Development of a Cleanly Oil-filling and Pressurized Leakage Detection System for Assembling Capacitor

At present, insulation oil quality for assembling capacitor is ensured by storage and filling under vacuum. Filling compressed nitrogen or oil into the assembling capacitor is an effective means for leakage detection. The developed system has these two functions, and in combination with the oil vacuum cleaning system it can reliably guarantee the oil quality and sealing of the product.
