It is defined in individual accompanying drawing, then in subsequent accompanying drawing which further need not be defined and is explained.
Therefore, the detailed description of embodiments of the invention below to providing in the accompanying drawings is not intended to limit claimed
The scope of the present invention, but be merely representative of the present invention selected embodiment.Based on the embodiment in the present invention, this area is common
The every other embodiment obtained under the premise of creative work is not made by technical staff, belongs to the model of present invention protection
Enclose.
As shown in figure 1, being a kind of frame structure schematic diagram of intelligent maintenance system provided in an embodiment of the present invention 100.Should
Intelligent maintenance system 100 include server 101, at least one data transmission device 103 and with each data transmission device 103
The testing equipment group 105 for obtaining the operating state data of transformer for connecting one to one.Wherein, the data transfer dress
Put 103 to communicate to connect with the server 101 by wired or wireless network, to realize the transmission or interaction of data.The inspection
Measurement equipment is electrically connected with the data transmission device 103, and the operating state data of the transformer for obtaining is passed through data
Transmitting device 103 uploads onto the server 101.According to the data for receiving, the server 101 judges whether transformer occurs event
Barrier, if breaking down, generates and shows failure prompting message to remind administrative staff.
The testing equipment group 105 includes short interruption detector 1051, temperature sensor 1053 and chromatograph
1055.The specific work process of the intelligent maintenance system 100 is, when the short interruption detector 1051 is preset at interval of first
Between obtain a transformer winding current, the temperature sensor 1053 at interval of the second Preset Time obtain a transformer
Operating temperature, and the chromatograph 1055 is under manual control at interval of the 3rd Preset Time in current transformer
Transformer oil carry out a chromatography and obtain analyze data, wherein, the winding current, operating temperature and chromatography
The analyze data for obtaining afterwards constitutes the operating state data of the transformer.First Preset Time and the second Preset Time can
With identical, it is also possible to different.3rd Preset Time is typically larger than the first Preset Time and the second Preset Time, is such as 1 day
Or 2 days etc..
Then, data transmission device 103 sends the operating state data that testing equipment is uploaded to server 101.
According to the winding current in the operating state data for receiving, the server 101 judges whether transformer is short-circuited (such as circle
Between short circuit, the too high short circuit for causing of transformer core temperature or shunting switch mechanical breakdown cause short circuit etc.) or breaking (coil
Fusing causes open circuit etc.), and judge according to operating temperature whether the environment temperature in transformer is abnormal.When judge occur it is short
Road, open circuit and environment temperature exception three in it is at least one when, the server 101 is transferred in the operating state data
Chromatogram analysis data failure judgement type and position of failure point.Finally, server 101 is according to the unique of data transmission device 103
Identification information is searched the inquiry list and obtains the positional information of transformer for breaking down, generate comprising the positional information,
After the failure prompting message of fault type and position of failure point, the failure prompting message is shown with remind administrative staff and
When arrange attendant carry out troubleshooting.
It is appreciated that the intelligent maintenance system 100 can also be analyzed according to operating state data in advance it is possible that
Failure, to remind administrative staff to strengthen taking precautions against, safeguard in time, improve the maintenance effects and service life of transformer.

Shown in unlike, the intelligent maintenance system 100 also include with the server 101 communication connection first terminal 107.
107 corresponding user of the first terminal is attendant.101 internal memory of the server contains one includes the first terminal 107
And the data list of the transformer corresponding with the first terminal 107, that is, represent the user of the first terminal 107 be responsible for this
The maintenance work of one or more corresponding transformers of one terminal 107.
The server 101 after the failure prompting message is generated is inquired about the data list and is obtained and generation event
After the corresponding first terminal 107 of the transformer of barrier, the failure prompting message is sent into the first terminal 107, to point out dimension
Shield personnel are processed to failure.
After attendant carries out troubleshooting, the data is activation related to maintenance can also be carried out to server 101
Storage makes the server 101 be trained study based on neural network model and the historical data to constitute historical data.Its
In, it is described to safeguard that data include time of attendant's start to process failure, actual position of failure point, actual failure classes
Type, the time for whether having eliminated failure and end process.
It is described study is trained based on neural network model and the historical data to refer to, server 101 according to multiple therefore
Barrier safeguards that data carry out statistical analysis, learns each physical fault type and the operating state data corresponding to actual fault point,
Fault judgment method is updated, the accuracy rate of breakdown judge is lifted.
Furthermore, in the present embodiment, attendant can also carry out regular visit to its be responsible for transformer.It is capable of achieving
Ground, transformer are provided with Quick Response Code, and attendant scans the Quick Response Code into corresponding interface, take pictures and after information is patrolled and examined in typing
Upload onto the server and 101 recorded.
