海外工程中水轮发电机介损和电容测量试验

在大型汽轮、水轮发电机等大电容设备的测量和检修过程中,常因测量仪器容量不够,而无法适应海外工程特点和满足国内外标准要求。针对此问题,首先分析了串联谐振装置和介质损耗（介损）测量装置的应用原理,然后根据其测量特性,提出了组合应用串联谐振装置和介损测试仪进行水轮发电机介损和电容测量。将该方法应用到印度尼西亚总承包工程的测量试验中,根据国内外标准分析了试验结果。试验研究表明,该方法测量准确、方便,并且试验结果达到了国际标准。

Dielectric Loss and Capacitance Measurement Test of Hydraulic Generator for Overseas Projects

In the measurement and maintenance of equipment with large capacitance, such as large steam turbine and hydraulic turbine driven generators, the capacity of measuring instruments is usually not big enough. So it is unable to fit the characteristics cif overseas projects and meet the requirements of domestic and international standards. According to this problem, operation principles of the series resonant device and the dielectric loss tester are first analyzed. Then dielectric loss and capacitance measurement method is put forward based on the measurement characteristics of both combination of series resonance device and dielectric loss tester. Finally, this method is applied to the measurement test of Indonesia packaged deal project, and the testing results are analyzed in accordance with domestic and international standards. Experimental studies show that this method is accuracy and convenience, and the test results meet international standards.
