Abstract

Inventia se refera la domeniul masurarilor electrice si poate fi utilizata pentru masurarea rezistentei liniare a microconductorului cu izolatie de sticla in proces de turnare. Dispozitivul contine un generator de semnal de masurare, conectat cu o borna de iesire la masa, un contact capacitiv, amplasat alaturat conductorului masurat, care este infasurat pe o bobina, un condensator, conectat cu un pol la contactul capacitiv, iar cu al doilea pol – la a doua borna de iesire a generatorului, un amplificator, conectat cu intrarea la contactul capacitiv, un convertor de rezistenta negativa, conectat cu o borna de iesire la masa, un rezistor comandat, conectat la bornele de intrare ale convertorului de rezistenta negativa, un organ de nul comandat in faza, conectat cu intrarea de semnal la iesirea amplificatorului, iar cu intrarea de referinta la punctul circuitului convertorului de rezistenta negativa, in care semnalul are aceeasi faza ca cel din conductorul masurat, si un indicator de nul, conectat la iesirea organului de nul. Bobina este executata din metal si este conectata electric cu cea de-a doua borna de iesire a convertorului de rezistenta negativa.The invention relates to the field of electrical measurements and can be used to measure the linear resistance of the microconductor with glass insulation in the casting process. The device contains a measuring signal generator, connected with a grounding terminal, a capacitive contact, located next to the measured conductor, which is wound on a coil, a capacitor, connected with a pole to the capacitive contact, and with the second pole. - at the second output terminal of the generator, an amplifier, connected with the input to the capacitive contact, a negative resistance converter, connected with a grounding output terminal, a controlled resistor, connected to the input terminals of the negative resistance converter, a zero-phase organ controlled in the phase, connected with the signal input at the amplifier output, and with the reference input at the point of the negative resistance converter circuit, in which the signal has the same phase as that of the measured conductor, and a null indicator, connected to the the exit of the organ from void. The coil is made of metal and is electrically connected to the second output terminal of the negative resistance converter.
