Automatic calibration device for dynamic error of movable on-line oil gas monitoring system

Abstract

The invention relates to the technical field of power supply and transformation, and particularly relates to an automatic calibration device for dynamic error of a movable on-line oil gas monitoring system, which is used for chromatographic analysis of transformer oil. A high-strength carbon steel rack is an L-type rack, and vibration damping pneumatic tires are arranged on two sides of the rear end of a horizontal frame of the high-strength carbon steel rack; the horizontal frame of the high-strength carbon steel rack is provided with a power supply control box and a pipeline cleaning circulating pump, and two sides of the front end of the high-strength carbon steel rack are provided with telescopic universal bearing frames; an on-line monitoring system for gas in Calisto 9 type high-precision oil is fixedly arranged in the front side of a vertical rack of the high-strength carbon steel rack through a disk type wideband shock absorber at the upper end and a loading low-frequency composite shock absorber at the lower end. The automatic calibration device for the dynamic error of the on-line movable oil gas monitoring system, disclosed by the invention, is simple in structure and convenient to use, and can effectively realize the on-line intelligent monitoring and fault diagnosis of an oil chromatography in a fixed-point and timing manner movably and regularly.

Description

technical field [0001] The invention relates to the technical field of power supply and transformation, in particular to an error dynamic automatic calibration device of a movable oil-gas online monitoring system used for transformer oil chromatographic analysis. Background technique [0002] Oil chromatographic analysis is an effective measure for on-line monitoring of transformer operation. Because it does not need to power off the equipment during monitoring, it can improve the accuracy of equipment failure analysis by cooperating with other tests, and it is not affected by external factors. Therefore, the chromatographic analysis of transformer oil has really become an effective way to discover hidden dangers in important electrical equipment such as transformers and prevent accidents. [0003] At present, domestic research on online monitoring of gas in oil has done a lot of basic research work. The current situation is that a number of chromatographic manufacturers hav...

Problems solved by technology

[0003] At present, domestic research on online monitoring of gas in oil has done a lot of basic research work. The current situation is that a number of chromatographic manufacturers have emerged one after another, and a variety of monitoring methods have been produced. One transformer is matched with one oil chromatographic online monitoring device. Moreover, it is fixed during on-site installation and cannot be inspected externally, resulting in the problem of low test stability and accuracy, and the measured value will not be able to accurately evaluate the status of the equipment
