Switchgear spout design

摘要

A spout assembly is provided. The spout assembly includes a spout and a spout base. The spout base has a cross-sectional area that is smaller than a spout sized to enclose an electrical switching apparatus electrical coupling. That is, the spout base includes a CT support surface with a cross-sectional area that is smaller than the spout cross-sectional area. Current transformers are disposed upon the spout base CT support surface.

主权项

1. A spout assembly for an electrical switching apparatus, said electrical switching apparatus including an electrical coupling having a cross-sectional area, said spout assembly comprising:
a spout including a generally hollow body with a first end, a second end, and a mounting, said spout body having a first cross-sectional area, said spout body mounting disposed at said spout body second end; a spout base including a body with a first end, a second end, a mounting, and a CT support surface, said spout base body CT support surface having a second cross-sectional area, said spout base body mounting disposed at said spout body first end; said first cross-sectional area sized to enclose said electrical switching apparatus electrical coupling; wherein said second cross-sectional area is substantially smaller than said first cross-sectional area; said spout body mounting coupled to said spout base body mounting; a conductor assembly, said conductor assembly having a number of conductive bodies extending through said spout body and said spout base body; and said spout base body CT support surface structured to support a number of current transformers.
