Abstract

The present application belongs to the technical field of reactors. Disclosed are a design method for an oil-immersed iron core reactor upper pressing and positioning system, and the system. By means of the design of a constant-pressure structure using a belleville spring and a positioning bowl, a flexible buffer space is formed in the vertical direction, thereby effectively reducing the mechanical vibration and noise caused by changes in the attraction force between iron core discs, and also optimizing the overall height of the system, reducing the apparatus transportation cost, and improving the transportation flexibility. In addition, the structure avoids the additional noise generated by the vibration of a conventional positioning cylinder, enhances the reliability and adaptability of system operation, and provides an efficient and stable solution for the design and application of high-voltage and ultra-high-voltage reactors.
