?10kV配電線高壓與低壓問題，顧名思義就是在標(biāo)準(zhǔn)電壓情況下，由于某種原因造成10kV配電線網(wǎng)內(nèi)部的線路電壓呈現(xiàn)一種不穩(wěn)定的情況，而通常這種不穩(wěn)定情況往往伴隨著電壓的劇烈變化，進(jìn)而造成監(jiān)控10kV配電線的電壓器數(shù)據(jù)偏高或是偏低，給人們的人身安全和各種安全事故埋下了巨大隱患。一般造成10kV配電線高壓與低壓問題的原因分為兩種，包括人為原因和外界干擾原因。人為原因很簡單就是在配電線網(wǎng)正常運(yùn)行，技術(shù)人員進(jìn)行錯(cuò)誤的流程操作或是輸入錯(cuò)誤的數(shù)據(jù)信息，從而造成線網(wǎng)短時(shí)間內(nèi)被破壞，出現(xiàn)高電壓或是低電壓現(xiàn)象，配電線網(wǎng)運(yùn)行系統(tǒng)癱瘓；相對可控制的人為原因，外界干擾因素則是令供電部門十分苦惱，尤其是在豐水季節(jié)，大量降雨、雷電和潮濕環(huán)境都會(huì)對10kV配電線網(wǎng)造成一定損壞和侵蝕，運(yùn)行系統(tǒng)不穩(wěn)定，配電線網(wǎng)中的電壓也不穩(wěn)定，兩者運(yùn)行一直呈現(xiàn)惡性循環(huán)，縮短用電設(shè)備的使用壽命，增加用電的危險(xiǎn)性。隨著技術(shù)人員自身專業(yè)水平的提高，造成10kV配電線高壓與低壓問題的主要原因還是外界因素干擾，但不論是哪種原因造成高電壓和低電壓問題，最根本的因素還是10kV配電線高壓與低壓調(diào)節(jié)技術(shù)，則如何在配電線網(wǎng)被破壞或是被干擾的情況下，調(diào)節(jié)10kV配電線網(wǎng)整體電壓處于正常電壓狀態(tài)下，成為解決10kV配電線高壓與低壓問題的主要措施。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。
