low-factor line
解釋
低功率因數線路-
Manual measure tools, such as micrometer were used to measure outside and inside diameter of tube product, which is effected by people factor and has long measuring period and low precision and dose not fulfill the on - line measuring need of batch production. so, according to the product line structure of tube product, the on - line measuring method with linear ccd is brought forward in this article and imitating operation is done by the mentioned method
傳統的對管狀產品的檢測方法是利用千分尺等工具手工測量，測量周期長、準確度不高且受人為因素影響大，不能滿足批量生產的在線檢測要求。為此，本文根據所研究管狀產品的生產線結構，提出了一種以線掃描ccd攝像機為基礎的在線檢測方法並對此方法進行模擬計算。 -
The conventional switching power supply usually use a diode rectifier followed by a bulk capacitor to convert ac voltage to dc voltage, resulting in the pulsating waveform of the input ac line current, low power factor ( generally 0. 65 ) and high harmonic line current
傳統的開關電源設備通常採用二極體橋來進行整流和一個較大的電解電容來進行濾波以實現輸入電壓的交直流轉換，導致輸入電流為一個很窄的脈沖波並含有較多的諧波分量，功率因數變低（通常只有0 . 65 ） 。 -
The manual measurement has been adopted for a long time, which is greatly affected by artificial factor resulting in low measuring precision and ca n ' t be processed by automatic line
原木分等一直是林業生產和加工等部門的一個關鍵環節，長期以來所使用的方法是人工檢測。人工檢測受人為因素影響很大，工作效率低，不能形成自動化的生產線。 -
The input of traditional ac - dc converter is diode - capacitance combined circuit. it ? input current wave presents pulse shape, and the power factor ( pf ) on ac line side is low
傳統的ac ? dc開關變換器輸入端是二極體整流-濾波電容組合電路，其輸入電流波形呈脈沖狀，交流網側功率因數很低。 -
Its test results indicate : voltage mode inverters with high frequency link have the advantages such as high frequency electrical isolation, simple topology, two - stage power conversions, high power density, bidirectional power flow, good line current waveform, low audio noise, high converting efficiency, and high input power factor etc. this kind of converter lay the key technical foundation on new type high power density, high efficiency and low cost asi
設計的1kva270v 10 % dc / 115v400hzac單極性移相控制雙向電壓源高頻環節逆變器原理試驗表明，這類逆變器具有高頻電氣隔離、電路拓撲簡潔、兩級功率變換（ lfac / hfac / lfac ） 、功率密度高、雙向功率流、音頻噪音低、變換效率高、網側功率因數高等優點，為新一代高功率密度、高變換效率、低成本航空靜止變流器奠定了關鍵技術基礎。
