Path mitigation arc fault arc fault in power supply housing

摘要

Housing (200; 700) for a power supply, comprising: a first compartment (201; 400; 701B); a second compartment (202; 500; 702) located adjacent the first compartment (701B); and a trajectory arc fault, comprising: a cover (204; 405; 704B) relief intermediate pressure located within the housing (200; 700) between the first compartment (201; 701B) and the second compartment ( 202; 702), and a lid (205; 504; 705) pressure relief top located on an outer surface of the second compartment (500; 702); Relief intermediate pressure and the cover (504; 705) of relief pressure higher configured to close in the absence of a fault (207, 707) arc in the housing (200; 700 cap (;; 405 704B 204) being ), and being the cover (204) relief intermediate pressure and the cover (504) of relief pressure higher configured to open based on the presence of the fault (207; 707) arc in the housing (200; 700), so that the plasma of the fault (207; 707) arc is discharged from the first compartment (201) to the interior of the second compartment (202; 500) through the cover (204) relief open intermediate pressure and outside the second compartment (202; 702) through the cover (504; 705) relief open top pressure, wherein the cover (504) relief higher pressure further comprises a connection (506) configured to attach the lid (205) relief over the outer surface (503) of the second compartment (202 pressure; 50 0), and a safe (507) which engages the outer surface (503) of the second compartment (202; 500) in the absence of failure (207) arc.
