根據(jù)上文對10kV配電線高壓與低壓問題的分析，可以知道造成高電壓和低電壓問題的根本因素是電壓調(diào)節(jié)因素，因此，供電部門往往會(huì)采用以往的經(jīng)驗(yàn)進(jìn)行電壓調(diào)節(jié)，例如：并聯(lián)配電線網(wǎng)整體電容和電壓調(diào)節(jié)器，進(jìn)而控制配電線網(wǎng)電壓范圍，再者就是并聯(lián)電抗器和電壓調(diào)節(jié)器，同樣也能控制配電線網(wǎng)電壓范圍。雖然采用以往經(jīng)驗(yàn)也能有效的解決10kV配電線高壓與低壓問題，但在實(shí)際建設(shè)和操作中存在著眾多問題，以文中并聯(lián)電抗器和電壓調(diào)節(jié)器為例子，首先電壓調(diào)節(jié)器的頻繁使用會(huì)對配電線網(wǎng)造成一定的損傷，而且在一定情況下，電壓調(diào)節(jié)器不僅不能使用還會(huì)阻礙電抗器的正常使用，進(jìn)而造成配電線網(wǎng)長時(shí)間處于超負(fù)荷狀態(tài)，進(jìn)而增加高電壓和低電壓問題出現(xiàn)的頻率。因此，為確保配電線網(wǎng)的正常運(yùn)行，一般供電部門用串聯(lián)補(bǔ)償技術(shù)代替一般的電壓調(diào)節(jié)措施。串聯(lián)補(bǔ)償技術(shù)原理和一般的電壓調(diào)節(jié)措施原理是一致的，就是利用各種設(shè)備和線路對配電線網(wǎng)電壓進(jìn)行調(diào)節(jié)。根據(jù)大量實(shí)驗(yàn)所得出的電壓補(bǔ)償量與配電線網(wǎng)所承載的電流成正比，串聯(lián)補(bǔ)償將把電容器線路進(jìn)行串聯(lián)被設(shè)置相關(guān)的電壓電流監(jiān)控設(shè)備，減少配電線網(wǎng)中有效的電抗，或是由于線路材料問題造成的電阻，造成配電線網(wǎng)首尾之間存在一定的電壓補(bǔ)償量，延長對瞬間錯(cuò)誤信息的傳遞，使得配電線網(wǎng)內(nèi)部設(shè)備可以對高電壓和低電壓信息進(jìn)行正確處理，提升配電線網(wǎng)整體的供電能力。綜上所述，可以知道串聯(lián)補(bǔ)償技術(shù)原理其實(shí)就是控制配電線網(wǎng)中線路負(fù)荷量，有效的降低電壓補(bǔ)償量，從而減少電流補(bǔ)償問題的出現(xiàn)，解決10kV配電線高壓與低壓問題。電容器保護(hù)。電容器是由兩個(gè)電極及其間的介電材料構(gòu)成的，主要發(fā)揮著儲(chǔ)存電能和轉(zhuǎn)換電能的作用，即其自身會(huì)自動(dòng)以另一種狀態(tài)儲(chǔ)存10kV配電線網(wǎng)中多余的電能，在10kV配電線網(wǎng)中缺少電能時(shí)，自動(dòng)將自身儲(chǔ)存電能轉(zhuǎn)化成配電網(wǎng)可以使用的電能，以能夠支持配電線網(wǎng)內(nèi)部的正常使用和運(yùn)作。針對電容器發(fā)揮的作用，串聯(lián)補(bǔ)償技術(shù)主要是通過避免電容器出現(xiàn)過負(fù)荷和不平衡現(xiàn)象來對電容器進(jìn)行保護(hù)，在各個(gè)10kV配電線網(wǎng)中設(shè)置電壓和電流監(jiān)控系統(tǒng)，并定期對電壓電流數(shù)值與正常數(shù)值進(jìn)行比對，一旦發(fā)現(xiàn)高電壓或是低電壓現(xiàn)象，便立即拉起危險(xiǎn)警報(bào)提醒相關(guān)工作人員進(jìn)行檢查。MOV保護(hù)。串聯(lián)補(bǔ)償技術(shù)對MOV保護(hù)分為四部分：過電流保護(hù)、能量保護(hù)、溫度保護(hù)和不平衡保護(hù)，過電流保護(hù)和不平衡保護(hù)原理同上文對電容器保護(hù)是相同的，都是在配電線網(wǎng)中加入監(jiān)控設(shè)備，并依據(jù)監(jiān)控設(shè)備內(nèi)部相關(guān)數(shù)據(jù)信息和標(biāo)準(zhǔn)信息比對結(jié)果，再?zèng)Q定下一步流程操作是否繼續(xù)；相對于以上設(shè)備對故障穩(wěn)定發(fā)現(xiàn)的及時(shí)性，能量保護(hù)和溫度保護(hù)發(fā)現(xiàn)故障問題的速度就會(huì)慢一些，因?yàn)槠涫遣捎梅e分曲線的形式，對一段時(shí)間內(nèi)部的MOV電流積分和定值進(jìn)行比較。
