Background technology
The main transformer of modern electric locomotive generally is to adopt dedicated transformer oil to cool off, and transformer oil is a dielectric, also is coolant.Variations in temperature before and after the transformer oil work generally can reach 60K (rising to 85 ℃ from 25 ℃), the north and highlands, and temperature rise is bigger, is affected by thermal expansion and contraction, and bigger variation can take place in the volume of transformer oil.
For buffering being provided to transformer oil; Guarantee the pressure stability of circulation circuit, locomotive is all wanted oily expansion tank of serial or parallel connection, and tandem oil expansion tank needs to hold whole transformer oil; Volume is very big; Uneconomical, parallel oily expansion tank only needs to hold the change in volume of expanding with heat and contract with cold and producing, and volume is less.What at present domestic and international AC electric locomotive transformer generally used is the oily expansion tank of parallel biasing, merges into a single whole with the cooling tower frame, and oily expansion tank is welded on a side of locomotive cooling tower frame, and blower fan is in outside the oily expansion tank.
Domestic and international oily expansion tank has more following problems at present: one, cause cooling tower frame centre-of gravity shift, loading and unloading are inconvenient.Two, the cooling tower space availability ratio is limited, and when the electric locomotive transformer capacity strengthened, surge volume was not enough.Three, receive structural limitations, oily expansion tank rigidity is not too high, and sealing detection pressure is too big, otherwise causes moderate finite deformation, so poor sealing performance, leakage of oil is serious, even the generation machine is broken, causes Shanghai Communications University potential safety hazard and economic loss to locomotive.Four, the unsettled oily expansion tank outside that is installed in of former cooling blower, air inlet need adopt special-purpose hermetically-sealed construction and encapsulant, and is high to the parts required precision, and cost is high.
Summary of the invention
The purpose of the utility model is to the problems referred to above; Under the prerequisite that guarantees the transformer oil surge volume, a kind of compact conformation is provided, in light weight, low cost of manufacture; Easy to maintenance, the locomotive that the while rigidity of structure is greatly improved is with square-outside and round-inside chamber transformer oil expansion tank.
The technical scheme of the utility model is: a kind of locomotive comprises transformer, oil pump, metal hose, radiator, buffering oil pipe, oily expansion tank and blower fan with square-outside and round-inside chamber transformer oil expansion tank, it is characterized in that:
Described oily expansion tank is the square-outside and round-inside chamber structure; Be that oily expansion tank is welded into an airtight ring cavity container and is constituted oily expansion tank main body by left plate, top board, inner core, right panel, base plate, header board, be welded with four groups of fan supporters that are used to connect blower fan, a quadruplet lifting nut and a cover oil level display tube that is used to load and unload whole cooling tower in this oil expansion tank;
The left plate upper end of described oily expansion tank is provided with a pneumostome, is communicated with through the buffering oil pipe between oily expansion tank and the transformer, promptly cushions oil pipe one end and links to each other with base plate below the oily expansion tank, and the other end is connected with the transformer top board;
The header board below of described oily expansion tank is provided with the luffer boards of safeguarding that are used to be convenient to the radiator of oily expansion tank below is cleaned upkeep operation;
Described blower fan is arranged on four groups of fan supporters in the oily expansion tank, and the mounting flange of its blower fan and the top board of oily expansion tank are tightly connected, and the chimney fan of blower fan is installed in the middle circular cavity (inner core) of oily expansion tank.
The innovative point of the utility model is: the oily expansion tank that will be arranged in the single side of locomotive cooling tower frame originally expands to whole cooling tower upper rack branch; Oil expansion tank structure is changed into the square-outside and round-inside structure of traverse by original vertical rectangular cabinet; Originally be distributed in the outside fan supporter of oily expansion tank, and changed seal weld into and be connected on oily expansion tank inner held concurrently longitudinal bracing and the laterally effect of reinforcement; The cooling blower mounting means changes flange face into and directly is connected with oily expansion tank top board plane, has saved the seal member of air inlet, has reduced the accuracy of manufacture requirement of link.
The utility model has increased oily expansion tank volume, has reduced the cooling tower overall dimensions, has improved the Operation and Maintenance performance of locomotive cooling tower, has practiced thrift human resources in a large number, has obvious social; Oil expansion tank structure distribution is even, and center of gravity is reasonable, is convenient to loading and unloading; The rigidity of structure improves, and can increase sealing detection pressure, improves sealing property; Improve the blower fan mounting means, reduced the manufacturing cost of the seal request and the associated components of air inlet, had tangible economic benefit.
