    摘要: Dielectric fluids are disclosed which comprise about 20 to 95% of a non-halogenated organic ester which is liquid between -20.degree. C. and 150.degree. C. and which has a dissipation factor of less than about 10% at 100.degree. C., and about 5% to 80% of a non-halogenated, aromatic hydrocarbon or ether, which is soluble in the ester, has 1 to 2 rings, and has a dissipation factor of less than about 10% at 100.degree. C. The preferred dielectric fluid is about 75 to 90% diisononyl phthalate and about 10 to 25% diphenyl oxide. An anti-oxidant and/or an additive to resist the effects of corona (partial discharges) are preferably included in the dielectric fluid. A capacitor containing a paper, film, or composite of these, impregnated with the dielectric fluid, is also disclosed.

    摘要: A low-voltage, low-inductance device for storing electrical charge in a snubber circuit and a method of minimizing inductance in the snubber circuit using the device, wherein the device includes a plurality of extended electrodes, in parallel or series, that are joined to a positive conductor terminal at one end spray and at a negative conductor terminal at the other end spray so that end sprays of adjacent extended electrodes are alternately joined to the positive and negative conductor terminals. Accordingly, current flowing though adjacent extended electrodes is of substantially equal intensity but different in direction. As a result, inductance produced effectively cancels out that of adjacent extended electrodes.

    摘要: A capacitor module having a solid dielectric is cleared in a gaseous environment having an electric strength greater than that of air at a pressure of one atmosphere. A plurality of such cleared capacitor modules is formed into a stack which itself is then cleared by the same clearing process. During intended operation in an electric circuit, the capacitor arrangement would be maintained in such gaseous environment having an electric strength greater than that of air at a pressure of one atmosphere.

    摘要: A capacitor is disclosed of alternating layers of plastic film and metal foil impregnated with a dielectric fluid which is an ester of a benzene tri- or tetracarboxylic acid. The esters are preferably trimellitic acid esters, especially tri-isodecyl-trimellitate. The dielectric fluid is sufficiently non-flammable to meet safety requirements and has a relatively high dielectric constant and low power factor.

    摘要: There is disclosed herein a high voltage and high temperature power electronics capacitor which comprises one or more insulator layers of mica paper, and one or more metal conductor layers, all dispersed in a pressurized environment of a nonreactive and high voltage strength gas maintained at near ambient to about 405.2 kPa of pressure. The insulator and conductor layers are isolated and separated from one another by the alternating placement of conductor layers between said insulator layers. These capacitors are readily packaged for commercial use in containers or housings of almost any geometric form and any material of construction. Moreover, low inductance ceramic bushings can be employed on these containers for establishing external electrical contacts. These capacitors can be economically manufactured and used in large commercial volumes with currently available materials and production methods.
