The fracture signal of shear pin occurs in the process of short time load reduction of AGC. During the stop site inspection, it is found that the shear pin was broken, the guide vane limit block fell off, and the movable guide vane was reversed. The analysis shows that the installation and welding mode of the limited block is wrong. Therefore, when the guide vane is subjected to additional load, the position of the fixed guide vane cannot be effectively limited, which leads to the inversion of the fixed guide vane.
