Abstract
Description
Aislador de bucle.Loop isolator.
La invención se refiere a un aislador de bucle con un componente de aislador en forma de bucle que está unido con guardacabos de conexión opuestos unos a otros.The invention relates to a loop insulator with a loop-shaped insulator component that is attached to connecting thimbles opposite each other.
Por ejemplo la publicación previa de Siemens AG con el número de pedido A52813-W3001-A0001-02-00 B1 da a conocer un aislador de bucle de este tipo. Los aisladores de bucle SICAT 8WL3001/3002 descritos en dicha publicación se aplican para aislar la línea área de alimentación activa de ferrocarriles eléctricos del potencial de tierra. El componente de aislador en forma de bucle está compuesto de plástico reforzado con fibra de vidrio, y en concreto de un cabo de plástico reforzado con fibra de vidrio cerrado en si mismo. En extremos opuestos de dicho elemento de aislador en forma de bucle está dispuesto, en cada caso, una armadura de conexión que se denomina guardacabo de conexión. Estos guardacabos de conexión muchas veces están fabricados a partir de una aleación de cobre y aluminio. En la fabricación las fibras de vidrio del componente de aislador empapadas con resina epoxi se bobinan directamente en los guardacabos de conexión y allí se endurecen.For example the previous publication of Siemens AG with the order number A52813-W3001-A0001-02-00 B1 discloses such a loop isolator. Insulators of SICAT 8WL3001 / 3002 loop described in said publication apply to isolate the active feed area line from electric railways of the ground potential. The component of loop-shaped insulator is made of reinforced plastic with fiberglass, and in particular of a plastic cape reinforced with fiberglass closed in itself. At opposite ends of said loop-shaped insulator element is arranged, in each case, a connection frame that is called a connection thimble. These connection thimbles are often made from of an alloy of copper and aluminum. In manufacturing the fibers Glass component insulator soaked with epoxy resin is winding directly into the connecting thimbles and there harden.
Los guardacabos de conexión conocidos siempre disponen de aberturas circulares, en los que se sujetan componentes de conexión como cuerdas, alambres o pernos. En las aberturas están situados insertos de guardacabos de aleación de cobre y aluminio, de cobre, latón o de poliamida. El componente de aislador en forma de bucle rodea los guardacabos de conexión.The known connection thimbles always they have circular openings, in which components are held of connection as ropes, wires or bolts. In the openings are located copper and aluminum alloy thimble inserts, Copper, brass or polyamide. The insulator component in form loop around the connection thimbles.
Los guardacabos de conexión conocidos de los aisladores de bucle y componentes de conexión están compuestos de metales distintos, que presentan tensiones electroquímicas distintas. En consecuencia debido a la humedad del aire puede producirse corrosión electroquímica. Además en el caso de guardacabos de conexión de latón no puede excluirse una corrosión por tensofisuración.The known connection thimbles of the loop insulators and connection components are composed of different metals, which have electrochemical stresses different. Consequently due to the humidity of the air can electrochemical corrosion occur. Also in the case of brass connection thimble cannot prevent corrosion by tensofisuration.
El documento DE 20 01 779 A describe un aislador de bucle de fibra de vidrio con guardacabos que pueden estar compuestos de plástico. El documento DE 679 226 C describe un aislador de bucle con aislamiento de porcelana de manera parcial.Document DE 20 01 779 A describes an insulator fiberglass loop with thimbles that can be plastic compounds Document DE 679 226 C describes a porcelain insulated loop insulator so partial.
La invención se basa en el objetivo de presentar un aislador de bucle no corrosible y por lo tanto que esté dispuesto para el uso durante más tiempo que un aislador de bucle habitual hasta el momento.The invention is based on the objective of presenting a non-corrosive loop insulator and therefore be ready for use for longer than a loop insulator usual so far.
Según la invención este objetivo se alcanza dado que los guardacabos de conexión están compuestos enteramente de cerámica.According to the invention this objective is achieved given that connection thimbles are composed entirely of ceramics.
Al evitar que dos metales que reaccionan de manera electroquímica linden uno con otro, se evita la corrosión electroquímica. Al no utilizar selectivamente metales o aleaciones como latón con peligro de tensofisuración, se evita la corrosión por tensofisuración.By preventing two metals that react from electrochemical way linden with each other, corrosion is avoided electrochemistry. By not selectively using metals or alloys Like brass with danger of stress cracking, corrosion is avoided by tensofisuration.
El material no metálico es una cerámica. Así se consigue la ventaja especial de utilizar un material no metálico mecánicamente estable.The non-metallic material is a ceramic. Thus get the special advantage of using a non-metallic material mechanically stable
Se consigue la ventaja especial de que el aislador de bucle no se corroe a pesar de las exposiciones atmosféricas y por lo tanto se facilita un tiempo de operación más largo que en los aisladores de bucle anteriores.You get the special advantage that the loop insulator does not corrode despite exposures atmospheric and therefore a longer operating time is facilitated long than in the previous loop insulators.
