Quality monitoring system of high-voltage transmission and transformation transformer insulating oil

Abstract

The invention discloses a quality monitoring system of the transmission and transformation transformer insulating oil. The system uses easier, and more sensitive and reliable sensors and a sensor system structure; the system can monitor the gas; and more importantly, the system uses the sensors to monitor the comprehensive effect of the physical and chemical parameters of the cracked oil sample under different conditions. The system can be used to transmit the data of the monitoring system to a control center in a wired or wireless mode and can be used for the active preventive maintenance of the smart grid.

Description

technical field [0001] The invention relates to a sensor and a sensor system for monitoring the state of a liquid. The liquids monitored by the invention include transformer insulating oil, engine lubricating oil, transmission lubricating oil, hydraulic transmission oil, and edible oil. In particular, the present invention can also be applied to transmit the data of the monitoring system to the data control center in a wired or wireless manner, and can also be applied to the active and preventive maintenance of the smart grid. Background technique [0002] The arc and sparks caused by the high voltage of the power transmission and transformation transformer crack the molecules of the transformer insulating oil to generate gas, organic acid and water. Water and acid are catalysts for the oil to continue to be oxidized, and the formation of water and acid also leads to an increase in the conductivity of the oil, so that it cannot play the role of insulation. [0003] At pres...

Problems solved by technology

During the on-site collection of oil samples and the long-distance transportation to the laboratory, it is unavoidable that the trace gas dissolved in the oil samples escapes into the air outside the oil samples, or the oil samples cannot be avoided during the on-site collection of oil samples. Gas or impurities in the outside air enter the collected oil sample

In this way, the reliability of the laboratory test data or results will be reduced, and the final test results will have large errors, which will increase the possibility of missed or false positive reports of faults. The degree of influence has a great impact, which has caused great blindness to the maintenance work, increased unnecessary maintenance costs, and thus put expensive and high-value transformers and power transmission and transformation systems in uncertain danger

Also, the above-mentioned monitoring methods cannot be used for on-line monitoring and data transmission of transformer insulating oil quality changes

The above-mentioned problems and problems have always plagued my country's power transmission and transformation industry, and have become the difficulty of monitoring the quality of transformer insulating oil in my country's power transmission and transformation industry, especially the difficulties and technical bottlenecks in the operation of my country's power transmission and transformation grid and the construction of smart grid. Moreover, so far So far, the field still has not come up with a good solution
