A 1000kw power class pure electric AC drive shunting locomotive

Abstract

The invention discloses a 1000kW-power-grade pure electric alternating current driving shunting locomotive and relates to the field of rail transportation. The locomotive is divided into a locomotive main body and a lower structure from top to bottom; the locomotive main body comprises an auxiliary room, a first storage battery room, an electric room, a second storage battery room, a cab and a rear machine room from right to left; the lower structure comprises two bogies, and an auxiliary converter cabinet and a vehicle-mounted charging transformer which are arranged in the middles of the two bogies respectively; the locomotive main body is seated on the two bogies through side bearings; the bogies are provided with wheel pairs; a traction motor provides power to the wheel pairs; an output shaft of the traction motor drives the wheel pairs through a traction gear so that power transmission is realized; the traction motor is driven by electric energy provided by the first storage battery room and / or the second storage battery room so that a zero-emission environment-friendly degree is realized; power driving also has the characteristics of no mechanical response time, capability of outputting high energy in short time, and extremely high locomotive acceleration performance.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a pure electric AC drive shunting locomotive with a power level of 1000kW. Background technique [0002] At present, domestic railway stations and yards undertake shunting diesel locomotives (shunting diesel locomotives) and internal combustion locomotives (industrial and mining diesel locomotives) that undertake railway transportation tasks in steel, petrochemical, coal, power plants, ports, wharves and other industrial and mining enterprises The characteristics of the work are: [0003] 1) The locomotive changes direction, starts, accelerates and brakes frequently; [0004] 2) Locomotive load changes frequently; [0005] 3) The full load working time of the diesel engine only accounts for 10%; [0006] 4) about 50% of the working time is no-load; [0007] 5) The average power used by the diesel engine during the whole working period is only 1 / 3~1 / 2 of the rated power. ...

AI Technical Summary

Problems solved by technology

[0003] 1) The locomotive changes direction, starts, accelerates and brakes frequently;

[0004] 2) Locomotive load changes frequently;

[0005] 3) The full load working time of the diesel engine only accounts for 10%;

[0009] 1) The power potential of the diesel engine cannot be fully utilized;

[0010] 2) The no-load fuel consumption waste of diesel is serious;

[0011] 3) Frequent changes in the load of the diesel engine cause insufficient diesel combustion, black smoke, high fuel consumption, high carbon content in the exhaust gas, and serious environmental pollution

[0012] It can be seen that there are many problems in traditional industrial and mining shunting locomotives, which affect economic development and people's normal life. Therefore, it is very important to develop a locomotive that has no pollution, no noise, zero emissions, no mechanical reaction time, and can output high energy in a short time. far-reaching
