Abstract
The invention discloses a closed type depressurization capacitor which comprises a capacitor core group, a capacitor outer shell, a capacitor shell cover, a leading-out terminal, a leading wire and a decompression valve. A transverse sealing wall and a vertical sealing wall are arranged in the capacitor outer shell and divide the interior of the capacitor outer shell into an opening portion, a core group portion and a depressurization cabin. The capacitor shell cover is combined with the opening portion in a buckled mode. The leading-out terminal is fixedly arranged on the capacitor shell cover and is electrically connected with the capacitor core group through the leading wire. The capacitor core group is located at the core group portion. A chute is formed in the capacitor outer shell and is communicated with the core group portion, the depressurization cabin and the outside air. The decompression valve is arranged in the chute and is in seal fit with the chute. The closed type depressurization capacitor avoids accidents caused by breakage of the capacitor outer shell due to too large pressure in the capacitor, and prevents some toxic and harmful capacitor filling gas from being directly discharged into the air.
