AI Technical Summary
Existing Rogowski coils rely on glue or epoxy resin to connect the main coil to the connector, resulting in weak connections that are prone to loosening or falling off, affecting the stability of the power distribution system.
It adopts a ring-shaped tightening multi-branch assembly and a screw pressure plate assembly, and fixes the Rogowski coil body through a detachable axial connection by tightening and pressing, replacing the traditional glue or epoxy resin fixation.
It improves the connection strength of Rogowski coil connectors, reduces the risk of failure, and enhances the stability of the power distribution system.
