ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En Ia actualidad los sistemas de tierras para telecomunicaciones, se conforman por las barras de puesta a tierra convencionales, las cuales se podrían detallar como: Barras de cobre 100% macizo, de 20 pulgadas de largo, de 4 pulgadas de ancho y con un espesor de 1A de pulgada, con ocho pares de barrenos, todos de 3/8 de pulgadas de diámetro, con una separación de 2 pulgadas, los cuales tienen Ia función de aterrizar diferentes equipos y/o gabinetes, y dos barrenos laterales de 9/16 pulgadas de diámetro, que se emplean para fijar Ia barra. (Rg.At present, the ground systems for telecommunications are made up of conventional grounding bars, which could be detailed as: 100% solid copper bars, 20 inches long, 4 inches wide and with a thickness 1 A inch, with eight pairs of holes, all 3/8 inches 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. (Rg.
Estas barras de puesta a tierra de cobre, están en muchas ocasiones expuestos a Ia intemperie y por Io tanto, resultan atractivas para Ia delincuencia, pues además son fáciles de sustraer de las radio bases o instalaciones de telecomunicaciones.These copper grounding bars are often exposed to the weather and therefore are attractive to crime, because they are also easy to remove from radio bases or telecommunications facilities.
Como puede vislumbrarse, Ia actual barra de puesta a tierra, resulta muy costosa ya que su principal componente Io es el cobre, el cual en los mercados internacionales ha tenido un incremento sustancial, pero más costoso resulta aún, con su robo a gran escala y con los daños que se puede ocasionar a los equipos de telecomunicaciones en las radio bases o centrales, en el lapso que queda desprotegida el área con motivo de su robo, es decir durante el lapso de tiempo que implica Ia nueva instalación de Ia barra.As can be seen, the current grounding bar is very expensive since its main component is copper, which in the international markets has had a substantial increase, but it is 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 centrals, in the period that the area is left unprotected due to its theft, that is to say during the period of time that implies the new installation of the bar.
Con Ia finalidad de reducir el robo, se pensó en el desarrollo de Ia presente barra, que se pretende proteger por medio de Ia presente solicitud, pues se trata de un dispositivo, que no usa cobre, sus dimensiones se ajustan de forma precisa a las necesidades de conexión, sin mencionar que su conformación requiere de menos piezas y como sistema, es igual de eficiente que el eléctricamente usado actualmente. DESCRIPC1ON DE LA INVENCIÓNWith the purpose of reducing 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 as efficient as the one currently used. DESCRIPTION OF THE INVENTION

La figura 2 es una perspectiva convencional (isométrica) de Ia barra.Figure 2 is a conventional (isometric) view of the bar.
La figura 3 es una perspectiva lateral de Ia barra, (corte lateral)Figure 3 is a side perspective of the bar, (side section)
La figura 4 es una perspectiva superior de Ia barra.Figure 4 is a top perspective of the bar.
La figura 5 es una perspectiva frontal de Ia barra.Figure 5 is a front perspective view of the bar.
La figura 6 es una perspectiva isométrica armada de Ia barra.Figure 6 is an isometric perspective of the bar.
Con referencia a dichas figuras, esta barra cuenta en su parte frontal con ocho barrenos machoeleados de 1/2 pulgada, con una separación horizontal de 29.43 mm y de 40.04 mm verticalmente entre sus centros (No. 4), introduciéndose en cada uno de estos barrenos, un tornillo opresor hallen de acero inoxidable de V2 pulgada por 3/8 de pulgada de largo (No. 5), cuya finalidad es sujetar los conductores de puesta a tierra. En su parte posterior cuenta con tres correderas de cola de milano, una con salida en su parte superior y dos con entrada en Ia parte inferior (No. 3), en donde se insertaran las tiras trapezoidales, las cuales a su vez servirán para el ensamblaje vertical de más barras o bien para su sujeción a muro (No. 2). La barra cuenta en su parte superior con cuatro orificios transversales (No. 6), a través de los cuales se introducirán los conductores, siendo el caso de que el orificio transversal primero de izquierda a derecha, contara con una cubierta de acero inoxidable, evitando con ello el par galvánico (No. 1 1 ), además de que dicho orificios contara con un tapón aislador, diseñado especialmente para evitar Ia introducción de agua y/o de cualquier otro agente externo (No. 10). Por otra parte, Ia barra cuenta en sus extremidades laterales, por canales (correderas) de ensamblaje izquierdo y derecho (macho es igual al izquierdo y Ia hembra es igual al derecho), con un relieve (macho) y una profundidad (hembra) ambas de 5.08mm por un ancho de 5/8 pulgadas (No. 1 ), y las cuales en caso de no ser empleadas para ensamblaje de mas barras, serán cubiertas por un aislador cada una de ellas (No. 8), atornillándose por dos tornillos de opresión de VA de diámetro. (No. 9)With reference to these figures, this bar has on its front part eight eight 1/2 inch male holes, with a horizontal separation of 29.43 mm and 40.04 mm vertically between its centers (No. 4), being introduced in each of these holes, an oppressor screw made of stainless steel V2 inch 3/8 inch long (No. 5), whose purpose is to hold the grounding conductors. In its back it has three dovetail slides, one with an exit in its upper part and two with an entrance in the lower part (No. 3), where the trapezoidal strips will be inserted, which in turn will serve for vertical assembly of more bars or for wall mounting (No. 2). The bar has in its upper part with four transverse holes (No. 6), through which the conductors will be introduced, being the case that the first transverse hole from left to right, has a stainless steel cover, avoiding with this, the galvanic pair (No. 1 1), in addition to said holes having an insulating plug, specially designed to prevent the introduction of water and / or any other external agent (No. 10). On the other hand, the bar has in its lateral extremities, by channels (sliding) of left and right assembly (male is equal to the left and the female is equal to the right), with a relief (male) and a depth (female) both 5.08mm by a width of 5/8 inches (No. 1), and which if not used to assemble more bars, will be covered by an insulator each (No. 8), screwed by two VA oppression screws in diameter. (No. 9)
La construcción de Ia barra, se basa en una sola pieza de aluminio ό acero galvanizado, según se aprecia de las figuras 2 y 3, contando con un largo de 142.76 mm, por un ancho 76.37mm, y un espesor de 25.54mm, las cuales se obtiene después de llevar a cabo los cortes y perforaciones a través de fresadora y otros instrumentos.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 76.37mm, and a thickness of 25.54mm, which is obtained after carrying out the cuts and perforations through milling machine and other instruments.
La eficiencia en el trabajo de Ia barra reside en Ia flexibilidad para aumentar Ia cantidad de conexiones a tierra que vienen de diferentes equipos o bastidores, así como Ia nula introducción de agua por escurrimiento, así como de agentes externos como Ia corrosión y Ia oxidación, provocados por el medio ambiente, además de que por estar manufacturado en un material idóneo tal, como el aluminio ó acero galvanizado, se reducen sus costos de producción y minimiza notablemente su robo.The work efficiency of the bar resides in the flexibility to increase the amount of ground connections that come 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, its production costs are reduced and its robbery minimizes significantly.
La barra en cuestión trabaja de Ia siguiente manera: Al bajar a dicha barra todos y cada uno de los conductores de los diferentes equipos y bastidores eléctricos, el mismo se encarga de concentrar e igualar Ia diferencia de potencial, para finalmente canalizarla y descargarla a tierra.The bar in question works as follows: By lowering each and every one of the conductors of the different equipment and electrical racks down to the bar, it is responsible for concentrating and equalizing the potential difference, to finally channel it and discharge it to ground. .
El diseño y el material de Ia barra constituyen, en gran parte, Io novedoso de ésta, ya que en primer lugar, sus dimensiones se ajustan a las necesidades del usuario, toda vez que en una primera instancia pueden cubrir desde una y hasta un número indefinido de puestas a tierra, ya que como ya se ha citado, sus partes laterales extremas, y sus tiras trapezoidales permiten el ensamblaje de otras barras. - A -The design and material of the bar constitute, in large part, the novelty of it, since in the first place, its dimensions adjust to the needs of the user, since in the first instance they can cover from one to a number indefinite grounding, as already mentioned, its extreme side parts, and trapezoidal strips allow the assembly of other bars. - TO -
Continuαndo con Ia funcionalidad y/o operatividad que representan el ensamblaje en sus extremidades laterales (macho y hembra), y sus superiores e inferiores a través de sus tiras trapezoidales, dicha barra no sólo se puede agrandar y/o ampliar, sino que además ajusfar a espacios reducidos, de difícil acceso o bien hasta a una colocación de forma vertical.Continuing with the functionality and / or operability that represent the assembly in its lateral extremities (male and female), and its upper and lower through its trapezoidal strips, said bar can not only be enlarged and / or extended, but also adjusted to small spaces, difficult to access or even to a vertical placement.
Otro de los beneficios de este novedoso artefacto, es el que por los materiales de que se conforma, se minimiza su corrosión y oxidación, ante su exposición al medio ambiente, con Io cual se optimiza Ia conductividad de Ia energía.Another of the benefits of this new device, is that by the materials of which it is formed, its corrosion and oxidation is minimized, before its exposure to the environment, with which the conductivity of the energy is optimized.
Por otra parte, este novedoso artefacto, posee Ia cualidad de tener una conexión más rápida, ya que no se requiere de herramienta especializada (terminales mecánicas o de compresión, fundas aislantes), pues el tornillo de opresión de acero inoxidable con cabeza hallen, permite una sencilla y rápida instalación.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 sleeves), because the stainless steel oppression screw with head find, allows A simple and quick installation.
Finalmente, al ser de aluminio ό acero galvanizado, reducirá de forma sustancial su costo en el mercado, toda vez que el metal empleado es de menor costo que el cobre, Io cual a su vez trae como consecuencia, que dicho artefacto no resulte atractivo para Ia delincuencia, pues este artefacto sustituye el 100% del cobre de que se conformaba Ia barra convencional.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 the fact that said device is not attractive for The crime, because this device replaces 100% of the copper that formed the conventional bar.
La barra por sus materiales de conformación que pueden ser de aluminio o acero galvanizado, tienen valores definidos para Ia conducción eléctrica y choque térmico, esta información se concentra en Ia ecuación de Onderdonk y es altamente empleada en Ia industria eléctrica como parámetros de diseño de piezas destinadas a conducir corriente. Estos valores determinan si una pieza de metal es capaz de conducir un valor indicado de corriente eléctrica en un tiempo establecido. Por tanto y en base a los datos estadísticos por CIGRE (Conferencia Internacional de Sistemas Eléctricas en Alto voltaje) Francia ha definido valores y tiempos de falla para las descargas atmosféricas o rayo. Estos rangos son Io que hemos empleado para valorar las condiciones a las que dicha barra pudiera estar expuesta, pues en muchas ocasiones estará a Ia intemperie y por tanto poder ser objeto de un impacto directo de rayo. Dicho Io anterior establecemos que:The bar for its conformation materials that can be made of aluminum or galvanized steel, have defined values for electric 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 the statistical data by CIGRE (International Conference of 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 occasions it will be outdoors and therefore can be subject to a direct impact of lightning. Said the previous we establish that:
En un 957o de los impactos de rayos tenemos un valor de 15 kilo amperes en un tiempo de 0.000001 segundos, se requiere una sección transversal de aluminio de 3.31 mm2, y para el caso de acero se requiere una sección transversal de 1 1.15 mm2.In a 957th of lightning strikes we have a value of 15 kilo amps in a time of 0.000001 seconds, an aluminum cross section of 3.31 mm2 is required, and for the case of steel a cross section of 1 1.15 mm2 is required.
En un 50% de los impactos de rayos tenemos un valor de 30 kilo amperes en un tiempo de 0.000075 segundos, se requiere una sección transversal de aluminio de 12.84 mm2, y para el caso de acero se requiere una sección transversal de 35.27 mm2.In 50% of the lightning impacts we have a value of 30 kilo amps in a time of 0.000075 seconds, a 12.84 mm2 aluminum cross section is required, and for the case of steel a 35.27 mm2 cross section is required.
En un 5% de los impactos de rayos tenemos un valor de 80 kilo amperes en un tiempo de 0.0002 segundos, se requiere una sección transversal de aluminio de 55.90 mm2, y para el caso de acero se requiere una sección transversal de 153.60 mm2.In 5% of lightning strikes we have a value of 80 kilo amps 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.
Por tanto podemos establecer que para todos los casos antes mencionados el diseño de Ia barra en aluminio o en acero galvanizado tiene una sección transversal de 3000 mm2, y cumple y sobre pasa con Ia sección transversal requerida, sin presentar daño en su estructura mecánica. 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 complies with the required cross section, without presenting damage to its mechanical structure.
