Novel three-terminal cylindrical capacitor

The utility model relates to a three-terminal cylindrical capacitor which comprises terminals, a capacitor casing, a top cover and anti-explosion blocks. The three terminals are installed on the top cover of the capacitor, the top cover is installed on a cylindrical surface of the capacitor casing, and the anti-explosion blocks are located inside the terminals. The height of the terminals is increased by 10-20mm, and the shape of anti-explosion blocks is changed from a spherical shape to a dumbbell shape. The three-terminal cylindrical capacitor has the advantages that the defects that existing cylindrical capacitors are short in insulation distances among phases and among terminals and the casing and are easy to short circuit are eliminated and the anti-explosion effect of the capacitor is improved simultaneously.
