Research on High-precision Positioning Technology for Partial Discharge of High Voltage Switchgear

Abstract

With the advancement and development of power technology, the research of high-voltage switchgear has always been a hot issue. Countries around the world are actively conducting related research. Good high-voltage switchgear can have a positive impact on the development of the power grid. This paper studies the partial discharge positioning technology of power system switchgear, introduces the common ground wave and ultrasonic detection of partial discharge technology, and builds the space model of power switchgear, and proposes the use of hyperboloid method and space search method. The positioning technology of the partial discharge of the switchgear is combined with the multi-channel power switchgear detection equipment used in this paper. The effectiveness of the multi-channel switchgear to detect and locate the partial discharge is verified by simulation experiments. This article introduces the principles of high-voltage switchgear diagnosis and collects local high-precision positioning technology. It introduces the most widely used monitoring technology and live TEV AE real-time monitoring technology, and its complex concepts and principles. It can clearly compare two live detection technologies. Existing power companies generally use two mating devices, high-voltage switchgear, to better diagnose the PD phenomenon; they also introduce positioning methods and positioning technologies. The four-channel detection technology is mainly charged and applied positioning methods and positioning Surface space network search method.
