High-power alternating-current transmission shunting diesel locomotive

Abstract

The invention relates to the technical field of diesel locomotives, in particular to a high-power alternating-current transmission shunting diesel locomotive. The high-power alternating-current transmission shunting diesel locomotive comprises an upper body, a lower body, an auxiliary room, a cab, an electric room, a main transformer room, an engine room, a power room, a cooling room, a bearing type fuel tank, bogies and a frame. The upper body is composed of the auxiliary room, the cab, the electric room, the main transformer room, the engine room, the power room and the cooling room; the lower body is composed of the bearing type fuel tank and the bogies; the auxiliary room is arranged at the rear end of the cab, the electric room, the main transformer room and the main engine room are arranged at the front end of the cab, and the power room is arranged between the main engine room and the cooling room; dividing walls are arranged between the rooms; the bogies are arranged on the two sides of the bearing type fuel tank; the frame is arranged between the upper body and the lower body. The high-power alternating-current transmission shunting diesel locomotive is compact and reasonable in structure, convenient and fast to assessable, reliable in connection, suitable for large or medium shunting yards, also suitable for various severe climatic environments, small in routine maintenance quantity and easy to use and popularize.

Description

Technical field [0001] The invention relates to the technical field of a diesel locomotive, in particular to a high-power AC drive shunting diesel locomotive. Background technique [0002] With the development of domestic railway transportation, in recent years, the models that have taken on the main line cargo train traction task have been continuously updated, especially the large number of main trunk lines and the large-scale use of high-power locomotives, the traction number has been continuously improved, and the network performance of each road has been improved. The problem of the mismatch of the traction capacity of the reduced locomotives in the regional marshalling station has become increasingly prominent. Moreover, most of the shunting locomotives in domestic marshalling yards are relatively old, mainly DF5 and DF7 series. The locomotives have weak towing capacity, high failure rate and low operating efficiency, which can no longer meet the increasingly busy operating...
