RHD‑245 SF6 dead‑tank circuit breaker, 245kV, rated current 3150‑5000A, short‑circuit breaking current 40‑63kA, self‑blast arc‑extinguishing, three‑phase SF6 gas insulated high‑voltage circuit‑breaker.
This product flyer acts as technical reference for high‑voltage SF6 dead‑tank circuit‑breaker, supporting tender drafting, transmission substation project evaluation and pre‑sales technical review.
The product complies with IEC 62271‑100 and GB/T 1984 standards. This datasheet covers full set of technical indicators including lightning impulse and one‑minute power‑frequency withstand voltage, specified creepage distance range, partial discharge requirement, SF₆ alarm‑block pressure threshold, gas moisture limit, annual gas leakage rate, mechanical endurance and special reclosing operation sequence O‑0.3s‑CO‑180s‑CO.
It features three‑phase post‑porcelain‑insulator structure and pointer‑type density relays for continuous SF6 gas pressure and density supervision. The document also defines power supply parameters for heater, energy‑store motor and control circuit, as well as first‑open‑pole factor, cable‑line charging breaking capacity and time‑related switching performance parameters.
Custom‑made solutions including design, assembly and factory test are available for EPC projects. Please contact us for complete type‑test reports and full operation‑maintenance manuals.

Waktu buka dan tutup mencerminkan kecepatan respons mekanisme, yang secara langsung memengaruhi kecepatan pembersihan gangguan dan kondisi pemulihan transien jaringan. Silakan hubungi kami untuk materi analisis urutan waktu.
Sinyal aktif ketika densitas gas SF6 turun ke ambang batas yang telah ditetapkan. Alarm mengingatkan operator untuk melakukan pengisian gas; pemblokiran melarang operasi pensakelaran untuk mencegah kegagalan isolasi internal. Silakan hubungi kami untuk referensi pengaturan.
Tata letak terintegrasi tiga fase mengoptimalkan luas tapak keseluruhan, mengurangi penggunaan ruang fondasi, dan menyederhanakan pekerjaan pengkabelan di lokasi dibandingkan dengan solusi terpisah satu fase. Silakan hubungi kami untuk detail perbandingan tata letak.
