Nolinchi ketma-ketlikdagi oqim transformatori qanday kombinatsiyalangan holda ishlatiladi

Nolinchi ketma-ketlikdagi oqim transformatori tashqi ko'rinishida ikkita dumaloq temir qutiga o'xshaydi, lekin u ham dizel generatorining tarkibiy qismidir. Uning tuzilishi oddiy o'tkazgichli oqim transformatoriga o'xshaydi, faqat uning asosiy o'rashi himoyalangan tizimning uchinchi qismidir. Har bir fazaning o'tkazgichi, ikkilamchi o'rash birlamchi tizimning nol ketma-ketlik oqimini aks ettiradi.

The Zero Sequence Current Transformer should be installed on the bottom plate of the switchgear and should be fixed by a reliable bracket. However, some manufacturers or construction units install the Zero Sequence Current Transformer> current transformer on the bracket under the switchgear bottom plate, and some even bundle the Zero Sequence Current Transformer>kabeldagi oqim transformatori, bu kalit kabinasining umumiy muhrlanishini buzadi. Asos sifatida, u ko'plab yashirin xavflarni qoldirib, na xavfsiz, na changga chidamli, na mayda hayvonlardir.

After the cable terminal head passes through the external Zero Sequence Current Transformer> current transformer, the relative position of the metal shielded ground wire of the cable and the external Zero Sequence Current Transformer>oqim transformatori noto'g'ri.

Zero Sequence Current Transformer>current transformer secondary connection piece was opened during cable construction, and was not restored in time after the work was completed, resulting in open circuit of current transformer>oqim transformatorining ikkilamchi lasan.

Kabelning metall qobig'ining topraklama simining topraklama uchi terminallar bilan payvandlanmagan, shuningdek, kalit kabinasida o'rnatilgan topraklama mis novda bilan bog'lanmagan, lekin tasodifiy kalit kabinasining murvatlariga o'ralgan.
