Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] The present invention provides a locomotive rectifier device, such as figure 1 As shown, it is an internal structure diagram of the locomotive rectifier of the present invention. figure 1 It can be seen that the locomotive rectifier device in the present invention includes a cabinet 1, three terminals 2, three fast fuse 3, six diode 4, two output terminals 5, and nine radiator 6. Such as Figure 4 As shown, the electrical principle diagram of the motor vehicle rectifier device of the present invention, by Figure 4 It can be seen that the rectifier device of the present invention is a three-phase bridge rectifier device, which is divided into three parts by U, V, and W.

[0026] Such as figure 2 As shown, it is an exploded view of the rectifier device of the present invention, and the cabinet in the motor vehicle rectifier is a split type, that is, three sub-cabinets; i...

Abstract

The invention discloses a locomotive rectifier, which comprises a cabinet body, the cabinet body includes three sub-cabinets, each sub-cabinet is provided with two diodes in series and three radiators, and the diodes and radiators are arranged alternately; each sub-cabinet The outer wall of the cabinet is provided with a terminal and a fast fuse, one end of the fast fuse is connected to the terminal, and the other end of the fast fuse is connected between two diodes; the upper part of the cabinet is also provided with two output terminals, The two diodes in each sub-cabinet correspond to and connect to the two output ends respectively. The rectifier cabinet body of the present invention is formed by connecting and fixing three sub-cabinets with the same structure and size. The rectifier cabinet body of the present invention is changed from an integral type to a split type. It is difficult and time-consuming for personnel to assemble, install and maintain, and it also facilitates transportation and reduces production costs in many aspects; the present invention improves work efficiency while realizing electrical functions.

Description

Technical field [0001] The present invention belongs to the field of rectifier, and more particularly to a rectifier device applied to a locomotive with a rectifier cabinet. Background technique [0002] The HXN3 locomotive is a large-power exchange-transmitted internal combustion control vehicle jointly developed by Dalian Locomotive Vehicle Co., Ltd. and US EMD. The main stream system is one of the key components of the locomotive traction system. There are two sets of rectifiers in the whole vehicle. Table steering frame. [0003] However, existing rectifiers typically use three-phase full-control bridge rectification, each bridge arm consists of five bolt-type diodes, and each of the engrave is string with a fast fuse. Therefore, each set of rectifiers consists of 30 bolt diodes, fifteen fast fuses, radiators, and copper rows. However, due to the increase in the use of locomotives, the resistance of the fuse will change, and the same bridge arm is in parallel with the five bo...
