Abstract
Inventia se refera la un dispozitiv pentru verificarea calitatii izolatiei tolelor de transformator. Dispozitivul conform inventiei, este constituit dintr-un traductor de curent ce utilizeaza un tranzistor conectat cu un tiristor si o dioda electroluminiscenta care se aprinde în momentul cand curentul prin rezistenta de izolatie masurata depaseste o valoare maxim admisibila, un traductor de tensiune cu prag reglabil format dintr-un tranzistor, un tiristor si o dioda electroluminiscenta care se aprinde daca rezistenta de izolatie este mai mare decat o valoare minim admisibila corespunzatoare tolelor de transformatoare mici, un alt traductor de tensiune cu prag reglabil format dintr-un tranzistor un tiristor si o dioda electroluminiscenta care se aprinde daca rezistenta de izolatie masurata, depaseste o valoare minim admisibila corespunzatoare tolelor de transformatoare mari, alimentarea dispozitivului fiind realizata prin niste borne de la o sursa de tensiune continua reglabila.The invention relates to a device for checking the insulation quality of the transformer wires. According to the invention, the device consists of a current transducer using a transistor connected to a thyristor and an electroluminescent diode which ignites when the current through the measured insulation resistance exceeds a maximum permissible value, an adjustable threshold voltage transducer from a transistor, a thyristor and an electroluminescent diode which ignites if the insulation resistance is greater than a minimum admissible value corresponding to the small transformer wires, another voltage transducer with an adjustable threshold consisting of a thyristor transistor and a diode electroluminescence that ignites if the measured insulation resistance exceeds a minimum admissible value corresponding to the large transformer wires, the power supply of the device being made by means of some terminals from an adjustable continuous voltage source.
