Description
Technical Field
The invention mainly relates to the field of rail transit equipment, in particular to a ventilation and filtration device for rail transit.
Background
With the development of society, rail transit vehicles have reached all around, and particularly, domestic rail railways are distributed in various places throughout the country. As is well known, when an electrical device is operated, a transformer, a reactor, and the like mounted in the product are heat generating devices, and the amount of generated heat is very large. The failure rate of the electrical product increases exponentially with the increase of the environmental temperature, and the service life decreases exponentially with the increase of the environmental temperature. Due to the limitation of installation space and the like, electromagnetic components such as transformers and reactors in the electrical equipment adopt a natural cooling design, and interact with air outside the cabinet through heat dissipation holes, so that the heat dissipation performance is improved. The following technical problems exist in the working process of the existing electrical equipment:
(one) the filtration performance is not good. Because the electrical equipment is arranged at the lower part of the train body and is directly contacted with the nature, the train is difficult to avoid the weather of wind, sand, rain and snow in the running process, and the locomotive running at high speed can inevitably drive dust particles around the train, so that the dust content of the surrounding air is increased. And can make the cabinet body be the negative pressure when the vehicle operation, this can make a large amount of dust or sleet inhale the cabinet internal portion from the louvre, and lead to the device to burn and lose, influence electrical equipment's normal operating for cost of maintenance is high, influences the safe operation of train even when serious.
(II) poor heat dissipation performance. Some products can only reduce the size and the quantity of louvre for realizing filtering, and this leads to the heat dissipation of electromagnetic component such as transformer, reactor among the electrical equipment not in time enough, the radiating effect is not good again, and equipment is overheated and leads to the device to burn and lose, influences electrical equipment's normal operating for cost of maintenance is high, influences the safe operation of train even when serious.
And (III) difficult maintenance. Because the maintenance time of the railway product in the normal operation is short, the product needs to be free of maintenance as much as possible, so that the dust filter device can be free of cleaning on the basis of ensuring the reliable protection effect. However, the existing product is not easy to maintain, needs to be cleaned regularly, and increases the maintenance cost. For example, in the prior art, when a vehicle runs in the northeast region in the winter snowy weather, rain, snow and sand enter the cabinet body through the louver holes, and the rain, snow and sand cannot be discharged out of the cabinet body from the bottom in time due to low local air temperature. If the device is not maintained in time, rain, snow and sand dust are gradually gathered in the device, and when the snow is melted into water, moist sand mud is formed, so that the insulating property of the device is reduced, and finally the device is burnt.
