The development of a real - time surveillance and automatic switching apparatus for use with a double power supply system 雙供電系統(tǒng)實時監(jiān)控和自動切換裝置的研制
The judgement results are basically coincided with the experimental results , as is a new method of predicting the electrical life of switching apparatus 評判結(jié)果與實驗結(jié)果基本一致,從而為預(yù)測開關(guān)電器的電壽命開創(chuàng)了一條新的途徑。
In the field of medium voltage switch apparatus , vacuum circuit breaker has been widely used for its advantage of oil - free , miniaturized and easy access 在中壓開關(guān)設(shè)備領(lǐng)域中,真空斷路器由于實現(xiàn)了無油化、小型化、便于檢修等優(yōu)點得到了廣泛應(yīng)用。
These results provide basal information and theories data for increasing the solar cell conversion , developing and exploiting the miniature photoelectron switching apparatus 這為提高太陽能的轉(zhuǎn)換與利用以及微型光電子開關(guān)器件的研制、開發(fā)提供了基礎(chǔ)材料和理論數(shù)據(jù)。
The load - control apparatus adopted a single - chip microcomputer system , whose mcu was a kind of high - speed processor - ds80c320 , whose a / d switched apparatus was max180 , whose low - pass filter was max293 , whose f / v transformed circuit was lm331 , whose controlled silicon phase - shift touch - off circuit was tca785 , and whose communicating interface of rs232 was max202 . the watchdog of the mcu was max705 and the system used an on - off electrical source to supply power 球磨機負荷控制儀采用了單片機系統(tǒng), mcu采用ds80c320高速處理器,采用max180作為md轉(zhuǎn)換器,低通濾波器為max293 , f v轉(zhuǎn)換電路利用lm331 ,可控硅移相觸發(fā)電路使用tca785 , rs232通信接口芯片采用max202 , mcu監(jiān)控電路為max705 ,系統(tǒng)使用開關(guān)電源供電。
