用法例句

The article makes a theoretic analysis based on current waveforms of several types of locomotives′ no load turn-on tests,combines with the characteristic data of type TM2 locomotive,calculates and simulates the no load turn-on current waveform of the locomotive,and then gets the existing reason for the no load turn-on current.

对几种电力机车空载合闸试验测试的电流波形进行理论分析,结合TM2型电力机车相关参数进行计算,并模拟出其空载合闸电流的波形,得出产生空载合闸电流的原因,提出了解决空载合闸电流造成的跳主断误保护现象的建议。
