[0002] The offshore wind turbine high-voltage cable terminal temperature inspection system is a real-time temperature monitoring and early warning system designed for high-voltage cable connection points (such as terminal connectors) in offshore wind farms. Its core function is to collect cable terminal temperature data in real time through temperature sensors and, combined with intelligent analysis algorithms, achieve early warning of equipment health status and remote operation and maintenance management.
