First fixed plate is bonded with second fixed plate with the iron core web.
Preferably, the protective plate is raised laterally, and a cavity is formed between the iron core web；The iron core web
On nut be located in the cavity.
Preferably, the quantity of the through hole is two；One through hole is set in first fixed plate；Described second
Another through hole is set in fixed plate.
Preferably, the quantity of the unthreaded hole on the iron core web is two；The quantity of screwed hole on the iron core fagging
For two；The quantity of the insulated bolt is two.
Preferably, the insulation protective board is made up of insulating paper.
Preferably, the insulated bolt includes nylon bolt.
Based on above-mentioned technical proposal, transformer insulated safeguard structure provided by the utility model, mainly including insulation protective board
And insulated bolt, insulation protective board are covered on the nut on iron core web, and it is threadedly coupled by insulated bolt with iron core fagging
So that insulation protective board is fixedly mounted on iron core web.By the way that insulation protective board is covered in into nut raised on iron core web (gold
Belong to wedge angle) on, insulating protection space is formed in nut side, by the electric field shielding of the nut (metal wedge angle) of projection, Jin Erzeng
Insulation distance on big raised nut (metal wedge angle) and bushing between voltage equalizing ball, realizes and is not increasing transformer
The normal operation of transformer on the premise of volume, while save the manufacturing cost of transformer.
