High-power high-speed rotating rectifier assembly

Abstract

The invention provides a high-power high-speed rotating rectifier assembly. The high-power high-speed rotating rectifier assembly comprises a flat plate type rectifier and further comprises a structural frame, a cross-over block, a lower copper bar, an upper copper bar, a leveling cushion block, a disk spring, an inverted T-shaped guide post, a ball head bolt, an anode aluminum block and a cathode screw. The structural frame is formed by connecting a plurality of conductive screws with conductive screw holes in an upper pressing plate and a lower pressing plate, and the appearance of the structural frame is similar to a cylinder. The lower copper bar and the cross-over block are respectively and wholly of a T shape, and the lower portion of the cross-over block is fixed to a trapezoid through hole in the center of the lower pressing plate in an interference fit mode. A traditional bolt type rectifier is abandoned, a flat plate type rectifier tube is boldly adopted as a core device, a press-fitting structure is ingeniously designed according to the structural features of the device, it is guaranteed that the flat plate type device can still normally work on high-speed rotating occasions, and therefore the problem of application of the flat plate type rectifier to the high-speed rotating occasions is solved.

Description

technical field [0001] The invention relates to the field of generator excitation systems, in particular to a high-power high-speed rotating rectifier assembly. Background technique [0002] In the generator excitation system, the high-speed rotating AC excitation generator outputs alternating current, which must be rectified and then output to the main generator for excitation. In this system, a core component is the rectifier, which operates coaxially with the generator, so It is required to withstand high centrifugal force. [0003] Rotary rectifier is a kind of rectifier used in rotating occasions. The more common application form is rotating three-phase bridge rectifier, that is, the three-phase bridge rectifier and the generator run coaxially. After the alternating current is rectified by the rectifier, the output direct current is supplied to the main generator. excitation. Because it is used in high-speed rotating applications differently from ordinary rectifiers, ...

AI Technical Summary

Problems solved by technology

The electrical performance parameters of the flat-plate rectifier can meet the application requirements of high power, but the structure cannot meet the application requirements, and has never been successfully applied to high-speed rotation occasions, so special design is required according to its structural characteristics
