Technical Field

[0001] The invention relates to the technical field of mutual inductors, and in particular to a mutual inductor core transportation device. Background Art

[0002] The current transformer is an instrument that converts the large current on the primary side into the small current on the secondary side for measurement based on the principle of electromagnetic induction. The current transformer core is an important component of the current transformer, usually composed of a closed iron core and windings. As the core component of the current transformer, the transformer core needs to be transported efficiently and safely using a transportation device.

[0003] After searching the Chinese patent "A core for capacitive voltage transformer", the announcement number is "CN205027807U". This patent uses packing cardboard and packing tape to fix, which can ensure that each group of cores has consistent height and compression. A spring compression structure is added to the top of the product to ensure that the core does not loosen or deform during transportation. The device fixes the core through packing cardboard and polypropylene packing tape, and then compresses the core through a spring to prevent it from shaking and deforming. However, the fixing effect of the transformer core by the packing cardboard and polypropylene packing tape is not stable enough. During transportation, the device is prone to tilting and collapsing due to bumps during driving, which is not conducive to efficient and safe transportation of the transformer core, reducing the use effect of the device.
