Abstract
Abstract Each section of a three-phase metal-enclosed switchgear unit is provided with main through horizontal bus and generally S-shaped vertical risers or section bus. The S-shaped vertically extending risers are connected to the horizontal main through bus and feed circuit breakers or other branch bus circuit controlling devices, mounted in the switchgear unit. The S-shaped vertical section bus provides a flat surface facing the front of the switchgear unit to which circuit controlling devices can easily be mounted, and also provides a flat surface facing the rear of the switchboard section for easy connection to the main through horizontal bus.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
204 words
A metal-enclosed switchgear unit, comprising: a generally rectangular section structure; three horizontally extending main through bus bar conductors disposed horizontally in a spaced apart relationship in said rectangular section; three vertical risers disposed in said rectangular section in front of said main horizontal through bus; connector means electrically connecting each phase of said horizontal main through bus to its associated vertical riser; and each of said vertical risers comprising a front flat surface facing the front of said switchgear unit, a first rearwardly extending rectangular bus member extending rearwardly in close proximity to one end of said flat surface, a middle flat surface member in front-to-back alignment with said front flat surface extending in close proximity to the rearward edge of said first rectangular bus member, a second rearward extending rectangular bus member extending in close proximity to the edge of said middle flat surface member opposite said first rearward extending surface and extending in a generally rearward direction perpendicular to said middle flat surface, and a rear flat surface member aligned with said front flat surface and said middle flat surface facing the rear of said switchgear unit and extending in close proximity to the back edge of said second rectangular bus member.
Claim 2
Dependent Claim
204 words
A metal-enclosed switchgear unit, comprising: a generally rectangular section structure; three horizontally extending main through bus bar conductors disposed horizontally in a spaced apart relationship in said rectangular section; three vertical risers disposed in said rectangular section in front of said main horizontal through bus; connector means electrically connecting each phase of said horizontal main through bus to its associated vertical riser; and each of said vertical risers comprising a front flat surface facing the front of said switchgear unit, a first rearwardly extending rectangular bus member extending rearwardly in close proximity to one end of said flat surface, a middle flat surface member in front-to-back alignment with said front flat surface extending in close proximity to the rearward edge of said first rectangular bus member, a second rearward extending rectangular bus member extending in close proximity to the edge of said middle flat surface member opposite said first rearward extending surface and extending in a generally rearward direction perpendicular to said middle flat surface, and a rear flat surface member aligned with said front flat surface and said middle flat surface facing the rear of said switchgear unit and extending in close proximity to the back edge of said second rectangular bus member.
Claim 3
Dependent Claim
46 words
A metal-enclosed switchgear unit as claimed in claim 1, wherein: a plurality of enclosures for housing circuit breakers are formed in the front of said rectangular section; and a plurality of electrical devices are supported in said enclosures and are electrically connected to said vertical risers.
Claim 4
Dependent Claim
97 words
A metal-enclosed switchgear unit as claimed in claim 1, wherein: said connector means comprises a rectangular tubular bus member being disposed between said horizontal through bus and said vertical section bus; said rectangular tubular bus member is disposed with the longitudinal axis extending in a generally vertical direction with one side engaging said horizontal through bus and the opposite side engaging said rear flat surface member of said vertical section bus; and fastening means is provided to force said vertical section bus and said horizontal through bus into high pressure engagement with said rectangular tubular bus member.
Claim 5
Dependent Claim
35 words
A metal-enclosed switchgear unit as claimed in claim 1 wherein said front flat surface of said vertical section bus has a plurality of evenly spaced holeS formed therein facing the front of said switchgear unit.
Claim 6
Dependent Claim
30 words
A metal-enclosed switchgear unit as claimed in claim 4 wherein the length of said connector means is equal to the width of said horizontally extending main through bus bar conductors.
Claim 7
Dependent Claim
45 words
A metal-enclosed switchgear unit, comprising: a structural frame; multiple through bus conductors mounted in said structural frame; multiple vertical risers disposed in said structural frame and electrically connected to said multiple through bus conductors; and each of said vertical risers comprising a generally S-shaped conductor.
Claim 8
Dependent Claim
45 words
A metal-enclosed switchgear unit, comprising: a structural frame; multiple through bus conductors mounted in said structural frame; multiple vertical risers disposed in said structural frame and electrically connected to said multiple through bus conductors; and each of said vertical risers comprising a generally S-shaped conductor.
