UHF PARTIAL DISCHARGE AND TEMPERATURE MONITORING SYSTEM EMBEDDED SWITCHGEAR SYSTEM

摘要

The present invention relates to switchgear system provided therein with a UHF partial discharge and temperature monitoring system. An objective of the present invention is to diagnose a partial discharge by comparing a temperature rising trend curve converted based on data visualized by mapping a size and a frequency of a charge quantity of a partial discharge detected through a UHF sensor so that a timely and an accurate diagnosis and repair with respect to electrical power devices installed inside the switchgear is performed to stably operate an electrical power facility and prevent blackouts. The present invention to achieve the objective includes: a UHF sensor to detect a partial discharge signal of a switchgear; a partial discharge monitoring device to amplify the partial discharge signal detected from the UHF sensor and to convert the partial discharge signal into a digital signal, and to accumulate the data to transmit the accumulated data to a partial discharge diagnosis device; a temperature sensor to measure a temperature inside the switchgear in real-time; a temperature monitoring device to amplify the temperature data measured from the temperature sensor and to convert the temperature data into a digital signal, and to transmit the data to the partial discharge diagnosis device; and the partial discharge diagnosis device to diagnose the partial discharge by mapping a size and a frequency of a charge quantity of the partial discharge detected from the partial discharge monitoring device, and comparing a temperature rising trend curve converted based on the temperature data inputted from the temperature monitoring device.
