Abstract
Apparatus for protecting a plurality of electrical components. In a preferred embodiment, the apparatus comprises a shell formed from an electrically conductive material. An access door is provided in the shell for selectively gaining access to the electrical components. The shell is equipped with grounding apparatus for conducting electrical current created when a lightning strike communicates therewith to a ground. The shell is also equipped with a magnetic shield for substantially shielding the plurality of electrical components from electromagnetic fields created in the shell as a result of electrical current passing therethrough.

Apparatus for protecting a plurality of electrical components, comprising:
- a shell member fabricated from a first electrically conductive material, having an interior surface and defining an interior space for enclosing said plurality of electrical components therein;
- grounding means attached to said shell member for conducting electrical current created when a lightning strike communicates with said shell member to a ground;
- and
- a non-laminated magnetic shield means, comprising a second material, attached to said interior surface of said first material in a spaced relationship to create a space therebetween for receiving a thermal insulating material therein, and adapted to substantially attenuate an electromagnetic field created inside the shell of said first material when said lightning strike communicates with said shell member and to substantially shield said plurality of electrical components from electromagnetic fields created in said first material when said lightning strike communicates with said shell member.
A building for protecting a plurality of electrical components, comprising:
- a plurality of building members fabricated from a first electrically conductive material, said building members being welded together to form a shell for housing said electrical components therein;
- a door member in said shell, said door member fabricated from said first material and being selectively openable and closeable such that when said door member is closed, said door member cooperates with said shell to substantially completely enclose said plurality of electrical components therein;
- grounding means attached to said shell for conducting electrical current created by a lightning strike to a ground;
- and
- a non-laminated magnetic shield means attached to said shell and said door member for substantially shielding said plurality of electrical components from electromagnetic fields created in said shell when said lightning strike communicates therewith
- vent means in said shell member and said magnetic shield means for selectively providing ventilation to said interior of said building, comprising guard means fabricated from a material adapted to substantially attenuate said electromagnetic fields.
