Uch fazali a uchun. c . To'g'ridan-to'g'ri tarqatish yoki foydalanish tizimlariga ulanishi uchun mo'ljallangan 50 Gts yoki 60 Gts chastotali mashinalar uchun nominal kuchlanishlar IEC 60038 da berilgan nominal kuchlanishlardan olinishi kerak.

Izoh Katta yuqori kuchlanish uchun a. c . mashinalari, kuchlanish optimal ishlashi uchun tanlangan bo'lishi mumkin. a uchun. c . statik konvertorlarga ulangan mashinalar kuchlanish, chastota va to'lqin shaklidagi ushbu cheklovlar qo'llanilmaydi. Bunday holda, nominal kuchlanishlar kelishilgan holda tanlanishi kerak. IEC 60034-18-41 ga muvofiq, kuchlanish manbasi konvertorlari tomonidan ta'minlash uchun maxsus mo'ljallangan I turdagi izolyatsiya tizimlariga ega elektr mashinalari uchun ishlab chiqaruvchi IEC 60034-18-41 ga muvofiq impuls kuchlanish izolyatsiyasi sinfini (IVIC) belgilashi mumkin. izolyatsiya tizimi. Bunday holda, izolyatsiya tizimi fazadan fazaga uchun IVIC C va fazadan erga uchun IVIC B uchun yoki foydalanuvchi va ishlab chiqaruvchi o'rtasida boshqacha tarzda kelishilgan bo'lishi kerak. IVIC darajasi hujjatlarda va afzalroq bo'lsa, nom belgisida ko'rsatilishi kerak (10.2 ga qarang).

NOTE For more information on special considerations for converter fed machines , see IEC TS 60034-25. Any bus transfer or fast reclosing of an a . c . machine , as it might occur , for example , due to the voltage ride through requirements of grid codes , can lead to very high peak currents endangering the stator winding overhang and to a very high peak torque of up to 20 times rated torque endangering the mechanical structure including the coupling and the driven or driving equipment . Bus transfer or fast reclosing is therefore only allowed if specified and accepted by the manufacturers of electric machine and driven equipment . For ratings s 10 MW or MVA , slow reclosing exceeding 1.5 times the open circuit time constant is allowed , if specified and accepted by the manufacturers of the electric machine and the driven equipment . For ratings >10 MVt yoki MVA, sekin qayta yopish uchun ruxsat etilgan minimal vaqt tizim integratori tomonidan to'liq tizimning vaqtinchalik tahlili bilan aniqlanishi kerak va elektr mashinasi va boshqariladigan uskunalar ishlab chiqaruvchilari tomonidan qabul qilingan taqdirda ruxsat etiladi.
