The invention relates to a disconnecting switch opening and closing abnormal state monitoring method, which comprises the following steps: arranging an attitude sensor on a disconnecting switch moving end, resolving the attitude of the disconnecting switch moving end through the attitude sensor, and judging whether a disconnecting switch acts or not; when the disconnecting link acts, motion parameters of the disconnecting link are obtained through calculation of an attitude sensor, the motion parameters of the disconnecting link are substituted into the motion model to obtain a motion characteristic value through calculation, the obtained motion characteristic value is compared with a database standard model, and whether the disconnecting link of the disconnecting switch has an abnormal mechanical state or not is judged; the database model is obtained by the following steps: collecting abnormal motion parameters when the disconnecting switch in an abnormal mechanical state acts, substituting the abnormal moti
