Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] At present, high-power converters are always installed on locomotives. Since different locomotives have different requirements for the appearance and weight of converters, different converters have different requirements for converter boxes. different. The traditional converter box is usually a frame structure, and the converter box c...

Abstract

The invention provides a converter box and a converter. The converter box includes a support frame and a plurality of structural plates, the support frame includes a plurality of mutually spliced ​​support columns, and the plurality of support columns are arranged at intervals to enclose a space for accommodating electrical components, and two adjacent support columns The columns are welded; the multiple structural plates include the protective plate located on the outer surface of the supporting frame, and the protective plate and the supporting frame are riveted by riveting parts. After the converter adopts the above-mentioned converter box, the converter box can have sufficient strength to support the weight of the electrical components inside the converter, which is conducive to the reasonable arrangement of electrical components inside the converter box , so that the converter box can better protect the electrical components inside the converter from being squeezed, thereby improving the reliability of the converter, and improving the aesthetics of the converter box.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a converter box and a converter. Background technique [0002] At present, high-power converters are always installed on locomotives. Since different locomotives have different requirements for the appearance and weight of converters, different converters have different requirements for converter boxes. different. The traditional converter box is usually a frame structure, and the converter box contains various electrical components of the converter, so the converter box must have sufficient strength to support the various electrical components inside the converter the weight of. [0003] In the prior art, carbon steel plates are welded or galvanized steel plates are riveted to meet the requirements for the strength of the converter box to carry the weight of various electrical components inside the converter. However, if the converter box is welded solely with carbon steel plates, it ...
