Embodiment
1 and 2 understand that the utility model is specifically related to a kind of antidetonation dry-type transformer, and its concrete structure includes with reference to the accompanying drawings
The fixing device of iron core 2, coil 10 and secured core 2 and coil 10, its coil 10 winding iron core 2, the two ends of iron core 2 with
Fixing device is connected.2~4 iron cores 2 are set in general fixing device, transformer is formed.In order that this dry-type transformer
Swung to earthquake-resistant, with shock-resistance features, the fixing device to iron core 2 is improved.
Fixing device in the utility model is designed as frame structure, wherein connected in the upper end of iron core 2 using upper back timber 4,
The lower end of iron core 2 is connected using lower bottom girder 11, and one is connected as by two ends for the tie rod 3 of screw thread in upper back timber 4 and lower bottom girder 11
Body, such iron core 2 and upper back timber 4, lower bottom girder 11 are combined together, and are formed integral frame structure, are set in the lower section of lower bottom girder 11
Installing two is used for fixed base anchor 1, and base anchor 1 is distributed in the two ends of lower bottom girder 11, and is arranged vertically with lower bottom girder 11,
Base anchor 1 is provided with anchor (bolt) hole.Adjusted in the structure using the screw thread on tie rod 3 upper back timber 4 and lower bottom girder 11 it
Between tightness, it is ensured that upper do not produced between back timber 4, lower bottom girder 11 and iron core 2 is rocked, and can resist vibrations.
In order that the utility model can resist larger swing, upper back timber 4 and lower bottom girder 11 are designed as two side by side
Set, two upper to be connected between back timber 4 or lower bottom girder 11 by the cross bolts of connecting plate 9, the distance between two upper back timbers 4 with
The distance between two lower bottom girders 11 are equal.The upper and lower side of iron core is clamped using upper back timber 4 and lower bottom girder 11, in order to avoid iron core
Slip, fixed between iron core and upper back timber 4, lower bottom girder 11 with bolt, so whole framework can be increased on thickness, have
There is third dimension, and stably, iron core can be fixed and more consolidated.
