摘要
从电源电压施加方式、测试仪表等方面对变压器空载试验结果的影响因素进行了分析,指出了在变压器空载试验中应该注意的相关因素,如要克服试验电源波形畸变,增大试验电源容量等;总结了现场工作中如何有针对性地减小测量误差来保证试验结果的准确性,如将实测的变压器空载损耗值减掉仪表损耗值等。
The influencing factors on results of transformer no-load test were analyzed,such as the voltage mode of power source and test instrument.The related factors that should be noticed in transformer no-load test were pointed out,such as to surmount the test waveform distortion of power source and to increase the test capacity of power source.The paper summarized how to reduce measuring error and to ensure the accuracy of test result,for example,the loss value of test instrument can be reduced from the actual m...
