Abstract

Inventia se refera la domeniul masurarilor electrice si poate fi utilizata pentru masurarea rezistentei liniare a conductorului izolat fara deteriorarea izolatiei. Dispozitivul contine un generator de semnal de masurare (1) conectat cu o borna de iesire la masa, primul (3) si al doilea contact capacitiv (6) fiind amplasati adiacent conductorului supus masurarilor, un amplificator (4) conectat cu intrarea la primul contact capacitiv (3), un convertor de rezistenta negativa (5) conectat cu bornele de iesire, respectiv, la cel de-al doilea contact capacitiv (6) si la masa, un rezistor comandat (7), conectat la bornele de intrare ale convertorului de rezistenta negativa (5), un organ de nul (8)comandat in faza, conectat cu intrarea de semnal la iesirea amplificatorului (4), iar cu intrarea de referinta - la punctul circuitului convertoruluide rezistenta negativa (5) in care semnalul are aceeasi faza cu curentul din conductorul masurat, precum si un indicator de nul (9) conectat la iesirea organului de nul (8), totodata dispozitivul maicontine suplimentar un condensator (2) conectat intre cea de-a doua borna de iesire a generatorului(1) si primul contact capacitiv (3), iar contactele capacitive sunt amplasate unul fata de altul lao distanta egala lungimii segmentului masurat al conductorului izolat. Rezultatul inventiei consta in asigurarea masurarii cu precizie inalta a rezistentei liniare a conductorului izolat fara deteriorarea izolatiei.The invention relates to the field of electrical measurements and can be used to measure the linear resistance of the insulated conductor without damaging the insulation. The device contains a measurement signal generator (1) connected to a grounding terminal, the first (3) and the second capacitive contact (6) being located adjacent to the conductor subjected to the measurements, an amplifier (4) connected with the input to the first contact capacitive (3), a negative resistor converter (5) connected to the output terminals, respectively, to the second capacitive contact (6) and to the ground, a controlled resistor (7), connected to the input terminals of the converter of negative resistance (5), a null member (8) commanded in phase, connected with the signal input at the output of the amplifier (4), and with the reference input - at the point of the converter circuit negative resistance (5) in which the signal has the same the phase with the current from the measured conductor, as well as a zero indicator (9) connected to the output of the null member (8), at the same time the additional maicontine device a capacitor (2) connected between the second output terminal of the generator (1) and the first account capacitive act (3), and the capacitive contacts are located relative to each other at a distance equal to the length of the measured segment of the insulated conductor. The result of the invention consists in ensuring the high precision measurement of the linear resistance of the insulated conductor without damaging the insulation.
