  • Patent number: 6370009
    Abstract: An internally-fused capacitor includes a capacitor housing, at least one capacitor module, and at least one fuse assembly. The capacitor module is positioned in the housing and includes capacitor elements. Each capacitor element includes a first extended foil edge on a first end and a second extended foil edge on a second end. The fuse assembly is positioned in the housing and includes a fuse wire. The fuse wire is connected at a first end of the fuse wire to the first extended foil edge by a crimped connection.

  • Patent number: 5097244
    Abstract: An electrical fault protective device for providing power interruption in electrical circuits rated up to 10,000 amperes and above. The device comprises a single- or double-vented expulsion-type fuse, connected at one vented end to a hollow bus and at the other end to a conductive expansion chamber for a double-vent fuse or an electrical contact for a single-vent fuse. A spring located in the hollow bus is attached to the fusible link for pulling the fusible link from the fuse tube to rapidly extinguish the arc when the fuse blows. The fuse tube is also retractable into the hollow bus when the fuse blows to provide a visual indication of fuse operation and to relieve the dielectric stress on the fuse tube.

  • Patent number: 4633369
    Abstract: A power factor correction capacitor is disclosed which includes: one generally flat elongated extended foil pack formed by wrapping a sheet of film, a wider sheet of foil, another but similar sheet of film and another but similar sheet of foil; a second generally flat elongated extended foil pack generally similar to the first pack; and at least one clip which mechanically connects one of the extended sheets of foil in the first pack with one of the extended sheets of foil in the second pack by physically piercing the extended edges of the adjacent foil ends.

  • Patent number: 4355346
    Abstract: An electrical apparatus, such as a capacitor, having an improved dielectric system. The capacitor includes alternate layers of metal foil and dielectric material which is impregnated with 1,1-bis(3,4-dimethylphenyl)ethane. The capacitor has improved corona characteristics and low dielectric losses. The liquid dielectric is biodegradable and environmentally acceptable.
