Abstract

A switchgear/board cabinet is constructed using a dual compartment module ( 100 ) that includes an equipment compartment ( 200 ) and a bus compartment ( 300 ) arranged behind the equipment compartment. The bus compartment includes line connection buses ( 310 ) and load connection buses ( 320 ) for a plurality of phases, spaced-apart vertical interphase barriers ( 330 ), a horizontal support barrier ( 340 ) and a rear barrier ( 350 ) forming a back wall. Each of the vertical interphase barriers extends from a front to a back of the bus compartment, and isolates the load connection bus and line connection bus of each phase from the load connection bus and line connection bus of the other of the phases. The horizontal support barrier extends from the front to the back of the bus compartment, and supports the line connection buses. Any number of dual compartment modules may be constructed and stacked to provide a customized switchgear/board cabinet.

First claim

The invention claimed is:

line connection buses for a plurality of phases;
load connection buses for the plurality of phases;
spaced-apart vertical interphase barriers extending from a front to a back of the bus compartment, and isolating the load connection bus and line connection bus of each of the plurality of phases from the load connection bus and line connection bus of the other of the plurality of phases; and
a first horizontal support barrier extending from the front to the back of the bus compartment, and supporting each of the line connection buses, the first horizontal support barrier having one or more openings through which to electrically connect the line connection buses to corresponding line connection buses of another dual compartment module.

2. The method according to claim 1 , further comprising:
constructing another of the dual compartment module; and
stacking one of the dual compartment modules on top of the other of the dual compartment modules.

3. The method according to claim 2 , wherein stacking comprises:
engaging an offset at a bottom portion of one of the dual compartment modules to a top portion of the other of the dual compartment modules.

4. The method according to claim 1 , wherein constructing a dual compartment module comprises:
forming opposite side walls of the bus compartment with two of the vertical interphase barriers.

5. The method according to claim 1 , wherein constructing a dual compartment module comprises:
engaging the first horizontal support barrier into a slot of each of the vertical interphase barriers.

6. The method according to claim 1 , wherein constructing a dual compartment module comprises:
constructing a line connection bus for each of the plurality of phases to include a vertical riser and a horizontal bus having one end for connecting to switching equipment in the equipment compartment and a second end for connecting to the vertical riser.

7. The method according to claim 6 , wherein the plurality of phases comprises three phases, and the vertical risers of the three phases are aligned in a triangular orientation in the bus compartment.

8. The method according to claim 1 , wherein constructing a dual compartment module comprises:
engaging an end of each load connection bus through corresponding slots in the rear barrier of the bus compartment.

9. The method according to claim 1 , wherein constructing a dual compartment module comprises:
providing a window in the rear barrier to access a line connection bus for one of the plurality of phases in the bus compartment; and
securing a removable cover to the window.

10. The method according to claim 1 , wherein constructing a dual compartment module comprises:
providing a base support plate in the equipment compartment, the base support plate having a front end extending downward, the front end including a plurality of spaced-apart holes for engaging corresponding vent pipes arranged below the base support plate.

11. The method according to claim 1 , further comprising:
housing a breaker in the equipment compartment.

12. A method of constructing a switchgear/board cabinet, the method comprising:
