Description

Technical Field

[0001] This utility model relates to the field of main unit power supply compartment technology, specifically to an anti-arc isolation component for a computer main unit power supply compartment. Background Technology

[0002] As intelligent computing mainframes develop towards higher power density, the electrical load within the power supply compartment increases dramatically, significantly raising the risk of arcing faults. Traditional insulation panels often use a single metal structure or basic insulation material, which has the following drawbacks:

[0003] Passive protection: Relying solely on physical isolation to block the electric arc, it cannot actively discharge the charge and is prone to secondary arcs due to charge accumulation;

[0004] Heat dissipation conflict: Metal partitions obstruct airflow, while adding heat dissipation holes reduces insulation strength, resulting in a vicious cycle of temperature rise and arc risk. Utility Model Content
