Abstract

The embodiment of the invention provides a stirring viscosity measuring device. The measuring device comprises an oil path unit, a headspace degassing unit, a gas path unit, a measuring unit and a control unit, wherein the oil path unit is used for obtaining a cooling oil sample from oil-immersed equipment; the headspace degassing unit comprises a measurement sensing assembly used for obtaining the viscosity of the cooling oil sample, and the stirring speed of a stirring component is determined according to the viscosity, which is measured by the measurement sensing assembly, of the cooling oil sample so as to enable the headspace degassing unit to conduct degassing on the cooling oil sample to obtain a gas sample to be measured; the gas path unit is used for enabling the to-be-measured gas sample in the headspace degassing unit to enter the measuring unit; the measuring unit is used for measuring the concentration of the characteristic gas in the to-be-measured gas sample by utilizinga photoacoustic spectrometry device; and the control unit is used for determining the operation fault of the oil-immersed equipment according to the concentration of the characteristic gas, so that the measuring device can acquire the sampling data in real time, and can predict the operation fault of the oil-immersed equipment according to the concentration of the characteristic gas so as to givean alarm, thereby avoiding the damage of the oil-immersed equipment.

Description

technical field [0001] The present application relates to the field of transformer oil and gas monitoring, in particular to a stirring viscosity measuring device. Background technique [0002] With the rapid development of the national economy, the demand for electricity in all walks of life continues to rise. Today, the power system is also developing towards ultra-high voltage, large capacity and automation. Therefore, a large number of large oil-immersed power equipment ( Such as transformers), in order to ensure the safe operation of the power system, preventive inspection and monitoring of the operating status of large oil-immersed power equipment such as transformers must be carried out. [0003] Since oil-immersed power equipment adopts insulation structures such as insulating oil, oil paper or oil paper board, when thermal faults, discharge faults or insulating oil and paper aging occur inside the equipment, various gases will be generated, and these gases will disso...
