Abstract

PROTEçãO CONTRA SOBRETENSãO EM LINHAS DE TELEFONE/DADOS, ADEQUADA PARA INSTALAçõES COM CONEXõES DE BAIXA QUALIDADE COM A TERRA. Apresente invenção refere-se a um dispositivo de proteção (10) utiliza um relé engatador (11) de bobina única (15) para desacoplar uma instalação de telefone e / ou de dados a partir das linhas transmissão CC (12) no caso de um distúrbio de sobretensão / CA na linha. um circuito disparador (19) e um circuito de reinicialização (21) são respectivamente conectados com os bornes normalmente fechados (OUTA1, OUTB1) e normalmente abertos (OUTA2, OUTB2) dorelé para monitorar a voltagem da linha utilizando uma conexão com a terra como uma voltagem de referência, alimentando, respectivamente, diretas de disparo (23) ou de reinicialização (25) para a bobina para comutar o relé, Por conseqüência, o dispositivo de proteção pode permitir de maneira eficaz uma conexão de alta resistência, barata, com a terra. A direta de reinicialização é alimentada para a bobina do relé por meio de um circuito de transistor (Q1, Q2) somente após o distúrbio ter cessado, após a voltagem de transmissão nominal ter sido restaurada e após a linha ter se estabilizado durante auguns segundos.PHONE / DATA OVERVOLTAGE PROTECTION, SUITABLE FOR INSTALLATIONS WITH LOW QUALITY EARTH CONNECTIONS. The present invention relates to a protective device (10) utilizing a single coil relay (11) relay (15) to decouple a telephone and / or data facility from the DC transmission lines (12) in the case of a overvoltage / AC disturbance on the line. a trip circuit (19) and a reset circuit (21) are respectively connected to normally closed (OUTA1, OUTB1) and normally open (OUTA2, OUTB2) terminals to monitor the line voltage using a ground connection as a reference voltage, respectively by supplying tripping (23) or resetting (25) directives to the coil to switch the relay. As a result, the protective device can effectively enable a cheap, high-resistance connection to the relay. Earth. The reset direct is fed to the relay coil via a transistor circuit (Q1, Q2) only after the disturbance has ceased, after the rated transmit voltage has been restored, and after the line has stabilized for a few seconds.
