Abstract
Un supresor de ondas de choque o sobrevoltajes particularmente adecuado para protección lateral secundaria de transformadores de distribución, incluyendo un disco varistor de bajo voltaje, de alta energía, teniendo electrodos dispuestos alrededor de sus superficies de confrontación y un pasador de resorte auto-comprimible con brazos de resorte dispuestos alrededor del varistor para proporcionar la fuerza de compresión necesaria para mantener buen contacto eléctrico entre los electrodos y el varistor. El supresor incluye terminales para interconectar eléctricamente los electrodos con el aparato eléctrico que está siendo protegido por el supresor. El supresor incluye además un revestimiento dieléctrico que envuelve sustancialmente el varistor, el pasador de resorte y los electrodos. El supresor no requiere de otro alojamiento. Los brazos de resorte pueden hacerse en una variedad de configuraciones y formas y pueden entrelazarse con sub-conjuntos adyacentes de pasador de resorte y de varistor de modo de formar supresores trifásicos u otros supresores de polos múltiples. Una forma de trifásicos u otros supresores de polos múltiples. Una forma de realización preferida particular de un supresor de polos múltiples incluye dos o mas varistores y un pasador de resorte teniendo un miembro de base central y dos brazos de resorte. Los brazos de resorte forman lóbulos dispuestos en cualquier lado del miembro de base, y el miembro de base y los brazos de resorte son todos formados integramente de una sola pieza de material.A shock wave or surge suppressor particularly suitable for secondary side protection of distribution transformers, including a high-voltage, low-voltage varistor disk, having electrodes arranged around their confronting surfaces and a self-compressing spring pin with arms springs arranged around the varistor to provide the compression force necessary to maintain good electrical contact between the electrodes and the varistor. The suppressor includes terminals to electrically interconnect the electrodes with the electrical apparatus that is being protected by the suppressor. The suppressor further includes a dielectric coating that substantially wraps around the varistor, spring pin, and electrodes. The suppressor does not require other housing. The spring arms can be made in a variety of configurations and shapes and can be interlocked with adjacent spring pin and varistor sub-assemblies to form three-phase suppressors or other multi-pole suppressors. A form of triphasic or other multi-pole suppressors. A particular preferred embodiment of a multi-pole suppressor includes two or more varistors and a spring pin having a central base member and two spring arms. The spring arms form lobes arranged on either side of the base member, and the base member and spring arms are all integrally formed of a single piece of material.
