The purpose of research - to provide maximum electrical and thermal efficiency, and ensure the necessary dynamics of heating with such a semiconductor frequency converter, which is without frequency tuning control can work effectively with any inductor electro-thermal plant with a capacity of 250 kW. In carrying out the work developed a schematic block diagram of an electrical protection and control locking semiconductor transducer installation ETU-250, namely block overcurrent protection; a delay circuit for switching contactor K1; the control circuit mode heating parts; pulse generating circuit control IGBT-transistors, power modules; units specialized secondary power source; locking scheme works power inverter; unit temperature control transistor power modules; the relay semiconductor transducer to generate a signal "Alarm". A layout diagrams and physical simulation mode of the basic units of blocks protection, blocking and monitoring, as well as specialized sources of supply. The preliminary design of the main circuit board of the experimental units of protection, blocking and monitoring semiconductor transducer installation EТU-250 and are made of mock samples for testing experimental units developed in the laboratory.5481 Product Description popup.authors Монастирський Зеновій Ярославович Олігов Євген Володимирович Слинько Володимир Мефодійович Стяжкін Віталій Павлович Чопік Василь Васильович popup.nrat_date 2020-04-02 Close
