Compared with the prior art, the method has the advantage that the whole process of source, flow and confluence of the sulfur hexafluoride gas is subjected to material management and control.

Description

technical field [0001] The invention relates to the field of gas material control, in particular to a method and system for controlling sulfur hexafluoride material based on big data. Background technique [0002] Sulfur hexafluoride is an excellent insulating and arc-extinguishing medium, and has been widely used in the power industry. With the increase in the number of sulfur hexafluoride electrical equipment year by year, the amount of sulfur hexafluoride gas continues to increase. The impact of sulfur gas emissions on the atmospheric environment has received extensive attention from all walks of life in recent years. [0003] At present, its digital control is still in its infancy. At present, the research focuses on the recovery, purification and reuse of sulfur hexafluoride gas. There is no systematic research on the management and control of sulfur hexafluoride recovery and reuse based on big data technology. [0004] The existing SF6 gas control and recycling work...

AI Technical Summary

Problems solved by technology

However, limited by complex on-site working conditions, it is impossible to weigh the gas in some cases, and it is impossible to obtain accurate gas consumption information

[0007] 2) There is no associated ledger established between sulfur hexafluoride gas and electrical equipment

[0008] At present, there is no technical reference to the integrated management and control of sulfur hexafluoride gas equipment and sulfur hexafluoride gas information. It is difficult to trace the source of inflation gas in the equipment and the information of gas supply / recovery, which affects the accurate evaluation of equipment status and work effectiveness

Sulfur hexafluoride accounts are complicated and the degree of intelligence is not high

In the process of using sulfur hexafluoride gas, multi-professional and cross-departmental participation, many ledgers, complicated control information, and inconvenient cross-professional query, lack of intelligent, integrated, and widely applicable integrated control platform

[0009] In view of the problems of unclear control mode, outdated data collection method and imperfect operation and maintenance system of the current "sulfur hexafluoride recycling process", it is urgent to develop a sulfur hexafluoride material control technology to realize the dataization of sulfur hexafluoride gas Control, reveal key emissions and inefficient recovery links, grasp the gas loss in each link and grasp the health of equipment through modeling and analysis of big data, predict the amount of new gas purchases, gas recovery, purified gas demand and reuse
