Description
Electric locomotive main transformer of the present utility model belongs to the heat transfer technology field with novel oil cooler, and oil cooler is used to cool off main transformer work oil, with the operate as normal of protection main transformer.
In prior art, electric locomotive main transformer uses oil cooler shown in accompanying drawing 1,2,3,4,5.It is by passing in and out oil pipe (3,1), cooling fuse (10), turnover oil duct (5,4), oil exit pipe (6), oil back chamber (11), outer cover (16) and going up lower support plate (13,12) composition, and its cooling fuse (10) is a rectangle.The work oil of main transformer heat is extracted out from fuel tank, enter oil inlet pipe (3),, come together in oil back chamber (11) after the cooling through oil input channel (5), cooling fuse (10), oil exit pipe through being positioned at the cooler both sides (6) respectively then is to oil road (4), flowline (1), return oil tank of transformer.The heat of work oil is loose through wind side fin (7) and is cooled off in atmosphere by oily side fin (8), dividing plate (9) in the cooling fuse (10), and there are many problems in the oil cooler of this structure in practice.
1. be positioned at the oil exit pipe (6) of oil cooler both sides, every side is made up of 8 aluminum pipes that reach 1 meter respectively, has 32 attachment welds between they and oil road (4), oil back chamber (11), often because of the weldquality problem produces leakage of oil, causes locomotive failure in the utilization;
2. the top board (2) of oil road (4) produces distortion (as shown in Figure 3 because of the oil pressure effect of pulsation, A: be the normal condition of top board (2) before the oil pressure effect of oil road (4), B: be top board (2) deformation state after the oil pressure effect of oil road (4)), for preventing distortion, need install bracing means (18) additional, make the cooler construction complexity, weight increases;
3. because cooling fuse (10) adopts rectangle structure, each cool off fuse (10) in the cooler shown in accompanying drawing (5).This layout makes the interior side seal bar (14) that respectively cools off fuse (10), and when snapping leakage of oil, device can't be repaired, and can only scrap.
The existence of these problems, make electric locomotive main transformer with oil cooler usually because of weld seam is many, yielding, and leakage of oil takes place, failure rate height, maintenance difficult influence traffic safety.
The purpose of the present utility model is: for the cooling of electric locomotive main transformer oil provides a kind of novel oil cooler, it is by changing the shape and the arrangement of cooling fuse, change the structure and the layout of turnover oil duct, oil pocket, reach the mechanism that reduces weld seam, reduces the leakage of oil generation, improve the cooling fuse oil-feed uniformity, thereby the reduction failure rate, convenient for maintaining guarantees that application safety is reliable.
The novel oil cooler of electric locomotive main transformer of the present utility model, it is made up of turnover oil pipe, turnover oil duct, turnover oil pocket, cooling fuse and last lower support plate.Its cooling fuse is short flat, and each cools off between fuse for being arranged in juxtaposition; Turnover oil duct and turnover oil pocket form by the garden arc aluminium sheet cover and the garden arc aluminium sheet assembly welding of band supporting rib; The turnover oil pocket places the both sides of cooling fuse end respectively, and is welded on the cooling fuse skirt section; The turnover oil duct will pass in and out oil pipe and the turnover oil pocket couples together, and is welded on the side guard plate of cooling fuse by the oil duct base plate; On the intermediate support muscle of turnover oil duct and turnover oil pocket, have a lot of oilholes; Between oil suction chamber and cooling fuse, be welded with flow distribution plate; Flow distribution plate is an isosceles trapezoid; Be welded with the taper sheath in turnover oil pipe and turnover oil duct junction.
Electric locomotive main transformer of the present utility model has creatively carried out the improvement of structure and layout with novel oil cooler, thereby can obtain good actual effect.
1. because after turnover oil duct and turnover oil pocket adopt the garden arc aluminium sheet cover and garden arc aluminium sheet assembly welding of a band intermediate support muscle, side guard plate and skirt section with the cooling fuse is welded into one respectively, thereby form a closing force flow structure, the rigidity and the intensity of oil duct and oil pocket have been strengthened widely, help bearing the pulse oil pressure, replace 16 oil exit pipes and 32 attachment welds in the prior art, reduced the possibility of snapping leakage of oil; Overcome the shortcoming of oil input channel roof deformation in the prior art again, improved the cooler serviceability greatly;
2. because the cooling fuse adopts short flat, make and respectively cool off fuse in the cooler and can be arranged in juxtaposition, the weld seam that so respectively cools off oil sealing bar between fuse all is positioned at the surface of cooler.In case when snapping leakage of oil, very easily find and repair easily.
3. between oil suction chamber and cooling fuse, be welded with the flow distribution plate of isosceles trapezoid, can improve the oil-feed uniformity, thereby improve cooling capacity.
4. add weldering taper sheath in turnover oil pipe and turnover oil duct junction and can strengthen bonding strength between them, overcome the influence that the locomotive operation vibration brings.
The novel oil cooler of electric locomotive main transformer of the present utility model in a word, than prior art have simple in structure, weld seam is few, structural strength and rigidity improve greatly, cooling effect is good, thereby effectively raise oil cooler serviceability and durability, convenient for maintaining again, be suitable for practicality, have good economic benefits and social benefit.
