Abstract: In order to improve the level of power safety production and eliminate the threat of residual charges in high-voltage capacitive equipment to operators, this article analyzes the discharge model of capacitive equipment and proposes a discharge rod design with grounding self inspection and visualization of discharge process. The discharge rod adopts a core piercing design for easy disassembly; Equipped with grounding path self check function, ensuring the continuity of the discharge circuit; The discharge indication function has been achieved using data fitting algorithms, greatly improving the level of safety production.
