變頻器是安裝在變頻控制柜內(nèi)部的，這就要求變頻控制柜在設(shè)計(jì)上有了一定的要求，變頻控制柜系統(tǒng)生產(chǎn)廠家給大家講解一下。一，淄博不銹鋼控制柜廠家、散熱問題變頻器的發(fā)熱是由內(nèi)部的損耗產(chǎn)生的。在變頻器中各部分損耗中主要以主電路為主，約占98%，控制電路占2%。為了保證變頻器正?？煽窟\(yùn)行，須對變頻器進(jìn)行散熱我們通常采用風(fēng)扇散熱；變頻器的內(nèi)裝風(fēng)扇可將變頻器的箱體內(nèi)部散熱帶走，若風(fēng)扇不能正常工作，應(yīng)立即停止變頻器運(yùn)行；大功率的變頻器還需要在控制柜上加風(fēng)扇，淄博不銹鋼控制柜廠家，控制柜的風(fēng)道要設(shè)計(jì)合理，所有進(jìn)風(fēng)口要設(shè)置防塵網(wǎng)，排風(fēng)通暢，避免在柜中形成渦流，在固定的位置形成灰塵堆積；根據(jù)變頻器說明書的通風(fēng)量來選擇匹配的風(fēng)扇，風(fēng)扇安裝要注意防震問題。二、電磁干擾問題I.變頻器在工作中由于整流和變頻，周圍產(chǎn)生了很多的干擾電磁波，這些高頻電磁波對附近的儀表、儀器有一定的干擾，而且會產(chǎn)生高次諧波，這種高次諧波會通過供電回路進(jìn)入整個(gè)供電網(wǎng)絡(luò)，淄博不銹鋼控制柜廠家，從而影響其他儀表。如果變頻器的功率很大占整個(gè)系統(tǒng)25%以上，需要考慮控制電源的抗干擾措施。II.當(dāng)系統(tǒng)中有高頻沖擊負(fù)載如電焊機(jī)、電鍍電源時(shí)，變頻器本身會因?yàn)楦蓴_而出現(xiàn)保護(hù)，則考慮整個(gè)系統(tǒng)的電源質(zhì)量問題。淄博不銹鋼控制柜廠家</p><div

現(xiàn)在隨著我國工業(yè)化的進(jìn)程加快，自動化控制柜在更多的工業(yè)生產(chǎn)中得到了的應(yīng)用，這給我們的生產(chǎn)生活帶來了很多的幫助，在很多需要工業(yè)自動化的場合中我們都可以看到自動化控制柜的使用，不過在使用的過程中自動化控制柜容易發(fā)生一些故障，這些故障給我們的生產(chǎn)生活帶來了一定的麻煩，接下來電氣控制柜廠家就來了解一下都容易發(fā)生哪些故障吧。一、自動化控制柜自身故障判斷一般來說，自動化控制柜是可靠的設(shè)備，出故障率很低。自動化控制柜的CPU等硬件損壞或軟件運(yùn)行出錯(cuò)的概率幾乎為零；控制柜輸入點(diǎn)如不是強(qiáng)電入侵所致，幾乎也不會損壞；自動化控制柜輸出繼電器的常開點(diǎn)，若不是**負(fù)載短路或設(shè)計(jì)不合理，負(fù)載電流超出額定范圍，觸點(diǎn)的壽命也很長。因此，我們查找電氣故障點(diǎn)，要放在控制柜的**電氣元件上，不要總是懷疑自動化控制柜硬件或程序有問題，這對快速維修好故障設(shè)備、快速恢復(fù)生產(chǎn)是十分重要的。二、自動化控制柜輸入輸出（I/O）模塊的選取輸出模塊分為晶體管、雙向可控硅、接點(diǎn)型。晶體管型的開關(guān)速度快（一般），但負(fù)載能力小，約、24VDC，適用于快速開關(guān)、信號聯(lián)系的設(shè)備，一般與變頻、直流裝置等信號連接，應(yīng)注意晶體管漏電流對負(fù)載的影響。淄博不銹鋼控制柜公司</p><div

則能很大程度上消除電壓下降。(3)啟動時(shí)需要的功率更低。電機(jī)功率與電流和電壓的乘積成正比,那么通過工頻直接啟動的電機(jī)消耗的功率將高于變頻啟動所需要的功率。在一些工況下其配電系統(tǒng)已經(jīng)達(dá)到了極限，其直接工頻啟動電機(jī)所產(chǎn)生的電涌就會對同網(wǎng)上的其他用戶產(chǎn)生嚴(yán)重的影響,從而將受到電網(wǎng)運(yùn)行商的警告,甚至罰款。如果采用變頻器進(jìn)行電機(jī)起停,就不會產(chǎn)生類似的問題。(4)可控的加速功能。變頻調(diào)速能在零速啟動并按照用戶的需要進(jìn)行均勻地加速，而且其加速曲線也可以選擇(直線加速、S形加速或者自動加速)。而通過工頻啟動時(shí)對電機(jī)或相連的機(jī)械部分軸或齒輪都會產(chǎn)生劇烈的振動。這種振動將進(jìn)一步加劇機(jī)械磨損和損耗，降低機(jī)械部件和電機(jī)的壽命。另外，變頻啟動還能應(yīng)用在類似灌裝線上，以防止瓶子倒翻或損壞。(5)可調(diào)的運(yùn)行速度。運(yùn)用變頻調(diào)速能優(yōu)化工藝過程，并能根據(jù)工藝過程迅速改變，還能通過遠(yuǎn)控PLC或其他控制器來實(shí)現(xiàn)速度變化。</p><p> 可控硅型優(yōu)點(diǎn)是無觸點(diǎn)、具有交流負(fù)載特性，負(fù)載能力不大。繼電器輸出具有交直流負(fù)載特點(diǎn)，負(fù)載能力大。常規(guī)控制中一般首先選用繼電器觸點(diǎn)型輸出，缺點(diǎn)是開關(guān)速度慢，一般在10ms左右，不適于高頻開關(guān)應(yīng)用。三、接地問題自動化控制柜系統(tǒng)接地要求比較嚴(yán)格，要有**的**接地系統(tǒng)，還要注意與控制柜有關(guān)的其他設(shè)備也要可靠接地。多個(gè)電路接地點(diǎn)連接在一起時(shí)，會產(chǎn)生意想不到的電流，導(dǎo)致邏輯錯(cuò)誤或損壞電路。而產(chǎn)生不同的接地電勢的原因，通常是由于接地點(diǎn)在物理區(qū)域上被分隔的太遠(yuǎn)，當(dāng)相距很遠(yuǎn)的設(shè)備被通信電纜或傳感器連接在一起的時(shí)候，電纜線和地之間的電流就會流經(jīng)整個(gè)電路，即使在很短的距離內(nèi)，大型設(shè)備的負(fù)載電流也可以在其與地電勢之間產(chǎn)生變化，或者通過電磁作用直接產(chǎn)生不可預(yù)知的電流。在不正確的接地點(diǎn)的電源之間，電路中有可能產(chǎn)生毀滅性的電流，以至于破壞設(shè)備。自動化控制柜系統(tǒng)一般選用一點(diǎn)接地方式。為了提高抗共模干擾能力，對于模擬信號可以采用屏蔽浮地技術(shù)，即信號電纜的屏蔽層一點(diǎn)接地，信號回路浮空，與大地絕緣電阻應(yīng)不小于50MΩ。四、消除線間電容避免誤動作電纜的各導(dǎo)線間都存在電容，合格的電纜能把此容值限制在一定范圍之內(nèi)。</p><div

首先，PLC控制柜包括兩個(gè)部分，軟件部分和硬件部分，硬件部分是即是我們?nèi)庋劭梢姷膶?shí)實(shí)在在的可以觸摸到的部分，其中包括PLC，各種電器元器件，鏈接電纜，施工材料；軟件部分有整個(gè)系統(tǒng)的設(shè)計(jì)費(fèi)，軟件的編寫，包括現(xiàn)場調(diào)試的費(fèi)用。一：硬件部分根據(jù)客戶提出的不控制要求我們要選配相應(yīng)功能的電器元件，根據(jù)客戶的不同品牌要求選擇國產(chǎn)或是進(jìn)口的，具有同樣使用功能的元器件可能由于不同品牌而存在較大價(jià)格差異。選用元器件時(shí)電氣控制柜廠家推薦客戶選擇國產(chǎn)或者進(jìn)口產(chǎn)品中使用性比較普遍的**品牌，這可以保證產(chǎn)品的質(zhì)量以及可追溯性，有些**品牌的產(chǎn)品市場上存在一些仿品，需要消費(fèi)者擦亮眼睛，選擇有正規(guī)資質(zhì)的代理商或者是經(jīng)銷商。二：軟件部分的價(jià)格是要根據(jù)整個(gè)系統(tǒng)的大小，控制要求的復(fù)雜程度來決定的?，F(xiàn)場調(diào)試費(fèi)用又根據(jù)使用現(xiàn)場的遠(yuǎn)近以及調(diào)試時(shí)間的情況來決定，比如熟練的工程師可能一次就能搞定的事情，有些不太熟練或者相對經(jīng)驗(yàn)不太豐富的工程師，可能需要2-3天甚至4-5天，無形中成本就增加了。整個(gè)系統(tǒng)能不能順利的運(yùn)行起來，能不能符合當(dāng)初提出的控制要求，能不能對程序進(jìn)行后續(xù)的再編寫，都是依靠軟件部分來實(shí)現(xiàn)的！淄博不銹鋼控制柜廠家</p><p style="text-indent:25px">淄博不銹鋼控制柜廠家</p><p> 一般來說，變頻控制柜系統(tǒng)的設(shè)計(jì)一般包括七個(gè)方面，以便更好的進(jìn)行工作，電氣控制柜廠家就為大家簡單介紹一下，關(guān)于控制柜的控制系統(tǒng)的相關(guān)內(nèi)容介紹。1、明確設(shè)計(jì)任務(wù)和技術(shù)條件。設(shè)計(jì)任務(wù)和技術(shù)條件一般以設(shè)計(jì)任務(wù)書的方式給出，在設(shè)計(jì)任務(wù)書中，應(yīng)明確各項(xiàng)設(shè)計(jì)要求、約束條件及控制方式。因此，設(shè)計(jì)任務(wù)書是整個(gè)系統(tǒng)設(shè)計(jì)的依據(jù)。2、選擇可編程控制器的機(jī)型?？删幊炭刂破魇钦麄€(gè)控制系統(tǒng)的部件，正確、合理地選擇機(jī)型對于保證整個(gè)系統(tǒng)的技術(shù)經(jīng)濟(jì)性能指標(biāo)起著重要的作用。此外，它還提示PLC的選型包括機(jī)型的選擇、存儲器容量的選擇、I/O模塊的選擇等。3、確定用戶輸入設(shè)備和輸出設(shè)備。用戶的輸入、輸出設(shè)備是構(gòu)成PLC控制系統(tǒng)中除了作為控制器的PLC本身以外的硬件設(shè)備，是進(jìn)行機(jī)型選擇和軟件設(shè)計(jì)的依據(jù)。因此，要明確輸入設(shè)備的類型(如控制按鈕、行程開關(guān)、操作開關(guān)、檢測元件、保護(hù)器件、傳感器等)和數(shù)量、輸出設(shè)備的類型(如信號燈、接觸器、繼電器等執(zhí)行元件)和數(shù)量以及由輸出設(shè)備驅(qū)動的負(fù)載(如電動機(jī)、電磁閥等)，并進(jìn)行分類、匯總。4、山東PLC控制系統(tǒng)具有分配I/O通道，繪制I/O接線圖。通過對用戶輸入、輸出設(shè)備的分析、分類和整理，進(jìn)行相應(yīng)的I/O通道分配。淄博不銹鋼控制柜廠家</p><p
