Abstract

The invention relates to a standard oil preparation device and a method. The standard oil preparation device comprises four cylinders, etc. A first cylinder is connected with a second cylinder which is connected with a third cylinder. A fourth cylinder is connected among the body of the connecting valve of the second cylinder and the third cylinder and the cylinders. An oil inlet and a gas inlet are arranged on the fourth cylinder. An oil discharging port is arranged on the first cylinder. Gas inlets are respectively arranged on the second, the third and the fourth cylinders. The first, the second and the third cylinders are wholly arranged in the nitrogen insulation environment. The first cylinder and the third cylinder are driven by blank oil as medium. The standard oil preparation device has the advantages of good air tightness, uniform and stable standard oil and using convenience. Prepared standard oil with different concentrations can be used for the comprehensive evaluation on the online chromatographic property, including the accuracy of data, the minimum detection concentration, the transmission of the data, the calibration mode of the device, etc. The field calibration can be implemented on the running online chromatography and the defect elimination can be implemented on the running online chromatography according to the data.

Description

Technical field: [0001] The invention relates to a device for preparing standard oil whose real content of dissolved gas components can be known. It belongs to the technical field of power system machinery. Background technique [0002] At present, many large transformers are equipped with online chromatographic detection systems. However, the principle of each online chromatographic detection system is different. Some use fuel cell technology to detect characteristic gases online, and some use conventional column separation technology to detect characteristic gases online. So far, various online chromatographic detection data rarely match the laboratory chromatographic data, resulting in confusion when judging faults, and accidental outages are not uncommon. Although domestic online chromatographic devices have been widely used, there is no set of methods and system equipment for comprehensive evaluation of online chromatographic performance, including data accuracy, mini...
