電阻屏的局限不管是四線電阻觸摸屏還是五線電阻觸摸屏,它們都是一種對外界完全隔離的工作環(huán)境,不怕灰塵和水汽,它可以用任何物體來觸摸,可以用來寫字畫畫,比較適合工業(yè)控制領(lǐng)域及辦公室內(nèi)有限人的使用。電阻觸摸屏共同的缺點是因為復(fù)合薄膜的外層采用塑膠材料,不知道的人太用力或使用銳器觸摸可能劃傷整個觸摸屏而導(dǎo)致報廢。

若二次側(cè)負(fù)荷大于允許阻抗時,將會影響繼電保護裝置正確和可靠動作,該電流互感器就不能使用。(4)影響電流互感器變比誤差的主要因素,除了一次電流之外,還有二次側(cè)負(fù)荷阻抗。若二次側(cè)負(fù)荷阻抗增大,使二次側(cè)電流去磁安匝數(shù),就會使勵磁電流增大,從而使變比誤差增大。

其光譜范圍也往往比較寬,比較適合進行高質(zhì)量的圖像處理算法,例如機器視覺(MachineVision)應(yīng)用,而普通相機拍攝的圖片,其光譜范圍只適合人眼視覺,并且經(jīng)過了壓縮,圖像質(zhì)量較差,不利于分析處理,工業(yè)相機相對普通相機來說價格較貴。

單相電不能產(chǎn)生磁場.要使單相電動機能自動起來,可在定子中加上一個起動繞組,起動繞組與主繞組在空間上相差90度,起動繞組要串接一個合適的電容,使得與主繞組的電流在相位上相差90度,即所謂的分相原理。這樣兩個在時間上相差90度的電流通入兩個在空間上相差90度的繞組,將會在空間上產(chǎn)生(兩相)磁場,在這個磁場作用下,轉(zhuǎn)子就能自行啟動起來。
