Abstract

Inventia se refera la un circuit electric de protectie a retelelor de medie tensiune utilizînd un releu de distanta, avînd rolul de a asigura declansarea foarte rapida selectiva a liniilor de medie tensiune la aparitia scurt-circuitelor aparute pe prima portiune a liniilor de medie tensiune, cît si declansarea rapida selectiva a liniilor de medie tensiune de lungime mai mare la aparitia scurtcircuitelor pe a doua portiune a liniilor de medie tensiune utilizînd un releu de la distanta, conform inventiei, utilizeaza o protectie de distanta montata de forta bazata pe o schema care contine relee intermediare, care sesizeaza daca protectiile maximale temporizate ale liniilor au demarat.The invention relates to a medium-voltage electrical circuit protection circuit using a relay having the role of ensuring very selective triggering of the medium voltage lines at the occurrence of the short circuits appearing on the first portion of the medium voltage lines, and the selective short-time triggering of the medium-voltage lines of longer length at the occurrence of short-circuits on the second portion of the medium voltage lines using a remote relay according to the invention uses a force-mounted distance protection based on a circuit that contains relays intermediate, which notifies if the maximum timed line protection has started.
