Abstract

Invenţia are ca obiect un detector pentru monitorizarea integrităţii unei conexiuni de împământare a unui aparat electric. Detectorul (18) conform invenţiei are borne de fază şi de nul (12 şi, respectiv, 13) pentru alimentarea cu curent a unui aparat electric (10), de la cablurile de fază şi de nul (14 şi, respectiv, 15) ale unei reţele electrice de alimentare, care are un punct de conexiune lapământ (GND) pentru conectarea bornei de împământare (17) a aparatului electric (10). Detectorul (18) se compune dintr-un circuit comparator diferenţial (31 şi 43) pentru compararea tensiunii bornei de nul (13) cu tensiunea bornei de împământare (17) a aparatului electric (10), şi pentru furnizarea unui semnal de defect, dacă diferenţa între cele două tensiuni depăşeşte un prag predeterminat. Detectorul (18) este conectat la cel puţin una din bornele de fază şi de nul (12 şi, respectiv, 13), acesta mai cuprinzând un comutator cu tranzistor (39), ce este acţionat de către un dispozitiv contactor (40) normal închis, în mod funcţional cuplat în detector (18), şi care este sensibil la semnalul de defect produs prin acesta.
