Abstract

The invention discloses a high-voltage transformer. Fixing frames are fixed to the lower surface of an upper iron yoke. Threaded sleeves are arranged in the fixing frames, and threaded rods penetrate through the threaded sleeves. The threaded rods are sleeved with locking nuts, and the locking nuts are located below the threaded sleeves. Driving discs are arranged at the tops of the threaded rods. Driving devices are arranged on the fixing frames. The output ends of the driving devices are connected with the driving discs through belts. Sliding blocks are arranged at the bottoms of the threaded rods. The upper surfaces of upper pressing plates make contact with the lower surfaces of fixing blocks. Sliding sleeves are fixed in the fixing blocks. The sliding blocks slide in the sliding sleeves. Elastic components are arranged between the bottoms of the sliding blocks and the bottom surfaces inside the sliding sleeves. According to the high-voltage transformer, automatic pressing devices can exert pressure on the upper pressing plates continuously, so that it is guaranteed that a whole winding will not become loose between the upper iron yoke and a lower iron yoke, and it is also guaranteed that coils will not get loose between the upper pressing plates and lower pressing plates.

Description

technical field [0001] The invention relates to a transformer, in particular to a high-voltage transformer with good anti-short circuit performance. 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 the anti-short circuit performance is one of the most important. 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 proof performance of the transformer, which affects the normal operation of the entire electronic system. Contents of the invention [0003] In view o...
