Recently, the China Electrotechnical Society issued the group standard "Integrated Intelligent Grounding Box Technical Specification for Integrated Live Monitoring Function of High Voltage Cable". The standard of this group stipulates the basic composition, working conditions, technical requirements, inspection rules, signs, transportation and storage of the integrated high-voltage cable live monitoring function, and is suitable for the design, production, use and inspection of the comprehensive intelligent grounding box for high-voltage cable lines of 110kV and above.
The comprehensive intelligent grounding box is an online monitoring equipment that should have grounding functions and integrate various types of online monitoring modules to realize the processing, analysis and signal acquisition unit control of the state quantity of cables and cable channels, and can communicate with the monitoring and analysis system in a standardized manner.
Monitoring and analysis system refers to a computer master system that can access high-voltage cables and cable channels online monitoring information, and centralize storage, processing, analysis, display and application.
