The present invention relates to a grounding rod structure for preventing electric shock accidents or damage and malfunction of electronic equipment used in an electric use facility, and more specifically, grounding noise and vibration even when installed on a rock or the like when installing the grounding rod in the ground. The present invention relates to a drill blade-shaped ground rod structure that can reduce construction costs and reduce construction costs.
In electrical installations, grounding is the most basic safety device. Inappropriate grounding facilities in electrical installations may cause electric shocks, damage to electronic equipment, and malfunctions. Therefore, it is essential to maintain a complete grounding facility for preventing accidents, protecting expensive equipment, and preventing malfunctions.
According to the guidelines of the Korea Occupational Safety and Health Agency, when installing in places where people may be in contact, such as Jeonju, the grounding electrode should be buried at a depth of 75cm or below. In addition, the specified ground resistance of the pole in which the transformer is installed shall be 25 Ω or less in accordance with the electrical equipment technical standards.
In general, the grounding resistance of the ground rod is easier to secure the ground resistance as deeply buried in the ground as possible, and when it meets a large and large rock in the ground, it cannot penetrate the rock, which is a considerable difficulty in securing the specified ground resistance suitable for the electrical equipment technical standards. I have been.
Accordingly, a ground rod in which a hot dip galvanized ground rod is constructed by a deep perforation method has been proposed, that is, FIG. 3 is a schematic view showing a structure of a conventional multi-stage seam ground rod. The ground rod configuration is connected to the
However, in the structure of the conventional multi-stage grounding rod as described above, if a large and large rock is encountered in the ground in the middle of the grounding of the
As a result, noise is generated in the process of attempting to crush the rock, which inevitably causes noise pollution to the residents in the city center or near construction sites. In addition, noise and vibration problems, such as cracks caused by vibrations in buildings or walls, and complaints such as compensation, cause the residents to hate electrical installations and oppose the installation of power facilities near buildings. Complaints have been raised, and the structure of the conventional multi-stage grounding rods as described above is not parallel to the rock if it meets a large and large rock in the ground during the burying of the
An object of the present invention is to solve the conventional problems as described above, and meet the large and large rock in the ground in the ground during the burying of the multi-stage grounding rod for Bream using the Breca can not fracture the rock and electrical equipment technical standards In addition to acting as a significant difficulty in securing a proper grounding resistance suitable for the use, as well as the shape of the drill blade shape of the body of the multi-stage grounding rod for preventing severe noise and vibration when the rock continues to be hit by Breca. The drill rod is a low noise using an electric drill (not shown) instead of the blow method using Breca, and it is a screw or coupling-type drill blade that makes it easy to secure the specified ground resistance by drilling even if it meets rocks in the ground. To provide a shaped ground rod structure.
As a means for achieving the above object, the configuration of the present invention, the processing ground wire is installed to protect the equipment, such as transmission and distribution lines and transformers from lightning, the ground wire extending from the fatigue stage to the ground, and the end of the ground wire It is embedded in the ground by a screw or coupling coupling screw or coupling-type drill blade ground rod to extend the length, and a ground wire connecting sleeve for connecting the lead terminal and the ground wire of the drill blade ground rod In the screw or coupling-type drill blade ground rod, the screw or coupling-type drill blade-shaped ground rod is processed by drilling the body into the shape of the drill blade to drill the rock by using a drill even if the rock meets the ground while installing the ground rod in the ground It is characterized in that the grounding work is very easy.
Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
Figure 1 is a schematic view showing the structure of the drill rod-shaped grounding rod according to the present invention, Figure 2 is a partial cross-sectional configuration showing the main portion of the present invention separated.
The present invention extends to a processing ground line or an arrester installed to protect devices such as transmission and distribution lines and transformers from lightning strikes, and connects the
In addition, the
On the other hand, Figure 2 is a view showing the separation of the
In addition, the
As described in the above embodiment, the present invention, unlike the conventional body of the multi-stage shim ground rod and lead terminal is circular, by making a circular body to be processed into a drill blade shape, as in the conventional hammer or hydraulic Breca during the type When a large rock is widely distributed on the ground, it is no longer possible to be struck. Therefore, the grounding work is completed without securing the statutory resistance value according to the Electric Equipment Technology Standard Ordinance. Although the resistance value is secured, if a drill-type ground rod is used, the grounding work is possible until the desired specified resistance is obtained by drilling using a drill even if it meets a rock, and the grounding work is much easier than the current one, and prevents additional parallel work. Thus, the ground construction cost is greatly reduced.
In addition, the present invention has the effect that noise is generated in the process of attempting to break the rock when encountering the rock as in the past, inevitably causes noise pollution inhabitants in the downtown or near construction sites.
In addition, the present invention can solve the problem of civil complaints caused by the damage caused by the vibration when the rock breaks into the Breca due to the vibration, and environmentally friendly grounding is possible to improve the quality of life of the people There is an effect that can be greatly contributed to.
