Title:
RAIL VEHICLE AUXILIARY CONVERTER SYSTEM AND RAIL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/045282
Kind Code:
A1
Abstract:
Disclosed are a rail vehicle auxiliary converter system and a rail vehicle. The auxiliary converter system comprises a housing (100), an air supply fan (300) and an auxiliary converter. The housing is provided with an air inlet (101) and an air outlet (102), wherein the air inlet is connected to the air supply fan. A left partition plate (103) and a right partition plate (103) which are perpendicularly connected to a rear plate of the housing are provided in the housing. The left partition plate is parallel to the right partition plate. The auxiliary converter comprises a power unit (201), a transformer (203), an alternating current reactor (204) and a direct current reactor (205). The power unit is fixed between the left partition plate and the right partition plate, and a heat dissipation module (202) is fixed to the top part of the power unit. The transformer is fixed on a right side of the right partition plate, the alternating current reactor is fixed on a right side of the transformer, and the direct current reactor is fixed above the alternating current reactor. Since an air cooling method of providing an air inlet and an air outlet on the housing and transmitting air into the housing via the air supply fan, there is no need to arrange a complex cooling pipeline in the auxiliary converter so that the auxiliary converter is simple in system structure and is convenient to mount, and the mounting and maintaining costs are reduced.
