RHD-145 dead-tank SF6 circuit breaker: 145kV, 2500-4000A, lightning impulse 650/750kV, 3s short-time 31.5-50kA, making peak 100-125kA. For 145kV outdoor substation primary circuits.
RHD‑145 is outdoor dead‑tank SF6 circuit breaker adopting self‑blast arc‑extinguishing principle, three‑phase post porcelain insulator and pointer density relay. It has strict requirements for foundation static/dynamic load and base flatness. It complies with IEC 62271‑100 & GB/T 1984, with custom‑manufacturing and full project solutions available.
Beban statis pondasi 23000 N; beban dinamis horizontal 4000 N, beban dinamis vertikal ke atas 33000 N (termasuk berat sendiri). Perbedaan ketinggian pondasi ≤2 mm, toleransi kerataan permukaan dasar ≤2 mm.
Ini memenuhi IEC 62271-100 dan GB/T 1984. Produk ini mengadopsi pemadam busur self-blast, isolator porselen tipe pos tiga fase, dan relai kerapatan SF6 tipe penunjuk untuk aplikasi gardu induk luar ruangan.
