The invention relates to an inspection tour walkway of a valve hall of a converter station. The inspection tour walkway is characterized in that the inspection tour walkway is of a metal frame structure, an upper transverse beam, a lower transverse beam, a plurality of end beams and a metal wall are welded with one another to form the metal frame structure, the upper transverse beam, the lower transverse beam and the metal wall are parallel to one another and respectively form the top and the bottom of the metal frame structure, the various end beams are sequentially connected with one another to form two [-shaped structures, and the two [-shaped structures and the metal wall are respectively fixedly connected with one another to form two ends of the metal frame structure; a metal wire mesh is fixedly arranged on the outer side surface of the metal frame structure, metal shielding layers are fixedly arranged at the top, the bottom and the rear end of the metal frame structure, and a metal door is arranged at a communication position of the front end of the metal frame structure and a control building of the valve hall; the integral metal frame structure, the metal wire mesh, the metal shielding layers and the metal door are connected with one another to form a Faraday cage. The inspection tour walkway has the advantages that high-voltage electric equipment can be effectively prevented from discharging electrostatics to staffs in the inspection tour walkway, electromagnetic interference can be shielded, and personal safety accidents can be prevented.
