Definitions
- composite section units are provided.
- The'present'invention relates to systems for electric power supply to a'device moving along'a track, for example an electricallypoweredcraneI
- the power supply to such devices is efi'ected through rails'mounted along the'tr'a'ck and a'corresponding nii'nilzie'r of current collectors with spring-loade'd'slide contacts are moiinted orithedevice.
- Each of the'conductor rails has an unins'ulated enera face affordingelectric contact with the collector'sliding along theraill I Sticlit'ra'cksmay'be very long,'-upto several hundred meters, and the contact'r'a'ils' are mostly divided into longitudinalsections, iisually about 7 to l'4meters longrAsfew joints as possible'a're desired,but on the other hand, for convenient handling the sections'ough't'not to be too long. Provision must be made for a ther'rnal'ex'pansion and contractionof the rails, and it is th'e'r'efo'r'euslial'tdprovide several expansion joints in'these.
- the present invention has for an object to overcome this drawback and primarily consists in providing a se-called comp'e'nsate'd conductor system for the individual contact rails by closely placing" along each contact rail additional phase conductors stibsta'ntially of largely equivalent cross section and in a number correspondingto the number. of the remaining phase contact rails andeach conductively connected to one of the remaining phase contact rails at pointsndistributed along the track.
- the system of the invention also provides a compositeconductor section adapted to be used such a plant, and characteriz'ed in that'it consists of a contact rail partly surrounded by insulation and one or more additional conductors of substantially' equivalent cross section and entirely surrounded by the insulation.
- FIG. 1 is a diagrammatic cross-sectional view of the conductor rail system with cross-connections added.
- FIG. 2 is a circuit diagram ofth'e system of the invention. As a consumer unit on'the movable device (the crane) only a motor M connected to the current collectors 15 to 17 has been indicated in the drawings.
- each rail unit comprises the three phases R, S and T of a three-phase system, but the phases are cyclically interchanged in the three rail units.
- the three conductors of each phase are interconnected by transverse connections designated by 10, 11 and 12 in FIG. 1.
- the insulation of each rail unit is composed of an insulating compound cast around it as indicated at l3, l4 and 15, respectively, in FIG. 1.
- the power supply plant according to the invention will result in an improved power factor as compared with previously known contact rail plants for the same purpose.
- the power supply system will comprise two contact rails, each with one conductor at a short distance from the rail and connected to the other phase of the system.
- the conductors of the same phase are interconnected by a number of cross-connections, likewise atintervals of about 7 to 14 meters.
- each contact rail there shall be placed one conductor for each of the remaining phases of the system, it will, of course, be understood that each such additional conductor may be composed of a plurality of parallel-connected conductor strands.
- a system comprising: a plurality of spaced electrically conductive contact rails for supplying power to the carriage; additional elongated conductors closely extending along and electrically insulated and associated with each of said contact rails in a number equal to the total number of contact rails less one, the additional conductors each having substantially the same electrical resistance per unit length as the contact rail; and connected means electrically connecting each of said additional conductors with one each of said contact rails other than with which said additional conductors are associated, so that current drawn by the electrically operated carriage through said collectors is shared substantially equally by each contact rail and said additional conductors which are electrically connected is bunched with its said associated additional elongated conductots in insulated relation.
