Gas Insulated Switchgear (HV GIS)

Gas Insulated Switchgear의 사진 0

The SF6 Gas Insulated Switchgear (GIS) contains major substation equipment, such as the gas circuit breaker, disconnecting switch, earthing switch, voltage transformer, current transformer, and lightning arrester, within a grounded metallic enclosure filled with SF6 gas to provide the best possible insulation and arc-quenching capabilities.

ILJIN’s GIS is the most highly-developed switchgear on the market today. Our products provide features such as compact designs, safety, reliability, simplified operation, long maintenance intervals and compatibility with surrounding systems. Our recently developed 3-phase encapsulated GIS is an example of the economical and compact substation design our customers have come to know and expect from ILJIN.


[Feature & Advantage]

1) Reliability
 · A circuit breaker which surpasses the KERI and KEMA standards outlined in the latest IEC standards (IEC 62271-203 & IEC 62271-100).
 · A phase common enclosure for fewer components and no errors.
 · A high-quality circuit breaker featuring a hydraulic operating mechanism (170kV GIS) or a motor operated spring mechanism (25.8kV, 36kV, 72.5kV GIS, 145kV GIS, 245kV GIS).


2) Compact Design
 · A small and lightweight phase common enclosure design (72.5kV GIS, 145kV GIS, 170kV GIS).
 · A CT housed in the CB and a line disconnecting switch, line earthing switch, and work earthing switch contained in a single enclosure to reduce size and weight.
 · A CB motor operated spring mechanism adopted to make our GIS lighter and more compact than comparable models (25.8kV, 36kV, 72.5kV GIS, 145kV GIS, 245kV GIS).


3) Safety
 · Earthed enclosure to provide improved protection against current leakage.
 · Interlocking system to optimize system operation.


4) Modular Design
 · Standardized modules to improve production quality and allow for easy assembly.


5) Gas Tightness
 · Standardized sealing ring (O-ring) system to reduce the number of pipes and valves in each system and improve gas tightness.


6) Adoption of the Puffer & Hybrid Type Gas Circuit Breaker
 ·  Puffer & hybrid type gas circuit breaker for simplified construction, fewer components, no gas heating of components, and enhanced reliability.
