Problems solved by technology

The off-line detection of micro-water content in insulating oil in the laboratory is complicated and difficult to control, especially the oil-water separation link is difficult to realize. At the same time, the distance between the transformer and the laboratory is long, the process from oil extraction to detection is complicated and costly, and the real-time performance is poor; online micro-water monitoring It is an effective supplement and perfection of micro-water monitoring in the laboratory
[0003] The patent with the application number CN200820056711 discloses a gas chromatograph used for the determination of moisture in transformer oil sampler, this detection method has high sensitivity and low interference, but the operation is complicated, and it is difficult for ordinary technicians to grasp the equipment. more demanding

Embodiment Construction

[0008] Such as figure 1 Shown is the device connection diagram of the micro-water online monitoring system in transformer oil according to the present invention. The invention provides an on-line measurement system for micro-water content in transformer oil, which includes a humidity sensor, a temperature sensor, a filter unit, a wave detection unit, an amplification unit, a data processing server, and a client monitoring terminal.

[0009] Wherein, the humidity sensor is an alumina humidity sensor or a fringe field capacitive humidity sensor; the temperature sensor is a polyimide capacitive temperature sensor; and the customer monitoring terminal is equipped with micro moisture fault diagnosis software.

[0010] At the measurement site, since the oil temperature of the transformer will have a great influence on the measurement results of the humidity sensor, in order to accurately monitor the micro-water content in the transformer oil in real time, the polyimide film capaciti...

Description

technical field [0001] The invention relates to an auxiliary device of electric power equipment, in particular to an on-line measurement system for micro-water content in transformer oil. Background technique [0002] With the expansion of the structure of the power industry and the continuous improvement of voltage equipment levels, the maintenance of transformers is becoming more and more important, and the measurement of moisture in transformer oil has become a very important part of transformer maintenance. It plays an essential role in the safe operation of the transformer oil. The moisture content has a decisive impact on the insulation of the transformer oil. Excessive moisture content in the oil will accelerate the aging of the insulating material and reduce the insulation, which will lead to the failure of the equipment to operate. Unstable and potentially dangerous, when the moisture content is large, it will cause arcing rings and short circuits in the coil, and e...
