Maxsulot haqida
RHP turidagi HGIS elektr tashkiloti yangi turdagi yuqori boslikli elektr tashkiloti hisoblanadi. U GIS kombinatsiya elektr tashkilotingizning kompaktlik, yuqori ishonch va kam muntazam ish va xizmat talablar kabi afzalliklarini saqlaydi, ayniqsa busbar konventionel AIS rejimida joylashtirish uchun innovatsion ravishda saqlanadi. Bu dizayn aniq tarzda traditsionel AIS tashkilotingiz bilan bog'liq bo'lgan kamchiliklarni, jumladan katta hajm, ko'p ulash punktlar va yuqori tekshirish va xizmat ishlar miqdorini yengilaydi.
U 40.5kV dan 145kV gacha va undan past qismlardagi elektr uzatish va taqsimot tizimlari uchun mos keladi, jumladan elektr stansiyalarda, transformator stansiyalarda, temir yo'llar stansiyalarda, bandarlarda va katta sanoat va kengash shirkatlarda. Xususan, bu to'g'ridan-to'g'ri maydon chegaralangan loyihalar, masalan, tog'li transformator stansiyalari va shahar transformator stansiyalari uchun juda yaxshi va ichki, tashqi yoki dam o'rmonlari ustiga o'rnatish mumkin.
Maxsulot Komponentlari
Asosiy xususiyatlari
Chaqaloq/qo'shilish klyuchlari operatsional ishonchni buzish muammolari haqida haqiqiy yechim;
Yuqori darajadagi o'z-mazkur interrupsiya va modulyar struktura ishonchni oshirish uchun;
Diskli izolyatorlar sonini bekor qilish yoki radikal ravishda pasaytirish ishonchni oshirish uchun;
Maxsus ishlab chiqarish texnikalaridan foydalanish flangelar sonini kamaytiradi, shuning uchun gaz chiqish ehtimoli minimalga soladi；
Tashqi o'rnatilgan CT ishonch va xavfsizlikni oshirish uchun;
Komplektlangan struktura va moslashuvchan joylashuv;
AIS ga nisbatan nisbiy ravishda ekonomik.
