在控制系統(tǒng)中，使用PLC的模擬量來控制多臺變頻器，因為變頻器本身產生的強干擾信號的特性和模擬量的抗干擾能力與數字抗干擾性不兼容能力;因此，較大程度地消除逆變器對模擬量的干擾，并在接線和接地方面采取更嚴格的措施，淄博防爆PLC控制柜品牌。 </p> <p> 1.信號線和電源線需要分開。當使用模擬信號遠程控制變頻器時，為了減少變頻器和其他設備的模擬干擾，請控制變頻器的信號線和強電路(主電路和順序電路分開。距離應該大于30cm。即使在控制柜中，也應保持這種接線規(guī)范。信號與變頻器之間的控制電路不得超過50m。 </p> <p> 2.信號線和電源線信號線需要放置在不同的金屬管或金屬軟管內。 </p> <p> 3.模擬控制信號線應使用雙絞屏蔽線。

機箱的通風方案采用了前門下方有風的形式，后門沒有進出的風孔。每個吸氣口設置一個通風濾波器防塵，外形尺寸為320 mm×320 mm，通風面積約008平方米。因為PLC機箱內零件的熱量很少，所以采用自然對流方式就可以了。如果加速風速，對門板上半部分的出口過濾器，追加1個軸流愛好者，向外排出風。 </p> <p> <br /> </p> <p> 選擇線槽規(guī)格 </p> <p> 線槽規(guī)格有很多種。常用的線槽寬度為25mm、40 mm、60 mm、80 mm、100 mm，高度為40 mm、60 mm、80 mm、100 mm，顏色以灰色為。選擇線槽的原則是，將通過線槽的體積之和（包括絕緣層）設為線槽容量的80%左右，選擇線槽的規(guī)格。剩下的空間對線的散熱方便。計算時斷面的關系，即線斷面的和（包括絕緣層）為溝斷面的80%左右。 </p> <p> <br
