NABXZ Series Automatic frequency resonant test system NABXZ全自動(dòng)變頻串聯(lián)諧振耐壓試驗(yàn)成套裝置
產(chǎn)品簡(jiǎn)介
NABXZ系列全自動(dòng)變頻串聯(lián)諧振高壓試驗(yàn)裝置,主要針對(duì)10kV、35kV、110kV、220kV、變電站及線路等所有電氣主設(shè)備的交流耐壓試驗(yàn)設(shè)計(jì)制造。電抗器采用多只分開設(shè)計(jì),既可滿足高電壓、小電流的設(shè)備試驗(yàn)條件要求,又能滿足低電壓的交流耐壓試驗(yàn)要求,具有較寬的適用范圍,是地、市、縣級(jí)高壓試驗(yàn)部門及電力安裝、修試工程單位理想的耐壓設(shè)備。
產(chǎn)品別名
變頻諧振,變頻串聯(lián)諧振,串聯(lián)諧振,串聯(lián)諧振變壓器,串聯(lián)諧振試驗(yàn)設(shè)備,便攜式電纜耐壓試驗(yàn)裝置,工頻串聯(lián)諧振試驗(yàn)設(shè)備,串聯(lián)諧振系統(tǒng)
產(chǎn)品特性
1、所需電源容量大大減小。串聯(lián)諧振電源是利用諧振電抗器和被試品電容諧振產(chǎn)生高電壓和大電流的,在整個(gè)系統(tǒng)中,電源只需要提供系統(tǒng)中有功消耗的部分,因此,試驗(yàn)所需的電源功率只有試驗(yàn)容量的1/Q。
2、設(shè)備的重量和體積大大減少。串聯(lián)諧振電源中,不但省去了笨重的大功率調(diào)壓儀器和普通的大功率工頻試驗(yàn)變壓器,而且諧振激磁電源只需試驗(yàn)容量的1/Q,使得系統(tǒng)重量和體積大大減少,一般為普通試驗(yàn)儀器的1/10-1/30。
3、改善輸出電壓的波形。諧振電源是諧振式濾波電路,能改善輸出電壓的波形畸變,獲得很好的正弦波形,有效的防止了諧波峰值對(duì)試品的誤擊穿。
4、防止大的短路電流燒傷故障點(diǎn)。在串聯(lián)諧振狀態(tài),當(dāng)試品的絕緣弱點(diǎn)被擊穿時(shí),電路立即脫諧,回路電流迅速下降為正常試驗(yàn)電流的1/Q。而并聯(lián)諧振或者試驗(yàn)變壓器方式做耐壓試驗(yàn)時(shí),擊穿電流立即上升幾十倍,兩者相比,短路電流與擊穿電流相差數(shù)百倍。所以,串聯(lián)諧振能有效的找到絕緣弱點(diǎn),又不存在大的短路電流燒傷故障點(diǎn)的憂患。
5、不會(huì)出現(xiàn)任何恢復(fù)過(guò)電壓。試品發(fā)生擊穿時(shí),因失去諧振條件,高電壓也立即消失,電弧即刻熄滅,且恢復(fù)電壓的再建立過(guò)程很長(zhǎng),很容易在再次達(dá)到閃絡(luò)電壓前斷開電源,這種電壓的恢復(fù)過(guò)程是一種能量積累的間歇振蕩過(guò)程,其過(guò)程長(zhǎng),且不會(huì)出現(xiàn)任何恢復(fù)過(guò)電壓。
