Higher Power
Our a number of pin feedthroughs include multiple conductors and are sealed either by insulating the pins from the casing utilizing person pieces of glass or, using a single piece of glass with numerous sealing holes. Every pin bore (78) has a pin bore (78) size higher than the feedthrough pin (80) size, preferably by an quantity no greater than that essential to permit the penetration of a brazing metal (88) in between the pin bore (78) and the feedthrough pin (80).
DESCRIPTION OF AN EMBODIMENT Referring to thedrawing, there is shown in the FIG- URE a higher-voltage feedthrough assembly ten which types a sealed atmosphere-vacuum interface in a metal wall 12 of a vacuum enclosure and gives an insulated conduction path for passing higher voltages more than a cable 14 into the vacuum space within the enclosure.
The furnace brazing strategy, jigging for it, and metalizing of ceramic surfaces for brazing straight thereto are described and referenced in that patent, and such identified processes and strategies are fully applicable to the device of the present invention.
As transmission line voltages reached and passed 60,000 volts, the insulators needed turn out to be quite massive and heavy, with insulators produced for a safety margin of 88,000 volts getting about the sensible limit for manufacturing and installation.
To ensure the braze material adheres securely, Morgan Advanced Ceramics employs a method known as "sputtering," in which the surface of the ceramic is ready for brazing by the application of a thin film of biocompatible metal, via physical vapor deposition (PVD).
UMEK LLC Some approaches which have been employed in the previous contain incapsulation exactly where the feed-thru pin or conductor or terminal is held in position and sealed to its housing or support structure via the use of a appropriate incapsulant such as an epoxide, a thermoset plastic material, a thermoplastic material or a silicone sealer or the like.
The conductors 2 of the present inlet are placed in the double wall of an electrical insulating tube 406, at the reduced portion of which there is cryogenic fluid 5 surmounted by its vapors six. The conductors three of the the present output leads are likewise arranged in the double wall of an electrical insulating tube 407. UMEK.PRO
