Short-circuit prevention high voltage transformer

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.

Description

technical field [0001] The invention relates to a transformer, in particular to a short-circuit resistant high-voltage transformer. Background technique [0002] With the development of power technology, the capacity of transformers is getting larger and higher, and the voltage level is getting higher and higher. The role of high-voltage transformers in power systems is prominent. Therefore, the safe operation of high-voltage transformers is related to the overall situation of electronic systems. The safe operation of high-voltage transformers is affected by many factors, among which short-circuit resistance is an important one. Due to the unreasonable structure of the previous transformers, the windings are easy to loose, and the coils are easy to loosen, resulting in poor short-circuit resistance of the transformer, which affects the normal operation of the entire electronic system. Contents of the invention [0003] In view of the above-mentioned existing technical pr...
