Power capacitor

Year	Description
1993	Invention patented by Natan Gothelf on October 7th, 1993. Abstract: A power capacitor (30, 40) composed of a plurality of parallel-connected strings (36) of capacitor elements (33,43), wherein each string comprises a plurality of series-connected capacitor elements, said parallel strings are interconnected at their end points only and said capacitor elements (33,43) are adapted such that, in case of a breakdown, the electrodes are welded together to achieve a solid short circuit of the faulty capacitor element. (FIG. 3)
1994	Invention patented by Eric Sebillotte and Serge Theoleyre on November 14th, 1994. Abstract: A power capacitor including at least one capacitive winding, of self-healing type, located in a case made of plastic material and coated in a polymerizable resin cast directly into the case. The capacitor includes a breaking device sensitive to an overpressure. Passage of gases in the direction of the breaking device is achieved by deformation of the plastic material constituting the case. The plastic material of the case presents predetermined mechanical strength, impact strength and thermal resistance characteristics.
1999	Invention patented by Robert Huber on March 29th, 1999. Abstract: In a power capacitor with a plurality of round, wound elements accommodated in a common housing at least one wound element group consisting of three round, wound elements is accommodated in the housing, with the wound elements of the group being arranged in star-form alongside one another, with their axes parallel to one another. The housing has in cross-section in general the shape of a triangle having rounded corners, with a radius of curvature which corresponds at least substantially to the radius of the round, wound elements.
1999	Invention patented by Thomas Lovkvist, Henri Bonhomme, and Cipriano Monni on April 1st, 1999. Abstract: A power capacitor has at least one capacitor unit, each capacitor unit formed of at least one winding, having at least two foils of insulating material, wherein the capacitor unit(s) is (are) housed in a casing of which at least the body is made of extruded aluminum, which body surrounds said capacitor unit(s).
2000	Invention patented by Harald Vetter and Ludwig Berg on October 9th, 2000. Abstract: The invention relates to a power capacitor for use in capacitor banks, which is build into a housing and interconnected by ribbon cables. The capacitor and ribbon cable are interconnected using plug-in functional elements which are mounted on the housing and into which contact arranged on the ribbon cables are inserted
