Embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1 and Fig. 2, the cuboid box body that a kind of oil immersed amorphous alloy iron core transformer bits collecting box 100 that the utility model provides is a upper surface open.

Referring to Fig. 3, bits collecting box 100 is set in the opening part unshakable in one's determination 210 of Amorphous Alloy Core Transformer device body bottom, and it is the chip unshakable in one's determination dropping from opening part 210 unshakable in one's determination for collecting Amorphous Alloy Core Transformer.

Bits collecting box 100, the diamond paper that is specifically 0.25mm by thickness is made, because diamond paper toughness is very high, in the time being provided with the oil immersed amorphous alloy iron core transformer of bits collecting box 100 and putting into oil tank of transformer 220, bits collecting box 100 can not be permeated and be corroded, and can not make chip unshakable in one's determination come off in bits collecting box 100, has improved the fail safe of Amorphous Alloy Core Transformer, and it is low that it has cost, the advantage of long service life.

The opening size of bits collecting box 100 is 1030mm × 350mm, be highly 130mm, like this in the time that bits collecting box 100 is set in opening part 210 unshakable in one's determination, its opening size just with amorphous alloy core width and consistency of thickness, and be highly also consistent with opening part 210 unshakable in one's determination, just encase opening part 210 unshakable in one's determination, do not waste so too much making material, save production cost, also can with Amorphous Alloy Core Transformer perfect cooperation, do not affect the work of Amorphous Alloy Core Transformer.
