Description

Technical Field

[0002] With the development of the power industry, C-GIS gas-filled cabinets are widely used in large and medium-sized substations, industrial and mining, railways, wind power, photovoltaic and other projects due to their small size, compact structure, full insulation, safe and reliable operation, etc. The main circuit of the C-GIS gas-filled cabinet is sealed inside the gas box. Due to the small size of the C-GIS gas-filled cabinet, the heat generated by the main circuit of the C-GIS gas-filled cabinet is difficult to effectively dissipate from the sealed gas box to the external space, resulting in heat accumulation inside the gas box. Excessive temperature will cause the insulation material in the gas box to age, reduce the insulation performance, and affect the overall safe operation of the switchgear.
