描述

NW-BM85-000
電力電纜在施工中,有采用鋼支架的,有采用鋼質(zhì)保護(hù)管的,有采用電纜卡與架空敷設(shè)的,凡是在電力電纜周圍形成鋼(鐵)性閉合回路的,均有可能形成渦流,特別是在大電流電力電纜系統(tǒng)中,渦流更大。在電力電纜施工時(shí),必須采取措施,使電纜周圍不能形成鋼(鐵)性閉合回路,防止電纜引起渦流現(xiàn)象發(fā)生。由于電力電纜外徑較大,運(yùn)輸、敷設(shè)較為困難,電力電纜對(duì)轉(zhuǎn)彎半徑的要求也比較嚴(yán)格。電力電纜在施工中,如果轉(zhuǎn)彎角度過(guò)大,可能使導(dǎo)體內(nèi)部受到機(jī)械損傷,而機(jī)械損傷因被電纜絕緣強(qiáng)度下降,直到出現(xiàn)故障,施工中發(fā)現(xiàn)一次電纜頭故障,在電纜頭制作時(shí),三根電纜頭長(zhǎng)度一致,與設(shè)備連接時(shí)由于受地形限制,中相電纜頭偏長(zhǎng)而成為拱形,電纜頭根部受損放電。
后采取措施,在設(shè)備的連接,適當(dāng)縮短中相電纜頭連接長(zhǎng)度,使三相電纜頭均不受外力,實(shí)踐證明運(yùn)行效果良好。由此可見(jiàn),電纜施工過(guò)程中,要盡可能減少電纜受到的扭力,在電纜轉(zhuǎn)彎和裕留電纜時(shí),讓電纜處于自然彎曲,杜絕內(nèi)部機(jī)械損傷現(xiàn)象。?運(yùn)行經(jīng)驗(yàn)表明,中、低壓電力電纜故障大部分為電纜中間接頭和終端頭故障,而中間接頭和終端頭故障則大部分是因密封不良,潮氣侵入而造成絕緣強(qiáng)度下降,而中、低壓電力電纜網(wǎng)多采用樹(shù)枝狀供電方式,電纜終端頭數(shù)量較多,因此把好電纜終端頭和中間接頭堵漏密封關(guān)是保證電纜安全可靠運(yùn)行的重要措施之一。在公用中、低壓電力電纜網(wǎng)上,由于三相負(fù)荷不是相等的,因此,如果采用有金屬護(hù)層的電纜,必須考慮金屬護(hù)層的接地問(wèn)題,并保證在金屬護(hù)層的任一點(diǎn)非接地處的正常感應(yīng)電壓不得大于100V。我認(rèn)為,在中、低壓電纜網(wǎng)中,所有電纜接頭處均應(yīng)設(shè)置接地極(網(wǎng)),并使金屬護(hù)層可靠接地。

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。
