Electricity in the subway<\/h2>\n\n

The \n energy companies in the cities in which the metro was installed \nwere not, at first, usually able to offer the energy \nnecessary to make it work. Therefore, it is normal that, at the beginning, \n this means of transport system has its own power station. \nelectricity, as was the case in our own Madrid, which, because of its \nright, he’s available to visit in the Pacific neighborhood. As \ncuriosity, to indicate that this not only came to supply the whole system, \nin moments of precariousness such as the Civil War. \nelectrical support to the entire city.<\/p>\n\n

With \n the passing of years and the improvement of the capacity of the \nthe network became supplied by them, since this process was not only \nbecame less expensive.<\/p>\n\n

However, there was a considerable problem: the incompatibility between currents. The meter needs direct current and the companies offer alternating current.<\/strong><\/p>\n\n

In order to find a solution to this problem, an energy transformation is needed, which, although it is now conceived in a simple way, has its work to do.<\/p>\n\n

Connectors and contacts Alfa\u00b4R in the metro<\/h3>\n\n

It is at this point that our connectors and contacts Alfa\u00b4R<\/a> \n are at stake, because this task of transformation requires the \nmanagement and modification of the electrical network for which the following is required \na network of substations and that, of course, is satisfied with quantity \nof products of this type and many others.<\/p>\n\n

These \n are interconnected via alternating current, reaching them, in the case of \nour country, 15,000 volts, through a red wiring that we see in the \nthe tunnels easily when we travel. In this way you get that, \nin the event of a substation failure, the others can give you \nsupport, thus forming a redundant system.<\/p>\n\n

In \n In any case, we have a medium-voltage energy that will stop at \na rectifier substation, which is responsible for stabilizing the \nvoltage as well as making the voltage lower to operate on line, \n of 600 or 1500 volts. It is also at this point that said \ncurrent changes from alternating to direct.<\/p>\n\n

Once again, we contribute our grain of sand with the installation of feeders<\/em><\/strong>, which are the ones that take that power supply to the laying cable of the meter<\/em>. Its section is variable, being chosen according to two parameters: Distance to travel and voltage. We also find here seccionadores <\/em><\/strong>, which allow the current to reach the train through the pantograph and thus feed the train’s equipment. <\/p>\n\n

Finally, \n know that commuter trains also function in the same way but with a different \nconversion of the energy to 3000 volts, which is the necessary one in the \nIberian tendido.<\/p>\n","protected":false},"excerpt":{"rendered":"

En muchas ocasiones, nuestros productos \nse relacionan con uni\u00f3n de piezas s\u00f3lidas, pensados para posibilitar el \nmontaje de maquinaria. Sin embargo, la funcionalidad principal se \nrelaciona con el tendido de cables y es de ello de lo que hablaremos hoy\n al contarte c\u00f3mo funciona el metro a nivel de tendido el\u00e9ctrico.<\/strong><\/p>\n\n\n\n

La electricidad en el metro<\/h2>\n\n\n\n

Las\n empresas energ\u00e9ticas de las ciudades en las que el metro se instal\u00f3 \nprimeramente no eran, por lo general, capaces de ofrecer la energ\u00eda \nnecesaria para hacerlo funcionar. Por ello, es normal que, al principio,\n este sistema de medio de transporte contase con su propia central de \nelectricidad, como bien ocurri\u00f3 en nuestro propio Madrid, la cual, por \ncierto, est\u00e1 disponible para visitar en el barrio Pac\u00edfico. Como \ncuriosidad, indicar que esta no s\u00f3lo lleg\u00f3 a abastecer todo el sistema, \nsino que, en momentos de precariedad como lo fue la Guerra Civil, dio \nsoporte el\u00e9ctrico a toda la ciudad.<\/p>\n\n\n\n

Con\n el transcurrir de los a\u00f1os y la mejora de la capacidad de las \nel\u00e9ctricas, la red pas\u00f3 a ser suministrada por estas, pues este proceso \npas\u00f3 a ser menos costoso.<\/p>\n\n\n\n

Sin embargo, se presentaba un problema considerable: la incompatibilidad entre corrientes. El metro precisa de corriente continua y las compa\u00f1\u00edas ofrecen corriente alterna.<\/strong><\/p>\n\n\n\n

Para poner soluci\u00f3n a eso se necesita llevar a cabo una transformaci\u00f3n de energ\u00eda que, a pesar de concebirla ahora de manera sencilla, tiene su trabajo.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Conectores y contactos Alfa\u00b4R en el metro<\/h3>\n\n\n\n

Es en este punto en el que nuestros conectores y contactos Alfa\u00b4R<\/a>\n entran en juego, pues esa labor de transformaci\u00f3n requiere de la \ngesti\u00f3n y modificaci\u00f3n de la red el\u00e9ctrica para la cual se precisa de \nuna red de subestaciones y que, por supuesto, se conforma con cantidad \nde productos de este tipo y de muchos otros.<\/p>\n\n\n\n

Estas\n se interconectan v\u00eda corriente alterna, lleg\u00e1ndoles, en el caso de \nnuestro pa\u00eds, 15000 voltios, a trav\u00e9s de un cableado rojo que vemos en \nlos t\u00faneles f\u00e1cilmente cuando viajamos. De esta manera se consigue que, \nen caso de darse un fallo en una subestaci\u00f3n, las dem\u00e1s puedan darle \nsoporte, formando, con ello, un sistema redundante.<\/p>\n\n\n\n

En\n cualquier caso, tenemos una energ\u00eda en media tensi\u00f3n que va a parar a \nuna subestaci\u00f3n rectificadora, la cual se encarga de estabilizar la \ntensi\u00f3n as\u00ed como de hacer que el voltaje sea menor para operar en l\u00ednea,\n de 600 o 1500 voltios. Es tambi\u00e9n en este punto en el que dicha \ncorriente pasa de ser alterna a ser continua.<\/p>\n\n\n\n

Una vez m\u00e1s, aportamos nuestro grano de arena con la instalaci\u00f3n de feeders<\/em><\/strong>, que son los que llevan esa alimentaci\u00f3n al cable de tendido del metro<\/em>. Su secci\u00f3n es variable, escogi\u00e9ndose seg\u00fan dos par\u00e1metros: Distancia a recorrer y tensi\u00f3n. Tambi\u00e9n damos aqu\u00ed con seccionadores<\/em><\/strong>, que posibilitan que la corriente llegue, por el pant\u00f3grafo, al tren y que, de este modo, alimente los equipos de este.<\/p>\n\n\n\n

Finalmente,\n saber que los cercan\u00edas tambi\u00e9n funcionan del mismo modo pero con una \nconversi\u00f3n de la energ\u00eda a 3000 voltios, que es la necesaria en el \ntendido ib\u00e9rico.<\/p>\n","_et_gb_content_width":"","inline_featured_image":false,"footnotes":""},"categories":[4],"tags":[],"class_list":["post-1976","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/posts\/1976","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/comments?post=1976"}],"version-history":[{"count":2,"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/posts\/1976\/revisions"}],"predecessor-version":[{"id":6972,"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/posts\/1976\/revisions\/6972"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/media\/1648"}],"wp:attachment":[{"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/media?parent=1976"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/categories?post=1976"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/alfarsl.es\/en\/wp-json\/wp\/v2\/tags?post=1976"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
