Abstract
The utility model discloses a capacitor cover plate assembly. The capacitor cover plate assembly comprises a cover plate, three insulating bases, wiring terminals, an insulating flat plate, an explosion-proof paperboard, a seal washer and three explosion-proof bolts. The three insulating bases are arranged on the insulating flat plate, and the insulating flat plate is arranged on the right side of the cover plate, and the explosion-proof paperboard and the seal washer are arranged on the back side of the cover plate. The explosion-proof paperboard is attached to the cover plate, the seal washer, the explosion-proof paperboard, the cover plate, the insulating flat plate and the three insulating bases are connected in series and positioned mutually and orderly via the three explosion-proof bolts. The three insulating bases are equipped with the wiring terminals, the wiring terminals are connected with the explosion-proof bolts, and the right side of the insulating flat plate is equipped with vertical baffles for separating any two adjacent wiring terminals. The capacitor cover plate assembly of the utility model effectively avoids that arc which damages contacts seriously and enables the time of a turn-off circuit to be prolonged is formed between the wiring terminals due to the excessive voltage during the working process, and has the advantages of simple structure, good sealing performance and high working efficiency.
