Transformer oil fluorescence signal multivariate correction acquisition and analysis device and method

The invention discloses a transformer oil fluorescence signal multivariate correction acquisition and analysis device and method, belongs to the technical field of transformer fault diagnosis, and solves the problems of large size, large weight, high cost and inconvenience in use when a fluorescence spectrum signal generated by transformer oil is acquired and analyzed by an existing fluorescence spectrophotometer. The positive multivariate correction optical filter or the negative multivariate correction optical filter is rotated in place, so that the center lines of the optical fiber head, the positive multivariate correction optical filter or the negative multivariate correction optical filter and the receiving lens of the fluorescence detector are on the same straight line; fluorescence emitted by the transformer oil sequentially passes through the optical fiber interface, the optical fiber head, the positive multivariate correction optical filter or the negative multivariate correction optical filter and
