Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a dry iron core transformer and a use method thereof. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] In the dry-type iron core transformer in the prior art, when the ground is uneven when pushing the transformer body, the roller will rise and fall, compressing the first spring, so that the first spring compresses the limit plate, and then the limit plate compresses the second spring, weakening the fluctuation amplitude of the roller, thereby weakening the vibration of the fixed body, that is, reducing the vibration of the transformer body, reducing the possibility of damage to the transformer body during the movement process, and moving the rotating shaft to the required position to restore the rotating shaft to the original position, fixing the position of the connecting frame, that is, fixing the position of the transformer body after moving, so that the transformer body is easy to move and the position after moving can also be fixed more stably;
