Abstract
Inventia face parte din categoria metodelor si instrumentelor de masurat marimii neelectrice pe cale electrica. Inventia are posibilitati largi de aplicare, în primul rând în actionarile cu turatie reglabila bazate pe masina sincrona, dar si în alte domenii de utilizare a masinilor sincrone, ca marime suplimentara pentru reglarea excitatiei etc. Dispozitivul este adecvat pentru masuratori în standurile de probe si pentru cercetari stiintifice. Metoda se bazeaza pe folosirea unui disc, cu fante, cu doua piste, a unui traductor optoelectronic, care se fixeaza pe arbore asa fel încât, la mers în gol, semnalul logid furnizat traductorul optoelectronic corespunzator fantelor de pe o pista sa coincida cu semnalul logic corespunzator tensiunii de faza, furnizat de un traductor. Când masina se încarca, între cele doua semnale apar defazaje. Un numarator numara impulsurile furnizate de disc, corespunzatoare celei de a doua piste în intervalul corespunzator unghiului de defazaj si le afiseaza zecimal. Un numarator binar face acelasi lucru, oferind semnalul în cod binar pe o magistrala de sapte biti sau unui convertor digital-analogic. Pentru marirea rezolutiei aparatului unghiurile mici pot fi amplificate prin deplasarea în registrele de memorare pe perioada dintre doua masuratori.The invention is part of the category of methods and instruments for measuring non-electric size by electric means. The invention has wide application possibilities, first of all in synchronous speed-controlled drives based on the synchronous machine, but also in other fields of use of synchronous machines, as an extra size for adjusting the excitation etc. The device is suitable for measurements in sample stands and for scientific research. The method is based on the use of a slit disk with two tracks of an optoelectronic transducer, which is fixed to the shaft so that when the idle signal supplied the optoelectronic transducer corresponding to the slots on a track coincides with the logic signal corresponding to the phase voltage supplied by a transducer. When the car is charging, there is a defrost between the two signals. A counter counts the pulses provided by the disk corresponding to the second track in the range corresponding to the phase angle and displays them in decimal. A binary counter does the same, giving the binary code signal on a seven-bit bus or a digital-to-analog converter. To increase the resolution of the device, small angles can be amplified by moving to the memory registers for the period between two measurements.
