Description

Street lamp electric leakage alarm set {Street lamp electric leakage alarm set}

The present invention relates to a street light leakage alarm device for detecting in real time the leakage of the street lamp in rainy weather, more specifically, by using a current leakage current leakage to the ground through the street lamp, the street light leakage alarm device By supplying power to the lamp, the LED lamp and the piezo buzzer of the street light leakage warning device without a separate power supply is operated, and relates to a street light leakage warning device that allows pedestrians in rainy weather to recognize whether the street light is leaking.

In general, street lamps installed on the road are structures that are installed to minimize traffic accidents at night and have only a function of turning on and off. There are many reasons for the leakage of these street lights.

Underground lines that connect street lamps to each other may be destroyed during water and sewage construction, and the sockets of street lamps may be corroded, causing a short circuit in the column. As a safety device for streetlights, the circuit breaker is only about a ground fault circuit breaker.If the ground fault circuit breaker does not operate in rainy weather or the ground fault is maintained even if the ground fault circuit breaker operates due to other factors, it prevents electric shocks around the street lamp from pedestrians. I can't do it. In order to solve this problem, a method of wrapping a circumference of a street lamp with an insulator such as rubber or plastic has been proposed and used.

However, the method of wrapping the street lamps with insulators not only damages the aesthetics of the street lamps, but the short circuit caused by rainwater flowing through the street lamps due to the heavy rains in the summer rainy season has insufficient effect, and it recognizes the danger of electric shock of pedestrians. The situation is not taken.

In order to solve this problem, conventionally, the ground acts as a ground for sucking electricity. Accordingly, leakage current leaking from underground lines does not lead to human damage, and only electricity flowing from street lamps causes great damage to the human body. It is proposed to provide a technology to notify the public officials in charge of automatic detection of street light shortages during the daytime when the street lights are off to the PDA, etc. to check the location and the amount of leakage of the street light and to maintain it before leaving work. It became. Generally, the above-described technology maintains the streetlights by judging whether the streetlights are leaked during the day, and prevents electric shocks in advance.However, real-time occurrences of the day and night are caused by rainwater such as electric shock accidents occurring before the maintenance of the streetlights and the summer rainy season. There is a problem that can not cope with an electric shock accident caused by a short circuit of the lamp.

An object of the present invention for solving the above-mentioned problems is to provide a streetlight short-circuit warning device that can prevent a streetlight short circuit electric shock accident in advance by paying attention to whether the streetlight pedestrian is installed on the road.

Another object of the present invention is to prevent secondary leakage caused by the self-leakage of the street light leakage alarm device that is operated by the power supply of the street lamp, leakage due to the leakage of the street lamp without a separate power supply It is to provide a streetlight short circuit alarm device that can operate using the current.

A feature of the present invention for achieving the stated technical object relates to a streetlight short circuit alarm device, which enables a pedestrian to recognize a short circuit condition of a street light when rainy weather conditions of the street light,

 Rubber housing; A ground conductor portion; It consists of metal fasteners.

The rubber housing of the street light leakage alarm device is connected to a street light having a street light leakage current input terminal, and a ground current through a led lamp and a piezo buzzer receiving the ground current of the street light leakage current input terminal flows to the ground by a ground conductor. Thus, the streetlight short circuit alarm device operates without a separate power supply device.

The ground conductor part of the street light short circuit warning device is a device for connecting between the street light and the earth, and is connected to the rubber housing of the street light short circuit warning device to allow a short circuit current of the street light to flow to the ground during rainy weather. Let the device work.

The metal fastener part of the street light short circuit warning device is a metallic material band which fastens the rubber housing part of the street light short circuit alarm device and the ground conductor part of the street light short circuit warning device to the street lamp, so that the street light short circuit alarm device is fixed to the street lamp.

Types of electric shock accidents include contact between both ends of the AC live wire; AC liveliness and earth contact; It is caused by contact between the ground and the ground due to short circuit of AC live wire.

In the form of a street light leakage accident, when a short circuit occurs in a street light due to a poor insulation of a wire or a lamp socket of a street lamp, a human body acts as a conductor between the street lamp and the ground, and causes a current to flow between the street lamp and the ground.

In the dry ground of the street lamp, the current leakage does not flow due to the high resistance between the street lamp and the ground.However, in the rainy season, such as in the rainy season, the water is very conductive and the surface of the ground makes the street lamp come into contact with the ground fault lamp. The leakage current of the current flows through the human body to the earth will cause an electric shock.

  As described above, the electric shock accident due to the leakage of the street light is focused on the occurrence of when the surface of the earth is wet with water, to provide a street light leakage alarm device that operates when the leakage current of the street light flows to the ground in rainy weather. .

Street light leakage alarm device according to the present invention having the above-described configuration through the LED lamp and the piezo buzzer short-circuit alarm whether or not the short-circuit of the street lamp in rainy weather, so that the pedestrian can recognize the short-circuit of the street lamp, It is effective in preventing electric shock.

In addition, the street light leakage warning device according to the present invention can be installed in a place such as a crosswalk signal light, there is an effect that can also prevent an electric shock accident due to a traffic light leakage.
