Abstract
Abstract An integrated bushing well assembly for a transformer enclosure having a first conductor portion disposed on a first axis and extending interiorly of the transformer enclosure for connection to the transformer coil, at least two other conductor portions disposed on respective second and third axes and extending exteriorly of the transformer enclosure for connection to respective separable terminators, and an insulating housing for supporting the conductor portions with respect to the enclosure.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
181 words
For a transformer having an enclosure, a bushing well comprising a. conductor means having 1. a first conductor disposed on a first axis for connection to said transformer, 2. a second conductor disposed on a second axis for connection to a first terminator means and extending outwardly of said enclosure, 3. a third conductor disposed on a third axis for connection to a second terminator means and extending outwardly of said enclosure, 4. a fourth conductor attached to said first conductor and being disposed between and connected to said second and third conductors, 5. said three axes being disposed so that they are nonintersecting and so that no plane may be defined which contains any two of said axes, 6. at least one of said second and third axes being inclined at two angles with respect to said first axis with each of said two angles being defined in respective orthogonal projections, and b. insulating means connected to said first, second, third and fourth conductors for supporting said conductor means relative to said enclosure and for insulating said conductor means therefrom.
Claim 2
Dependent Claim
181 words
For a transformer having an enclosure, a bushing well comprising a. conductor means having 1. a first conductor disposed on a first axis for connection to said transformer, 2. a second conductor disposed on a second axis for connection to a first terminator means and extending outwardly of said enclosure, 3. a third conductor disposed on a third axis for connection to a second terminator means and extending outwardly of said enclosure, 4. a fourth conductor attached to said first conductor and being disposed between and connected to said second and third conductors, 5. said three axes being disposed so that they are nonintersecting and so that no plane may be defined which contains any two of said axes, 6. at least one of said second and third axes being inclined at two angles with respect to said first axis with each of said two angles being defined in respective orthogonal projections, and b. insulating means connected to said first, second, third and fourth conductors for supporting said conductor means relative to said enclosure and for insulating said conductor means therefrom.
Claim 3
Dependent Claim
21 words
a second conductor disposed on a second axis for connection to a first terminator means and extending outwardly of said enclosure,
Claim 4
Dependent Claim
21 words

Claim 11
Dependent Claim
59 words
A bushing well according to claim 1 wherein said insulating means has a first portion surrounding said first conductor and second and third portions surrounding said second and third conductors with said second and third portions joining said first portion so as to define a shoulder for cooperation with said enclosure to provide a fluid seal with said enclosure.
Claim 12
Dependent Claim
38 words
A bushing well according to claim 1 wherein both of said second and third axes are inclined at two angles with respect to said first axis with each of said two angles being defined in respective orthogonal projections.
