage.According to the difference of people's demand, the alerting signal that step voltage warning device sends can be the various types of signal such as sound, light, vibration, note.
With reference to accompanying drawing 2.Different according to demand, this step voltage warning device can embed in insulation or the nonisulated sole, by two earthing poles of toe cap and heel, when people's walking or stop, directly contacts with the earth, realizes accompanying drawing 1 described monitoring, alarming effect.In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection domain of the utility model requirement.
Claims (3)
1. step voltage warning device, formed by signalling alarm equipment, support and earthing pole, it is characterized in that: very two of described ground connection, signalling alarm equipment is connected between two earthing poles by wire, keeps at a distance between two earthing poles, when two earthing poles are connected with tested earth point simultaneously, surpass predefined voltage definite value such as have voltage or this voltage between two tested earth points, signalling alarm equipment can move, and sends alerting signal, and the prompting people note step voltage.
2. step voltage warning device according to claim 1, it is characterized in that: described support is insulation or nonisulated sole, signalling alarm equipment, earthing pole embed in insulation or the nonisulated sole and earthing pole stretches out sole, two earthing poles by toe cap and heel, when people's walking or stop, directly contact with the earth, realize the monitoring, alarming effect.
3. step voltage warning device according to claim 1 is characterized in that: the safe voltage limit that described predefined voltage definite value behaviour body can bear.
