The UHF office on - line monitoring system realizes the monitoring analysis and diagnosis function of the partial discharge status of the primary equipment body , and through the IEC61850 communication protocol , the data is sent to the station monitoring system to achieve data collection , forwarding and application , and then reduce the maintenance power failure and fault power failure time , thereby increasing the service life of the main equipment .

(1) Integrated diagnosis platform : This system is based on Al + mechanism + multi - data fusion method , using neural network and pattern recognition algorithm to realize intelligent fault diagnosis and early warning .

(2) Local release acquisition terminal : high - speed acquisition , real - time synchronization , edge computing , fault location .

(3) Intelligent sensing layer : By installing the built - in office discharge sensor at the GIS special plug or installing the external office discharge sensor at the Gls insulator , the partial discharge signal inside the GIS and other high voltage equipment is detected , and the signal is sent to the field acquisition unit LCU through the coaxial cable .
