為什么<strong>電壓</strong><strong>互感器</strong>不能短路，電流互感器不得開(kāi)路？（三） </p> <p> 電壓互感器正常運(yùn)行過(guò)程中，電壓互感器工作接近空載狀態(tài)，而且二次側(cè)的負(fù)荷阻抗也很大，因此二次回路中流過(guò)的電流不是很大，于是在額定輸出條件下，設(shè)備運(yùn)行是很安全的。 </p> <p> 倘若此時(shí)電壓互感器二次側(cè)短路，此刻二次側(cè)負(fù)荷阻抗幾乎為零，不起作用了。短路電流**流過(guò)電壓互感器自身繞組，又加上自身繞組阻抗也很小，于是電流急劇增加。 </p> <p> 這對(duì)容量不大、一二次繞組導(dǎo)線較細(xì)的電壓互感器來(lái)說(shuō)非常危險(xiǎn)，嚴(yán)重時(shí)可能導(dǎo)致電壓互感器燒壞甚至。 </p><p> 8、<strong>電壓互感器</strong>的典型缺陷及處理方法（一） </p> <p> （1）密封件滲漏油：一般先檢查緊固螺栓是否緊固，調(diào)整密封件，或者更換老化的密封件。 </p> <p> （2）材質(zhì)不良和焊縫滲漏油：一般采用堵漏膠堵漏或電焊的方法，電焊后必須更換絕緣油。 </p> <p> （3）二次小套管滲漏油：打開(kāi)底板擰緊滲漏油套管的壓緊螺母，或輕輕松開(kāi)壓緊螺母，取下螺母及平墊，在螺桿上纏生膠帶并涂密封膏，然后再用平墊、螺母將其壓緊，以防沿螺牙滲漏油。滲漏油嚴(yán)重的應(yīng)更換套管。 </p> <p> （4）末屏接地裝置放電：這主要是末屏接地未接好，因此在安裝時(shí)的多次驗(yàn)收試驗(yàn)后必須認(rèn)真檢查末屏接地情況，在運(yùn)行、試驗(yàn)后切勿忘記末屏接地。了解電流互感器型號(hào),正確選擇電流互感器！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

油浸式電壓互感器按其結(jié)構(gòu)可分為普通式和串級(jí)式，3～35kV都制成普通式，它與普通小型變壓器相似。110kV及以上的電磁式電壓互感器普遍制成串級(jí)結(jié)構(gòu)，其特點(diǎn)是：繞組和鐵芯采用分級(jí)絕緣，以簡(jiǎn)化絕緣結(jié)構(gòu)；繞組和鐵芯放在瓷套中，可減少重量和體積。 </p> <p> 電壓互感器的基本結(jié)構(gòu)和變壓器很相似，它也有兩個(gè)繞組，一個(gè)叫一次繞組，一個(gè)叫二次繞組。兩個(gè)繞組都裝在或繞在鐵心上。兩個(gè)繞組之間以及繞組與鐵心之間都有絕緣，使兩個(gè)繞組之間以及繞組與鐵心之間都有電的隔離。電壓互感器在運(yùn)行時(shí)，一次繞組N1并聯(lián)接在線路上，二次繞組N2并聯(lián)接儀表或繼電器。因此在測(cè)量高壓線路上的電壓時(shí)，盡管一次電壓很高，但二次卻是低壓的，可以確保操作人員和儀表的安全。 </p> <p> 電壓互感器的線圈阻抗較小，所以電壓互感器的二次繞組不能短路，二次繞組如果短路將導(dǎo)致繞組承受的阻抗變大，繞組承受不了造成PT燒毀。行程電流互感器的快速調(diào)整方法。通用電壓互感器商家</p><p style="text-indent:25px">電流互感器的故障原因分析處理方法。通用電壓互感器現(xiàn)價(jià)</p><p
