Abstract
Inventia se refera la un dispozitiv pentru masurarea curentilor alternativi în retele de joasa tensiune. Dispozitivul conform inventiei cuprinde un cleste ampermetric, care este format dintr-un miez magnetic pe a carui portiune fixa este situata o bobina, care prezinta la borne o tensiune proportionala cu curentul de masurat ce trece printr-un conductor în scopul mpsurarii curentilor alternativi într-o gama larga de valori, tensiunea de la iesirea clestelui ampermetic fiind aplicta, prin intermediul atasabil, constituit dintr-o punte redresoare, realizata cu diode redresoare, a carui iesire este racordata la un volmetru electronic realizat cu doua tranzitoare conectate pe doua diagonale ale unei punti, diagonale pe care sunt conectate elemente de reglare a punctului de zero, emitoarele tranzistoarelor fiind conectate la un instrument universal de masura continuu si un grup de potentiometre pentru reglarea punctului de zero si a sensibilitatii adaptorului.The invention relates to a device for measuring alternating currents in low voltage networks. According to the invention, the device comprises an ampermetric clamp which consists of a magnetic core on which the fixed part is located a coil, which presents at the terminals a voltage proportional to the measuring current flowing through a conductor for the purpose of measuring the alternating currents, a wide range of values, the voltage at the output of the ampermetal clamp being applied by means of a rectifier bridge, made of rectifier diodes, whose output is connected to an electronic choke made with two transients connected on two diagonals of a bridges, diagonals on which zero point adjustment elements are connected, transistor emitters being connected to a universal continuous measuring instrument and a set of potentiometers for zero point adjustment and adapter sensitivity.
