Method used

A kind of anti-short-circuit high-voltage transformer of the present invention, during use, according to the installation mode of general transformer, first iron core is arranged on the lower iron yoke, puts on winding, then installs upper iron yoke, then lasts bakelite Place the insulating adjustment piece and the lower bakelite spacer under the spacer to detect the degree of compression. After compression, use the bakelite fasteners to fix the upper bakelite spacer, the lower bakelite spacer and the insulation adjustment piece; the compression spacer device Applying pressure to the upper pressing plate, one is to ensure that the entire winding is not loose between the upper iron yoke and the lower iron yoke, and the second is to ensure that the coil is not loose between the upper pressing plate and the lower pressing pl...

Abstract

The invention discloses a short circuit prevention high voltage transformer. The short circuit prevention high voltage transformer comprises an iron core, an upper iron yoke, a lower iron yoke and a winding. The winding comprises a coil, an upper pressing plate, a lower pressing plate and a compression cushion block device. The compression cushion block device comprises a fixing frame and a cushion block assembly. The cushion block assembly comprises an upper bakelite cushion block, a lower bakelite cushion block, an insulation adjusting sheet and a bakelite fastener. The fixing frame and the lower surface of the upper iron yoke are fixed. The upper bakelite cushion block and the lower surface of the fixing frame are fixed. The lower surface of the lower bakelite cushion block makes contact with the upper surface of the upper pressing plate. The insulation adjusting sheet is arranged between the upper bakelite cushion block and the lower bakelite cushion block. The upper bakelite cushion block, the lower bakelite cushion block and the insulation adjusting sheet are fixed through the bakelite fastener. According to the short circuit prevention high voltage transformer, the compression cushion block device can continuously apply pressure on the upper pressing plate; on the one hand, it is ensured that the whole winding does not loosen between the upper iron yoke and the lower iron yoke; on the other hand, it is ensured that the coil is not disengaged between the upper pressing plate and the lower pressing plate.

[0015] The present invention will be described below with reference to the drawings.

[0016] As attached Figure 1-3 The short-circuit-resistant high-voltage transformer of the present invention shown includes an iron core 1, an upper iron yoke 2, a lower iron yoke 3 and windings; the iron core 1 is axially arranged on the upper iron yoke 2 and the lower iron yoke 3; the winding is arranged around the iron core 1; the winding includes a coil 4, an upper pressing plate 5, a lower pressing plate 6 and a pressing pad device; the coil 4 is arranged around the iron core 1 on the upper pressing plate 5 and the lower pressing plate 6 between; the compression pad device is provided between the upper iron yoke 2 and the upper pressure plate 6; the compression pad device includes a fixing frame 7 and a pad assembly; the pad assembly includes an upper bakelite pad 8. Lower bakelite block 9, insulation adjustment sheet 10 and bakelite fastener 11; the fixing frame 7 is fixed to the lower surface of the upper iron yoke 2; the upper bakelite block 8 is fixed to the lower surface of the fixing frame 7 The lower surface of the lower bakelite block 9 is in contact with the upper surface of the upper pressure plate 5; the upper bakelite block 8 and the lower bakelite block 9 are provided with an insulating adjustment sheet 10; the upper bakelite block 8, The lower bakelite block 9 and the insulation adjustment piece 10 are fixed by bakelite fasteners 11.

[0017] In the above-mentioned short-circuit-resistant high-voltage transformer, generally, two spacer assemblies are provided.

[0018] The short-circuit-resistant high-voltage transformer of the present invention, when used, according to the general transformer installation method, first set the iron core on the lower iron yoke, cover the windings, then install the upper iron yoke, and then install the upper bakelite block Place the insulation regulating piece and the lower bakelite block below to detect the degree of compression. After compression, use bakelite fasteners to fix the upper bakelite block, lower bakelite block and insulation regulating sheet; the compression block device is opposed to the upper pressure plate Applying pressure, one is to ensure that the entire winding is not loosened between the upper iron yoke and the lower iron yoke, and the other is to ensure that the coil is not loosened between the upper pressing plate and the lower pressing plate, which can effectively ensure the quality of the high-voltage transformer and improve the The short-circuit resistance of the voltage transformer; at the same time, because the spacer components are made of insulating materials, the electric strength is large, and the distribution in high field strength is convenient, and the insulation distance and other parameters are easy to guarantee; and the operation is convenient, which shortens the operation time and reduces the winding cost The damp time again ensures the quality of the high-voltage transformer.

[0019] In the above-mentioned short-circuit-resistant high-voltage transformer, there are a plurality of compression devices in an annular symmetrical array around the iron core, which ensures the uniformity of pressure and can prevent the voltage deviation of the winding.

[0020] For the above-mentioned short-circuit-resistant high-voltage transformer, due to the large force-receiving area of the cushion block component, when only six compression devices are required, the compression effect is the best, and the use effect of the high-voltage transformer is also the best.

[0021] The above-mentioned embodiments are only to illustrate the technical concept and features of the present invention, and their purpose is to enable those familiar with the technology to understand the content of the present invention and implement it, and cannot limit the scope of protection of the present invention. All equivalent changes or modifications made by the essence should be covered by the protection scope of the present invention.
