Abstract

El transformador eléctrico 1 comprende un tanque 4 que contiene un dieléctrico líquido o gaseoso, 5, y en el cual tanque se hallan sumergidos:un circuito primario y un circuito secundario, y un dispositivo de proteccion conectado al circuitoprimario y que comprende un disyuntor 15 controladopor medios de disparo y uno o más fusibles 11. Los fusibles están dispuestos entre un pasante 6 del tanque y el disyuntor 15. Los fusibles 11, el disyuntor 15y los medios de disparo, están asociadosentre sí de manera tal que bajo condiciones correspondientes a un cortocircuito en las terminales del circuitosecundario, los medios de contacto del disyuntor se separan e interrumpen la corriente sin que el fusible empiece a fundirse, y de maneratal queexi ste un valor de umbral para la intensidad de la corriente que fluye en el fusible, inferior a la capacidad de ruptura del polo correspondientedel disyuntor y por arriba del cual valor de umbral ha tenido lugar la fusion del fusible antesque una orde n para la separacion de los medios de contactoemitida por los medios de disparo haya sido capaz de ocasionar la separacion de los contactos.The electric transformer 1 comprises a tank 4 containing a liquid or gaseous dielectric, 5, and in which tank they are submerged: a primary circuit and a secondary circuit, and a protection device connected to the primary circuitry and comprising a circuit breaker 15 controlled by trip means and one or more fuses 11. The fuses are arranged between a pass-through 6 of the tank and the circuit breaker 15. The fuses 11, the breaker 15 and the trip means, are associated with each other in such a way that under conditions corresponding to a short circuit at the terminals of the secondary circuit, the contact means of the circuit breaker separate and interrupt the current without the fuse starting to blow, and so that there is a threshold value for the intensity of the current flowing in the fuse, lower than the breaking capacity of the corresponding pole of the circuit breaker and above which threshold value the fuse has fused before a order for the separation of the contact means emitted by the firing means has been able to cause the separation of the contacts.
