The invention discloses a fault oscilloscope networking of an intelligent transformer station integrated monitoring system. In the intelligent transformer station integrated monitoring system, fault oscilloscopes in a transformer station, after concentrated individual networking, are then accessed to a station control layer network; a data communication gateway machine and a comprehensive application server respectively communicate with the fault oscilloscopes through the station control layer network; the multiple fault oscilloscopes in the station communicate with a main station at a scheduling end through one scheduling data network IP address by using a PAT (port address translation) technology on the data communication gateway machine; and the comprehensive application server is in charge of acquiring fault oscilloscope data in a concentrated mode so as to realize analysis and processing of the fault oscilloscope data in the station.
