Cabinet for a high current power distribution system
View Patent ↗A power distribution system comprising a cabinet having one or more equipment envelops for holding electrical component modules therein and an interior passageway that is configured to accommodate DC vertical bus bars within the cabinet. The interior passageway is also configured such that the vertical bus bars can be positioned outside of lateral perimeters of the equipment envelops and the vertical bus bars can substantially traverse an entire interior long axis length of the cabinet.
1. A power distribution system, comprising:
a cabinet having one or more equipment envelops for holding electrical component modules therein and an interior passageway that is configured to accommodate DC vertical bus bars within the cabinet such that the vertical bus bars can be positioned outside of lateral perimeters of the equipment envelops and the vertical bus bars can substantially traverse an entire interior long axis length of the cabinet; and
the vertical bus bars positioned within the interior passageway, wherein each of the DC vertical bus bars are configured to carry a direct current of about 80 Amps or greater with an applied voltage of about 48 DC Volts, are composed of aluminum, have a thickness of at least about 0.25 inches, a short axis width of at least about 2 inches, and a long axis length equal to at least about 80 percent of a long axis length of the cabinet.
2. The power distribution system of claim 1 , wherein each of the DC vertical bus bars are configured to carry the direct current of about 80 Amps or greater over the entire long axis length of the bus bar.
3. The power distribution system of claim 1 , wherein the interior passageway is located behind the lateral perimeters of the equipment envelops.
4. The power distribution system of claim 1 , wherein one of electrical component modules includes a rectifier connected to one end of the DC vertical bus bars.
5. The power distribution system of claim 4 , wherein the cabinet further includes an AC conduit that is connected to the rectifier.
6. The power distribution system of claim 5 , wherein the rectifier is located in an upper-most one of the equipment envelops of the cabinet.
7. The power distribution system of claim 1 , wherein one of electrical component modules includes a battery connected to one end of the DC vertical bus bars.
8. The power distribution system of claim 1 , wherein one of the electrical component modules includes a rectifier connected to one end of the DC vertical bus bars and another one of electrical component modules includes a battery connected to the other end of the DC vertical bus bars.
9. A power distribution system, comprising:
a cabinet having one or more equipment envelops for holding electrical component modules therein and an interior passageway that is configured to accommodate DC vertical bus bars within the cabinet such that the vertical bus bars can be positioned outside of lateral perimeters of the equipment envelops and the vertical bus bars can substantially traverse an entire interior long axis length of the cabinet, wherein the interior passageway is located laterally adjacent to the lateral perimeters of the equipment envelops.
10. A power distribution system, comprising:
a cabinet having one or more equipment envelops for holding electrical component modules therein and an interior passageway that is configured to accommodate DC vertical bus bars within the cabinet such that the vertical bus bars can be positioned outside of lateral perimeters of the equipment envelops and the vertical bus bars can substantially traverse an entire interior long axis length of the cabinet further including at least one adapter configured to connect to one of the vertical bus bars and to one of the electrical component modules when the electrical component module is located in the equipment envelop, wherein the adaptor includes one or more over-current protection devices.
11. The power distribution system of claim 10 , wherein the over current protection devices includes one or more fuses.
12. The power distribution system of claim 10 , wherein the over current protection devices includes one or more circuit breakers.
13. The power distribution system of claim 10 , wherein one end of the adaptor is in equipment envelop and another end of the adapter is in the interior passageway.
14. The power distribution system of claim 10 , wherein the adaptor is located behind the electrical component module.
15. The power distribution system of claim 10 , wherein the adaptor is located to one of the sides of the electrical component module.
16. A method of assembling the power distribution system, comprising:
providing a cabinet having one or more equipment envelops for holding electrical component modules therein and an interior passageway that is configured to accommodate DC vertical bus bars within the cabinet such that the vertical bus bars can be positioned outside of lateral perimeters of the equipment envelops and the vertical bus bars can substantially traverse an entire interior long axis length of the cabinet;
positioning the DC vertical bus bars within the interior passageway of the cabinet such that the vertical bus bars can substantially traverse the entire interior long axis length of the cabinet;
connecting an adapter to one or more of the vertical bus bars such that the adapter breaches one of the equipment envelopes; and
inserting one or more over-current protection devices into the adapter.
17. The method of claim 16 , further including securing an electrical component module in the cabinet such that the electrical component module is within the equipment envelope and is electrically connected to the adapter.
