Embodiment
Fig. 1 is illustrated in trailer system such as subway or the underground system, is installed on the perspective view of the current transformer casing of underfloor.Current transformer casing 1 comprises comprising aftermentioned and is used to drive the current transformer of traction motor (not shown) of trailer system and the current transformer shell of auxiliary unit.
Current transformer casing 1 is rectangular shape basically and is formed in the support 2, the current transformer casing 1 of lid, plate and revolving door formation sealing disposed thereon.Concrete, current transformer casing 1 comprises loam cake 3, with the lower cover 4 of loam cake 3 parallel positioned opposite, and four side covers 5 that are orthogonal substantially and arrange with loam cake and lower cover 3,4.Each lid 3,4,5 can be made by a part or several sections.Upper and lower covers 3,4 preferably is made of metal, preferably has to avoid the surface treated of corroding, or other electric conducting material arbitrarily.Lid 3,4,5 is riveted on the support 2 usually to guarantee the suitable sealing with external environment condition.
Some lids 3,4,5 can have the internal module that allows to lead in the shell and other parts to be used to keep in repair the opening of purpose.These openings can be used plate, and such as plate shown in Figure 1 10, and/or the revolving door that is attached at current transformer casing 1 respective openings seals.Plate 10 can be such as being attached on the opening by screw.Be screwed the inside that can allow to enter shell by opening by dismounting plate 10.Screw is furnished with safety and press-fits bolt in order to avoid lose screw because vibration waits.In addition, although there is judder during operation, they have guaranteed minimum momentum.Plate 10 preferably at its edge or the place of keeping to the side with the sealing of rubber strip of paper used for sealing, to guarantee that current transformer inside seals fully with dust and water protection when mounting cover 3,4,5 and the plate.
Current transformer casing 1 should be installed under the vehicle floor.It is fixing to utilize four installing racks 6 to realize.Installing rack 6 is attached to the appropriate location so that do not damage the mechanical stability of current transformer casing 1.Preferably, installing rack 6 is arranged in the corner location of current transformer casing 1 loam cake 3 on the support 2.
Fig. 2 illustrates the more detailed view of the installing rack 6 that is used for Fig. 1 current transformer casing 1.Installing rack 6 is attached on the support 2 of current transformer casing 1 with screw by using a plurality of construction bolts 7.Each installing rack 6 can comprise can be at a plurality of welding portions of diverse location screw to the support 2.
As an example, construction bolt 7 is arranged on the support 2 of loam cake 3 one sides.The second portion 12 of installing rack 6 has the installed surface of the extension of the first 11 that is substantially perpendicular to installing rack 6.The connection surface of second portion 12 is attached on the surface perpendicular to the support 2 of loam cake 3.In addition, the backbar 8 that extends vertically up to lower cover 4 from the plane of loam cake 3 is set.The far-end of backbar 8 is installed on the support 2, particularly at the connection loam cake 3 of support 2 and the side of lower cover 4 (perpendicular to loam cake 3) on the part with fixing and mounting bracket 6.
Generally speaking, because installing rack 6 is not welded on the current transformer casing 1, but above screw arrives, so current transformer casing 1 can utilize different types of installing rack 6 to be installed on the vehicle of several types.
According to Fig. 1, shown in plate 10 cover opening on the first side cover 5a, one or more semi-conductor power modules can insert in the shell and therefrom by the opening on the first side cover 5a and remove.Used for semiconductor power module is in driving the traction motor that is connected with current transformer casing 1.They also can comprise the AuCT that is used to AC threephase load power supply and/or be used to the DC electric and be the battery charger of battery charge.By removing plate 10 and then unclamping the electrical connection of power model and mechanical connection and can take out semi-conductor power module with the assembling of cooling system.Can remove power model inside by being pulled outwardly power model now.
Fig. 3 and 4 illustrates the different views on second side cover 5 relative with first side cover 5.The second side cover 5b has the opening that heat exchanger 14 wherein is installed.Heat exchanger 14 is arranged on the revolving door 15 and comprises two fans 16.After revolving door 15 is opened, just can reach fan 16.In addition, along with revolving door 15 is opened, can and be positioned at other internal part of shell compartment.When opening under the situation that revolving door 15 can reach compartment, compartment comprises the parts of cooling system, such as pump 17, expansion tube 18 or the like.Revolving door has the inlet heat exchanger 19 (referring to Fig. 4) that allows air to flow into and is included in outlet grid 20 in the lower cover 4 (in this place's hot-air ejection).Because cooling system contacts the necessary cleaned at regular intervals of dust easily, revolving door 15 allows can reach cooling system fast.As can be seen from Figure 4, comprise the compartment of relay 21 and contactor 27 in addition on the second side cover 5b, described relay and contactor are covered by relay shown in Figure 3 and contactor cover plate 22.Cover plate 22 is fixed on the second side cover 5b by above-mentioned screw.
According to Fig. 5, the perspective view of the 3rd side cover 5c is shown.The 3rd side cover 5c comprises the opening that can be covered by plate, and this plate can use that to push bolt as safety attached by screw.Behind the plate in the respective compartment of shell control unit 23 is installed, control unit 23 comprises that be installed in can be towards the one or more circuit boards in the support 28 of pre-portion swing.Support 28 by side 24 and 25 protections of preceding screening glass.Have the other parts 26 that to remove under the trouble hunting situation after the control unit.
Power connection is arranged on the 3rd side cover 5c and the 4th relative side cover 5d shown in Figure 6.Have the input power cable that is connected with catenary on the 3rd side cover 5c, on the 4th side cover 5d, have the connector that is used for the output power cable that is connected with the auxiliary equipment (not shown) with traction electric machine.Connect the cable of input and output must screw to corresponding electric power terminal so that safe electrical connection is provided.Electric power terminal is positioned at after the plate with the cable clip that is used for each output power cable.For entering electric power terminal, the cover plate 32 among Fig. 6 must be unscrewed screw, so that it separates from current transformer casing 1.Therefore, before being installed to other parts of current transformer power cable can install by, be cut and be equipped with pot head.The advantage of this solution is can be ready to cabling fully and current transformer can be installed subsequently.
On the input power connection, safe measurement and grounding system are set.The input power connection is arranged in the compartment that is covered by plate 32.After open plate 32, (removed plate 32) as shown in Figure 6, have by insulating material the insulating trip of making such as plastics (can enter) from revolving door 31 with aperture.The hole is sized to these holes and does not allow by the part that insulating trip covers any contact is arranged, so that can avoid electric shock under the situation that still applies catenary voltage.But, allow the measuring probe patchhole to be hidden in insulating trip corresponding connectors afterwards to measure electric weight with contacting.Therefore, might check in current transformer casing 1 whether remaining any residual voltage that has safely.
The loam cake 3 of current transformer casing 1 is provided with another plate 30 (see figure 1)s that cover loam cake 3 openings.Under the situation of the trouble hunting of some other parts in the compartment that is arranged between power model and cooling system, removable plate 30.Because current transformer casing 1 is designed to be installed under the floor, loam cake 3 is relative with the floor of vehicle simultaneously, and this operation is only finished from the vehicle disconnection with after removing current transformer casing 1.According to this constructive solution, make assembling, installation and the trouble hunting current transformer that all do not need to overturn become possibility.
