Protective apparatus usable with a forced air cooling system and electrical enclosure

摘要

An electrical enclosure apparatus includes a protective apparatus that permits forced-air cooling of the interior of the enclosure while resisting structures that are within in the interior from being blown out of the electrical enclosure as a result of an arc event or other event. The protective apparatus includes a flow apparatus formed from one or more blocks of ceramic material having formed therein a plurality of elongated flow channels. The flow apparatus is supported inside a duct with the use of a support apparatus. The ceramic material from which the flow apparatus is formed is configured to withstand the heat that may be experienced in an arc event and is additionally configured to be sufficiently rigid and tough to retain within the duct any structures within the enclosure from being blown out of the protective apparatus, thereby protecting personnel who may be in the area.

主权项

1. A protective apparatus that is structured for use with a forced air cooling system of an electrical enclosure apparatus, the protective device being structured to resist the discharge of articles therethrough in an arc event within an interior region of the electrical enclosure, the protective apparatus comprising:
a duct having at least a first wall and further having an interior region situated adjacent the at least first wall, the duct being structured to be connected in fluid communication with the forced air cooling system and being structured to carry a stream of air therethrough; a flow apparatus comprising at least a first block formed at least in part of a ceramic material and having a plurality of flow channels formed therein, the at least first block being structured to be situated in the stream of air and to have the stream of air flow through the plurality of flow channels; and a support apparatus comprising at least a first support that is structured to be mounted to the duct, the at least first block structure being situated adjacent the at least first support.
