Abstract

1.- El relé Buchholz (1) para la proteccion de equipos eléctricos de potencia aislados con aceite que incluye: - un marco de soporte (2) en contacto con el aceite; - los medios de manejo (3) acoplados con dicho marco de soporte (2) con respecto al cual son movibles; - los medios interruptores (4), conectados operativamente con dichos medios de manejo (3) y capaces de habilitar/deshabilitar un circuito de alarma y/o un circuito de desconexion de dicho equipo eléctrico; - Por lo menos una valvula de regulacion (5) del flujo de aceite (F), acoplada con dicho marco de soporte (2), apta para ser afectada por el flujo de aceite (F) para definir una primera posicion en la cual deshabilite dicho circuito de desconexion de dicho equipo eléctrico y una segunda posicion en la cual, si el flujo de aceite excede un cierto umbral, habilita dicho circuito de desconexion de dicho equipo eléctrico, caracterizado porque incluye medios de contraste (6) asociados con dicho marco de soporte (2) y con dicha valvula (5) para mantener esta ·ltima en dicha primera posicion. 2.- El relé (1) como en la reivindicacion 1) caracterizado porque dicho medio de contraste (6) incluye un primer elemento ferromagnético (10), aplicado a dicha valvula de regulacion (5) y un segundo elemento ferromagnético (11), enfrentado a dicho primer elemento ferromagnético (10), asociado con dicho marco de soporte (2) por medio de una lamina de referencia (12).1.- The Buchholz relay (1) for the protection of electrical power equipment insulated with oil that includes: - a support frame (2) in contact with the oil; - the operating means (3) coupled with said support frame (2) with respect to which they are movable; - the switching means (4), operatively connected with said operating means (3) and capable of enabling / disabling an alarm circuit and / or a disconnection circuit of said electrical equipment; - At least one valve (5) for regulating the oil flow (F), coupled with said support frame (2), suitable for being affected by the oil flow (F) to define a first position in which to disable said circuit of disconnecting said electrical equipment and a second position in which, if the oil flow exceeds a certain threshold, it enables said circuit of disconnection of said electrical equipment, characterized in that it includes contrast means (6) associated with said frame of support (2) and with said valve (5) to maintain the latter in said first position. 2. The relay (1) as in claim 1) characterized in that said contrast medium (6) includes a first ferromagnetic element (10), applied to said regulating valve (5) and a second ferromagnetic element (11), facing said first ferromagnetic element (10), associated with said support frame (2) by means of a reference sheet (12).
