Abstract

The invention discloses a special 3-to-6 electric cabinet for a metro vehicle, which comprises a cabinet body, wherein the lower part of the cabinet body is provided with an opening, and the opening is provided with a detachable cover plate which is matched with the opening; three conducting copper bars are arranged inside the cabinet body in parallel, a first binding terminal is respectively arranged at the same ends of the three conducting copper bars, two second binding terminals are respectively arranged at the other end of each conducting copper bar, and an insulator is respectively arranged in the middle part of each conducting copper bar; and the lateral wall of the cabinet body at each first terminal binding terminal is provided with three first threading holes, and the lateral wall of the cabinet body at each second binding terminal is provided with 6 second threading holes. The special 3-to-6 electrical cabinet for the metro vehicle is low in cost and easy to maintain, ensures the production progress of the metro vehicle and greatly reduces the maintenance cost of the metro vehicle in the future.

Description

Technical field [0001] The invention relates to a cable connection device on a rail vehicle, specifically, a 3-to-6 electrical box dedicated to a traction motor of a subway vehicle, which can divide a three-phase power line into two lines and supply different traction motors respectively. Background technique [0002] Starting from Nanjing Metro Line 2, a three-to-six-way cable connector has been added between the traction inverter and the traction motor of the subway vehicle to divide the three power lines from the traction inverter into six, and then separate them Two different traction motors are supplied. [0003] This change is small, but because the connector is designed by DEUTSCH, the import cycle is long and the price is extremely high, which seriously affects the production schedule of subway vehicles and greatly increases the maintenance cost of the subway company in the future. Summary of the invention [0004] Objective of the invention: The objective of the present in...
