Title (EN) HIGH VOLTAGE PROTECTION RESISTOR
(FR) RESISTANCE DE PROTECTION HAUTE TENSION
Abstract:
(EN) A protection arrangement for a high voltage tube includes a low inductance disk resistor connected in series with the anode of the tube. When an electrical discharge occurs within the tube, the increase anode current flows through the resistor which absorbs much of the potentially harmful energy surge. The resistor is a disk resistor comprising two counter-wound planar spirals of resistance wire electrically connected in parallel and counter-wound with respect to one another. Connection arrangements are provided to both electrically and mechanically connect the resistor to the high voltage tube.
(FR) Un agencement de protection pour un tube à haute tension comprend une résistance en forme de disque de faible inductance connectée à l'anode du tube. Lorsqu'une décharge électrique se produit à l'intérieur du tube, le courant d'anode augmenté passe dans la résistance qui absorbe une grande partie de la pointe d'énergie potentiellement préjudiciable. La résistance est une résistance en forme de disque comprenant deux spirales planes contre-enroulées de fil de résistance relié électriquement en parallèle et contre-enroulées l'une par rapport à l'autre. Des agencements de connexion à la fois électrique et mécanique relient la résistance au tube à haute-tension.
