Abstract
A method is described for the radial locking of the heads of stator windings in large turboalternators coupled to steam turbines, in particular for use in the central region of the heads, whether for generators already in operation, as an improvement in the original mooring of the heads, or in generators of new construction. The two rod layers of the heads are locked onto the between-layer wedges, and thus to each other, so as to form a single hole, thus eliminating the possibility of local vibrations of the rods with respect to the entire head assembly. This is achieved by the use of braces that are threaded at both ends, made of insulating material, preferably glass fibre. The braces are inserted in radial direction between two slot bottom rods and two air gap rods, and are then secured by twin-plate opposing support nuts which respectively rest against two slot bottom rods and two air gap rods. They thus exert a force of traction on the two braces, producing a locking of desired value between the two rod layers. <IMAGE>
