DEVICE FOR PROTECTION AGAINST TWO-PHASE RETARDATION AND OVERLOAD FOR THE ELECTRICAL ENERGY RECEIVERS

摘要

the invention relates to a protection device for overload in two phases and the whereabouts of electricity in which receptor currents of the phases.picked off by transformers are introduced in a triple phase rectifier connected through a transformer to a rectifier to a threshold circuit for single-phase operating a logic circuit and amplifierwhat command through a thyristor a relay protection circuit which is acted by a second threshold circuit and a diode current of the phase.being made from a supply through a rectifier, phase stabilizer, and signalling of product damage being secured with light-emitting diodes.
