Abstract

Un miembro de resorte y un miembro de canal asociado solicitan forzadamente un lingote de soldadura hasta acoplamiento con un electrodo de tierra del detenedor de corriente transitoria anormal. Cuando la soldadura se funde en respuesta a una condición de sobrecarga térmica, el miembro de canal hace que la soldadura fundida procede del lingote fluya preferencialmente a lo largo de una trayectoria que establece un cortocircuito de baja resistencia entre los electrodos. El flujo de la soldadura a ubicaciones deseadas se incrementan mediante fundente de soldadura, que de preferencia es un tipo de colofonia, que tiene propiedades dieléctricas sustanciales.A spring member and an associated channel member forcibly bind a solder ingot into engagement with a ground electrode of the abnormal surge arrester. When the solder melts in response to a thermal overload condition, the channel member causes the molten solder from the ingot to flow preferentially along a path that establishes a low resistance short circuit between the electrodes. The flux of the solder to desired locations is increased by solder flux, which is preferably a type of rosin, which has substantial dielectric properties.
