Compared with the QFS2 type 350MW two-water internal cooling product stator bar, in order to meet the special requirements of superior transient performance, the camera coil width is increased and the body length is longer. The change of structure brings about the corresponding change of the processing technology. Although the coil is still replaced by the mature linear 540° weaving method, the production process has been changed from integral gelatinization to straight-line gelatinization, forming die end and straight line. A new way of secondary gelation. In order to allow the operator to complete the operation without errors, the process and manufacturing personnel have strengthened the technical disclosure before the trial production. The craftsman introduces the operator to the difference between the old and new products, the processing of the new process and the precautions. Through the technical disclosure, the operator has prepared the replacement of the S-bend mold and the calibration of the pitch template in advance. A new type of release material was used in the trial production process, which saved a lot of twill tape and yarn band auxiliary material; the use of the straight tape wrapping machine also significantly improved the manufacturing speed. Factory manufacturing, process, quality inspection and other professionals work together to complete the trial production of all 10 test coils to meet the project-related verification requirements. The development of 300Mvar dual-water internal cooling camera overcomes the difficulty of tight time and heavy tasks. It is a bold innovation and careful verification in the development of each development node; the trial production of this test coil is one of the epitome. The development team is united in the city, based on the position, meticulously build this innovative and important product.
