Definitions

  • motors F can be insulated for that low voltage to ground and of extremely robust construction. In case of damage to one of them, such damage being notified by a suitable signal or tell-tale device, an individual cut-out switch S allows of isolating it, and the service can continue with the others.
  • Each fan motor F is cooled by a supply of fresh air, taken in at the second sky-light 28 and drawn along by the fan itself the air passing down a duct within the ventilation channel and escaping through holes in the fan nose, as shown by the arrows in broken lines (in Fig. 3) while the air cooling the resistances circulates upwards past the fan and is driven along the ventilation channel outside the duct therein to escape beneath the cowling 25 as shown by the arrows in full lines.
  • Accessibility to the commutators of these motors F is provided from the side gangways of the locomotive, inspection doors for this purpose being shown by the arrow F; disman- The traction unit I is located between two wide lateral gangways from which it is separated by several doors 29 which allow of inspecting all the internal equipment, including the resistances. These latter are mounted preferably upon insulating supports offusiform section, described in the French patent application filed on June 24, 1946, for Easily Cleaned Supporting Insulators.
  • Each resistance box can be withdrawn horizontally after dismantling the few connectors which lead thereto.
  • the unit l which contains all the electrical gear relating to the traction and to its auxiliary circuits, can be withdrawn upwards in a single piece after simply unwiring the connectors leading to the pantographs and to ground, the cables leading to the motors and the high-tension auxiliaries, and after the separation of a few couplings for the auxiliary circuits; if desired, the resistances can remain in place.
  • the traction unit can be broken up into several parts which can be forwarded to the various repair or maintenance shops; it is possible, for example, to subdivide it into three parts comprising respectively the fans, the resistances and the remainder which constitutes the traction equipment proper.
  • the end boxes 5 can with advantage be placed at the end of the traction unit 5, in front of the fan and compressor groups 2 and 3.
  • the ventilation of the two central traction motors can be furnished for example by two helicoidal fans with vertical shafts, enclosed in the unit I in the manner of the fans 2?, which allows again of installing the unit l in the very .center of the locomotive.
  • lay-out described allows of placing the parts such as the contactors, relays, controllers, etc., at the most suitable height for their inspection and examination; that the length of all the connectors and cables is reduced to the minimum, and that, in particular, the relative disposition of the contactors and resistances allows the use of straight and practically parallel connectors 23, shown in Fig.3 in the form of tubes or bars, which may be left bare, fixed on the front side of the equip- .ment behind the inspection doors 28 (Fig. 1).
  • the fans 2'! for the resistances can blow downwards fresh air drawn in through the cowling or sky-light, and in this case the special air inlet 28 for the cooling of the fan motors can evidently be suppressed.
  • the overhead cowling is suppressed and the cooling air is drawn into the locomotive body through suitably provided louvers til at the sides, the air passing over the lateral cabinets enclosing the groups M, Iii and i8, and escaping through the outlet grating under the ventilated compartment, as shown in the diagram of Fig. 4.
  • an electric locomotive of the type having a plurality of traction motors, a central chest provided with doors, two lateral unventilated cabinets for traction control apparatus and a ventilated compartment for air-cooled resistances, means for improving the general lay-out, increasing the efficiency of the cooling system. and corn trolling automatically the forced air-flow through said compartment, comprising an upright ventilation channel located between said lateral cabinets and containing a plurality of individually driven fans, motors for driving said fans being connected in parallel and inserted into a ground connection of said traction motors whereby said fan-driving motors are controlled by'the main current of the traction motors at starting the locomotive.
  • means for controlling economically without auxiliary apparatus the forced air-flow produced aoa'agoaciby said fans comprising the connection of" said fan-motorsbetween said traction" motors and ground, said fan-motors carrying the mainstarting current. ofat least one of said traction motors, whereby said: fan-motors are automatically controlled. at avery low voltage to ground, and being accordingly insulated for such very low volt age: 7
  • an electric locomotive means for automatically controlling theforced ,ir-fiow produced. by said fans, according to which said fen-motors are connected in parallel to form a group inserted: between at least one of said traction motors and ground inorderto-oarry the starting current of the locomotive, a contactor provided for the l'ast's'tartin-g notclibeaing connected across said group, whereby the fan motors are equivalent to alast section of starting resistance for said traction motor.
  • an electric locomotive or the type having a plurality of traction motors having a plurality of traction motors, a central chest provided with doors, two lateral unventilated cabinets for traction control apparatus and a ventilated compartment for air-cooled resistances, means for improving the general lay-out, increasing the eilicienc of the cooling system and con trolling automatically the forced air-flow through said compartment, comprising an upright ventilation channel located between said lateral cabinets and containing a plurality of individually driven fans, motors for driving said fans being inserted into a ground connection of said traction motors, an air-inlet grating under said ventilated compartment, an air-outlet cowling at the upper end of said ventilation channel, and shutters in said cowling.
  • an electric locomotive of the type having a plurality of traction motors, a central chest provided with doors, two lateral unventilated cabinets for traction control apparatus and a ventilated compartment for air-cooled resistances, means for improving the general lay-out, increasing the efiiciency of the cooling system and controlling automatically the forced air-flow through said compartment, comprising an upright ventilation channel located between said lateral cabinets and containing a plurality of individually driven fans, motors for driving said fans being inserted into a ground connection of said traction motors, the traction control elements enclosed in said chest being arranged and superposed in such order that they are all interconnected by short detachable leads having the form of practically parallel conductors fixed on the front of the equipment behind said doors in easily accessible positions with said doors opened.
  • an electric locomotive of the type having a central chest for the electrical traction equipment comprising motor control resistances, fans for cooling said resistances, groups of camoperated contactors co-operating with said resistances, and individual auxiliary control motors for operating said groups of contactors
  • an arrangement of said chest according to which all said traction equipment with the exception of: said auxiliary control motors is housed inside of said chest, which comprises in its upper part two unventilated lateral cabinets for said groups of contactors, a space for said fans intermediate between said cabinets, and interconnected with said intermediate space a ventilated compartment in the lowest part of said chest for said resistances, said auxiliary control motors being located outside of said central chest and rotatable manually' for emergency hand control of said groups of contactors.
