Abstract
Inventia se refera la o instalatie pentru supravegherea etanseitatii cablurilor de telecomunicatii prin semnalizarea electropneumatica a scaderilor de presiune în anumite puncte ale traseului mentinut sub presiune cu aer uscat. înstalatia, conform inventiei, în scopul supravegherii continue si centralizate a etanseitatii cablurilor de telecomunicatii, precum si a indicarii locului cu deranjament, este constituita din unu pâna la zece dispozitive de semnalizare si control pneumatic, amplasate câte unul în fiecare statie automata nedeservita si la care sunt conectate pneumatic si electric extremitatile sectiunilor de cablu, precum si dintr-un panou de supraveghere, montat în statia de frecventa, la care sunt conectate dispozitivele de semnalizare si control pneumatic, care sesizeaza scaderile de presiune din cablu si declanseaza sistemul de alarmare, dispozitivul de semnalizare si control pneumatic fiind constituit dintr-un distribuitor pneumatic, dintr-un presostat diferential, care sesizeaza scaderea presiunii din cablu si actioneaza un releu, introducând în circuitul electric al buclei de curent continuu un rezistor.The invention relates to a device for monitoring the tightness of telecommunication cables by electropneumatic signaling of the pressure drops at certain points of the dry air pressure controlled route. According to the invention, the installation according to the invention for the purpose of continuous and centralized monitoring of the tightness of the telecommunication cables, as well as the indication of the disturbance site, consists of one to ten pneumatic signaling and control devices, one at each unattended automatic station and at which are pneumatically and electrically connected to the end of the cable sections as well as to a surveillance panel mounted in the frequency station to which the signaling and pneumatic control devices are connected which senses the pressure drops in the cable and triggers the alarm system, signaling and pneumatic control consisting of a pneumatic distributor, a differential pressure switch, which senses the pressure drop in the cable and operates a relay, introducing a resistor into the electric loop of the DC loop.
