36kV oil-immersed voltage regulator: 33-34.5kV, normal current depends on capacity; lightning impulse 200kV, short-time fault current 14.2kA per IEC 60076-5, making capability per transformer standards. For overhead radial/open-ring feeder regulation.
This oil‑immersed voltage regulator adopts ONAN cooling, on‑load tap‑changer with battery backup, Auto‑Local‑Manual operation mode and comprehensive alarm signal outputs. It complies with IEC 60076‑1/5/7/10/21, IEC 60137 and other standards, suitable for C5 high atmospheric corrosivity environment.
Pole - Mounted Single - phase Step Voltage RegulatorVoltage stabilization and compensation overhead voltage regulator 6kV 6.35kV 11kV 15kV 22kV 33kV single phase – IEEE C57.12 for Power Industry
32-step fully automated maintenance-free voltage regulator for 11kV to 33kV, ensuring precise voltage control with long-term reliability.
Pendinginan ONAN (minyak alami, udara alami). Kenaikan suhu minyak di bagian atas ≤50 K, kenaikan suhu rata-rata belitan ≤55 K pada kondisi MCR pengenal. Kelas isolasi adalah Kelas-A.
Catu daya bantu utama 230V AC; bank baterai 2×12V-60AH dengan inverter untuk cadangan 30 menit. Saat terjadi kegagalan suplai listrik, pengubah tap secara otomatis kembali ke posisi nol; peralihan otomatis antara daya utama dan cadangan disediakan.
Mendukung pemilih Otomatis-Lokal-Manual, operasi engkol manual. Sinyal meliputi posisi tap, perubahan tap sedang berlangsung, perubahan tap tidak selesai, out-of-step, kegagalan suplai, penghitung, serta berbagai sinyal alarm dan trip suhu/tekanan/Buchholz.
