The invention aims at providing a cleaning platform which can solve the problems in the prior art and effectively and automatically clean a disconnecting line of a transformer substation. In order to achieve the aim, the cleaning platform for cleaning the disconnecting link of the transformer substation comprises a cuboid fixed part. A horizontal extension rod extending outwards is arranged on the cuboid fixed part. One end of the extension rod is connected with the fixed part. The other end of the extension rod is provided with a vertical rotating motor. A rotating shaft of the rotating motor is connected with a cleaning head. The cleaning head comprises a cylindrical body and a plurality of flexible cleaning strips arranged on the side wall of the cylinder body. The cleaning platform can have the following technical advantages that due to the structure, the cleaning head can easily enter a contact of the disconnecting link of the transformer substation; the contact of the disconnecting link of the transformer substation is cleaned after the cleaning head is controlled by a motor to rotate, and the cleaning platform is convenient to operate and good in cleaning effect.
