電壓突降 的英文怎麼說
中文拼音 [diànyātūjiàng]
電壓突降
英文
power sags-
Secondly the detection precision is only related to the synchronization phase but not to the amplitude of the mainline voltage because that it uses the optimized pulses synchronous with the mainline voltage as modulation signals. thirdly it decreases the requirement of the input low pass filter and eliminates the error resulting from the direct component and even harmonics of load current. the most significant merit is that it can eliminate the effect of a few low order odd harmonics and the detecting circuit is easy to be implemented
模擬和實驗結果表明該方法的主要優點有：不需使用乘法器進行信號調制，調制信號採用與電網電壓同步的優化特定脈沖，其檢測精度只與同步相位有關，而與電網電壓幅值無關；降低了對輸入低通濾波器的通頻帶要求，直流和偶次諧波分量對檢測精度沒有影響；突出的優點是可以消除有限個低奇次諧波對檢測結果的影響。Battery bottom plumping up, belly protruding, even leakage, what are possibly the causes
電池充滿電時，溫度為什麼會急升，電壓為什麼會突降？The results show that as the voltage rises, the tubes ’ discharge mechanism changes from glow discharge to arc discharge, the current rises suddenly and the voltage drops a lot
結果表明，隨著電壓的升高，六硼化鑭放電管的放電機理由輝光放電轉變為弧光放電，放電電流突然迅速升高，管壓降大幅下降。The conclusion is drawn that in the quasi two - stage compression heat pump system coupled with ejector, discharge temperature of the compressor is decreased effectively, electric power is reduced, and heating performance is increased compared with those of the flash - tank throttle system in the same conditions. it shows that the quasi two - stage compression heat pump system coupled with ejector improves performances of air - source heat pump in theory
由結果可以看出:在相同工況下，準二級壓縮?噴射復合熱泵系統可以有效降低壓縮機排氣溫度，所消耗的電功率較閃發器節流系統有所降低，制熱性能有所增加，從理論上說明該系統在解決空氣源熱泵低溫適應性問題上有進一步突破。It is found that after stressed by surges the varistors show a decrease in both break - down voltage and nonlinear exponent, and an increase in leakage current
實驗結果顯示，氧化鋅變阻器受突波侵襲后，會生成崩潰電壓降低，非歐姆指數值減小，以及漏電流增加等劣化現象。Protection against stress. velvet antler helps the body to maintain homeostasis against heat, cold, and electric shock. this has been linked to velvet antler ' s ability to decrease mast cell degranulation
保護應急能力：鹿茸具有幫助人體應對過熱，過冷，壓抑，氣候突變或電刺激維持體內平衡。這與鹿茸降低肥大細胞的降解有關，肥大細胞是人體主要免疫細胞。Traditional direct torque control uses two value torque regulator which makes zero voltage vector work long and make flux shape bad seriously and makes response time long when the speed of induction motor is very low or drops down quickly. in order to solve this problem the thesis puts forward a new way to use three - value torque regulator, when the motor speed is very low or drops down quickly, the contrary voltage vector is used instead of zero voltage vector and the between the stator flux and rotor flux is reduced quickly so that torque is reduced quickly and response time becomes shorter
為此，本論文提出三點式轉矩調節，這樣當電機低速運轉或給定轉速突降時，不是加零電壓矢量，而是加反方向的電壓矢量，使定子磁鏈與轉子磁鏈之間的夾角迅速減小，從而使電磁轉矩也迅速減小，大大減小了調速時間，同時磁鏈值仍然保持基本恆定，輸出比較穩定的電磁轉矩，這在電機制動過程中非常有用。分享友人
