1.多油斷路器:利用絕緣油作為滅弧介質(zhì)、相間及相對地絕緣介質(zhì)。
2.少油斷路器:絕緣油只作滅弧介質(zhì)。載流部分是借空氣和陶器絕緣材料或有機(jī)絕緣材料來絕緣,滅弧方式多為橫向吹動電弧。
3.空氣斷路器:利用壓縮空氣的吹動來熄滅電弧的。和控制斷路器的分合闡動作。
4.SF6斷路器:用SF6氣體作絕緣和滅弧介質(zhì)。
5.磁吹式斷路器:當(dāng)電弧電流通過吹弧線圈以產(chǎn)生磁束來吹弧及消弧。
6.真空斷路器:利用真空滅弧和絕緣,滅弧時(shí)間一般只有半個(gè)周波。
10.2 斷路器的主要性能與參數(shù)
1.額定電壓及額定電流
(1)額定電壓
指斷路器長期工作的標(biāo)準(zhǔn)電壓(對三相系統(tǒng)指線電壓)。電力系統(tǒng)在運(yùn)行中允許有±5%的波動,斷路器必須適應(yīng)在電壓變化范圍內(nèi)能長期工作,為此斷路器出廠時(shí)都以高工作電壓進(jìn)行鑒定。如:對3~220kV范圍內(nèi),其高工作電壓較額定電壓約高15%左右;對330kV以上,規(guī)定高工作電壓較額定電壓高10%。
2)額定電流
指在額定頻率下長期通過此電流時(shí),斷路器無損傷,且各部分發(fā)熱不超過長期工作時(shí)高允許發(fā)熱溫度。
我國規(guī)定額定電流為:200、400、630、(1000)、1250、1600、(1500)、2000、3150、4000、5000、6300、8000、10000、12500、16000、20000A。
額定開斷電流和額定斷流容量
(1)斷路器在開斷操作時(shí),首先起弧的某相電流稱為開斷電流。在額定電壓下,能保證正常開斷的大短路電流稱為額定開斷電流。它是標(biāo)志斷路器開斷能力的一個(gè)重要參數(shù)。
我國規(guī)定額定開斷電流為:1.6、3.15、6.3、8、10、12.5、16、20、25、31.5、40、50、63、80、100kA等。
