description The invention relates to a transformer iron core clamp disconnection early warning method and device and computer equipment. The method comprises the following steps: acquiring parameters of a transformer iron core clamp in a normal grounding state and a disconnection state to obtain an original parameter-state data set; performing order raising processing on the electrical parameter characteristics in the original parameter-state data set to obtain an order-raised parameter-state data set; calculating a maximum mutual information coefficient in the order-increasing parameter-state data set, wherein the maximum mutual information coefficient and the electrical parameter characteristic represent a normal grounding state and a disconnection state, and obtaining a screening parameter-state data set; calculating a Pearson's correlation coefficient between the electrical parameter characteristics in the screening parameter-state data set to obtain a final parameter-state data set; hyper-parameters of a normal grou
