RHD‑72.5 SF6 dead‑tank circuit breaker, 72.5kV, rated current 2000‑3150A, short‑circuit breaking current 31.5‑50kA, self‑blast arc‑extinguishing, three‑phase SF6 gas insulated circuit‑breaker.
This product flyer serves as technical brochure for medium‑high voltage SF6 dead‑tank circuit‑breaker, used for tender document compilation, substation project assessment and pre‑sales technical reference.
This product complies with IEC 62271‑100 and GB/T 1984 standards. The datasheet records full‑range technical parameters including lightning impulse and one‑minute power‑frequency withstand voltage, creepage distance range, partial discharge requirement, special alarm and blocking pressure setting, SF₆ gas moisture limit, annual gas leakage rate, mechanical life and reclosing duty O‑0.3s‑CO‑180s‑CO.
It adopts three‑phase post‑type porcelain insulator configuration and pointer‑type density relays for real‑time SF6 pressure and density monitoring. This document also specifies heater, energy‑store motor and control circuit power requirements, together with first‑open‑pole factor 1.5, 4‑second short‑circuit duration, line charging breaking capacity and each switching time indicator.
Customized solutions covering design, assembly and factory test are available for EPC projects. Please contact us for complete type‑test reports and full operation‑maintenance manuals.

Kompatibilitas frekuensi ganda tersedia, sementara kinerja yang relevan harus dikonfirmasi sesuai dengan frekuensi jaringan aktual di lokasi proyek. Silakan hubungi kami untuk referensi adaptasi frekuensi.
Alarm tekanan mengingatkan staf untuk menambah gas SF6 sebagai peringatan dini; tekanan pemblokiran mengunci fungsi pensakelaran untuk menghindari operasi pada tingkat isolasi yang tidak memadai. Silakan hubungi kami untuk tips komisioning di lokasi.
Faktor kutub pembuka pertama yang lebih tinggi memerlukan kinerja dielektrik yang lebih kuat untuk kutub pemutus pertama pada pembukaan kutub tidak serentak, sehingga meningkatkan kemampuan adaptasi terhadap kondisi transien jaringan yang kompleks. Silakan hubungi kami untuk penjelasan koordinasi isolasi.
