252kV- GIS

Document description

RHG‑252 modular GIS, double‑seal‑ring flange with annual leakage ≤0.1 %, excellent partial‑discharge index, 10 000 breaker mechanical operations, compact bay dimension, harsh‑environment resistant, IEC 61850 online‑monitoring & one‑key sequence‑control. KEMA type‑tested, insulation designed per IEC 62271‑1.

Frequently asked questions

What are partial‑discharge and SF₆ gas‑tightness performance indicators?

At 80 % rated power‑frequency voltage, full‑bay partial discharge ≤3 pC, single insulator ≤2 pC. Butt‑flange double‑seal‑ring design achieves annual SF₆ leakage rate ≤0.1 %.

What are structure layout, bay dimension and space‑saving features?

Main busbar adopts three‑phase common‑enclosure while other compartments use single‑phase enclosure. Standard bay width 2 m, minimum 1.8 m, saving land for space‑constrained substation sites.

What smart‑monitoring and factory‑test provisions are available?

Built‑in sensors support IEC 61850 online‑monitoring for gas density, micro‑moisture, partial discharge and breaker mechanical features plus one‑key sequence‑control. Every unit completes factory routine tests including lightning‑impulse withstand before delivery.
