  • High voltage feedthrough for non-thermal plasma reactor
    Patent number: 6368451
    Abstract: High voltage feedthrough connectors provide a means for isolating high voltage through a reactor housing while providing thermal expansion tolerance along with ease of assembly. The connectors provide an insulating body having a bore extending axially through said insulating body for housing a center conductor, a threaded shell assembly for engaging the insulating body and securing the insulating body to a NTP reactor housing, and a gas tight seal to prevent gas leaks to the center conductor. The center conductor includes a first end for contacting a high voltage source and a second end for contacting a high voltage electrode of a NTP reactor. In one embodiment, a fixed center conductor is provided. Preferably, a dome shaped tip may be provided on the bottom terminal connector for improved contact with the non-thermal plasma reactor high voltage electrode. Optionally, a compression spring is attached to the bottom terminal connector end of the fixed center conductor.
