Abstract

The invention discloses a self-power-supply device and method for a wagon. The device comprises a transmission unit, a direct-current electricity generation unit, an energy storage unit, a control unit and a voltage conversion unit. The transmission unit transmits mechanical energy coming from an axle to the direct-current electricity generation unit. The direct-current electricity generation unit converts the mechanical energy transmitted by the transmission unit into alternating-current electric energy, converts the alternating-current electric energy into direct-current electric energy, and outputs the direct-current electric energy to the energy storage unit. The energy storage unit is controlled by the control unit to conduct charging or stop charging, and outputs direct-current voltage to the voltage conversion unit. The control unit conducts charging control on the energy storage unit according to the direct-current voltage output by the energy storage unit. The voltage conversion unit converts the direct-current voltage output by the energy storage unit into direct-current voltage required for the control unit and an electronic device of the wagon. The self-power-supply device is simple in structure, high in adaptability, good in electrical performance, high in reliability, convenient to maintain and capable of converting energy of the axle of the wagon into electric energy and storing the electric energy so that the power supply requirement of the vehicle-mounted electronic device can be met.

Description

technical field [0001] The invention relates to the field of electrical equipment for railway locomotives, in particular to a self-power supply device and method applied to railway freight cars, which are used to solve the power supply requirements of electronic monitoring and protection for freight car automation and intelligence. Background technique [0002] The railway is an important national infrastructure, the main artery of the national economy, and the backbone of the transportation system. It has the advantages of large transportation volume, low cost, energy saving and environmental protection. In recent years, with the rapid development of my country's economy, the railway transportation industry has achieved remarkable results. In terms of passenger transportation, high-speed railways and EMUs have made great leaps in development, especially EMUs. Since each car has a power supply system as a power source, on-board equipment such as electronic monitoring and pro...
