2．6儀表采用LCD液晶顯示,大方直觀。儀表上排常顯總電量數(shù)據(jù)，下排輪顯常數(shù)，表號(hào)，電壓，電流，功率，功率因數(shù)，頻率數(shù)據(jù)，每項(xiàng)數(shù)據(jù)輪顯時(shí)間為5秒。</p><p style="text-indent:25px">目前國(guó)內(nèi)市場(chǎng)上被宣傳 SVC的產(chǎn)品主工是晶閘管控制電抗器（TCR）和晶閘管投切電容器（TSC）。對(duì)于TSC我們另文敘述，這里只簡(jiǎn)要介紹一下晶閘管控制電抗器（TCR）。 TCR的基本結(jié)構(gòu)包括一組固定并聯(lián)連接在線路中的電容器和一組并聯(lián)連接在線路中用晶閘管控制的電抗器，通常將電抗器的容量設(shè)計(jì)成與電容器一樣。由于電抗器是用晶閘管控制的，其感性無(wú)功電流可以變化，當(dāng)晶閘管關(guān)斷時(shí)，電抗器沒有電流，而電容器固定連接，因此整套裝置的補(bǔ)償量比較大，當(dāng)調(diào)節(jié)晶閘管的導(dǎo)通角時(shí)，電抗器的感性電流就會(huì)抵消一部分電容器電流，因此補(bǔ)償量減少，導(dǎo)通角越大，電抗器的電流越大，補(bǔ)償量就越小，當(dāng)晶閘管全通時(shí)，電抗器電流就會(huì)將電容器電流全部抵消，此時(shí)補(bǔ)償量為0。必須將固定電容器組設(shè)計(jì)成濾波器形式或者配備另外的濾波器。綜上所述，可以看出TCR的結(jié)構(gòu)復(fù)雜，損耗大，但其具有補(bǔ)償量連續(xù)可調(diào)的特點(diǎn)，在高壓系統(tǒng)中還有應(yīng)用。</p><div

在正常情況下，用電設(shè)備不但要從電源取得有功功率，同時(shí)還需要從電源取得無(wú)功功率。如果電網(wǎng)中的無(wú)功功率供不應(yīng)求，用電設(shè)備就沒有足夠的無(wú)功功率來建立正常的電磁場(chǎng)，這些用電設(shè)備就不能維持在額定情況下工作，用電設(shè)備的端電壓就要下降，從而影響用電設(shè)備的正常運(yùn)行。但是從發(fā)電機(jī)和高壓輸電線供給的無(wú)功功率遠(yuǎn)遠(yuǎn)滿足不了負(fù)荷的需要，所以在電網(wǎng)中要設(shè)置一些無(wú)功補(bǔ)償裝置來補(bǔ)充無(wú)功功率，以保證用戶對(duì)無(wú)功功率的需要，這樣用電設(shè)備才能在額定電壓下工作。無(wú)功補(bǔ)償是把具有容性功率負(fù)荷的裝置與感性功率負(fù)荷并聯(lián)接在同一電路，能量在兩種負(fù)荷之間相互交換，這樣，感性負(fù)荷所需要的無(wú)功功率可由容性負(fù)荷輸出的無(wú)功功率補(bǔ)償。河南載波電表生產(chǎn)</p><p
