Embodiment 1
[0032] An iron core limiting device of a dry-type amorphous alloy iron core transformer, comprising a slot-shaped clip 1, a clip insulation 2, a clip sealing plate 3 made of a hard insulating material, and an air cushion 4; the slot-shaped clip 1. It includes an upper clip 11, a lower clip 12 and two side clips 13, 14; the number of the air cushions 4 is four, and in the use state, they are respectively located on the upper clip 11, the lower clip 12, and the two side clips between the clip insulation 2 and the amorphous alloy iron core 0 inside the parts 13 and 14; the air cushion 4 includes an air bag 41, an inflating and deflating nozzle 42 and an on-off valve 43, wherein the inflating and deflating nozzle 42 is located on the air bag 41, and the The on-off valve 43 is located on the inflation and deflation nozzle 42; the upper clip 11 and the webs of the two side clips 13, 14 are drilled with a hole matching the inflation and deflation nozzle 42; the clip Insulation 2 is a...
Embodiment 2
[0034] A method for limiting the position of a transformer core, comprising the following steps:
[0035] a. Install clip insulation 2 on the inner side of slot clip 1;
[0036] b. Install the air cushion 4 on the inner side of the clamp insulation 2;
[0037] c. Fill the air cushion 4 with about half of the gas in advance (it can also be other amounts of gas according to the actual situation);
[0038] d. Assemble the slot clip 1 on the amorphous alloy core 0 that sets the transformer winding 5;
[0039] e. Fix the clip sealing plate 3 on the groove clip 1, and fix the amorphous alloy iron core 0 through the clip sealing plate 3;
[0040] f. Inflate the air cushion 4, and measure the sound level of the dry-type amorphous alloy iron core transformer, and adjust the amorphous alloy iron core 0 according to the sound level measurement until the sound level measurement is qualified.
