PLC控制柜有很多種。熟悉電氣控制柜，淄博供水PLC控制柜工程、變頻控制柜、低壓控制柜、高壓控制柜、水泵控制柜、動力控制柜，淄博供水PLC控制柜工程、防爆控制柜、電梯控制柜、PLC控制柜、消防控制柜、BR點(diǎn)擊機(jī)器控制柜等。 </p> <p> <p> 電氣控制柜設(shè)計(jì)的基本思想是邏輯思維。只要符合邏輯控制規(guī)律，能保證電氣安全，滿足生產(chǎn)過程的要求，就可以說是一種良好的設(shè)計(jì)。 </p> <p> 然而，淄博供水PLC控制柜工程，為了滿足電氣控制設(shè)備的制造和使用要求，有必要設(shè)計(jì)合理的電氣控制過程。這些設(shè)計(jì)包括電氣控制柜的結(jié)構(gòu)設(shè)計(jì)、電氣控制柜的總體配置圖、總體接線圖設(shè)計(jì)以及各部分的電氣組裝和接線圖設(shè)計(jì)。 </p> </p>

style="text-indent:25px">對PLC的干擾編輯空間輻射干擾空間的輻射電磁場（EMI）主要是由電力網(wǎng)絡(luò)、電氣設(shè)備的暫態(tài)過程、雷電、無線電廣播、電視、雷達(dá)、高頻感應(yīng)加熱設(shè)備等產(chǎn)生的，通常稱為輻射干擾，其分布極為復(fù)雜。若PLC控制器系統(tǒng)置于所射頻場內(nèi)，就會收到輻射干擾，其影響主要通過兩條路徑：一是直接對PLC內(nèi)部的輻射，由電路感應(yīng)產(chǎn)生干擾；二是對PLC通信內(nèi)網(wǎng)絡(luò)的輻射，由通信線路的感應(yīng)引入干擾。輻射干擾與現(xiàn)場設(shè)備布置及設(shè)備所產(chǎn)生的電磁場大小，特別是頻率有關(guān)，一般通過設(shè)置屏蔽電纜和PLC控制器局部屏蔽及高壓泄放元件進(jìn)行保護(hù)。系統(tǒng)外引線干擾主要通過電源和信號線引入，通常稱為傳導(dǎo)干擾。這種干擾在我國工業(yè)現(xiàn)場較嚴(yán)重。淄博抽油機(jī)PLC控制柜價(jià)格淄博創(chuàng)銀節(jié)能科技有限公司提供周到的解決方案，滿足客戶不同的服務(wù)需要。</p><div

2、三條橫條和一條垂直線。另一端連接防雷接地，一般機(jī)房設(shè)置。如果沒有，電纜將被引出并埋在地下以埋葬鐵架。 </p> <p> 在控制系統(tǒng)中，使用PLC的模擬量來控制多臺變頻器，因?yàn)樽冾l器本身產(chǎn)生的強(qiáng)干擾信號的特性和模擬量的抗干擾能力與數(shù)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(yán)格的措施。 </p> <p> 1.信號線和電源線需要分開。當(dāng)使用模擬信號遠(yuǎn)程控制變頻器時，為了減少變頻器和其他設(shè)備的模擬干擾，請控制變頻器的信號線和強(qiáng)電路(主電路和順序電路分開。距離應(yīng)該大于30cm。即使在控制柜中，也應(yīng)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(nèi)。 </p> <p> 3.模擬控制信號線應(yīng)使用雙絞屏蔽線。 </p> <p> 導(dǎo)線尺寸為0.5至2 mm2。接線時，請務(wù)必注意電纜剝離應(yīng)盡可能短（5-7mm），剝離后的屏蔽層應(yīng)用絕緣膠帶包裹，以防止屏蔽層與其他設(shè)備接觸而引起干擾 </p><p
