Problems solved by technology
[0002] At present, the pressure of SF6 gas in substations is released, and the hidden dangers of gas leakage are increasing year by year. Especially when the fully enclosed GIS equipment is gradually put into operation, the monitoring of SF6 gas pressure is becoming more and more important, even related to the safe and stable operation of substation equipment. However, the current substation The SF6 pressure monitoring of the equipment must be surveyed at the equipment site. Remote monitoring has not been realized, let alone the online analysis function. A complete SF6 information database system has not been established, nor can it be uploaded to the centralized control center through the network, and the substation equipment has not been realized. SF6 pressure information automatic comprehensive management

Embodiment Construction
[0025] The present invention is a substation SF6 gas pressure monitoring and statistical analysis system, which is composed of each air chamber pressure sensor 7 of the SF6 gas pressure terminal layer 8 and the data acquisition board 5 on the SF6 gas pressure acquisition layer 6 through AD or 485 serial bus. connected, the data acquisition board 5 is connected with the industrial computer 1 of the SF6 gas pressure monitoring layer 2 through the wireless receiving and transmitting device.
[0026] Such as figure 1 As shown, gas pressure data with an accuracy of 0.01MPa is collected from each gas chamber pressure sensor 7 of the SF6 gas pressure terminal layer 8, and transmitted to the data acquisition board 5 through AD or 485 serial bus, and then through a wireless transmission device, that is, wireless data transmission The receiving end 3 and the wireless data transmission sending end 4 send the pressure data to the industrial computer 1 of the SF6 gas pressure monitoring la...

The invention relates to the technical field of a system and a method for monitoring and statistically analyzing SF6 gas pressure of a transformer substation, which can performing real-time acquisition and qualitative and quantitative analysis on SF6 pressure information of transformer substation equipment and transmitting the information to a comprehensive information management platform of a production management system (PMS) through a network in real time. According to the system, all gas chamber pressure sensors on an SF6 gas pressure terminal layer 8 are connected with a data acquisition board on an SF6 gas pressure acquisition layer through an AD or 485 serial bus; and the data acquisition board is connected with an industrial personal computer on an SF6 gas pressure monitoring layer through a wireless transceiving device. The system and the method are easy and convenient to operate, practicable and convenient to run and schedule; and the operation condition of SF6 gas of the transformer substation can be accurately mastered by monitoring staff in a remote distance, so that first reliable equipment SF6 gas pressure operation information is provided for condition-based maintenance, SF6 equipment can be conveniently maintained by relevant professional staff, and a transplantable valuable experience is provided for maintenance of a geographic information system (GIS) transformer substation. By the system and the method, a blank of the technical field is filled; and the system and the method have considerable social and economic benefits.
