transformer ratio中文什么意思
例句與用法
- Transformer ratio measurement
變壓比測定 - On the same winding , at most three taps can be made to form four transformer ratios , but the difference between maximum current and minimum current should not exceed one time ( for example : 150 - 200 - 250 - 300 / 5a )
在同一個(gè)繞組上最多可三次抽頭，組成四變比，但最大電流與最小電流相差不能超過一倍（如： 150 - 200 - 250 - 300 / 5a ） 。 - The rbf network has a better performance , and better forecasting accuracy . then mathematical model of substation voltage / var control is constructed , the squares minimization of voltage differences as target , also considering requirement of voltage and power balance , taking it into consideration that the magnitude constraint of transformer ratio and compensating capacitor , also that constraint of operation times of one day transformer tap and capacitor switch
因此提高了學(xué)習(xí)性能，具有較好的預(yù)測精度。然后，建立變電站電壓無功控制的數(shù)學(xué)模型，考慮電壓的調(diào)壓要求和無功功率平衡，計(jì)及變壓器變比和并聯(lián)補(bǔ)償電容的上下限約束，變壓器分接頭和電容器允許的日調(diào)節(jié)次數(shù)的限制，以電壓偏差的平方和最小為目標(biāo)函數(shù)。 - The mechanical impedance analyzing method utilized , the mathematical formula for the input impedance and transformer ratio of ultrasonic horn are built up , some vibration performance of ultrasonic horns are discussed under different load impedance , the relationship and applicational conditions between the transformer ratio of ultrasonic horn and the radiational impedance are analyzed
采用機(jī)械阻抗分析方法，建立了超聲變幅器的輸入阻抗和變幅比的數(shù)學(xué)表達(dá)式，討論了不同負(fù)載阻抗下超聲變幅器的振動性能，分析了超聲變幅器的變幅比與換能器輻射阻抗之間的關(guān)系及應(yīng)用條件。
