Short circuit prevention high-voltage transformer

Abstract

The invention discloses a short circuit prevention high-voltage transformer. Iron cores are axially arranged between an upper iron yoke and a lower iron yoke; windings are arranged around the iron cores; a compression device is arranged between the upper iron yoke and each upper pressing board. Each compression device comprises a fixing frame, a threaded sleeve, a screw rod, a locking nut, a sliding block, a fixed block, a sliding sleeve, an elastic component and a handle, wherein the fixing frame and the lower surface of the upper iron yoke are fixed; the threaded sleeve is arranged in the fixing frame; the screw rod penetrates through the threaded sleeve and is sleeved with the locking nut; the locking nut is located below the threaded sleeve; the sliding block is arranged at the bottom of the screw rod; the upper surface of each upper pressing board makes contact with the lower surface of the corresponding fixed block; the sliding sleeve is fixed in the fixed block; the sliding block slides in the sliding sleeve; the elastic component is arranged between the bottom of the sliding block and the inner bottom face of the sliding sleeve; the handle is arranged on the top of the screw rod. The quality of the short circuit prevention high-voltage transformer is effectively ensured, the short circuit prevention capacity of the short circuit prevention high-voltage transformer is improved, and market requirements are met.

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...
