Patent
A safety control device for detecting undesirable conditions
Description
The invention relates to safety control devices. It deals with a device adapted to transmit a warning signal further to the detection of an undesirable condition in an associated apparatus, said device comprising switching means comprising transistors mounted in a reaction path, feeding means for opening the switching means whenever an undesirable condition has been detected by sensors, whereby an oscillator is caused to stop oscillating, and an outlet device controlled by the oscillator stoppage. This can be applied to the supervision of nuclear reactor
Abstract (French)
L'invention concerne les appareils de commande de securite. Elle se rapporte a un appareil destine a transmettre un signal d'avertissement a la suite de la detection d'une condition indesirable dans un appareillage associe, et comprenant un dispositif de commutation comprenant des transistors montes dans un trajet de reaction, des alimentations destinees a ouvrir le dispositif de commutation apres detection d'une condition indesirable par les capteurs provoquant l'arret des oscillations d'un oscillateur et un dispositif de sortie commande par l'arret du fonctionnement de l'oscillateur. Ceci est applicable a la surveillance d'un reacteur nucleaireAdditional details
