Problems solved by technology

[0004] There are at least the following problems in the prior art: the lifting lugs are only welded to the skin plate of the cabinet body. Since the thickness of the skin plate is relatively thin, the weld seam will be particularly thick, which will cause deformation of the skin plate due to high temperature; and The leather needs to withstand a lot of pressure and is easily damaged

Abstract

The invention provides a cabinet used for a converter, the converter and a rail vehicle. The cabinet used for the converter comprises a wallboard assembly and skin, wherein the wallboard assembly comprises a plurality of first wallboards and a plurality of second wallboards, and the first wallboards and the second wallboards define a cavity in an enclosed mode; the first wallboards and the second wallboards are wrapped with the skin. Lugs extending outwards are integrally formed at the two ends of each first wallboard and are wrapped with the skin, each lug is provided with a first installation hole, and the skin is provided with second installation holes corresponding to the first installation holes. According to the cabinet, the lugs and a cabinet body are integrated, the structural strength of the cabinet is improved, the service life of the skin is prolonged and hoisting installation performance of the cabinet is improved.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a cabinet body for a converter, a converter and a rail vehicle. Background technique [0002] At present, with the rapid development of rail transit, the demand for traction equipment is also increasing. The core components such as traction converters and auxiliary converters of subways and bullet trains are suspended at the bottom of the car body through their own cabinets. Many electrical devices are placed inside their cabinets. These devices interact and restrict each other, which is the guarantee for the realization of the electrical performance of the converter. The strength and vibration characteristics of the cabinet structure will directly affect the work of the electrical components in the cabinet, and even affect the running safety of the train. There are many kinds of hanging weights, ranging from hundreds of kilograms to several tons. Since the vehicle will encounter variou...
