Technology and Engineering. Electric Railways Theoretically and Practically Treated

Technology and Engineering. Electric Railways Theoretically and Practically Treated. Electric Railways Theoretically and Practically Treatedby Sydney W. Vol. Realizing the absence of a suitable text on Electric Railways, treating of the Engineering Preliminaries and direct-current sub-station Operation, it has been the purpose of the writer to prepare such a volume.

Starting by means of a small direct-connected induction motor. C. Starting from the alternating-current side. Method A. The converter in this case is started as an ordinary shunt motor, receiving its current either from a shunt-wound generator or from the direct-current bus-bar. A double-throw switch is usually provided so that the converter may receive current from either source. Ordinarily, when started by current from a shunt-wound generator about two minutes are required to start, to synchronize, and to connect to the bus-bar a 1500-kw. converter. In emergency cases the machine is started by current from the direct-current bus-bar, and only a minute and a half is required to place it in service. The advantages of method A are the rapidity of starting, the smallness of first cost, since it requires but one starting set for all the converters, and the slight expense of maintenance. The disadvantages of the method consist in a small factor of reliability and the possibility of a heavy surging of current during the process of synchronizing. The latter disadvantage, however, may be obviated by the use of a simple modification of the switch-gear, devised by Mr. H. G. Stott. This device is now used in connection with the Interborough Rapid Transit Company's equipments. It consists in closing a local storage-battery through the tripping coil of the circuit-breaker of the starting bus-bar a fraction of a second before the converter oil-switch closes. The converter then runs practically free from the directcurrent side, self-excited, at the instant the oil-switch closes. The oil-switch motor and the tr...
