Electrical cabinet wall for an electrical cabinet of a wind turbine

An electrical assembly for a wind turbine, comprising:

• an electrical cabinet comprising a plurality of cabinet walls defining an internal volume, the electrical cabinet comprising at least one opening;
• and,
• one or more electrical components configured within the internal volume,
• wherein at least one of the cabinet walls are configured to cover at least a portion of the opening of the electrical cabinet, at least one of the cabinet walls comprising an inner panel and an outer panel mounted to the inner panel, the inner panel comprising an inner vent, the outer panel comprising an outer vent and an outer wall with a plurality of side walls extending therefrom so as to define an inner cavity, the plurality of side walls comprising a top side wall, a sloped bottom side wall, and opposing side walls, the inner and outer panels arranged together so as to define a flow path between the inner and outer vents,
• wherein, during normal operation, air is directed from outside of the electrical cabinet to the internal volume of the electrical cabinet via the flow path so as to cool the one or more electrical components, and
• wherein, during a fault event, gas is permitted to exit the internal volume of the electrical cabinet via the flow path.

A method for mitigating arc energy in an electrical assembly of a wind turbine, the electrical assembly having an electrical cabinet defining an internal volume with one or more electrical components contained therein, the method comprising:

• covering an opening of the electrical cabinet with a cabinet wall, the cabinet wall having an inner panel with an inner vent and outer panel with an outer vent, the inner and outer panels arranged together so as to define a flow path between the inner and outer vents, the outer panel having an outer wall with a plurality of side walls extending therefrom so as to define an inner cavity, the plurality of side walls comprising a top side wall, a sloped bottom side wall, and opposing side walls;
• during a fault event, permitting gas to exit the internal volume of the electrical cabinet via the flow path;
• and
• during normal operation, directing cooling air from outside of the electrical cabinet to the internal volume of the electrical cabinet via the flow path so as to cool the one or more electrical components.
