Abstract

Se proporciona un fusible de potencia para proteger una carga eléctrica sometida a ciclos de corriente transitoria en un sistema de alimentación eléctrica de corriente continua. El fusible incluye al menos un conjunto de elementos fusibles compuesto por un sustrato plano alargado, varios puntos débiles fusibles y un conductor. Los puntos débiles se forman en el sustrato y están espaciados longitudinalmente entre sí. El conductor se encuentra separado del sustrato y de los puntos débiles. El conductor consiste en una tira metálica sólida y alargada sin aberturas estampadas para los puntos débiles, lo que evita la fatiga termomecánica en el conductor al ser sometido a los ciclos de corriente transitoria. La tira metálica sólida y alargada incluye secciones de conexión coplanares montadas en los puntos débiles correspondientes y secciones que se extienden oblicuamente, dobladas fuera del plano de las secciones de conexión para sobresalir del sustrato. (Traducción automática con Google Translate, sin valor legal)A power fuse is provided to protect an electrical load subjected to transient current cycling in a direct current power supply system. The fuse includes at least one assembly of fusible elements consisting of an elongated flat substrate, several fusible weak points, and a conductor. The weak points are formed in the substrate and are spaced longitudinally apart. The conductor is separated from the substrate and the weak points. The conductor consists of a solid, elongated metal strip without stamped openings for the weak points, thus preventing thermomechanical fatigue of the conductor when subjected to transient current cycling. The solid, elongated metal strip includes coplanar connecting sections mounted at the corresponding weak points and obliquely extending sections, bent out of the plane of the connecting sections to protrude from the substrate.
