Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] In order to realize the safe operation of EMUs with a speed of 350 kilometers per hour, according to the technical specifications for the traction transformers of the 350 kilometers per hour Chinese standard EMUs, and aiming at the common faults of the cooling units of the traction transformers of the existing EMUs, an innovative design of the traction transformer cooling unit was carried out.

[0035] A cooling unit for traction transformers (such as figure 1 As shown), including protective base assembly 1, vertical load-bearing column assembly 2, top load-bearing installation frame assembly 3, filter assembly 4, radiator assembly 5, fan duct assembly 6, fan unit assembly 7, electrical connector or junction box Assembly 8, radiator inlet and outlet butterfly valve 9 and other components:

[0036]The top load-bearing installation frame assembly 3 is provided with tw...

Abstract

The invention discloses a cooling unit for traction transformers of motor train units. The cooling unit has the advantages that matching technologies are optimized, so that fans of a cooling air system can assuredly work in high-efficient working areas, the heat exchange capacity, auxiliary power consumption and noise can be optimally matched with one another, the cooling unit is applicable to the motor train units with the speeds per hour of 300-350 kilometers, and requirements on the heat dissipation performance of the cooling unit can be met without increasing the weight of the cooling unit under the conditions of 380V and 50Hz or 440V and 60Hz three-phase alternating currents; the structural strength of the cooling unit can be reinforced by the aid of safety measures, and bottom plates can be prevented from falling off; the noise of the cooling unit can be lowered by the aid of comprehensive noise reduction measures.

Description

technical field [0001] The invention relates to the technical field of cooling systems for train sets. Background technique [0002] At present, the cooling unit of the traction transformer of electric multiple units in my country has the following shortcomings: [0003] (1) The FSA filter used in the cooling unit filter has high air resistance under the same flow rate, and the filtering effect is not good. That is to say, it needs to consume higher auxiliary power under the same cooling capacity, that is, high energy consumption. In addition, in spring and autumn, catkins and leaves often block the air intake channel of the air filter, and the filter needs to be cleaned frequently. It is difficult to disassemble and assemble the filter of the existing cooling unit, which brings great inconvenience to users. [0004] (2) The protective bottom plate of the cooling unit is directly used as the bottom plate of the equipment cabin under the EMU, and the conventional bolt conne...
