Abstract

Un dispositivo protector (10) de líneas (12) que transmiten senales telefónicas y/o de datos a una tensión de corriente continua predeterminada, nominalmente 48 volt. Un relé biestable (11) intercalado en el par de líneas presenta una salida normal cerrada (SALA) conectada a la instalación a proteger y una salida normal abierta (SALB), un rectificador (d3, D4, D7, D8) en cada una de dichas salidas del relé configurado con polaridad opuesta al rectificador de la otra salida del relé, un circuito de desconexión (19) formando un primer circuito serie (R1,. R2, R3,C1, C2) con el rectificador de dicha salida normal cerrada del relé, estando este primer circuito serie conectado a la bobina (15) de dicho relé de manera de energizarla en caso de sobretensión de dicha línea y conmutar dicho relé hacia su salida normal abierta (SALB1, SALB2), y un circuito de reconexión (21) que forma un segundo circuito serie con el rectificador de dicha salida normal abiertas del relé, estando este segundo circuito serie también conectado a la bobina de dicho relé de manera de conmutar dicho relé hacia su salida normal cerrada al cesar la sobretensión de dicha línea y retornar la tensión de línea al entorno de dicha tensión de corriente continua nominal predeterminada.A protective device (10) of lines (12) that transmit telephone and / or data signals at a predetermined DC voltage, nominally 48 volts. A bistable relay (11) interleaved in the pair of lines has a normal closed output (SALA) connected to the installation to be protected and a normal open output (SALB), a rectifier (d3, D4, D7, D8) in each of said relay outputs configured with polarity opposite the rectifier of the other relay output, a disconnection circuit (19) forming a first series circuit (R1, R2, R3, C1, C2) with the rectifier of said normal output closed from the relay, this first series circuit being connected to the coil (15) of said relay in order to energize it in case of overvoltage of said line and switch said relay to its normal open output (SALB1, SALB2), and a reconnection circuit (21 ) which forms a second series circuit with the rectifier of said normal output open from the relay, this second series circuit also being connected to the coil of said relay so as to switch said relay to its normal output closed when the overvoltage of di cha line and return the line voltage to the environment of said predetermined nominal direct current voltage.
