DETERIORATION DETECTION DEVICE OF DISTRIBUTING BOARD

摘要

PURPOSE: A deterioration detecting apparatus of a switchgear is provided to increase the accuracy of deterioration determination by detecting an arc and a temperature and using algorithm. CONSTITUTION: An ultraviolet sensor(SS1) senses an arc generated from a connection unit. An infrared temperature sensor(SS2) senses a surface temperature of the connection unit. An ambient temperature sensor(SS3) senses an inner temperature of a switchgear. An arc detector(DT1) digitalizes an arc sensing signal. A connection unit temperature detector(DT2) digitalizes a connection unit temperature signal. An ambient temperature detector(DT3) digitalizes an ambient temperature signal. An input data extractor(IDE) extracts a temperature change ratio between ambient temperatures. An FRBFNN(Fuzzy clustering based Radial Basis Function Neural Network) reasoning unit(AR) produces a deterioration value by using algorithm. A deterioration determining unit(CDE) determines the deterioration of the connection unit of a device.
