Simultaneously to the connecting line of additional fuel tank, the conspicuous relay (Buchholz relay) of cloth can be installed, make when the following 3 kinds of faults of the inner appearance of voltage transformer at voltage transformer:
1, gas is arranged in transformer oil.
2, because seepages etc. cause the voltage transformer leakage of oil.
3, because accident causes transformer oil to normal the flowing of additional fuel tank poor direction.
When above-mentioned fault occurring, the conspicuous relay of cloth can produce signal feedback at once, reports to the police or main circuit breaker of railway engine is disconnected, with the protection locomotive traction system.
The utility model H Exch adopts plate fin type radiator, and the upper strata is a water radiator, and lower floor is an oil radiator, and oil reservoir and water layer are distinct, and an air buffer is arranged between oil reservoir and the water layer, in case some loops have when leakage to influence another loop.The fin of air side is a single-piece, has connected oil radiator and water radiator, can not produce the space that accumulates dust with foreign matter, to prevent obstruction.
The top strip of paper used for sealing of the utility model H Exch adopts a kind of particular design, general radiator inner space liquid level is a level, exhausr port can not be arranged in the vertex of liquid level, particularly install not at ordinary times, when injecting liquid, can not be emptied completely internal gas, can only adopt the vacuum fluid injection could get rid of inner air fully, this programme is when design, last plane is provided with certain degree of dip, guarantee the vertex of point of release, do not need to carry out the vacuum fluid injection and can get rid of the fluid loop inner air fully at whole liquid level.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a lateral plan of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the compound cooling tower of the utility model profit divides oil piping system, water circuit system and air path system three parts, the compound cooling tower of whole profit is fixed on by on base 6 and the cabinet 17, and oil piping system, water circuit system and air path system three partial common Hs Exch 7, the upper strata of this H Exch 7 is water radiators, lower floor is an oil radiator, and be provided with an air buffer between the upper and lower layer, in case a certain loop has when leakage to influence another loop, also be provided with the air channel in water radiator and the oil radiator, this ducting system exit end leads to locomotive bottom atmosphere.
Oil piping system divides major loop and subloop two parts, and this major loop comprises by high temperature oil inlet flange 8 and cooled discharge flange 10, links to each other with locomotive main transformer by pipeline; This subloop comprises by pipeline 3, the conspicuous relay 4 of cloth, pipeline 5 and being communicated with voltage transformer that these pipeline 5 other ends are communicated with additional fuel tank 17, and this additional fuel tank 17 is connected with dryer 2 by pipeline 15, and an end of this dryer 2 directly is communicated with atmosphere.In the time of in working order, the major loop working condition is: high temperature oil is passed through oil pump from the locomotive transformer exit end, enter the oil radiator of H Exch 7 from high temperature oil inlet flange 8, high temperature oil is cooled off by H Exch 7, sends voltage transformer again back to by discharge flange 10 again.The subloop working condition is: because of the rolling stock operating ambient temperature changes (40 ℃～+ 70 ℃) greatly, the oil temperature changes bigger, cause the volume change of oil bigger, when oil volume increases in H Exch 7 and the voltage transformer system, the part oil that increases, is stored in the additional fuel tank 17 by pipeline 3, the conspicuous relay 4 of cloth, pipeline 5 from voltage transformer; When oil volume reduced in H Exch 7 and the voltage transformer system, the oil in additional fuel tank 17 entered voltage transformer by pipeline 5, the conspicuous relay 4 of cloth, pipeline 3, with the oil mass of makeup oil circulation loop.For guaranteeing the equilibrium of pressure in circulation of the oil loop, a dryer 2 is housed is connected with additional fuel tank 17, dryer 2 directly is communicated with atmosphere simultaneously, when the volume change of circulation of the oil loop, air enters additional fuel tank 17 tops by dryer 2, makes the pressure in the additional fuel tank 17 keep balance.
Water circuit system also divides major loop and subloop two parts, this major loop comprises high-temperature water entrance pipe 14, the water radiator of the H Exch 13 that is communicated with current transformer, the other end of this water radiator is communicated with water pump 16 by pipeline 11, and the export pipeline 9 of this water pump 16 is communicated with main convertor; This subloop comprises pipeline 1, expansion tank 13, pipeline 12, and an end of this expansion tank 13 is communicated with water pump 16 by pump entrance pipeline 12.During use, the major loop working condition is: main convertor high-temperature water cooling agent enters the water radiator of H Exch 7 from entrance pipe 14, high-temperature water cooling agent is cooled off through the water radiator of over-heat-exchanger 7, by water pump 16, sends current transformer again back to through export pipeline 9; The subloop working condition is: generally speaking, part water coolant enters expansion tank 13 from the current transformer exit end by pipeline 1, enter major loop by pipeline 12 again, when bigger variation takes place in ambient temperature, coolant volume expands when increasing in H Exch and the current transformer, part water coolant 1 directly enters expansion tank 13 by the road from the main convertor exit end, enter major loop by pipeline 12 again, the a part of water coolant that increases is stored in the expansion tank 20, when coolant volume reduces in H Exch and the current transformer, reduce the part water coolant and add to the major loop from expansion tank 13 outflows.These expansion tank 13 designs have its uniqueness, and open in the patent CN2008100314431 of the previous application of applicant, it is called the expansion tank of locomotive with anti-cavitation erosion).
