The sight glass of the thin oil-sealed dry gas cabinet is used to observe the oil level, water level, and oil quality of the oil tank at the bottom of the gas cabinet. A pylon-shaped clear glass with a diameter of 200 mm is installed in the peephole. Due to the quality of the speculum glass itself, improper operation of the installation process, and collision during use, the glass of the speculum glass of some gas cabinets is often cracked, and cracks increase with time, and in this case, cracks increase. The glass of the sight glass needs to be replaced to ensure the safe operation of the gas cabinet.
