A capacitor discharge circuit constructed by a combination of a mechanical switch and an electronic switch. The electronic switch is automatically turned on with a predetermined time delay after closing of the mechanical switch. The mechanical switch is used to completely separate a high voltage-large capacity capacitor from a load when the discharge operation is not required. The wear and tear of contacts in the mechanical switch can be avoided by the delayed operation of the electronic switch.

Capacitor discharge circuit

An electrode lead tab for oil-impregnated capacitors having dielectric sheets and electrode foils laminated to each other, in which a plurality of cutting lines or rifts are provided to a tab main body, so that the tab main body can ensure a close electrical contact at a plurality of regions thereof to the electrode foils.
