Abstract
The present invention relates, in general, to an apparatus for an electrical power feedthrough suitable for use in high temperature, high pressure, and/or corrosive environments, such as, for example, within ammonia cracking (i.e., dissociation) systems. The present invention is fabricated from conductive nickel alloys which have high melting temperatures, and which are resistant to corrosion at high temperatures, as well as non-conductive ceramic materials which provide electrical insulation between the systems that feedthrough is coupled to.
Claims20
An electric feedthrough for conducting electric currents, comprising:
- a pass-thru stud having a seat located between first and second threaded distal ends;
- a first pair of nickel alloy washers disposed between a first pair of threaded nuts disposed on the first threaded distal end of the pass-thru stud;
- a plug disposed on the pass-thru stud, the plug having an aperture and a threaded portion;
- an insulating sleeve disposed within the aperture;
- a counterbore washer disposed on the pass-thru stud adjacent to the threaded portion of the plug;
- a second pair of nickel alloy washers disposed on the pass-thru stud and located within the counterbore washer;
- a first ceramic washer disposed on the pass-thru stud between the counterbore washer and the seat;
- a third pair of nickel alloy washers disposed between a second pair of threaded nuts disposed on the second threaded distal end of the pass-thru stud;
- a second ceramic washer disposed on the pass-thru stud between a pair of metallic washers;
- and
- a body disposed on the pass-thru stud, the body covering the second ceramic washer, the pair of metallic washers, the seat of the pass-thru stud, the first ceramic washer, the counterbore washer, and the second pair of nickel allow washers, wherein the body has internal threading which couples to the threaded portion of the plug.
An electric feedthrough for conducting electric currents in a high temperature, high pressure, and highly corrosive environment, comprising:
- a pass-thru stud having a seat with a first face and a second face;
- a first ceramic washer disposed on the pass-thru stud adjacent the first face of the seat;
- a counterbore washer disposed on the pass-thru stud adjacent the ceramic washer;
- a pair of washers made from an alloy of nickel containing chromium and iron located within the counterbore washer;
- a plug disposed on the pass-through stud adjacent to the counterbore washer, the plug having a threaded portion;
- a second ceramic washer located between a pair of metallic washers disposed on the pass-thru stud adjacent the second face of the seat;
- and
- a body having internal threading, the internal threading capable of coupling to the threaded portion of the plug.
