防止水垢形成。由于鈣鎂等離子從水中析出，水便回復(fù)于高溶解狀態(tài)，水本身為高溶解度，但會因吸收其它而致飽和，當(dāng)回復(fù)為高溶解狀態(tài)的水流經(jīng)有水垢的管道，便能把水垢溶解并吸收，并于排水時排走，因此，該產(chǎn)品除具有防止水垢形成外，還能有效老垢。日常檢查與編輯日常檢查冷卻器投用后,操作人員應(yīng)定期對換熱器進行巡回檢查,判斷其是否運行正常。(1)檢查工藝參數(shù)，嚴禁超溫、超壓運行。(2)檢查隔槽、大鍋、接口法蘭有無泄漏。(3)檢查基礎(chǔ)支座的穩(wěn)固情況。(4)檢查冷卻器及管線的振動情況。(5)定時查看油品顏色及換熱后的溫度變化。日常冷卻器因冷卻水大多數(shù)含有鈣、鎂離子和酸式碳酸鹽。當(dāng)冷卻水流經(jīng)金屬表面時。

使兩個繞組之間以及繞組與鐵心之間都有電氣隔離。電壓互感器在運行時，一次繞組N1并聯(lián)接在線路上，二次繞組N2并聯(lián)接儀表或繼電器。因此在測量高壓線路上的電壓時，盡管一次電壓很高，但二次卻是低壓的，可以確保操作人員和儀表的。工作原理編輯其工作原理與變壓器相同[2]，基本結(jié)構(gòu)也是鐵心和原、副繞組。特點是容量很小且比較恒定，正常運行時接近于空載狀態(tài)。電壓互感器本身的阻抗很小，一旦副邊發(fā)生短路，電流將急劇增長而燒毀線圈。為此，電壓互感器的原邊接有熔斷器，副邊可靠接地，以免原、副邊絕緣損毀時，副邊出現(xiàn)對地高電位而造身和設(shè)備事故。測量用電壓互感器一般都做成單相雙線圈結(jié)構(gòu)，其原邊電壓為被測電壓（如電力的線電壓）。要直接制作高壓儀表，直接在高壓線路上測量電壓，那是不可能的，而且也是不允許的。主要類型編輯按安裝可分為戶內(nèi)式和戶外式[4]35kV及以下多制成戶內(nèi)式；35kV以上則制成戶外式。按相數(shù)可分為單相和三相式35kV及以上不能制成三相式。按繞組數(shù)目可分為雙繞組和三繞組電壓互感器，三繞組電壓互感器除一次側(cè)和基本二次側(cè)外，還有一組輔助二次側(cè)，供接地保護用。按絕緣可分為干式、澆注式、油浸式和充氣式[1]。干式電壓互感器結(jié)構(gòu)簡單、無著火和危險，但絕緣強度較低，只適用于6kV以下的戶內(nèi)式裝置；澆注式電壓互感器結(jié)構(gòu)緊湊、方便，適用于3kV～35kV戶內(nèi)式配電裝置；油浸式電壓互感器絕緣性能。
3、壓力使用，在實際需要的壓力段運行，據(jù)統(tǒng)計每下降1公斤壓力可節(jié)能大約7%的能耗。

軟啟動器只是改變電源電壓，相當(dāng)于降壓起動器。變頻器要比軟啟動器復(fù)雜得多，價格也貴得多。變頻器也有軟啟動功能，是通過改變電源實現(xiàn)。高壓啟動器和低壓啟動器的區(qū)別軟啟動器主回路采用晶閘管，通過逐步改變晶閘管的導(dǎo)通角來抬升電壓，完成啟動，這是軟啟動器的基本原理。在低壓軟啟動器市場，產(chǎn)品繁多，但是高壓軟啟動器產(chǎn)品還是比較少。高壓軟啟動器與低壓軟啟動器基本原理一樣，但是高壓軟啟動器與低壓軟啟動器相比，有些地方存在著其特殊性：高壓軟啟動器在高壓下工作，各種電氣元器件的絕緣性能一定要好，電子芯片的抗能力要強。高壓軟起動器組成電氣柜時，電氣元器件的布局以及與高壓軟啟動器與其它電氣設(shè)備的連接也是非常重要的。造成鐵心飽和磁化，嚴重乃至燒毀線圈；同時，磁路飽和磁化后，使誤差增大。電流互感器在正常工作時，二次側(cè)與測量儀表和繼電器等電流線圈串聯(lián)使用，測量儀表和繼電器等電流線圈阻抗很小，二次側(cè)近似于短路。CT二次電流的大小由一次電流決定，二次電生的磁勢，是平衡一次電流的磁勢的。若突然使其開路，則勵磁電動勢由數(shù)值很小的值驟變?yōu)楹艽蟮闹?，鐵芯中的磁通呈現(xiàn)嚴重飽和的平頂波，因此二次側(cè)繞組將在磁通過零時感應(yīng)出很高的尖頂波，其值可達到數(shù)千甚至上萬伏，危及工作人員的及儀表的絕緣性能。另外，二次側(cè)開路使二次側(cè)電壓達幾百伏，一旦觸及將造成觸電事故。因此，電流互感器二次側(cè)都備有短路開關(guān)，防止二次側(cè)開路。在使用中。
