Quantitative air inlet method of transformer oil and sample compounding device thereof

Abstract

The invention provides a quantitative air inlet method of a transformer oil and a sample compounding device thereof, and belongs to the field of sample compounding devices of the transformer oil. The sample compounding device comprises an electronic weighing vehicle, wherein an oil tank is arranged on the electronic weighing vehicle, the oil tank is provided with a pressure meter, a temperature sensor and a heating unit, a through hole A and a through hole B are respectively formed in the top of the oil tank and the bottom of the oil tank, and the through hole A and the through hole B are respectively connected to an air outlet device and an oil feeding device through pipelines; two circulation holes are formed in the oil tank, and the two circulation holes are connected to a circulation device through the pipelines; a capsule is arranged in the oil tank, and the capsule is connected to a capsule controlling device through the pipelines; an air hole is formed in the top of the oil tank, the air hole is connected to a vacuum device, and a detection opening is formed in the bottom of the oil tank. According to the sample compounding device, the sample of the transformer oil can be accurately compounded, and an online monitoring device can be tested.

Description

technical field [0001] The invention provides a transformer oil quantitative intake method and a sample preparation device thereof, belonging to the field of transformer oil sample preparation devices. Background technique [0002] The transformer is one of the most important core equipment in the power system. Its operating status will directly affect the reliability of the power supply. To evaluate the operating status of the transformer by detecting the dissolved gas content in the transformer oil is to detect latent faults and potential safety hazards of the transformer early and avoid damage to the power grid. An effective means of security incidents. With the continuous advancement of the construction of smart substations, more and more online monitoring devices for dissolved gases in transformer oil have been widely used in condition maintenance work. Although there are many types of online monitoring devices for dissolved gases in transformer oil in the domestic mark...

AI Technical Summary

Problems solved by technology

Due to the many influencing factors in the traditional preparation process, the accuracy of the oil sample preparation is poor, and the amount and concentration range of the oil sample prepared at one time are also very limited, which affects the comprehensive and accurate inspection work of the detection device.
