Abstract

The invention discloses a transformer oil detection device and oil-filled electrical equipment. The transformer oil detection device specifically comprises a probe, a signal processing circuit and background equipment, wherein the probe is arranged in transformer oil filled with electrical equipment, the probe comprises a hydrogen-sensitive sensor, and the hydrogen-sensitive sensor is used for detecting the content of hydrogen in the transformer oil and outputting a detection signal; the signal processing circuit is in signal connection with the probe and is used for processing the detection signal to obtain a hydrogen content value in the transformer; and the background equipment is in signal connection with the output end of the signal processing circuit and is used for outputting alarminformation for prompting when the hydrogen content value exceeds the standard. The detection device in the scheme can output the detection result and the alarm information in real time, the detectionefficiency is improved, and the influence on the safe operation of the oil-filled electrical equipment is avoided.

Description

technical field [0001] The present application relates to the field of electric power technology, and more specifically, relates to a hydrogen detection device for transformer oil and oil-filled electrical equipment. Background technique [0002] General oil-filled electrical equipment is filled with transformer oil, which is used to cool down the windings or components, suppress arcs and improve insulation. Transformer oil is a kind of mineral oil obtained through distillation and refining from natural petroleum. It is a pure and stable liquid natural hydrocarbon with low viscosity, good insulation and good cooling performance obtained by refining the lubricating oil fraction in petroleum with acid and alkali. Compound mixture. Commonly known as square shed oil, light yellow transparent liquid. [0003] When there is a fault in the oil-filled electrical equipment, a large amount of dissolved gas such as hydrogen will be produced in the transformer oil, so this kind of dis...
