Abstract
The present invention refers to an improved bar best know as multi-articulated bar, 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, 20 inches long, 4 inches wide and with a thickness ¼ inch, with eight pairs of holes, all 3/8 inch in diameter, with a separation of 2 inches, which have the function of landing different equipment and / or cabinets, and two side holes of 9/16 inches in diameter, which are used to fix the bar. (Fig. 1)
These copper grounding rods are often exposed to the weather and therefore are attractive for crime, because they are also 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 its 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 Articulated Bar of 4 Connections with 2 Upper Slides (EP-BT2GA4CMI2CS), are clearly shown in the following description and in the accompanying drawings, which have reference signs to indicate the parts and the figures shown.
Figure 2 is a conventional (somometric) perspective of the bar.
Figure 3 is a side perspective of the bar, (side cut)
Figure 4 is a top perspective of the bar.
Figure 5 is a front perspective of the bar.
Figure 6 is an isometric armed perspective of the bar
With reference to said figures, this bar has on its front part eight male-hole holes of 1/2 inch, with a horizontal separation of 29.43 mm and of 40.04 mm vertically between its centers (No. 4), being introduced in each of these drill holes, an oppressive screw have ½ inch stainless steel by 3/8 inches long, which purpose is to hold the grounding conductors (No. 5). On the back it has three dovetail slides (No. 3), two with an exit on the upper part and one with an entrance on the lower part, where the trapezoidal strips will be inserted, which in turn will serve for the vertical assembly of more bars or for wall attachment (No. 2). The bar has in its upper part four transverse holes (No. 6), through which the conductors will be introduced, being the case that the transverse hole first from left to right, had a stainless steel cover, avoiding with it the galvanic pair (No. 1 1), in addition to that said orifices will count
with an insulating cap, specially designed to prevent the introduction of water and / or any other agent. (No. 10) On the other hand, the bar has in its lateral extremities, by channels (sliding) left and right assembly (male is equal to the left and female is equal to the right), with a relief (male) and a depth (female) both of 5.08 mm by a width of 5/8 inches (No. 1), and which if not used for assembly of more bars, will be covered by an insulator each one of them (No. 8) ), screwed by two oppression screws of ¼ inch diameter. (No. 9).
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 142.76 mm, a width of 76.37 mm, and a thickness of 25.54 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 the flexibility to increase the number of ground connections coming from different equipment or racks, as well as the null introduction of water by runoff, as well as external agents such as corrosion and oxidation, caused by the environment, in addition to being manufactured in a suitable material such as aluminum or galvanized steel, reduce their production costs and significantly minimizes theft.
The bar in question works in the following way: When going down to this bar each and every one of the drivers of the different equipment and electrical racks, it is in charge of concentrating and equalizing the potential difference, to finally channel it and discharge it to land. .
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 in a first instance they can cover from one and up to a number
Ndefinido of grounded, since as already mentioned, its extreme lateral parts, and trapezoidal strips allow the assembly of other bars.
Continuing with the functionality and / or operability that the assembly represents in its lateral extremities (male and female), and its superiors and inferiors through its trapezoidal strips, this bar can not only be enlarged and / or enlarged, but also adjust to small spaces, difficult to access or even to a vertical placement.
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 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 less expensive than copper, which in turn means that the device is not attractive to the public. 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 drive current. These values determine if a piece of metal is capable of conducting an indicated value of electric current in a set time. Therefore and based on statistical data by CIG E (Conference
International Electrical Systems in High Voltage) 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 many times 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 the 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 for the steel case 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 3000 mm2, and meets and passes with the required cross section, without presenting any damage to its mechanical structure.
