The Research Of Online Test And Fault Diagnose Of Electric Power Transformer

In order to meet with the status and develop demand qf the oilfield electric power system, basing on the many series of transformer and the high performance demand to transformer in oilfield and the fact that measure instruments are incomplete now, by use computer control technology , a suit of oilfield electric power transformer performance and parameter integrated measure system is developed , which is for in-use, standby and choose type . The system ensures transformer to "credibility , safety and economy running.By analyzing transformer criterion and picking up the work criterion and test requirement and process of power transformer test ; According to the requirement of "synthesis function , computer structure , screen watch , intelligence management " , the performance and parameter integrated measure system of oilfield power transformer is designed ; According to the demands of transformer test criterion and computer control technique, the computer test methods are worked out ; Aiming at the special instance of power company , the online measure of short-test in . power transformer test is simulanted in test-room , try to prove that online measure of transformer test is feasible .the test results are satisfaction. In the end, there is software design: the instrumented-test-interface is developed ; location computer entering to sample state is the same time , and after the same "log time " , it stops the data sample note.Every test signal data keeping in the data note memorizer is at the same time , so it realizes data synchronization collection . Some blocking design in the process of software design can apply to the other software.
