Description
Technical field
The present invention relates to a kind of transformer detection systems, and in particular to a kind of transformer winding internal temperature on-line monitoring system
System.
Background technique
Temperature of oil in transformer is related to the service life of the insulating materials of transformer, when organic insulating material aging in transformer,
Its mechanical strength reduces, the external force of unbearable normal work.It eventually leads to transformer and electric fault occurs, can not work.
Summary of the invention
The technical problems to be solved by the present invention are: current transformer temperature monitoring system is all one change of independent monitoring
Depressor can not accomplish that the same backstage carries out unified monitoring, and the present invention provides a kind of transformer windings to solve the above problems
Internal temperature on-line monitoring system.
The present invention is achieved through the following technical solutions:
A kind of transformer winding internal temperature on-line monitoring system, including several independent subsystems, including several independences
Subsystem, one transformer of a sub- system monitoring；One subsystem includes multiple temperature sensors, the temperature sensor
It is mounted on transformer winding coil surface；Each described temperature sensor is singly connected with an A/D converter, the A/
D converter is connected to same multi-Channel Data Acquisition Card, and the data collecting card connects chip of micro-computer, by microcomputer
It calculates and is analyzed in machine core piece；The output pin of chip of micro-computer is connected with LoRa node module by spi bus；Microcomputer
It calculates machine core piece and the result information of analysis is uploaded to network by LoRa node module；Background system is tied by connecting network
Fruit information.By one transformer of each subsystem monitors, carried out solely by each subsystem with configuration chip of micro-computer
Vertical parsing, is sent to the same backstage by LoRa node module for parsing result, reduces volume of transmitted data, while being also not required to
A large amount of operation is carried out from the background, makes system operation response speed faster, form the same deployment of monitoring system, United Dispatching rule
It draws；An A/D converter is singly connected with by each fibre optical sensor to be converted with traditional by switching switch,
Avoid signal delay.
Further, chip of micro-computer is also connected with GPS positioning module, simultaneously sends out location information when transmitting result
Give backstage.By the corresponding geographical location information of each subsystem, it can be directly viewable the transformer of different location from the background
State facilitates monitoring personnel to monitor.
Further, chip of micro-computer is also connected with memory module, and chip of micro-computer is by received original number
In a storage module according to storage, whenever necessary, backstage sends the request instruction for obtaining initial data on backstage, passes through LoRa node mould
Block receives instruction and is transmitted to wechat computer chip, and chip of micro-computer receives instruction post analysis instruction, requires to adjust according to instruction
Corresponding initial data is taken, then backstage is sent to by LoRa node module.By the way that initial data is carried out to be stored in every height
In system, wireless transfer channel will not be occupied, while also avoiding storing a large amount of initial data from the background, is that running background is slow,
Backstage is obtained when needing, and is easy to understand the historic state information of transformer.
Further, fibre optical sensor is mode Optical Fiber Sensors
The present invention has the advantage that and the utility model has the advantages that
1, the present invention is by one transformer of each subsystem monitors, by each subsystem with configuration microcomputer core
Piece carries out independent parsing, and parsing result is sent to the same backstage by LoRa node module, reduces volume of transmitted data, together
When do not need yet backstage carry out a large amount of operation, make system operation response speed faster, formed monitoring system same deployment, system
One scheduling planning；An A/D converter is singly connected with by each fibre optical sensor to switch with traditional by switching
It is converted, avoids signal delay；
2, the present invention can be directly viewable the change of different location by the corresponding geographical location information of each subsystem from the background
The state of depressor, facilitates monitoring personnel to monitor；
3, the present invention will not occupy wireless transfer channel, together by be stored in each subsystem initial data
When also avoid storing a large amount of initial data from the background, be that running background is slow, obtained when needing from the background, be easy to understand transformation
The historic state information of device.
