Embodiment Construction

[0013] The technical scheme of the invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as Figure 1-3 As shown, a six-split phase-shifting rectifier transformer includes a foot 1, a clamp 2, a coil 3, a terminal 4, an insulating plate 5, and a bent plate 6, and the clamp 2 includes an upper clamp and a lower clamp The lower clamp is installed on the foot; the coil 3 is arranged between the upper clamp and the lower clamp, and several terminals 4 are respectively arranged on both sides of the coil 3. There are three coils, including a high-voltage coil and a low-voltage coil. Coils, the high-voltage coils are on the back side of the transformer, and the low-voltage coils are on the front side of the transformer. The high-voltage and low-voltage coils are divided into six groups. The electrical safety performance of the body, the high and low voltage coils are divided into two sides, the upper and lower ends of the high voltage...

Abstract

The invention discloses a six-split shift-phase rectifier transformer. The six-split shift-phase rectifier transformer comprises bottom studs, clamps, coils, terminal blocks, an insulating plate and bent plates, wherein the clamps comprise an upper clamp and a lower clamp; the lower clamp is arranged on the bottom studs; the coils are arranged between the upper clamp and the lower clamp and comprise six groups of high voltage coils and six groups of low voltage coils, which are of six-split continuous structures; the high voltage coils are arranged on the back side of the transformer, the low voltage coils are arranged on the front side of the transformer, and a plurality of terminal blocks are respectively arranged on the two sides. According to the six-split shift-phase rectify transformer, the impedence of small groups of coils is in the equal deviation range.

Description

technical field [0001] The invention relates to a transformer, in particular to a six-split phase-shifting rectifier transformer. Background technique [0002] The phase-shifting rectifier transformer is a device specially designed to provide multi-phase rectification power for medium and high voltage frequency converters. Especially in today's mature development of frequency conversion speed regulation technology, the localization of phase-shifting rectifier transformers is urgently needed. The original dry-type phase-shifting rectifier transformer has a star connection on the high voltage side and a continuous triangular structure on the low voltage side. The low-voltage side realizes the transformation of the angle through the connection of the lead wires between the phases and the change of the number of turns, so as to achieve the purpose of phase-shifting rectification and suppression of harmonics. But this kind of transformer has a wide range of impedance deviation. ...
