TELECOMMUNICATIONS EQUIPMENT CABINETS INCLUDING ISOLATED AND REMOVABLE BATTERY BOX ASSEMBLIES
Example telecommunications equipment cabinets include a cabinet housing, and at least one equipment chamber defined within the cabinet housing. The equipment chamber has one or more electrical components disposed therein. The telecommunications equipment cabinet also includes a battery box removably positioned in the cabinet housing. The battery box includes at least one battery, and the battery box is isolated from the equipment chamber to inhibit hydrogen gas from escaping the battery box into the at least one equipment chamber. Associated methods of exchanging components in a telecommunications equipment cabinet are also disclosed.
1 . A telecommunications equipment cabinet comprising:
a cabinet housing;
at least one equipment chamber defined within the cabinet housing, the at least one equipment chamber having one or more electrical components disposed therein; and
a battery box removably positioned in the cabinet housing, the battery box including at least one battery, the battery box isolated from the at least one equipment chamber to inhibit hydrogen gas from escaping the battery box into the at least one equipment chamber.
2 . The telecommunications electrical equipment cabinet of claim 1 , wherein the battery box is a first battery box, the equipment cabinet further comprising a second battery box, the second battery box removably positioned in the cabinet housing and isolated from the equipment chamber to inhibit hydrogen gas from escaping the battery box into the at least one equipment chamber.
3 . The telecommunications equipment cabinet of claim 2 , wherein the first battery box and the second battery box each define one or more openings to allow air flow between the first battery box and the second battery box.
4 . The telecommunications cabinet of claim 1 , wherein:
the battery box defines an opening, the opening having a perimeter; and
the cabinet housing contacts the perimeter of the opening to facilitate isolation of the battery box from the at least one equipment chamber.
5 . The telecommunications equipment cabinet of claim 4 , wherein the cabinet housing includes a vent positioned within the perimeter of the opening of the battery box to vent hydrogen gas from the battery box.
6 . The telecommunications equipment cabinet of claim 5 , wherein the cabinet housing includes a water guard positioned adjacent the vent to inhibit water entry into the cabinet housing via the vent.
7 . The telecommunications equipment cabinet of claim 5 , further comprising:
a drip pan positioned to collect water that enters the cabinet housing through the vent; and
a drip tube connected with the drip pan to drain water collected by the drip pan out of the cabinet housing.
8 . The telecommunications equipment cabinet of claim 4 , wherein the cabinet housing includes a strip gasket corresponding to the perimeter of the opening of the battery box to seal the perimeter of the opening of the battery box.
9 . The telecommunications equipment cabinet of claim 4 , wherein:
the cabinet housing includes a cabinet door; and
the cabinet door contacts the perimeter of the opening when the cabinet door is in a closed position to facilitate isolation of the battery box from the at least one equipment chamber.
10 . The telecommunications equipment cabinet of claim 1 , wherein the battery box is removable from the cabinet housing without moving any of the one or more electrical components disposed in the at least one equipment chamber.
11 . The telecommunications equipment cabinet of claim 1 , wherein:
the cabinet housing includes an internal frame or an external frame; and
the battery box is removably coupled to the internal frame or the external frame via machine bolts.
12 . The telecommunications equipment cabinet of claim 1 , further comprising at last one of an air conditioner, a heat exchanger, and a thermoelectric cooler (TEC) positioned on the cabinet housing to reduce heat in the equipment chamber.
13 . The telecommunications equipment cabinet of claim 1 , wherein the one or more electrical components include telecommunications equipment.
14 . The telecommunications equipment cabinet of claim 1 , wherein the at least one battery includes a valve-regulated lead-acid (VRLA) battery or a SAFT battery.
15 . The telecommunications equipment cabinet of claim 1 , wherein:
the battery box includes multiple walls that are riveted or bolted together; and
seams between the multiple walls are sealed with an adhesive silicone.
16 . The telecommunications equipment cabinet of claim 1 , wherein the battery box includes multiple walls that are welded together.
17 . The telecommunications equipment cabinet of claim 1 , wherein the battery box includes a one-piece die-cast box.
18 . A telecommunications equipment cabinet comprising:
a cabinet housing having multiple vents;
at least one equipment chamber defined within the cabinet housing, the at least one equipment chamber having one or more electrical components disposed therein; and
multiple battery boxes removably positioned in the cabinet housing, each battery box including at least one battery, each battery box vented through a distinct one of the multiple vents of the cabinet housing to inhibit hydrogen gas from escaping said battery box into the at least one equipment chamber.
19 . The telecommunications cabinet of claim 18 , wherein:
each battery box defines an opening, the opening having a perimeter; and
the cabinet housing contacts the perimeters of the openings of each battery box to facilitate isolation of the battery boxes from the equipment chamber.
20 . A method of exchanging components in a telecommunications equipment cabinet, the telecommunications cabinet including at least one equipment chamber defined within the cabinet housing and multiple battery boxes positioned in the cabinet housing, the at least one equipment chamber having one or more electrical components disposed therein, each battery box including at least one battery, each battery box isolated from the at least one equipment chamber to inhibit hydrogen gas from escaping the battery box into the at least one equipment chamber, the method comprising:
removing one of the multiple battery boxes from the cabinet housing to define a space previously occupied by said one of the multiple battery boxes; and
inserting another electrical component into the space previously occupied by said one of the multiple battery boxes while maintaining isolation between the inserted electrical component and the other battery box(es) remaining in the cabinet housing to inhibit hydrogen gas from escaping the other battery box(es) to the inserted electrical component.
