ANNOTATSIYA
Ma’lumki, elektr energiyasi ishlab chiqarishda sinxron generatorlar asosiy
elektromexanik o’zgartkich hisoblanadi. Biroq an’anaviy turdagi sinxron
generatorlarda kontakt halqa-cho’tka tizimining mavjudligi ularning asosiy
kamchiliklaridan biri hisoblanadi. Shuning uchun sinxron generatorlarni
takomillashtirish bugungi kundagi muhim vazifalardan biridir. Cho’tkasiz turdagi
sinxron generatorlardan foydalanish ushbu muammoning yechimidir.
Ushbu maqolada cho’tkasiz turdagi sinxron generatorlardan foydalanish
masalalari tahlil etilgan. Maqolada cho’tkasiz sinxron generatorning elektr sxemasi
keltirilgan va ularning an’anaviy turdagi sinxron generatorlarga nisbatan afzallik
jihatlari keltirib o’tilgan.
Kalit so’zlar:
kontakt halqa-cho’tka tizimi, cho’tkasiz sinxron generator,
qo’zg’atish chulg’ami, qo’zg’atkich, to’g’rilagich, elektr sxema.
USE OF BRUSHLESS EXCITING SYSTEM IN SYNCHRONOUS
GENERATORS
ABSTRACT
It is known that synchronous generators are the main electromechanical
converters in power generation. However, the existence of a contact ring-brush
system is the main disadvantage of traditional synchronous generators, therefore, the
improvement of synchronous generators is one of the main tasks today. The use of
brushless generators is the solution to this problem. This article analyzes the issues
of using synchronous brushless generators. The electric circuit of the brushless
generator and its advantages over the traditional synchronous generators is
presented.
