Abstract:
A high-voltage feedthrough capacitor comprising:a grounding member having two through-holes spaced away from each other; two feedthrough capacitor devices each comprising a central conductor, a dielectric layer, and an electrode, a periphery of said central conductor being covered with said dielectric layer, a surface of said dielectric layer being covered with said electrode, each of said feedthrough capacitor devices extending through a respective one of said through-holes and being fitted to said grounding member, each electrode being bonded to said grounding member; and an armoring insulator covering peripheries of said feedthrough capacitor devices and a periphery of said grounding member, wherein each of said two electrodes comprise a conductive thermoplastic resin, each of said dielectric layers further includes a projecting dielectric portion at one end thereof and respectively extending over said electrodes to prevent dielectric breakdown between said electrodes and said central conductors at an interface between said armoring insulator and said dielectric layers.
