Abstract

The invention discloses a subway train voltage fluctuation prevention device. The voltage fluctuation prevention device comprises a voltage transformer 1, a voltage detection module 2, a memristor control module 3, a memristor driving module 4 and a memristor Rm. When the voltage of the pantograph passes through the main transformer, the input voltage is changed, the voltage transformer 1 convertsa voltage signal into a numerical signal through the voltage detection module 2 and sends the numerical signal to the memristor control module 3, and the memristor control module 3 changes the memristor value of the memristor Rm through the memristor driving module 4, so that the stability of the input voltage is realized. The subway train voltage fluctuation prevention device provided can effectively solve the problem of voltage fluctuation existing in contact network power supply, improve the running stability of the subway train and improve the riding comfort of a subway.

Description

Technical field [0001] The invention relates to an anti-voltage fluctuation device for subway trains. Background technique [0002] At present, the domestic subway power supply system uses the pantograph to introduce the high voltage electricity on the contact network into the traction motor. When the subway train is running at high speed, contact with power supply will cause voltage fluctuations; in addition, the electronic equipment on the subway train will also affect the voltage stability; the voltage fluctuation problem will not only reduce the service life of the subway train, but also affect the passengers taking the subway. Comfort. Summary of the invention [0003] According to the problems existing in the technical background, the present invention discloses a subway train anti-voltage fluctuation device, and the technical solution is as follows: [0004] A subway train anti-voltage fluctuation device is connected between the output terminal D1 of the main transformer an...
