NOVYE USTROISTVA AVTOMATIKI I TELEMEKHANIKI (ELEKTRIFIKATSIIA I ENERGETICHESKOE KHOZIAISTVO, 6(72)

This issue presents (1) a description of the central dispatching point which realizes the centralized control for direct and alternating current conditions of electrified lines, remote control of reserve feeding arrangements, and the realization of direct telephone communication of electrification and energy economy service apparatus road control by means of the energy feeding section dispatchers. New to the central dispatching point is the signaling of the presence of tension in the catenary network feeder cables, the relay junctions of remote control signals, and also the utilization of electroluminescent panels. (2) A description of the new remote control system "Lisna" in which silicon assemblies are maximally utilized; these have high operational reliability. For the remote control by means of energy feeding objectives in this system mosaic-type switchboards are applied. (3) The description of new assemblies for the checkup of toroidal magnetic transformers with rectangular hysteresis loops, silent discharge thyratrons, semiconductor transistors and diodes, and type MO-70P oscillograph. (4) A description of electric protection, the first phase of which is predestined for the feeder cables feeding the station and depot roads, and the second for the feeder cables feeding the section between stations. High-speed action of the electronic protection system is attained by employing discharge and measurement instruments characterized by lower acting time, exclusion from the protective system of intermediate relays, employment of no-contact, disconnecting, high voltage contact breakers and automatic blocking system between adjacent circuit breakers of the substations and sectioning posts. (5) A description of the rapid-acting protection system with output thyristor unit supplemented by current relay with magnetically controlled hermetically sealed contact. The high-speed action of protection and reliability and simplicity of construction allow its utilization not only for the protection of station and depot feeder cables of the catenary network, but also for the protection of all catenary network feeder cables, DPR lines, basic transformers, compensating arrangements, and all other connections.
