機(jī)箱的通風(fēng)方案采用了前門下方有風(fēng)的形式，后門沒有進(jìn)出的風(fēng)孔。每個(gè)吸氣口設(shè)置一個(gè)通風(fēng)濾波器防塵，外形尺寸為320 mm×320 mm，通風(fēng)面積約008平方米。因?yàn)镻LC機(jī)箱內(nèi)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(fēng)速，對門板上半部分的出口過濾器，追加1個(gè)軸流愛好者，向外排出風(fēng)。 </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(shè)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(jì)算時(shí)斷面的關(guān)系，即線斷面的和（包括絕緣層）為溝斷面的80%左右。 </p> <p> <br />

1.豐富的I\/O卡控制器具有相應(yīng)的I\/O模塊和工業(yè)現(xiàn)場設(shè)備或裝置，例如按鈕、行程開關(guān)、接近開關(guān)、模擬信號(hào)、電壓或電流、脈沖或電位、強(qiáng)弱電流，用于工業(yè)自動(dòng)控制系統(tǒng)的不同現(xiàn)場信號(hào)。控制工程，如：通信或直流；開關(guān)或模擬信號(hào)；電壓或電流；脈沖或電位；強(qiáng)弱電流等。傳感器和發(fā)送器、電磁線圈、控制閥等直接連接。為了提高操作功能，它還具有多種人機(jī)對話接口模塊；為了形成一些工業(yè)網(wǎng)絡(luò)，它還具有多種通信網(wǎng)絡(luò)接口模塊等。 </p> <p> 2.控制系統(tǒng)采用模塊化結(jié)構(gòu)，滿足各種工業(yè)控制的需要。除小單元控制器外，大多數(shù)控制器采用模塊化結(jié)構(gòu)?？刂破鞯母鱾€(gè)部件，包括CPU、電源和I\/O，均采用模塊化方案。每個(gè)模塊通過框架和電纜連接。系統(tǒng)的方案和功能可根據(jù)用戶需要自行組裝。 </p> <p> 3.價(jià)格優(yōu)勢，質(zhì)優(yōu)價(jià)廉，性價(jià)比高。 </p> <p> 4.設(shè)備簡單，維修方便。它可以直接在各種工業(yè)環(huán)境中工作。使用時(shí)，現(xiàn)場各種設(shè)備可與PLC相應(yīng)的I\/O終端連接投入運(yùn)行。各種模塊都有工作和缺點(diǎn)指示設(shè)備，方便用戶了解工作情況，發(fā)現(xiàn)缺點(diǎn)。 </p> <p> 由于模塊化結(jié)構(gòu)的原因，一旦某個(gè)模塊存在一些缺點(diǎn)，用戶就可以對該模塊進(jìn)行修改，使系統(tǒng)能夠靈敏地工作。 </p><p> PLC控制柜的接地方法是什么？ </p> <p> 1、設(shè)備后面有一個(gè)接地點(diǎn)和接地標(biāo)志。 </p> <p> 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(tái)變頻器，因?yàn)樽冾l器本身產(chǎn)生的強(qiáng)干擾信號(hào)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(hào)線和電源線需要分開。當(dāng)使用模擬信號(hào)遠(yuǎn)程控制變頻器時(shí)，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(hào)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(hào)與變頻器之間的控制電路不得超過50m。 </p> <p> 2.信號(hào)線和電源線信號(hào)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(hào)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(shí)，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)備接觸而引起干擾淄博創(chuàng)銀節(jié)能科技有限公司生產(chǎn)的產(chǎn)品受到用戶的一致稱贊。</p><div style="width:100%;text-align: center;"><img
