Abstract

A switchgear housing assembly includes a first switchgear housing including a cable compartment portion and a circuit breaker portion, a busbar portion, and a second switchgear housing a cable compartment section, a busbar section, and a circuit breaker section. An exhaust duct is arranged between the first and second switchgear housings. The exhaust duct is selectively fluidically exposed to at least one of the cable compartment portion, cable compartment section, the circuit breaker portion, and the circuit breaker section. A floating flap assembly is operatively associated with at least one of the first and second switchgear housings. The floating flap assembly includes a floating flap member. The floating flap member is selectively slideable between a closed position and an open position in response to a pressure rise in one of the cable compartment portion, cable compartment section, circuit breaker portion, and circuit breaker section.

First claim

What is claimed is:

1. A switchgear housing assembly comprising:
a first switchgear housing including a top wall, a bottom wall, a rear wall and first and second side walls extending between the top wall and bottom wall defining an interior portion including a cable compartment portion, a busbar portion, and at least one circuit breaker portion;
a second switchgear housing including a top wall, a bottom wall, a rear wall and first and second side walls extending between the top wall and the bottom wall defining an interior portion including a cable compartment section, a busbar section, and at least one circuit breaker section;
an exhaust duct arranged between the first and second switchgear housings, the exhaust duct being selectively fluidically exposed to at least one of the cable compartment portion, the cable compartment section, the at least one circuit breaker portion, and the at least one circuit breaker section; and
a floating flap assembly operatively associated with at least one of the first and second switchgear housings, the floating flap assembly including a floating flap member, the floating flap member being selectively slideable between a closed position and an open position without rotating relative to the switchgear housing in response to a pressure rise in one of the cable compartment portion, cable compartment section, at least one circuit breaker portion and at least one circuit breaker section.

2. A switchgear housing assembly comprising:
a first switchgear housing including a top wall, a bottom wall, a rear wall and first and second side walls extending between the top wall and bottom wall defining an interior portion including a cable compartment portion, a busbar portion, and at least one circuit breaker portion;
a second switchgear housing including a top wall, a bottom wall, a rear wall and first and second side walls extending between the top wall and the bottom wall defining an interior portion including a cable compartment section, a busbar section, and at least one circuit breaker section; and
an exhaust duct arranged between the first and second switchgear housings, the exhaust duct comprising a floating flap member arranged to selectively fluidically expose the exhaust duct to at least one of the cable compartment portion, the cable compartment section, the at least one circuit breaker portion, and the at least one circuit breaker section by sliding between a closed position and an open position without rotating relative to the exhaust duct.

3. The switchgear housing assembly according to claim 2 , wherein the at least one circuit breaker portion includes a first circuit breaker portion and a second circuit breaker portion, the second circuit breaker portion being arranged between the first circuit breaker portion and the top wall, wherein the first circuit breaker portion is selectively fluidically connected to the exhaust duct.

4. The switchgear housing assembly according to claim 3 , wherein the second circuit breaker portion is fluidically isolated from the exhaust duct.

5. A switchgear housing assembly comprising:
a switchgear housing including a top wall, a bottom wall, a rear wall and first and second side walls extending between the top wall and bottom wall defining an interior portion including a cable compartment portion, a busbar portion, and at least one circuit breaker portion; and
a floating flap assembly operatively associated with the switchgear housing, the floating flap assembly including a floating flap member, the floating flap member being selectively slideable between a closed position and an open position without rotating relative to the switchgear housing in response to a pressure rise in one of the cable compartment portion, and at least one circuit breaker portion.

6. The switchgear housing assembly according to claim 5 , wherein the floating flap assembly is mounted relative to the top wall, wherein the floating flap member is selectively shiftable longitudinally upwardly in response to the pressure rise in the one of the cable compartment portion, and at least one circuit breaker portion.

7. The switchgear housing assembly according to claim 6 , wherein the floating flap assembly includes a first guide rod and a second guide rod, the floating flap member being selectively shiftable across the first and second guide rods in response to the pressure rise in the one of the cable compartment portion, and at least one circuit breaker portion.

8. The switchgear housing assembly according to claim 7 , further comprising:
a first bearing associated with the first guide rod and a second bearing associated with the second guide rod, the first and second bearings slidingly supporting the floating flap member relative to the first and second guide rods.

9. The switchgear housing assembly according to claim 5 , wherein the floating flap assembly is mounted relative to one of the first and second side walls, wherein the floating flap member is selectively shiftable laterally outwardly in response to the pressure rise in the one of the cable compartment portion, and at least one circuit breaker portion.

10. The switchgear housing assembly according to claim 9 , wherein the floating flap assembly includes a first guide rod and a second guide rod, the floating flap member being selectively shiftable across the first and second guide rods in response to the pressure rise in the one of the cable compartment portion, and at least one circuit breaker portion.

11. The switchgear housing assembly according to claim 10 , further comprising: a first bearing associated with the first guide rod and a second bearing associated with the second guide rod, the first and second bearings slidingly supporting the floating flap member relative to the first and second guide rods.

12. The switchgear housing assembly according to claim 5 , wherein the floating flap assembly includes a body mounted relative to one of the first and second side walls of the switchgear housing, the body including a top wall section, a bottom wall section, a front wall section and a rear wall section and a divider extending between the bottom wall section and the top wall section, the divider establishing a circuit breaker exhaust portion corresponding to the circuit breaker portion and a cable compartment exhaust portion generally corresponding to the busbar portion.

13. The switchgear housing assembly according to claim 12 , wherein the floating flap member is arranged in one of the circuit breaker exhaust portion and the cable compartment exhaust portion.

14. The switchgear housing assembly according to claim 13 , wherein the floating flap member is arranged in the circuit breaker exhaust portion.

15. The switchgear housing assembly according to claim 14 , wherein the floating flap assembly further includes another floating flap member arranged in the cable compartment exhaust portion.

16. The switchgear housing assembly according to claim 13 , wherein the floating flap assembly includes a first guide rod and a second guide rod, the floating flap member being configured to selectively shift across the first and second guide rods in response to the pressure rise in the one of the cable compartment portion, and at least one circuit breaker portion.

17. The switchgear housing assembly according to claim 16 , further comprising: a first bearing associated with the first guide rod and a second bearing associated with the second guide rod, the first and second bearings slidingly supporting the floating flap member relative to the first and second guide rods.
