operating modes of various installations amplifying electrical signals using optothyristors is
presented and the ways of their inclusion in electrical circuits are presented. The optoelectronic
contactless voltage relays were tested in laboratory conditions to obtain an input-output
characteristic and a form of capacitance voltage. Based on the improvement of the proposed
circuit, a circuit of an optoelectronic contactless voltage relay is developed and provide a high
degree of reliability. The simulation of the proposed voltage relay circuits is performed using the
MATLAB R2014a program, the results of which show that changes in the shape of the output
voltage curve are close to a sinusoid and coincide with the results obtained analytically. As a
result the obtained conditions of use make it possible to obtain a voltage with a sinusoidal shape
on the load and achieve a relay return coefficient close to unity.
Maqolada optotiristorli rezistiv zanjirlar tahlili natijasi asosida optik-elektronli kontaktsiz
kuchlanish relesining yangi sxemasi ishlab chiqilib, uni elektr ta'minoti tizimida ishlatish
masalasi ko'rilgan hamda optotiristorlar yordamida elektr signallarni kuchaytirish yo'li bilan
har hil qurilmalarning ish rejimlarini boshqarish mumkinligi va ularni elektr zanjiriga ulash
to'g’risida to'xtalib o'tilgan. Optik-elektronli kontaktsiz kuchlanish relesini tajribada sinash
natijasidan, kuchlanishning “kirish-chiqish” xarakteristikasi va sig’imdagi kuchlanishni egri
chiziq shakli keltirilgan. Taklif etilgan sxemani takomillashtirish asosida optik-elektronli
kontaktsiz kuchlanish relesining sxemasi ishlab chiqilgan va u yuqori darajadagi ishonchli-likni
ta'minlaydi. Taklif qilinayotgan kuchlanish relesining sxemasi MATLAB R2014a dasturi
yordamida modellashtirildi, natijada chiqish kuchlanishi egri chiziq shaklining o'zgarishini
sinusoidaga yaqinligi va analitik yo'l bilan olingan natijalarga mos kelishi aniqlandi.
Shuningdek, relening ishlash shartiga ko'ra yuklama kuchlanishi shaklining sinusoidaligi va
qaytish koefficientining birga yaqin bo'lishiga imkon berdi.

В статье на основе результатов анализа существующих оптотиристорных
резистивных цепей разработана новая схема оптоэлектронного бесконтактного реле
напряжения и рассмотрено применение его в системе электроснабжения. Представлена
возможность управления рабочими режимами различных установок усиления
электрических сигналов с помощью оптотиристоров и приведены способы их включения в
электрические цепи. Проведены испытания оптоэлектронных бесконтактных реле
напряжения в лабораторных условиях для получения характеристик “вход-выход” и
формы напряжения емкости. На основе усовершенствования предложенной схемы
разработана схема оптоэлектронного бесконтактного реле напряжения, которая
обеспечивают высокую степень надѐжности. Моделирование предложенной схемы реле
напряжения производится при помощи программы MATLAB R2014а, результаты
которой показывают, что изменения формы кривой выходного напряжения близки к
синусоиде и совпадают с результатами полученных аналитическим путем. Условия
использования реле позволяют получить на нагрузке напряжение с синусоидальной
формой и достичь коэффициент возврата реле близким к единице.
