DETAILED DESCRIPTION
[0030] Based on the above structural features of the present application, the implementation methods of the present application are further described:
[0031] Reference Figures 1 to 10 This embodiment provides an iron core limiting assembly for a reactor, including a transmission rod 11 connected to the iron core 3 (for example, fixedly connected by bolts), a mounting plate 12 connected to the top outer surface of the reactor housing 2, a trigger push plate 13 connected to the transmission rod 11, a first pressure sensor 14 located above the trigger push plate 13, and a second pressure sensor 15 located below the trigger push plate 13. The lower part of the driving rod 4 is fixedly connected to the iron core 3 (for example, fixedly connected by bolts), and the upper part of the driving rod 4 is plugged into the plug hole at the top of the reactor housing 2. A linear drive is provided on the top outer surface of the reactor housing 2, and the output shaft of the linear drive is fixedly connected to the driving rod 4 by bolts. The linear drive drives the iron core 3 to move up / down through the driving rod 4 to meet the use requirements (for example, to lift the iron core 3 off the ground to increase insulation, or to change the relative position of the iron core 3 and the coil winding to adjust the inductance). When the iron core 3 moves up and down, it drives the transmission rod 11 to move up and down, and further drives the trigger push plate 13 to move up and down. When the first pressure sensor 14 or the second pressure sensor 15 is triggered by the trigger push plate 13 , an electrical signal is transmitted to a control system (eg, an external computer) to feed back the height information of the iron core 3 .
