Abstract

Circuito protector frente a sobretensiones. Comprende un limitador de tensión MOV (3) (Metal Oxide Varistors, Varistores de metal-óxido) dispuesto en serie con un limitador de tensión GDT (4) (Tubos de Descarga de Gas); se caracteriza porque en paralelo con el dispositivo GDT (4) se sitúa una resistencia (5) con un valor tal que la tensión que soporta el dispositivo GDT (4) es menor que su voltaje de mantenimiento de la conducción ("holdover voltaje"). En otra realización de la invención, en paralelo con el dispositivo MOV (3) se sitúa una resistencia (6) que junto con la resistencia (5) forman un divisor resistivo para que la tensión a la que está sometido el dispositivo GDT (4) en condiciones de régimen estacionario, sea menor que el "holdover voltaje" del GDT. La invención está indicada para sistemas de comunicaciones, preferentemente en aplicaciones de comunicación por la red eléctrica, ya que aumenta la eficacia de la protección al necesitar un "holdover voltaje" del dispositivo GDT (4) menor que el requerido convencionalmente.Protective circuit against surges. It comprises a MOV voltage limiter (3) (Metal Oxide Varistors, metal-oxide varistors) arranged in series with a GDT voltage limiter (4) (Gas Discharge Tubes); It is characterized in that in parallel with the GDT device (4) there is a resistance (5) with a value such that the voltage that supports the GDT device (4) is lower than its conduction maintenance voltage ("holdover voltage") . In another embodiment of the invention, a resistor (6) is placed in parallel with the MOV device (3) which together with the resistor (5) forms a resistive divider so that the voltage to which the GDT device is subjected (4) under steady state conditions, it is less than the "holdover voltage" of the GDT. The invention is indicated for communication systems, preferably in communication applications through the power grid, since it increases the protection efficiency by requiring a "holdover voltage" of the GDT device (4) lower than that conventionally required.
