METHODS AND APPARATUS FOR MITIGATING ARC FLASH INCIDENT ENERGY IN MOTOR CONTROL DEVICES
摘要
Industrial motor control apparatus and techniques are presented for mitigating incident energy associated with an internal arcing. Interior enclosure surfaces and/or surfaces of electrical components are provided with textures and/or coatings which may be non-reflective with respect to visible and/or infrared light in order to redirect or absorb incident energy associated with internal arcing conditions. The electrical components are also arranged so as to substantially minimize the percentage of back wall exposure, and filler material and/or tile structures may be mounted within the enclosure, which may be non-reflective and/or have textured surfaces or coating layers to mitigate incident arcing energy. In addition, baffles or barriers may be provided within the enclosure to redirect or absorb incident energy from internal arcing.
