真空斷路器在真空泡內(nèi)開斷電流并進(jìn)行滅弧，而真空斷路器本身沒有定性、定量監(jiān)測真空度特性的裝置，所以真空度降低故障為隱性故障，其危險(xiǎn)程度遠(yuǎn)遠(yuǎn)大于顯性故障。真空度降低將嚴(yán)重影響真空斷路器開斷過電流的能力，并導(dǎo)致斷路器的使用壽命急劇下降，嚴(yán)重時(shí)會(huì)引起開關(guān)。在進(jìn)行斷路器定期停電檢修時(shí)，需要使用真空測試儀對真空泡進(jìn)行真空度的定性測試，確保真空泡具有一定的真空度；當(dāng)真空度降低時(shí)，需要更換真空泡，并做好行程、同期、彈跳等特性試驗(yàn)。

合閘彈跳時(shí)間是斷路器在合閘時(shí)，觸頭剛接觸開始計(jì)起，隨后產(chǎn)生分離，可能又接觸又分離，到其穩(wěn)定接觸之間的時(shí)間。這一參數(shù)國外的標(biāo)準(zhǔn)中都沒有明確規(guī)定，1989年底能源部電力司提出真空斷路器合閘彈跳時(shí)間需要小于2ms。為什么合閘彈跳時(shí)間要小于2ms呢？主要是合閘彈跳的瞬間會(huì)引起電力系統(tǒng)或設(shè)備產(chǎn)生L.C高頻振蕩，振蕩產(chǎn)生的過電壓對電氣設(shè)備的絕緣可能造成傷害甚至損壞。當(dāng)合閘彈跳時(shí)；同小于2ms時(shí)，不會(huì)產(chǎn)生較大的過電壓，設(shè)備絕緣不會(huì)受損，在關(guān)合時(shí)動(dòng)靜觸頭之間也不會(huì)產(chǎn)生熔焊。

style="text-indent:25px">斷路器有哪一些特性？北京斷路器廠家</p><p> 斷路器通常由觸頭系統(tǒng)、滅弧系統(tǒng)、操作機(jī)構(gòu)、脫扣器、外殼等組成。當(dāng)短路時(shí)，大電流（一般10至12倍）產(chǎn)生的磁場克服反力彈簧，脫扣器拉動(dòng)操作機(jī)構(gòu)動(dòng)作，開關(guān)瞬時(shí)跳閘。當(dāng)過載時(shí)，電流變大，發(fā)熱量加劇，雙金屬片變形到一定程度推動(dòng)機(jī)構(gòu)動(dòng)作（電流越大，動(dòng)作時(shí)間越短）。有電子型的，運(yùn)用互感器采集各相電流大小，與設(shè)定值比較，當(dāng)電流異常時(shí)微處理器發(fā)出信號，使電子脫扣器帶動(dòng)操作機(jī)構(gòu)動(dòng)作。斷路器的作用是切斷和接通負(fù)荷電路，以及切斷故障電路，避免***擴(kuò)大，保證可靠運(yùn)行。而高壓斷路器要開斷1500V，電流為1500-2000A的電弧，這些電弧可拉長至2m仍然繼續(xù)燃燒不熄滅。故滅弧是高壓斷路器許需要解決的問題。
