Strelkani ikki simli boshqarish sxemasini tahlil qilish
Ishdan maqsad: Strelkani 2-simli boshqarish sxemasi misolida strelkani boshqarish qurilmasini ishlash algoritmini o‘rganish.
Strelka boshqarish va nazorat qilish obyekti hisoblangani sababli uning to‘liq prinsipial elektr sxemasi boshqaruvchi va nazorat qiluvchi zanjirlar sxemalaridan tashkil topgan bo‘ladi.
Hisobot:
1.4-rasm. Strelkali boshqarishning strukturaviy sxemasi
Relelarning vazifasi va turlari:
