PARTIAL DISCHARGE MONITORING AND DIAGNOSIS SYSTEM FOR INTELLIGENT DISTRIBUTION BOARD USING ULTRA FREQUENCY SIGNAL

摘要

The present invention relates to an intelligent switchboard partial discharge monitoring and diagnosis system using ultra-high frequency electrical signals, and more particularly, to power facilities such as high-voltage cables, transformers, GIS (Gas Insulated Switchgear), switchgear, switchgear, electric motors, and generators. It relates to an intelligent switchboard partial discharge monitoring and diagnosis system using ultra-high frequency electrical signals that can diagnose partial discharge while quickly detecting partial discharge due to poor insulation, poor connection, or disconnection using a UHF (Ultra High Frequency) sensor. . The intelligent switchboard partial discharge monitoring and diagnosis system using ultra-high frequency electrical signals according to the present invention for solving the above problems is a high-voltage cable, transformer, GIS (Gas Insulated Switchgear, gas insulated switchgear), any one or more of a switch and a power receiving facility. a detection device for detecting a partial discharge occurring in a switchboard including; a signal processing device for converting the signal transmitted from the detection device into a digital signal and transmitting the converted signal; and a monitoring device for diagnosing and analyzing the digital signal transmitted from the signal processing device, wherein the detection device is installed in the switchboard and generated by partial discharge in the power facility using microwaves of 300 MHz to 3 GHz It is characterized in that it comprises a UHF (Ultra High Frequency) module for detecting the electrical signal of the super high frequency.
