The invention belongs to the technical field of temperature-resistant motors, and particularly relates to a control rod driving mechanism shielding motor, an inorganic insulating temperature-resistant winding and a preparation method. The inorganic insulating temperature-resistant winding comprises a coil and a shell, a first iron core is fixed to the shell, a plurality of tooth grooves which are evenly distributed in the radial direction, extend in the axial direction and are used for embedding the coil are formed in the first iron core, an insulating layer is laid in each tooth groove, a shielding spacer bush is arranged on the first iron core and on the opening side of each tooth groove, end plates are arranged at the two axial ends of the shell, the shell, the two end plates and the shielding spacer bush form a closed cavity used for packaging the first iron core and the coil, filler is poured into the closed cavity, and the coil is connected with a leading-out wire led out of the closed cavity. The inorganic insulating temperature-resistant winding can bear a high temperature of 500 DEG C. A control rod driving mechanism synchronous reluctance shielding motor based on the inorganic insulating temperature-resistant winding can operate at an ambient temperature of 350 DEG C without a cooling system.
Description
technical field [0001] The invention belongs to the technical field of temperature-resistant motors, and in particular relates to a shielded motor of a control rod drive mechanism, an inorganic insulated heat-resistant winding and a preparation method. Background technique [0002] The current temperature resistance grades of motors are Y, A, E, B, F, H, and C, and the corresponding maximum operating temperatures are 90°C, 105°C, 120°C, 130°C, 155°C, 180°C and above 180°C. There are seven levels in total. At present, most motors use organic polymer materials as insulation materials, and only a few organic insulations can reach Class C. For example, the temperature resistance level of polyesterimide is about 220°C, so it is difficult for organic insulation motors to reach higher temperatures. . [0003] The control rod drive mechanism of nuclear reactor is the key equipment to realize the functions of reactor start-up, power regulation, normal shutdown and accident shutdown...
