Problems solved by technology
[0003] Before diagnosis, it is necessary to obtain the insulating oil in the transformer as an oil sample. In order to ensure the correctness of the fault diagnosis result, some oil will be drained before sampling. The current oil extraction and discharge process is basically manual. , the efficiency is low, and the amount of oil draining and oil extraction is not well controlled, resulting in inaccurate diagnosis results

The invention provides an advanced diagnostic device for oil chromatography, which includes an oil extraction valve, an oil pipeline, an oil collection tank, an oil circuit switching mechanism and a gas chromatograph. The oil pipeline includes a vertical pipeline and a horizontal pipeline, and a metal oil baffle is arranged in the horizontal pipeline , the oil pipeline communicates with the first cavity and the second cavity in the oil collection tank through the horizontal pipeline, and under the action of the oil circuit switching mechanism, the metal oil baffle can be rotated to the side of the first cavity or the second cavity On one side, the first cavity is used to store part of the insulating oil in advance. When a certain amount of insulating oil is stored in the first cavity, the oil circuit switching mechanism can switch the delivery of the insulating oil to the second cavity, thus ensuring that it enters the first cavity. The insulating oil in the second cavity is representative, preventing the gas contained in the insulating oil delivered in the early stage from being incomplete and corresponding to the accuracy of the final fault diagnosis result.
Description
Technical field [0001] The present invention relates to the technical field of detection of the transformer, in particular, it relates to an oil chromatographic advanced diagnostic apparatus. Background technique [0002] Large power transformer, the current is almost insulating and cooling with oil, transformer oil and insulating oil, solid organic materials (paper and cardboard) due to various factors electricity, heat, oxidation and the like will be in the local arcs operating voltage gradual deterioration, cracking into low molecular weight hydrocarbon gas and carbon monoxide gas and carbon dioxide, and most of the dissolved in oil, the oil in the transformer by gas chromatographic analysis to analyze the gases dissolved in transformer oil, and the transformer in order to diagnose internal faults are present in the common methods of monitoring the status of the transformer. [0003] Before making a diagnosis need to get a transformer insulating oil as the oil sample, in order...
