Description

technical field [0001] The invention relates to the technical field of electric locomotives, in particular to a wind speed detection device and method for a cooling system of a railway electric locomotive. Background technique [0002] With the development of science and technology, electric locomotives have been widely used in the field of railway transportation, and the speed of trains has also been greatly improved. However, as the speed of the electric locomotive increases, the locomotive traction motor of the electric locomotive will generate high temperature when the locomotive is running, which will affect the safe operation of the electric locomotive. Therefore, it is necessary to cool the locomotive traction motor of the electric locomotive. The traction motors of modern electric locomotives are usually cooled by ventilation, and the ventilation system adopts the ventilation mode of the car body, and the cooling of the traction motors of the locomotives is mainly ac...

Problems solved by technology

[0003] Although, in theory, directing the air outside the locomotive with a certain wind speed to the traction motor of the locomotive through the ventilation system can fully cool the traction motor of the locomotive and ensure the safe operation of the electric locomotive. The incoming air enters and reaches the traction motor through different components. The size and shape of each component are different, and the resistance generated is also different. Therefore, the flow rate and wind pressure of the cooling air that finally flows to the traction motor are different from the theoretical calculation. In this way, the traction motor will not get enough cooling air flow and wind pressure, which will eventually lead to excessive heat generation of the traction motor, which will affect the insulation performance of the traction motor, cause the traction motor to burn and cause machine damage, and cause major safety hazards to the operation of the locomotive.

In addition, if the flow and pressure of the cooling air are excessively increased, the design of the flow and pressure parameters of the cooling air may be too high, resulting in high production costs and unnecessary waste

In order to ensure safe driving and save energy, it is necessary to test and measure the air outlet of the locomotive cooling system. Manual operation, low efficiency, low reliability, difficult to control quality
