Problems solved by technology

[0003] Rail transit vehicle cooling towers are generally only equipped with a single fan and a single water pump, and the risk of rail vehicle machine breakdown due to failure of cooling tower components is extremely high
[0004] In the prior art, the traction transformer, traction converter, and train power supply cabinet cooling system are integrated in the same cooling tower, which simultaneously meets the heat dissipation requirements of the traction transformer, traction converter, and train power supply cabinet, but only involves the redundancy of fans Design, does not include redundant design of other components, such as water pumps, liquid level sensors, etc., and the integration level is not high, there are problems of high energy consumption and loud noise

Abstract

The invention discloses a redundant cooling tower for rail transit vehicles, which belongs to the technical field of rail transit and comprises an air cooling system, a converter water cooling system and a transformer oil cooling system. The air cooling system comprises a bottom mounting base, a heat exchanger, a multifunctional cabinet body, a main air cooler and a top air inlet duct which are sequentially arranged from bottom to top. The redundant design scheme of double fans, double water pumps, double liquid level sensors and the like is adopted, and the risk that a railway vehicle breaks down and stops running due to faults of the cooling tower can be reduced. On one hand, the risk that the motor train unit is damaged due to water pump faults is reduced, and even if one water pump breaks down, full-speed operation of the motor train unit can be guaranteed; and on the other hand, the service life of the water pumps can be greatly prolonged and the maintenance cost of the cooling tower can be reduced due to the alternate operation mode of the two water pumps.

Description

technical field [0001] The invention belongs to the technical field of rail transit, in particular to a redundant cooling tower for rail transit vehicles. Background technique [0002] A redundant cooling tower for rail transit vehicles belongs to an oil-water composite cooling tower, which is used for cooling traction converters and traction transformers of rail transit vehicles. The heat generated by the traction transformer and traction converter is brought into the heat exchanger of the cooling tower by the action of the oil pump and the water pump respectively, and dissipated into the atmosphere by the forced wind provided by the fan. Cooling towers are key functional components to ensure the reliable operation of rail vehicles. [0003] Rail transit vehicle cooling towers are generally only equipped with a single fan and a single water pump. The risk of rail vehicle machine breakdown due to failure of cooling tower components is extremely high. [0004] In the prior ...
