（1）二次電壓波動(dòng)。二次連接松動(dòng)，分壓器低壓端子未接地或未接載波線圈；如果阻尼器是速飽和電抗器，則有可能是參數(shù)配合不當(dāng)。 </p> <p> （2）二次電壓低。二次連接不良，電磁單元故障或電容單元C2損壞。 </p> <p> （3）二次電壓高。電容單元C1損壞，分壓電容接地端未接地。 </p> <p> （4）電磁單元油位過高。下節(jié)電容單元漏油或電磁單元進(jìn)水。 </p> <p> （5）投運(yùn)時(shí)有異音。電磁單元中電抗器或中壓變阻器螺栓松動(dòng)。 </p> <p> CVT等效電路模型 </p> <p>

因此電力系統(tǒng)中通過CVT測(cè)量得到的諧波數(shù)據(jù)已經(jīng)是如上述頻率特性曲線畸變后的結(jié)果，不能真實(shí)地反映一次側(cè)系統(tǒng)諧波情況。在110kV及以上電網(wǎng)現(xiàn)場(chǎng)大量使用CVT的情況下，諧波電壓的測(cè)量準(zhǔn)確性問題函待解決，針對(duì)此問題以下兒點(diǎn)改進(jìn)方法建議以供參考。 </p> <p> 1)現(xiàn)場(chǎng)條件允許時(shí)，應(yīng)采用電容式分壓器測(cè)量諧波電壓。對(duì)已裝設(shè)電容分壓器的現(xiàn)場(chǎng)應(yīng)使用電容分壓器測(cè)量，如沒有裝設(shè)且需對(duì)諧波電壓情況詳細(xì)了解的測(cè)試點(diǎn)應(yīng)臨時(shí)裝設(shè)電容分壓器再進(jìn)行測(cè)量。 </p> <p> 2)在CVT的高低壓電容接地回路接入兩個(gè)電流傳感器，可測(cè)得CVT高低壓側(cè)電容回路的電流，分別計(jì)算兩個(gè)電容器的壓降，向量迭加后可得CVT對(duì)應(yīng)頻率下一次側(cè)電壓值?，F(xiàn)有基于該原理的裝置有ABB公司的PQSensor等，使用該裝置在150kV某CVT上模擬試驗(yàn)，與并聯(lián)的電磁式電壓互感器比較，結(jié)果具有較好的一致性，此設(shè)備可安裝在已投運(yùn)的CVT上，不影響CVT原有性能。電流互感器的如何選擇呢?臺(tái)州電壓互感器企業(yè)</p><p style="text-indent:25px">電流互感器的的圖形和文字符號(hào)怎么看?臺(tái)州電壓互感器企業(yè)</p><p> <strong>電壓互感器</strong>的基本結(jié)構(gòu) </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氣隔離。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。主要是用來給測(cè)量?jī)x表和繼電保護(hù)裝置供電，用來測(cè)量線路的電壓、功率和電能，或者用來在線路發(fā)生故障時(shí)保護(hù)線路中的貴重設(shè)備、電機(jī)和變壓器。臺(tái)州電壓互感器企業(yè)</p><p
