Design of Intelligent Management System for SF6 Gas Cylinders in Substation Based on 5G Communication Technology
To ensure the timeliness and reliability of intelligent management of sulfur hexafluoride(SF6)gas cylinders in substations,an intelligent management system for SF6 gas cylinders in substations based on 5G communication technology is designed.The state data of SF6 gas cylinders in substations is sensed and collected through devices such as SF6 gas collectors.The data is transmitted to the management module via a 5G transmission module constructed by 5G communication technology,and the network is divided by 5G slicing technology to realize on-demand communication.After receiving the data transmitted via the 5G transmission module,the management module intelligently detects the leakage concentration of SF6 cylinders online based on the non-discriminative infrared differential detection method and checks the SF6 gas online monitoring results to realize the intelligent management of SF6 gas cylinders.The test results show that:the average network transmission rate is between 8～10 Gbit/s,which is very close to the peak transmission rate,and the real-time communication is good;it is able to monitor the operation status of SF6 gas cylinders in real time,the on-line detection accuracy is high,and the average offset degree is lower than 0.035.The system can comprehensively present the leakage situation of the gas,as well as the time of occurrence of the leakage and the concentration of leaking gas.
