Background
The oil immersed amorphous alloy transformer has been widely applied to the reconstruction of rural power grids and urban power grids due to the advantages of small exciting current, low no-load loss, remarkable energy-saving effect and the like, and the proportion of the oil immersed amorphous alloy transformer in the national power grid collection is also getting larger and larger.
Because the oil immersed amorphous alloy transformer iron core is of an unstressed structure, the iron core is supported by the coil, and the coil is clamped by the clamping piece. With the special structure, when a product is short-circuited, great axial electrodynamic force can be generated inside the coil, namely the coil can move upwards as a whole. Because the coil is being held by the folder, can't remove, the coil can give the folder with the electrodynamic force transmission, and then causes whole transformer ware body drunkenness upwards, because the inside lead wire of product has been connected fixedly, such drunkenness can cause the inside lead wire fracture of product, causes the product to be unable to use. When the condition is serious, the internal short circuit of the product can be caused, and serious accidents can occur.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a fixing device for an oil-immersed amorphous alloy transformer body comprises a box body, wherein the transformer body is arranged in the box body, an upper clamping piece is arranged at the top of the transformer body, and a reinforcing plate is arranged on the upper surface of the upper clamping piece;
the top of the box body is provided with a box cover, and the box cover is connected with the box body through bolts; a plurality of positioning threaded pipes are arranged on the lower surface of the box cover, and positioning screws are connected to the positioning threaded pipes in a threaded manner; the positioning screw is provided with an adjusting nut matched with the lower surface of the positioning threaded pipe; the reinforcing plate is arranged on the adjusting stroke of the positioning screw.
Based on the above, the reinforcing plate is an inverted U-shaped reinforcing plate.
Based on the above, the upper clamping piece is a U-shaped upper clamping piece.
Based on the above, the two ends of the upper clamping piece are connected to the side wall of the box body through the fixing bolts.

Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Example 1
The embodiment provides an oil-immersed amorphous alloy transformer body fixing device, as shown in fig. 1 and fig. 2, the oil-immersed amorphous alloy transformer body fixing device comprises a box body 6, a transformer body 1 is arranged inside the box body 6, an upper clamping piece 7 is arranged at the top of the transformer body 1, and a reinforcing plate 2 is arranged on the upper surface of the upper clamping piece 7.
The top of the box body 6 is provided with a box cover 3, and the box cover 3 is connected with the box body 6 through bolts; a plurality of positioning threaded pipes 4 are arranged on the lower surface of the box cover 3, and positioning screws 5 are connected to the positioning threaded pipes 4 in a threaded manner; an adjusting nut matched with the lower surface of the positioning threaded pipe 5 is arranged on the positioning screw 5; the reinforcing plate 2 is arranged on the adjusting stroke of the positioning screw 5.
Wherein, reinforcing plate 2 is the reinforcing plate of shape of falling U. The upper clamping piece 7 is a U-shaped upper clamping piece. And two ends of the upper clamping piece 7 are connected to the side wall of the box body 6 through fixing bolts.
The upper surface of the upper clamping piece 7 is arranged in parallel with the box cover 3. The plurality of positioning threaded pipes 4 are symmetrically arranged with the center line of the case cover 3 as a symmetry axis.
