The utility model discloses an anti-misoperation device used in electric power equipment provided with an operating hole. The anti-misoperation device comprises a shielding block and a fixing seat, wherein a head part of the shielding block shields the operating hole, and the fixing seat is fixed with the electric equipment. A tail part of the shielding block is slidably inserted in a slot in the fixing seat. The fixing seat is provided with a spacing structure which restricts the sliding position of the shielding block in the slot. With the adoption of the anti-misoperation device, in a condition that operation is not allowed, the shielding block shields the operating hole, the spacing structure prevents the shielding block from sliding open and further preventing the operating hole from being exposed, and an unlocking shaft for operating equipment in the operating hole cannot be inserted, so that the normal operation of the electric power equipment is guaranteed; and when an operator is authorized, the spacing structure is opened, the shielding block in the slot slides open for exposing the operating hole, and then the operation is carried out. The anti-misoperation device effectively prevents accidents caused by man-made misoperation. The utility model also discloses the electric power equipment having the anti-misoperation device.
