Method and system for detecting partial discharge of transformer

The invention provides a detection method and system for partial discharge of a transformer, and relates to the technical field of discharge detection, and the method comprises the steps: taking a partial discharge point position set of the transformer as a predetermined detection point position; dynamically detecting the transformer to obtain an initial signal sequence; performing multi-dimensional information collection based on the predetermined environment features to obtain real-time environment information; adjusting the initial signal sequence based on the real-time environment information to obtain a target signal sequence; generating a visual signal graph according to the first signal time sequence of the first point location; and analyzing the visual signal diagram to obtain a target discharge point location. The invention solves the problems that the existing partial discharge detection technology generally cannot realize real-time detection of the operation state of the equipment, so that the part
