Problems solved by technology
Because the circuit structure and control of the three are different, the interfaces of the products are various and cannot be interchanged.
[0004] (2) The volume is too large
The flat-plate thyristors used in many rectifiers are formed by crimping with profile radiators, which makes the volume too large and difficult to install and disassemble.
[0005] (3) Power serialization is difficult
[0006] (4) Inconvenient installation and maintenance
Due to the lack of modularization and convenience considerations in the structural design of many rectifiers, it brings great inconvenience to installation and maintenance. It is often necessary to dismantle many other components or components in order to maintain one component or component. Have a serious impact on the reliability and overall life of the system

The invention discloses a specific implementation mode of a modularization thyristor rectifying unit, which comprises a rectifying unit, a resistance-capacitance absorbing unit, support brackets and a control box, wherein the modularization thyristor rectifying unit is in a draw type structure; the rectifying unit comprises thyristor components and a heat radiator; the thyristor components are distributed and arranged on the heat radiator; the rectifying unit is arranged at the bottom of the modularization thyristor rectifying unit; the resistance-capacitance absorbing unit is arranged in the middle of the modularization thyristor rectifying unit; the support brackets are fixed around the heat radiator of the rectifying unit and used for supporting and fixing the middle upper layer of the modularization thyristor rectifying unit; and the control box is fixed at the uppermost layer of the modularization thyristor rectifying unit. The modularization thyristor rectifying unit of the draw type structure has the advantages of stronger generality, less external interface, more beautiful appearance and selectable heat radiation mode, and can meet the requirements of high modularization degree, high maintainability and convenient power expansion in the field of a modern industrial transmission converter by implementing the technical scheme described by the invention.
Description
technical field [0001] The invention relates to a thyristor rectifier unit, in particular to a generalized, integrated and modularized thyristor rectifier unit used in the field of industrial transmission converters for converting alternating current into appropriate direct current. Background technique [0002] Because the field of industrial transmission converters requires a high degree of modularization and high maintainability for its products. Currently commonly used situations are: [0003] (1) The degree of modularization is not high. Modularity is not considered, and the product is individually designed according to the size provided by the customer. Rectifier units used in industrial transmission converters are generally divided into diode rectifier units, thyristor rectifier units and four-quadrant rectifiers. Because the circuit structure and control of the three are different, the interfaces of the products are various and cannot be interchanged. [0004] (2...
