    摘要: An apparatus for detecting the onset of a potential lightning discharge condition monitors the odd harmonics of an RF signal radiated from a conductive probe (antenna) for fluctuations that are representative of an electrostatic condition-induced corona. In response to the such fluctuations, an output signal representative of the onset of said condition is generated. This output signal may be employed to decouple communication equipment from its antenna until the lightning condition has subsided. In accordance with a further aspect of the present invention, there is provided a device for discharging static charge accumulation from a moving body (e.g. an aircraft) which is comprised of at least one discharging conductive wick arranged to be affixed to the trailing edge of a wing, so that charges may flow from the aircraft into the wick and be discharged therefrom. To enhance discharging of the aircraft, a tuned (LC) circuit, resonant at a frequency within an RF spectrum of frequencies of corona discharge currents that flow through the wick, is coupled between the wing and the wick. Once the level of static charge build-up on the aircraft is sufficient to initiate corona discharge, current flow through the resonant circuit begins to self-oscillate and continues to `ring` after the D.C. voltage level on the body has dropped below that level at which corona was initiated.

    摘要: An ionic material is added to a halocarbon insulating fluid used to cool high voltage equipment in order to prevent the buildup of electrtostatically generated charge. The ionic additive allows leakage of charge from the insulating fluid so as to prevent dangerously high voltage buildup while at the same time withstanding the high voltage applied to the system.

    摘要: An electric capacitor particularly for use as a high frequency power capacitor, and provided with liquid cooling, the capacitor having separated metal layers as its plates and the metal layers being separated by a densely sintered ceramic dielectric body, one embodiment of which is generally pot-shaped. Heat generated in the capacitor is dissipated by cooling liquid which is directed by a jacket surrounding that one metal layer to pass over the metal layer and dissipate the heat. The metal layer is comprised of a silver frit. To avoid the metal layer being eroded by the cooling liquid, a layer of glaze, which is resistant to the cooling liquid and whose coefficient of expansion is similar to that of the dielectric body covers over the metal layer in contact with the cooling liquid.

    摘要: A capacitor is produced by stacking on a rod-like conductor two spaced capacitor discs separated by a metallic disc or radial element all in intimate contact, and encircling the discs with a metal retaining element in contact with the peripheries of the capacitor discs, the metal disc having a smaller diameter. The capacitor discs are formed from plastic materials such as polytetrafluoroethylene polymer or printed circuit board material or the like, clad on both sides with the cladding being removed on one side adjacent the outer periphery and on the other side adjacent a central aperture, the capacitor elements being secured in assembled relationship. A plurality of the aforesaid capacitors can be conveniently secured in stacked relationship to provide increased capacitance.

    摘要: A fluid cooled vacuum capacitor in which only a single metal bellows is required. Coolant is directed down the hollow center of the main shaft to the device and returns in a counterflow direction in the space between the shaft-bearing sleeve subassembly and the internal surface of the bellows. A unique fluid sealing arrangement includes primary and secondary shaft seals of the chevron type with circumferential expander springs and a leakage relief path between seals. Shaft bearings are metal-to-metal type and are fluid lubricated.
