摘要： A capacitor system is disclosed that includes a first capacitor with a connection for a first pole and a connection for a second pole and a second capacitor with a connection for a first pole and a connection for a second pole. The first poles are like poles in relation to one another and the second poles are like poles in relation to one another and the first poles are of a polarity different from the second poles. Two different-polarity connections of two capacitors are connected to the capacitors on one side of the capacitor system and lead out from the capacitor system at a substantially constant distance from one another, in parallel and/or in a twisted state.

摘要： A microcapacitor array for providing artificial muscles is described. The microcapacitor array includes a dielectric body with electrode chambers, positive electrodes in positive electrode chambers, the positive electrodes being connected by a first set of channels in the dielectric frame; negative electrodes in negative electrode chambers, the negative electrodes being connected by a second set of channels in the dielectric frame. The first and second set of channels are arranged so that application of a voltage differential between the positive electrodes and the negative electrodes generates an attractive force between each set of adjacent positive and negative electrodes.

摘要： A capacitor provides a plurality of selectable capacitance values, by selective connection of six capacitor sections of a capacitive element each having a capacitance value. The capacitor sections are provided in a plurality of wound cylindrical capacitive elements. Two vertically stacked wound cylindrical capacitance elements may each provide three capacitor sections. There may be six separately wound cylindrical capacitive elements each providing a capacitor section. The capacitor sections have a common element terminal. A pressure interrupter cover assembly is sealingly secured to the open end of case for the elements and has a deformable cover with a centrally mounted common cover terminal and a plurality of section cover terminals mounted at spaced apart locations. A conductor frangibly connects the common element terminal of the capacitor section to the common cover terminal and conductors respectively frangibly connect the capacitor section terminals to the section cover terminals. Deformation of the cover caused by failure of the capacitor element breaks at least some of the frangible connections sufficient to disconnect the capacitive element from an electric circuit in which it is connected. A cover insulation barrier mounted on the deformable cover, has a barrier cup substantially surrounding the common cover terminal and a plurality of barrier fins each extending radially outwardly from the barrier cup, and deployed between adjacent section cover terminals.

摘要： A vacuum variable capacitor includes a pre-vacuum enclosure for reducing a pressure differential across the bellows, wherein a drive is disposed outside the enclosures of the vacuum variable capacitor. The vacuum force load on the drive system can thereby be reduced, allowing faster movement of the movable electrode, faster capacitance adjustment of the vacuum variable capacitor and longer lifetimes of the device.
