Embodiment 1

[0032] figure 1 It is a schematic structural diagram of the auxiliary converter system of a rail vehicle, such as figure 1 shown.

[0033] One aspect of the present invention provides an auxiliary converter system for a rail vehicle, including: a housing 100 , a blower fan 300 and an auxiliary converter. Wherein, the housing 100 includes a top panel, a bottom panel, a left side panel, a right side panel, a front panel (not shown) and a rear panel. An air inlet 101 and an air outlet 102 are opened on the casing 100 , and the air inlet 101 is also connected with a blower fan 300 . Meanwhile, the left partition 103 and the right partition 104 are vertically connected on the rear panel of the housing 100, and the left partition 103 is parallel to the left side panel, and the right partition 104 is parallel to the right side panel. The auxiliary converter includes a power unit 201, a transformer 203, an AC reactor 204, and a DC reactor 205; wherein, the power unit 201 is fixed b...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 is that: the auxiliary converter system of this embodiment is provided with an air volume regulating device 400 inside the casing 100, such as figure 2 as shown ( figure 2 for figure 1 Schematic diagram of the rail vehicle auxiliary converter system after installing the air volume adjustment device). A local air channel is formed between the air volume adjusting device 400 and the casing 100 and the auxiliary converter to adjust the flow direction of the wind, or adjust the flow rate of the wind, or adjust both the flow direction and the flow rate of the wind at the same time.

[0042] By setting the air volume adjustment device 400 in the auxiliary converter system, a local air duct can be formed, which is beneficial to provide appropriate air volume for different electronic components of the auxiliary converter to obtain the best cooling effect, thereby improving the operation of the auxiliary converter effic...

Embodiment 3

[0051] Another aspect of the present invention also provides a rail vehicle, on which the above-mentioned auxiliary converter system is installed.

[0052] The auxiliary converter system and the rail vehicle provided by the present invention are provided with an air inlet 101 and an air outlet 102 on the housing 100 of the auxiliary converter system, and the fan 300 is used to deliver a large amount of air to the housing 100. The cooling method does not need to arrange complex cooling pipes in the auxiliary converter, which not only simplifies the structure of the auxiliary converter system, but also makes the installation of the auxiliary converter system easier and reduces the cost of installation and maintenance.

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.

Description

technical field [0001] The invention relates to a rail vehicle auxiliary converter system and a rail vehicle, and belongs to the technical field of rail vehicle equipment. Background technique [0002] In rail vehicles, an auxiliary converter system is generally set up to rectify the single-phase AC 340V output from the auxiliary winding of the main transformer of the vehicle, and then invert it into a three-phase AC 380V, thereby supplying power to various auxiliary equipment on the vehicle. The rail vehicle auxiliary converter system in the prior art includes a housing and an auxiliary converter fixed in the housing. The auxiliary converter includes several electronic components such as a power unit, a transformer, an AC reactor and a DC reactor, and these electronic components generate a large amount of heat during operation. Therefore, in order to ensure the normal operation of these electronic components, the auxiliary converter system is generally cooled. [0003] Th...
