延長使用期限。雙色水位計雙色水位計主要有透射式、反射式和反透式等數(shù)種。透射式雙色水位計這種水位計由反光鏡、光原、紅、綠濾光鏡、柱面聚鏡、平面鏡、影屏、框架、汽水旋塞等構(gòu)件組成。透射式雙色水位計的工作原理與其他形式的水位計基本相同，所不同的是光源的光線經(jīng)反光鏡反射，通過光學(xué)系統(tǒng)，使穿過水的那部分光線在影屏鏡上呈綠色，而穿過汽的那部分光線在影屏鏡上呈紅色，從而在影屏鏡上顯示了代表水綠、汽紅鍋筒內(nèi)水位的變化。反射式雙色水位計反射式雙色水位計是利用光在水和蒸汽中具有不同的折射率，通過棱鏡的反射作用，使水位計中蒸汽部分呈紅色．水部分呈綠色。反透式雙色水位計它的結(jié)構(gòu)介于透射式與反射式之間，其水位顯示既利用了光線的透射。

可以調(diào)節(jié)升流器電流的調(diào)壓器，及負(fù)載。[10]注意事項電流互感器-使用注意事項電流互感器[11]運(yùn)行時，副邊不允許開路。因為一旦開路，原邊電流均成為勵磁電流，使磁通和副邊電壓大大超過正常值而危及人身和設(shè)備。因此，電流互感器副邊回路中不許接熔斷器，也不允許在運(yùn)行時未經(jīng)旁路就拆下電流表、繼電器等設(shè)備。電流互感器運(yùn)行時，副邊不允許開路。原因如下：⒈電流互感器一次被測電流磁勢I1N1在鐵芯產(chǎn)生磁通Φ1⒉電流互感器二次測量儀表電流磁勢I2N2在鐵芯產(chǎn)生磁通Φ2⒊電流互感器鐵芯合磁通：Φ=Φ1+Φ2⒋因為Φ1.Φ2方向相反，大小相等，互相抵消，所以Φ=0⒌若二次開路，即I2=0，則：Φ=Φ1，電流互感器鐵芯磁通很強(qiáng)。

同時由于起動轉(zhuǎn)矩較大，將對負(fù)載產(chǎn)生沖擊，增加傳動部件的磨損和額外維護(hù)。所以當(dāng)電機(jī)的容量較大（一般為超過電源容量的20%—30%時）均采用降壓起動。傳統(tǒng)上采用的降壓起動的方法有Y/△換接起動和自耦變壓器降壓起動。雖然這兩種起動方式均可降低起動電流，但是在降壓起動過程完成后的分檔投切和加全壓的瞬間，仍將產(chǎn)生數(shù)倍額定電流的尖峰電流（二次沖擊電流），此電流將對配電系統(tǒng)造成沖擊，同時產(chǎn)生的破壞性的動態(tài)轉(zhuǎn)矩會引起水泵電機(jī)的機(jī)械震動，對電機(jī)的轉(zhuǎn)子、中間齒輪等非常有害，并使供電線路電耗增大。軟啟動器也是降壓起動器的一種。它是利用性能先進(jìn)的微處理器，合理有序地控制大功率晶閘管組件導(dǎo)通，使之產(chǎn)生逐步增加的平滑的交流電壓加在交流電動機(jī)上。
