F3CU04-1S

干式變壓器:依靠空氣對(duì)流進(jìn)行自然冷卻或增加風(fēng)機(jī)冷卻,多用于高層建筑、高速收費(fèi)站點(diǎn)用電及局部照明、電子線路等小容量變壓器。干式:絕緣介質(zhì)為環(huán)氧樹(shù)脂、浸漬漆、杜邦紙網(wǎng)格布、空氣等,散熱介質(zhì)為空氣等(無(wú)滲漏,受到生設(shè)備等的限制一般用于35kV級(jí)及以下,容量不是很大,成本較高)
油浸式變壓器:依靠油作冷卻介質(zhì)、如油浸自冷、油浸風(fēng)冷、油浸水冷、強(qiáng)迫油循環(huán)等。油浸式:絕緣介質(zhì)為變壓器油、紙板等,散熱介質(zhì)為變壓器油等(有可能會(huì)滲漏,環(huán)保性差了一點(diǎn),成本低一點(diǎn))
變壓器(Transformer)是利用電磁感應(yīng)的原理來(lái)改變交流電壓的裝置,主要構(gòu)件是初級(jí)線圈、次級(jí)線圈和鐵芯(磁芯)。主要功能有:電壓變換、電流變換、阻抗變換、隔離、穩(wěn)壓(磁飽和變壓器)等。按用途可以分為:電力變壓器和特殊變壓器(電爐變、整流變、工頻試驗(yàn)變壓器、調(diào)壓器、礦用變、音頻變壓器、中頻變壓器、高頻變壓器、沖擊變壓器、儀用變壓器、電子變壓器、電抗器、互感器等)。電路符號(hào)常用T當(dāng)作編號(hào)的開(kāi)頭.例:T01,T201等。任何電氣系統(tǒng)的公用電路出故障,其能量、信息就無(wú)法傳送、分配到各具體專用電路,專用電路的功能、設(shè)備管理中華聯(lián)盟,性能就不起作用。如一個(gè)電氣設(shè)備的電源出故障,整個(gè)系統(tǒng)就無(wú)法正常運(yùn)轉(zhuǎn),向各種專用電路傳遞的能量、信息就不可能實(shí)現(xiàn)。因此遵循先公用電路、后專用電路的順序,就能快速、準(zhǔn)確地排除電氣設(shè)備的故障。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國(guó)內(nèi)實(shí)力庫(kù)存商家


選擇深圳長(zhǎng)欣,選擇放心,售后無(wú)憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營(yíng):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(mén)子、摩托羅拉、GE發(fā)那科、安川、博世力士樂(lè),ACSO,力士樂(lè)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(cè)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(lái)也就簡(jiǎn)單了。
