The invention provides a local stripping and cutting device for a high-voltage cable. The local stripping and cutting device for the high-voltage cable comprises a cable main body, a fixing device, adriving motor and a cutting device; the fixing device fixes the cable main body; the cutting device is detachably installed at the top of the fixing device; and the driving motor is connected with thecutting device. The invention further provides a local stripping and cutting method for a high-voltage cable. According to the local stripping and cutting device and method for the high-voltage cableof the invention, the fixing piece and the cutting device can be matched with each other, so that the positioning of the cutting device on the fixing device can be changed; annual cutting and longitudinal cutting can be conducted on the cable on the fixing piece; layered stripping and cutting can be conducted on the cable; it is guaranteed that the notch of the cable is smooth in a stripping andcutting process; and conductors in the cable are not damaged.
