Abstract

The design of the linear-drive induction-dynamic mechanism used in high-speed breakers is presented. The research mechanism consists of a coil with leads and a moving disk. The coil of the mechanism is wound with copper tape, the disk is made of copper bus and mounted on the rod, which passes through the hole of the coil. A circuit diagram of a laboratory test bench for the study of the induction-dynamic mechanism has been developed and the principle of operation of the circuit has been considered. A description of the electrical circuit elements is given. A prototype model of the induction-dynamic mechanism was manufactured and a mobile laboratory stand was assembled with the necessary devices mounted on a DIN-rail and ancillary accessories. The high speed of the induction-dynamic mechanism is ensured by the presence of a storage capacitor, which discharges the stored energy to the mechanism coil in a relatively short time. Auxiliary parts for mounting the elements of the stand are made using a modern 3D printer FLASHFORGE CREATOR PRO. Oscillograms of transients are obtained when an induction-dynamic mechanism is triggered, namely: oscillograms of current in the mechanism winding and of voltage on a storage capacitor as well as oscillogram of moving disk displacement. The laboratory stand is used in the educational process as a component of the laboratory workshop on the discipline "Electrical Apparatus".
