AI Technical Summary
Existing drawer-type low-voltage switchgear has difficulty ensuring operational safety under abnormal temperature rise conditions, lacks linkage management of multiple drawer units, has insufficient residual voltage signal detection, and has unidirectional uploading communication function, making it difficult to meet the needs of intelligent operation and maintenance and centralized management.
It adopts a multi-parameter monitoring and dual interlocking mechanism, including temperature sensors, position identification devices, mechanical and electromagnetic interlocking components and bus communication interfaces, to achieve comprehensive determination of bus temperature, drawer position and operating parameters, forming a closed-loop control logic, and supporting remote authorization and two-way communication.
It enhances the safety control capabilities of the busbar during operation, ensures the safety and intelligent management of drawer operations, realizes the linkage management of multiple drawer units and residual voltage detection, and meets the intelligent operation and maintenance needs of modern power systems.
