High-power rotating rectifier module

Abstract

The invention discloses a high-power rotating rectifier module. The high-power rotating rectifier module comprises a radiating base made of metal, wherein the top end of the radiating base is bonded with the lower end surfaces of two rectifier diodes; the upper end surface of each rectifier diode is bonded with the lower end surface of one radiating pressure block; radiating channels are respectively formed in all the radiating pressure blocks; a wind inlet port on the upper end surface of each radiating pressure block is connected with an air outlet of one radiating wind pipe; the outer side walls of all the radiating wind pipes are coated with butterfly springs; the bottom end of the butterfly spring at the lower part is butted to the upper end surfaces of the radiating pressure blocks; the top end of the butterfly spring at the upper part is butted to the lower surfaces of connecting pressure plates; the left and right ends of the connecting pressure plates are respectively in fixed connection with the radiating base in an electric insulating manner by a plurality of connecting bolts. The invention aims to provide the high-power rotating rectifier module which has the advantages of small size, compact structure, low manufacturing cost, high convenience for installation and use, good radiating performance, long service life, low fault occurrence rate and high reliability and can be provided with the rectifier diodes.

Description

technical field [0001] The invention relates to a high-power rotary rectification assembly. Background technique [0002] In the past 10 years, due to the low efficiency and high pollutant emission of small and medium power generating units, the relevant national departments have encouraged new power plants to be large (that is, to encourage the installation of units above 1000MW) and to limit small (units below 300MW). The components of the rotating rectifier diode used in the exciter of synchronous generators above 1000MW are large in size, heavy in weight, have many fixed points, and poor heat dissipation, resulting in short service life, high failure rate, and low reliability. Multiple rectifier diode assemblies are connected in parallel, so it is not suitable for use on exciters of this power level. Contents of the invention [0003] The purpose of the present invention is to provide a small size, compact structure, low cost, convenient installation and use, good hea...

[0002] In the past 10 years, due to the low efficiency and high pollutant emission of small and medium power generator sets, the relevant national departments have encouraged new power plants to be large (that is, to encourage the installation of units above 1000MW) and to limit small (units below 300MW). The components of the rotating rectifier diode used in the exciter of synchronous generators above 1000MW are large in size, heavy in weight, have many fixed points, and poor heat dissipation, resulting in short service life, high failure rate, and low reliability. Connect multiple rectifier diode components in parallel, so it is not suitable for use on exciters of this power level
