SF6 dead‑tank circuit‑breaker, voltage range 11‑550kV, rated current 1600‑5000A, short‑circuit breaking current 25‑63kA, self‑blast arc‑extinguishing, spring‑operated mechanism for outdoor substation.
This 2026‑version PDF product manual serves for tendering, equipment selection, substation engineering design and on‑site installation‑maintenance reference.
The equipment complies with IEC 62271‑100, GB/T 1984 and related CEI, JB, DL standards. This manual explains self‑blast arc‑extinguishing operating principle, single‑/three‑phase post‑type porcelain‑insulator structure, dual‑seal flange design and pointer‑type density relay for gas condition monitoring.
It lists complete performance indicators including partial discharge value, SF₆ alarm‑blocking pressure, allowable gas moisture content, annual gas leakage rate ≤0.5%, mechanical endurance up to 10000 operations, special reclosing duty O‑0.3s‑CO‑180s‑CO and full set of timing parameters.
It defines service environmental conditions covering ‑40℃~+55℃ ambient temperature, maximum installation altitude of 3000 m and seismic resistance up to 9‑degree intensity, and provides outline dimension drawings, power‑supply requirements for heater, energy‑storage motor and control circuit, after‑sales service instructions. Custom‑built design, assembly and testing solutions are available. P

230-252kV Dead-Tank SF6 Breaker: 9-degree seismic, ≤1% leakage. High-reliability for 220kV+ grids & new energy bases.
420kV Dead Tank SF6 Circuit Breaker provides high reliability and fast arc extinction for stable grid operation with a robust design.
Dead Tank SF6 Circuit Breaker (550kV) offers high performance and reliable arc interruption. Its robust design ensures stability for ultra high voltage systems.
Gas SF6 dapat mencair pada suhu yang sangat rendah, yang akan menurunkan kinerja pemadaman busur. Tindakan teknis yang sesuai harus diterapkan untuk proyek di daerah beriklim dingin. Silakan hubungi kami untuk solusi suhu rendah.
Perhatikan rentang suhu ambien, persyaratan penurunan kapasitas pada ketinggian, intensitas seismik, dan kelas kontaminasi ambien. Modifikasi khusus diperlukan di luar kondisi standar. Silakan hubungi kami untuk saran adaptasi lingkungan.
Desain segel ganda memisahkan cincin luar tahan air dan cincin dalam tahan gas, secara efektif mengurangi kebocoran gas SF6 dan meningkatkan kemampuan beradaptasi dengan lingkungan luar ruangan. Silakan hubungi kami untuk referensi gambar struktur.
