| GIS(Gas Insulated Switchgear)——Gas insulated switch combined electricalequipment, with its small, beautiful appearance, convenient installation, theadvantages of small area occupation, good performance, has been applied more andmore widely in electric power system. GIS is a totally enclosed combined electricalequipment, fault sensory detection of early can not depend on person, GIS interiorequipment arrangement is very compact, fault device is easy to spread to neighboringdevices, so that the expansion of the fault. And repair of GIS equipment failure isoften very complex, time to repair can take two weeks or longer. Therefore, theoperating system is very important, need preventive test routine, combined with GISonline monitoring technology, so that the fault and abnormal happens to discover.This paper studied the application of ultrasonic detection technology in the GISfault. The application status of generating process of GIS inner partial discharge andits detection method. The application of ultrasonic technology for the overall schemefor the detection of partial discharge in GIS. To build the GIS model and its detectionsystem. Analysis of typical faults of GIS partial discharge ultrasonic. Applicationresults illustrate the partial discharge ultrasonic detection technology in GISproduction process. |
