Abstract
The present invention refers to an improved bar best know as 2G9-connection Ground Bar (EP-BT2G9C), which concentrates all and each of the grounded conductors pertaining to different equipments and electric housings in order to equalise the potential difference and finally lead and discharge it to the ground mesh. The purpose of the present invention is to provide a type of bar totally different from those currently available on the market since it has a multifunctional construction, which main characteristic is that it reduces short, half and long term costs; on the one hand, the reproduction cost of the bar is low as the raw material thereof is cheaper than copper, on the second hand, said raw material is not as attractive as copper is to thieves, thereby providing excellent results and reducing risks as the joints are not weather exposed but located at the inner portion of the bar, which has a stainless steel cover for preventing external agents from entering.
Description
IMPROVEMENTS IN GROUNDING BAR
BACKGROUND OF THE INVENTION
At present, land systems for telecommunications are made up of conventional grounding rods, which could be detailed as: 100% solid copper bars, 24 inches long, 2 inches wide and with a thickness of 3/8 inch, with 9 holes, all 3/8 inch in diameter, through which the equipment is landed to the ground mesh, and two 9/16 inch diameter side holes, which are used to fix the ba. (Fig. 1)
These copper grounding rods are often exposed to the weather and therefore are attractive for crime, because they are easy to steal from radio bases or telecommunications facilities.
As can be glimpsed, the current grounding bar is very expensive since its main component is copper, which in international markets has had a substantial increase, but even more expensive, with its large-scale theft and with the damages that can be caused to the telecommunications equipment in the radio bases or power stations, in the time that the area is left unprotected due to theft, that is to say during the lapse of time that implies the new installation of the bar.
In order to reduce theft, the development of the present bar was considered, which is intended to be protected by means of the present application, since it is a device, which does not use copper, its dimensions are precisely adjusted to the connection needs, not to mention that its conformation requires fewer parts and as a system, it is just as efficient as the one currently used electrically.
DESCRIPTION OF THE INVENTION
The characteristic details of this novel 2G Earth Bar 9 connections (EP-BT2G9C), are clearly shown in the following description and the accompanying drawings, which have reference signs to indicate the parts and figures shown.
Figure 2 is a conventional (isometric) perspective exploited of the bar.
Figure 3 is a side perspective of the bar, (side cut)
Figure 4 is a front perspective of the bar.
Figure 5 is a top perspective of the bar.
Figure 6 is an armed front isometric perspective of the bar.
With reference to said figures, this bar has on its front part 18 holes 3/8 of an inch, with a horizontal separation of 58.20 mm and of 25.00 mm vertically between its centers (No. 3), being introduced in each of These holes, an oppressor screw, have stainless steel 3/8 inch by 3/8 inch long, which is intended to hold the grounding conductors (No. 4). On the back it has two dovetail sliders (No. 1), where the brackets will be inserted for fixing to a metal structure or wall. The bar has in its upper part nine transverse holes (No. 2), through which the grounding conductors will be introduced, being the case that the transverse hole first from left to right, has a cover of stainless steel, thus avoiding the galvanic pair (No. or), in addition to these holes have an insulating plug, designed especially to prevent the introduction of water and / or any other agent within them. (No. 5)
The construction of the bar is based on a single piece of aluminum or Galvanized Steel, as shown in figures 2 and 3, with a length of 500.00 mm, a width of 50.75 mm and a thickness of 25.04 mm, which is obtained after carrying out the cuts and perforations through a milling machine and other instruments.
The working efficiency of the bar lies in that being manufactured in a suitable material such as aluminum or galvanized steel, its production costs are reduced and its theft is significantly minimized, as well as the null introduction of water by runoff and external agents such as corrosion and oxidation, caused by the environment.
The bar in question works in the following way: By lowering each and every one of the grounding conductors to said bar, it is responsible for concentrating and equalizing the potential difference, in order to finally channel it and discharge it to the earth mesh .
The design and material of the bar are, to a large extent, the novelty of this, since in the first place, its dimensions are adjusted to the needs of the user, since it can cover from one and up to nine earthing points.
Another of the benefits of this novel device, is that by the materials that are formed, its corrosion and oxidation is minimized, before its exposure to the environment, which optimizes the conductivity of the energy.
On the other hand, this new device has the quality of having a faster connection, since it does not require a specialized tool (mechanical or compression terminals, insulating sheaths), since the stainless steel oppression screw with head seal, allows a simple and quick installation.
Finally, since it is made of aluminum or galvanized steel, it will substantially reduce its cost in the market, since the metal used is of lower cost than copper, which in turn results in said device not being attractive for delinquency, because this device replaces 100% of the copper that the conventional bar was made of.
The bar for its shaping materials that can be made of aluminum or galvanized steel, have defined values for electrical conduction and thermal shock, this information is concentrated in the Onderdonk equation and is highly used in the electrical industry as part design parameters intended to conduct electric current. These values determine if a piece of metal is capable of conducting an indicated value of electric current in a set time. Therefore, based on statistical data by CIGRE (International Conference on High Voltage Electrical Systems), France has defined values and failure times for atmospheric discharges or lightning. These ranges are what we have used to assess the conditions to which said bar could be exposed, since in many cases it will be outdoors and therefore be able to be the object of a direct lightning strike.
Having said the foregoing, we establish that:
In 95% of lightning strikes we have a value of 15 kilo amperes in a time of 0.000001 seconds, an aluminum cross section of 3.31 mm2 is required, and in the case of steel a cross section of 1 1 .15 is required. mm2
In 50% of the lightning strikes we have a value of 30 kilo amperes in a time of 0.000075 seconds, an aluminum cross section of 12.84 mm2 is required, and for the case of steel a cross section of 35.27 mm2 is required.
In 5% of the lightning strikes we have a value of 80 kilo amperes in a time of 0.0002 seconds, an aluminum cross section of 55.90 mm2 is required, and for the case of steel a cross section of 153.60 mm2 is required.
Therefore we can establish that for all the aforementioned cases the design of the bar in aluminum or galvanized steel has a cross section of 6000 mm2, and meets and passes with the required cross section, without presenting damage to its mechanical structure.
