Problems solved by technology

[0003] The traditional auxiliary power system is generally a power frequency inverter circuit topology, which adopts forced air cooling or natural cooling. The auxiliary inverter and charger are separated, resulting in a large system size and poor heat dissipation. And the traditional auxiliary power system has been difficult to reduce the weight in essence

Abstract

The invention discloses a power module of an auxiliary power system. The power module comprises a frame assembly for mounting electrical components, and a water-cooled plate assembly for cooling and heat dissipation, an auxiliary inverter power unit device, and a charger power unit device which are detachably mounted in the frame assembly; the water-cooled plate assembly comprises a water-cooled substrate; the auxiliary inverter power unit device comprises an auxiliary inverter power unit; the charger power unit device comprises a charger power unit; and the auxiliary inverter power unit and the charger power unit are mounted at the two sides of the water-cooled substrate, so that the water-cooled substrate can take away the heat generated by the auxiliary inverter power unit and the charger power unit in time. Accoridng to the power module of the auxiliary power system provided by the invention, the heat dissipation capability is strong, and the lightweight design of the auxiliary power system can be well realized.

Description

Technical field [0001] The invention belongs to the technical field of rail vehicles, and particularly relates to an auxiliary power supply system of a rail vehicle. Background technique [0002] The auxiliary power system of urban rail vehicles generally includes auxiliary inverters and chargers. At present, the auxiliary power systems for urban rail subways are mostly industrial frequency auxiliary inverters + high-frequency chargers, and their application methods are generally divided into two types: One is that the auxiliary power system is integrated in a box, which is divided into auxiliary inverter power modules and charger power modules, and the other is that the auxiliary power system is distributed and divided into auxiliary inverter boxes and charging cases. This traditional auxiliary power system needs to use a power frequency transformer, resulting in a large volume and weight, and it is difficult to achieve the purpose of miniaturization and lightweight design. Wit...
