Abstract

The invention discloses a traction converter for a low-floor vehicle. The traction converter comprises a cabinet body, wherein the cabinet body is divided into a front part and a rear part by a middle partition plate, a transmission control unit, a converter module, a plurality of current sensors and a plurality of voltage sensors are installed on the front part of the cabinet body, and an output contactor installation position is formed on the front part of the cabinet body; a CCU case and a fan are installed on the rear part of the cabinet body, and a circuit reactor is installed on the rear part of the cabinet body at the outlet side of the fan. The traction converter disclosed by the invention integrates the CCU case, realizes the module function of the existing double converters by one converter module, and solves the problem of an insufficient roof installation space of the low-floor vehicle; the traction converter disclosed by the invention is powerful in rainproof function, and capable of better avoiding the faults thereof.

Description

technical field [0001] The invention relates to the field of urban rail transit, in particular to a low-floor vehicle traction converter. Background technique [0002] Low-floor vehicles have a small space under the vehicle, and the traction converter and high-voltage electrical box are all installed on the top of the vehicle. Because pantographs and other equipment have been installed on the top of the vehicle, there is not enough space available. The existing traction converters are not highly integrated, and the CCU case and output contactors are installed outside the traction converter. The same traction converter cabinet cannot meet the requirements of permanent magnet motors and asynchronous motors at the same time, that is, it cannot One cabinet is multi-purpose, and the rainproof function is not strong, so it is prone to failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a highly integrated tractio...
