Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment: as shown in Figure 1, Figure 2 and Figure 3, a kind of voltage transformer major insulation barrel structure of the utility model, including master
Insulating cylinder 1, annular core 2 and mounting bracket 3, the side ring set at 2 top of annular core is in the inside of insulating cylinder 1, mounting bracket 3
It is fixed at the bottom of annular core 2, annular core 2 is made of the first C-shaped iron core 13 and the second C-shaped iron core 4, the first C-shaped
It is provided with fixed block 5 on the outside of the junction of iron core 13 and the second C-shaped iron core 4, is respectively arranged with matching at the top of two fixed blocks 5
The screw rod 6 and gasket 7 of conjunction, mounting bracket 3 are made of mounting blocks 8 and mounting seat 9, and mounting blocks 8 are fixed at annular core 2
Bottom, mounting blocks 8 and mounting seat 9 are connected together.
Wherein, the inside two sides of mounting blocks 8 are respectively arranged with a U-shaped bar 11, are provided with compression between two U-shaped bars 11
Spring 12 drives compressed spring 12 to contract by squeezing U-shaped bar 11, at this moment mounting blocks 8 as in groove 10, U-shaped bar
11 engage with the card hole of 10 two sides of groove, realize being connected together between mounting seat 9 and mounting blocks 8.
Wherein, the top of mounting seat 9 opens up fluted 10, and the two sides of groove 10 offer and 11 phase of U-shaped bar respectively
The card hole matched, four edges of mounting seat 9 offer screw hole 14, and through-hole screw hole 14 is mounting bracket 3 and installation panel
Fixed setting.
Wherein, the first C-shaped iron core 13 is identical with 4 size shape of the second C-shaped iron core, the first C-shaped iron core 13 and the second C-shaped iron
4 shape of core is identical, equal in magnitude, and the both ends of the first C-shaped iron core 13 and the second C-shaped iron core 4 are arranged with insulation sleeve, by being arranged
Insulation sleeve can be avoided the single iron core dispersion of the first C-shaped iron core 13 and the second C-shaped iron core 4.
Wherein, the outer surface of annular core 2, mounting bracket 3, screw rod 6 and gasket 7 are isolation material, are not interfered with
The normal work of voltage transformer.
When work, mounting seat 9 is fixed by bolt and fixed panel, squeezes U-shaped bar 11, U-shaped bar 11 pushes compression
