Fault diagnosis method and device for high-voltage circuit breaker operating mechanism and electronic equipment

The invention discloses a fault diagnosis method and device for a high-voltage circuit breaker operating mechanism and electronic equipment. The method comprises the following steps: acquiring a current signal of an opening and closing coil on a high-voltage circuit breaker, and extracting current feature data from the current signal of the opening and closing coil; establishing a first sample setbased on the current signal of the opening and closing coil, and establishing a first feature set based on the current feature data; establishing a fault sample set based on the first sample set andthe first feature set; calculating the importance degree of each piece of feature data in the first feature set, and counting the feature data of which the importance degree is smaller than a preset importance degree threshold to obtain a target feature subset; constructing a fault diagnosis model of a high-voltage circuit breaker operating mechanism based on the target feature subset, the first feature set being divided i
