Embodiment Construction

[0016] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0017] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0018] like figure 1 , The locomotive AC train power supply device of the present invention includes a control signal input terminal, which can be a "train power supply" switch on the driver's cab console, an AC auxiliary generator, a diesel engine, a microcomputer, a speed sensor, and a train power supply cabinet.

[0019] The diesel engine has a storage battery for ignition, and the diesel engine has a transmission connection with the AC au...

Abstract

The invention discloses a locomotive AC train power supply system and a power supply control method thereof, relates to the train power supply technology, and provides a locomotive AC train power supply system and a power supply control method thereof aiming at the defect in the prior art that the power energy demand is not ensured when a train breaks down. The technical points of the invention are that: a control signal input terminal, a microcomputer, a rotating speed sensor, and a train power supply cabinet are additionally installed based on an existing diesel engine, and an AV auxiliary generator for locomotive AC auxiliary transmission; the microcomputer is in signal connection with all of the control signal input terminal, the rotating speed sensor, the AV auxiliary generator, a diesel engine throttle control terminal, and the train power supply cabinet; the AV auxiliary generator supplies power to the train power supply cabinet, and a AC power supply output terminal of the train power supply cabinet is used to supply power to the train; the microcomputer adjusts the size of the output voltage of the AV auxiliary generator according to a rotating speed signal of the diesel engine outputted by the rotating speed sensor so as to ensure that the train power supply cabinet outputs stable 380 V three-phase AC power for the train.

Description

technical field [0001] The invention relates to train power supply technology, in particular to a locomotive AC train power supply device and a power supply control method thereof. Background technique [0002] At present, most of the AC / DC electric drive diesel locomotives produced in China (exported or used in China) do not have the train power supply function. Electricity demand is not guaranteed. [0003] Existing very few locomotives with train power supply function use auxiliary diesel engine to provide train power supply function, thus adding a diesel generator set, thus increasing many failure points, and greatly increasing the cost, and occupying a large amount of power on the locomotive precious space. Contents of the invention [0004] The purpose of the present invention is to design a locomotive AC train power supply device and its power supply control method on the basis of the existing locomotive AC auxiliary generator, so as to provide a locomotive AC tra...
