描述

WEIDMULLER 7901620000
交流變頻調(diào)速之所以比直流調(diào)速廣泛運(yùn)用是因?yàn)榻涣麟姍C(jī)，不是變頻調(diào)速原理具有優(yōu)越性，變頻調(diào)速只能應(yīng)用于調(diào)速，而對(duì)力矩是無法做到精確控制的，原因很簡單，直流調(diào)速的電樞和勵(lì)磁不是耦合的，是分開的，這樣對(duì)電樞電流和勵(lì)磁電流能夠做到精確控制。而交流調(diào)速，電樞電流和勵(lì)磁電流是耦合的，是無法做到精確控制的，盡管目前的變頻調(diào)速具有矢量控制，也就是運(yùn)用現(xiàn)代控制理論，通過矢量轉(zhuǎn)換，將交流電機(jī)中耦合的電樞電流和勵(lì)磁電流解開，從而對(duì)其進(jìn)行控制，也就是仿真直流調(diào)速的原理。但是要做到直流調(diào)速的控制特性目前是很困難的。因此在軋機(jī)、造紙等對(duì)力矩要求很高行業(yè)，直流調(diào)速還是具有廣泛性。而僅對(duì)速度控制，目前變頻調(diào)速是可以逼真直流調(diào)速的特性，因?yàn)榻涣麟姍C(jī)的優(yōu)越性是直流電機(jī)無法做到的。直流電機(jī)的電刷和體積的原因，限制了它的應(yīng)用范圍，變頻調(diào)速可以說是由風(fēng)機(jī)和水泵發(fā)展而來的，是由于風(fēng)機(jī)和水泵節(jié)能的需要，變頻調(diào)速是最佳選擇，不過我個(gè)人認(rèn)為就目前電價(jià)和變頻器的自身的價(jià)格相比，這種節(jié)能是毫無意義的，因?yàn)橐炎冾l器的投資收回，最少需要5-6年，在這5-6年的時(shí)間里，工況還不知道要發(fā)生什么變化。零線在變壓器端是和大地相聯(lián)的，由于從變壓器到用戶的零線有一定的電阻，所以在用戶端零線和地之間電壓往往不為零，假如沒有地線的話，若電器發(fā)生故障，零線或火線與用電器金屬外殼連接，那么用電器和大地之間的電壓就不為零，所以是不安全的，這時(shí)如果零線斷開的話，那么是很危險(xiǎn)的。地線是用戶就近接地的一條線，在正常情況下與大地的電壓為零，良好的地線與用電器的金屬外殼相連，在電器發(fā)生故障時(shí)，能確保外殼與地的電壓為零，這樣就起了安全保障作用。

選擇深圳長欣，選擇放心，售后無憂大量現(xiàn)貨，當(dāng)天順豐發(fā)貨！
主營：本特利，英維思，伍德沃德，?？怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂，ACSO，力士樂等各大品牌的DCS系統(tǒng)配件，機(jī)器人系統(tǒng)配件，大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”（不管能不能看懂，先了解個(gè)大概，以便學(xué)習(xí)編程時(shí)查找）；
2、由位控邏輯入手，逐漸增加定時(shí)、計(jì)數(shù)等條件，把或、與、非關(guān)系理順；
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換；
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解（最好是有個(gè)物理回路驗(yàn)證，比如變頻器+電機(jī)+測速傳感器）；
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制（盡量避免跳轉(zhuǎn)，非跳不可時(shí)也是跳的越近越好）；
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列，GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌，由于PLC的基本框架大同小異，學(xué)會(huì)一種至于其它的學(xué)習(xí)起來也就簡單了。
