The invention discloses a train, a train power supply system and a leakage detecting and positioning device and method thereof, wherein the train power supply system comprises a plurality of power receiving units and a power grid for supplying power; each power receiving unit comprises at least one load and a first switch component for controlling power supply; the leakage detecting and positioning device comprises a plurality of leakage protection components, a plurality of first insulation detecting components, a plurality of controllers and a whole vehicle controller, wherein the pluralityof leakage protection components are used for detecting whether the train has high voltage leakage of a power grid; the plurality of first insulation detecting components are used for detecting load insulation resistance of the power receiving units; the plurality of controllers are used for controlling all the power receiving units to be disconnected with the power grid when at least two first switch components are disconnected and controlling the first insulation detecting component to work so as to judge the load leakage situation of the power receiving unit; the whole vehicle controller isused for positioning the power receiving unit on which the load leakage occurs. Thereby, orientation control on the power receiving units on which load leakage occurs / does not occur is facilitated so as to ensure the safety and reliability of operation of the train.
Description
technical field [0001] The invention relates to the technical field of train power supply, in particular to a leakage detection and positioning device for a train power supply system, a train power supply system, a train and a leakage detection and positioning method for a train power supply system. Background technique [0002] With the development of science and technology, my country's railways have entered the era of high-speed passenger transport, and trains have provided great convenience for people's travel. At present, the train is mainly powered by the grid, and mainly uses the DC trunk line power supply method. Once there is a fault on the train side when the power grid is powered, such as a leakage fault, it will directly affect the power supply of the train, and may also cause the train to fail to run. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain e...
