Shell deformation

Because the dielectric inside the capacitor is dissociated under the action of the high voltage electric field, the medium will decompose and precipitate gas, or because of the breakdown of some components, the discharge of the capacitor pole to the shell will cause the medium to precipitate the gas. These gas in sealed housing will cause the internal pressure to increase and thus cause the shell to expand and deform. Therefore, the deformation of the capacitor shell is a sign of the fault or failure of the capacitor.
