Research on Key Technology of New Type High Voltage Fast Switching Device Without Disturbing Power Supply

Abstract

Fast switching is closely related to the electrical safety, and is of great significance in the continuous production of large and medium-sized chemical enterprises. Quick power switching is mainly composed of quick action of controllers and actuators. At present, the research on effective speed raising of implementation mechanism for high voltage level is relatively blank. Based on a fast switching device for 72.5kV without disturbance power supply, this article completely introduces its key technology, including discriminant algorithm and driving technology. In addition, an experiment result is given to show that it is fast and feasible.
