ARC-RESISTANT PRESSURE DAMPER PANEL

摘要

An electrical assembly includes an arc exhaust system within at least one section defined by a plurality of panels, including a roof panel. The section houses an electrical distribution device and includes an arc exhaust path that originates at the device and ends at the arc exhaust outlet. In the exhaust path, a damper panel is mounted inside the enclosure roof panel such that an air pocket separates the two panels. When an arc event occurs, a pressure wave travels from the electrical distribution device in a first direction towards the damper panel, which receives the impact of the pressure wave and redirects it in a second direction towards the exhaust outlet and outside the electrical assembly.
