AI Technical Summary
The fixed installation of existing monitoring devices inside high-voltage switchgear makes it difficult to accurately capture subtle anomalies such as local hot spots in real time due to the influence of spatial distance on monitoring accuracy.
A multi-dimensional adjustable monitoring component was designed, including a guide plate, a threaded rod, and a limit plate. The threaded rod is driven by a motor to move the monitoring component within the switch cabinet. Combined with the adjusting sleeve and mounting plate, flexible monitoring of key areas can be achieved.
It significantly improves the monitoring accuracy of fault indicators such as temperature, gas and sparks, can detect anomalies in a timely manner and issue alarms, covers key monitoring areas, and reduces the impact of spatial distance on monitoring data.
