The invention discloses a sugar-based insulation paper aging detection method, device and equipment and a storage medium, and the method comprises the steps: detecting the sugar concentration of insulation oil in an oil-immersed transformer, the insulation paper being soaked in the insulation oil; calculating the total content of furfural and sugar in the insulating oil according to the concentration of sugar; detecting the concentration of furfural in the insulating oil in the oil-immersed transformer; removing the interference of furfural in the total content according to the concentration of furfural in the insulating oil to obtain the independent content of sugar; generating the aging degree of the insulation paper according to the independent content of the sugar. According to the embodiment, the aging degree of the insulation paper is evaluated according to the content of sugar in the insulation oil, shutdown of an oil-immersed transformer is not depended on, local power failure of a power grid is not c
