Problems solved by technology

[0005] (c) Inconvenient installation and maintenance
Many rectifiers are inconvenient for installation and maintenance due to structural design without modularization and convenience considerations. Sometimes in order to repair a component or component, many other components need to be disassembled, which not only requires a lot of work, but also Have a serious impact on the reliability and overall life of the system

Abstract

The invention discloses a thyristor rectifier module. The thyristor rectifier module comprises a machine box, a thyristor rectifier unit, a pulse amplifying unit, a resistance-capacitance absorbing unit, a display unit, an alternating-and-direct current busbar, a large-current terminal and the like. The thyristor rectifier module is of an embedded structure. The machine box is an outer shell. The thyristor rectifier module of the embedded structure has the advantages that the universality is stronger, the number of external connectors is smaller, the appearance is more attractive, heat radiating can be achieved easily, and diversified products can be generated through different combination and matching modes to meet requirements of different users. The thyristor rectifier module is applicable to systems, such as excitation systems, automatic control systems and testing systems, which adopt three-phase full-controlled thyristors for rectification and have exciting currents smaller than 20 A.

Description

technical field [0001] The invention relates to a thyristor rectifier module, which is suitable for the generalization, integration and modularization of excitation systems, automatic control systems, test systems and other systems that adopt three-phase fully-controlled thyristor rectification with an excitation current of 20A or less. The three-phase AC power supply is transformed into a suitable pulsating DC power supply through a three-phase fully-controlled thyristor rectifier module. Background technique [0002] As customers have more and more personalized demands for excitation products, excitation products are showing a trend of diversification and customization, resulting in high R&D and maintenance costs, and poor product consistency, reliability, and maintainability. Realizing the modularization and standardization of excitation products can greatly improve the efficiency of product research and development, reduce costs, improve product manufacturability, and be...
