Abstract

The invention discloses a filter performance testing device and method, and the device comprises a dusting box assembly which is internally provided with dust and is used for providing a dust environment; the dust collection channel is communicated with the dusting box assembly; the dust collection box is arranged at the bottom end of the dust collection channel and communicates with the dust collection channel; the ventilation channel is communicated with the dust collection channel; the filter is arranged between the dust collection channel and the ventilation channel; a draught fan is arranged in the draught fan containing cavity, and the draught fan containing cavity communicates with the ventilation channel. The technical problem that the filtering efficiency of the filter cannot be accurately tested in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a filter performance testing device and a testing method. Background technique [0002] As an important means of transportation in urban rail transit, subway has been paid more and more attention. At the same time, the requirements for traction equipment in subway vehicles are gradually increasing. However, as an important part of traction equipment, the converter is generally installed at the bottom of the car body. However, due to the large power dissipation of the power module and the large heat generated by inductive devices, the converter often uses forced air cooling to dissipate heat. [0003] In the prior art, in order to prevent sundries from entering the inverter, a dust and sand-proof filter is installed at the air inlet to separate large particles of dust, leaves, catkins, etc. in the air, so that cleaner air enters the inverter. The device dissipates ...
