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)
Claims6
A power capacitor, comprising:
- a plurality of parallel-connected strings of capacitor elements, each string comprising a plurality of series-connected capacitor elements, each said capacitor elements having a pair of electrodes, and each said string including first and second end points, the respective first and second end points of each said string being respectively interconnected to form the plurality of parallel-connected strings;
- and
- said capacitor elements each having the property that, upon an electrical breakdown of a capacitor element, the pair of electrodes of the capacitor element are welded together to form a short circuit of the faulty capacitor element.
