Abstract

The invention relates to the field of installation of a high-voltage cable for rail transit converters, in particular to an intermediate transition terminal for rail transit converters. The intermediate transition terminal comprises an insulating bottom plate, a plurality of connecting copper bars and a plurality of wiring terminals. The connecting copper bars are arranged on the insulating bottomplate along the length direction of the insulating bottom plate. Each connecting copper bar is provided with at least two connecting holes. The insulating bottom plate is provided with connecting grooves in one-to-one correspondence with all the connecting holes. A stud is mounted in each connecting groove. Wiring parts of wiring harnesses are arranged in the wiring terminals in a penetrating manner. Each wiring terminal is provided with a mounting hole corresponding to any connecting hole. The stud body of at least one stud sequentially penetrates through the connecting holes of the connecting copper bars, continues to penetrate through the mounting holes of the wiring terminals and is fastened and connected through a nut gasket assembly. At least two wiring terminals are arranged on each connecting copper bar. According to the invention, the installation space of a high-voltage cable in a converter cabinet is saved, the electrical characteristics of high-voltage cable output are satisfied, and the electrical connection reliability is improved.

Description

technical field [0001] The invention relates to the field of installation of high-voltage cables for rail traffic converters, in particular to an intermediate transition terminal for rail traffic converters. Background technique [0002] In recent years, EMUs and locomotives in the field of rail transit tend to be lightweight and miniaturized. The converter cabinet is an important electrical component for the assembly of EMUs and locomotives. , High-efficiency technical indicators and requirements. Therefore, in the design of the overall layout, device layout, and electrical assembly of the converter in the rail transit field, it is necessary to consider the compact space and meet the design requirements of electrical performance. Under such a design background, relevant design inventions that can save design space in converters are particularly important. [0003] In the existing EMU and locomotive converters, the power module is an important device in the converter cabin...
