對(duì)每一種電流互感器，二次開路電壓隨著一次電流的變化，都有嚴(yán)格的對(duì)應(yīng)關(guān)系，*以一次額定電流時(shí)的二次開路電壓值說(shuō)明。對(duì)母線穿心式150／5的電流互感器，當(dāng)穿心電流為額定值時(shí)，不同品種的電流互感器二次開路電壓為2．6～2；4V。80條二次開路電壓特性曲線的規(guī)律是：一次穿心電流從0A增至150A時(shí)，二次開路電壓開始上升幅度很大，30A以后增加甚小(即使從150A增至800A，二次開路電壓平均只上升0．2V)。 </p> <p> 母線穿心式200/5的電流互感器，二次開路電壓是3．9～6．5V；母線穿心式 300／5—2000／5的電流互感器，二次開路電壓為6．5～37．2V。 </p> <p> LQG系列從30／5—600／5的電流互感器，二次開路電壓是12．8～21．4V。 </p> <p> 變電站用的LQJ，LFC，LFCD系列50／5～300／5的電流互感器，二次開路電壓是18～121．3V。

在第二次伏安特實(shí)驗(yàn)臺(tái)上，利用調(diào)壓器、電流表、導(dǎo)線將所有的電流互感器二次線圈分別接人調(diào)壓器的輸出端，當(dāng)二次輸入5A電流時(shí)，測(cè)得二次電壓和一次加額定電流時(shí)測(cè)得的二次開路電壓都有嚴(yán)格的對(duì)應(yīng)關(guān)系。若用公式計(jì)算，二次開路電壓等于二次閉路轉(zhuǎn)為開路一次電壓的增量乘以變化。從正反兩方面實(shí)驗(yàn)和法拉第電磁感應(yīng)定律推導(dǎo)結(jié)論證明了二次開路電壓測(cè)試值的真實(shí)性 </p><p> 電氣調(diào)試是電力工作中一項(xiàng)重要的內(nèi)容，在電氣調(diào)試工作中，二次回路檢查又是一項(xiàng)重要的調(diào)試內(nèi)容，它是關(guān)系到電力系統(tǒng)的測(cè)量、保護(hù)、通訊等功能能否發(fā)揮作用的前提。在二次回路中，電流互感器的接線是否正確又是電流二次回路是否正確的基礎(chǔ)，所以電流互感器的接線正確性非常重要。很多電氣調(diào)試人員對(duì)它沒(méi)有深刻的理解，經(jīng)常搞錯(cuò)，造成諸如差動(dòng)保護(hù)誤動(dòng)作、電度表反轉(zhuǎn)等。下面對(duì)這個(gè)問(wèn)題做一個(gè)***、細(xì)致的論述。電氣調(diào)試是電力工作中一項(xiàng)重要的內(nèi)容，在電氣調(diào)試工作中，二次回路檢查又是一項(xiàng)重要的調(diào)試內(nèi)容，它是關(guān)系到電力系統(tǒng)的測(cè)量、保護(hù)、通訊等功能能否發(fā)揮作用的前提。在二次回路中，電流互感器的接線是否正確又是電流二次回路是否正確的基礎(chǔ)，所以電流互感器的接線正確性非常重要。很多電氣調(diào)試人員對(duì)它沒(méi)有深刻的理解，經(jīng)常搞錯(cuò)，造成諸如差動(dòng)保護(hù)誤動(dòng)作、電度表反轉(zhuǎn)等。下面對(duì)這個(gè)問(wèn)題做一個(gè)***、細(xì)致的論述。電流互感器的結(jié)構(gòu)較為簡(jiǎn)單，由相互絕緣的一次繞組、二次繞組、鐵心以及構(gòu)架、殼體、接線端子等組成。其工作原理與變壓器基本相同，一次繞組的匝數(shù)(N1)較少，直接串聯(lián)于電源線路中，一次負(fù)荷電流。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

上海喆和發(fā)現(xiàn)，目前生產(chǎn)和應(yīng)用的電流互感器的發(fā)熱特性與傳統(tǒng)結(jié)論截然不同：其二次開路狀態(tài)工作時(shí)，一般不會(huì)過(guò)熱；只有極少數(shù)型號(hào)功耗增大，發(fā)熱嚴(yán)重，但在正常工作電流下，也不會(huì)燒壞設(shè)備。至于二次開路電壓，則始終在低壓范圍內(nèi)波動(dòng)。上海喆和在對(duì)數(shù)十種型號(hào)的電流互感器進(jìn)行實(shí)驗(yàn)測(cè)定的基礎(chǔ)上，得出結(jié)論，二次開路時(shí)具有恒壓源和恒流源兩種電路的特性，可以穩(wěn)定、可靠地用作自動(dòng)控制功率型信號(hào)源。這種突破傳統(tǒng)的電路運(yùn)用方式，可廣泛應(yīng)用于自動(dòng)化控制設(shè)計(jì)，產(chǎn)生良好的經(jīng)濟(jì)效益和社會(huì)效益。
