Oil Level Window Improvement of Capacitor Voltage Transformer

Capacitor voltage transformer is an important power equipment in substation, which is with great significance to the safe operation of substation. This paper summarizes and analyzes the common problems in the process of technical supervision of capacitor voltage transformer, and the oil level window of electromagnetic unit is improved to avoid the disadvantage of oil level inspection inconvenient of capacitor voltage transformer. Inclined angle between oil level window and electromagnetic unit is 60°. The oil level window is large, and the material with aging resistance and high transparency is selected. The problems existing in the oil level inspection of CVT electromagnetic unit are effectively solved and the safe and stable operation ability of equipment is enhanced by improving oil level window.
