Устройство мягкого пуска для системы электродвижения

Abstract

Object and purpose of research. Soft start devices (SSD) are designed for autonomous electric power systems to prevent in-rush currents caused by saturation of magnetic circuit of power transformers and frequency converters capacitors charge. Materials and methods. A graphical description of the process is given, accompanied by in-rush currents upon switch-on, and a circuit design, on the basis of which a soft start is carried out for transformers of the main switchgear (MSG). Main results. Schematic diagrams and design documentation of the SSD have been developed, the internal view of the device in as-delivered configuration is given. Conclusion. The SSD device has passed acceptance tests and is ready for delivery for further operation.
