For achieving the above object, the technical solution of the utility model is as follows:
A kind of dry-type transformer coil compressing structure, it comprises folder and cushion block, and the side of described folder connects iron core, and described folder offers endoporus, and fastening bolt arrives on described cushion block through described endoporus, described cushion block coil pressing; The internal diameter of described endoporus is greater than the external diameter of described fastening bolt, and be provided with nut in described endoporus, described fastening bolt coordinates described nut; The contact jaw of described fastening bolt and described cushion block is hemisphere projective structure, and the end face that described cushion block contacts with described fastening bolt is provided with the hemisphere coordinated with hemisphere projective structure and caves in.
In a preferred embodiment of the present utility model, comprise further, described hemisphere projective structure and hemisphere cave in and are directly provided with metal screen layer.
In a preferred embodiment of the present utility model, comprise further, described metal screen layer and described hemisphere cave in integrally, and described metal screen layer is embedded into described hemisphere sunk surface, the hemisphere face of described metal screen layer and hemisphere projective structure even contact.
In a preferred embodiment of the present utility model, comprise further, the upper end of described fastening bolt has at least one nut to coordinate the described folder of compression.
In a preferred embodiment of the present utility model, comprise further, the cross section of described folder is concave shape, and described endoporus is opened in a groove walls of described folder, and described iron core is fixed on the groove bottom wall of described folder.
The beneficial effects of the utility model are:
One, dry-type transformer coil compressing structure of the present utility model, by establishing nut in perforate on folder, solving the short-life drawback of traditional self-tapping bores, improve useful life, relatively cost-saving.
Two, dry-type transformer coil compressing structure of the present utility model, coordinate the fastening bolt of special construction, the hemisphere projective structure of fastening bolt bottom and the hemisphere of cushion block respective outer side edges of caving in uses, not only add the steadiness that fastening bolt is against cushion block, and be also provided with metal screen layer between them, enhance insulation property, improve coefficient of safety.
