1、隔離開關(guān)的作用是斷開無負(fù)荷電流的電路.使所維修的設(shè)備與電源有顯著的斷開點，以確保維修人員的安全，阻隔開關(guān)沒有專門的滅弧設(shè)備不能切斷負(fù)荷電流和短路電流，所以必須在電路在斷路器斷開電路的情況下才能夠操作隔離開關(guān)。 2、在電氣設(shè)備維修時，供給一個電氣距離，并且是一個顯著可見的斷開點，用以保證保護(hù)人員的人身安全。 3、隔離開關(guān)不能帶負(fù)荷操作：不能帶額外負(fù)荷或大負(fù)荷操作，不能分、合負(fù)荷電流和短路電流，但是有滅弧室的能夠帶小負(fù)荷及空載線路操作。 4、通常送電操作時：先合阻隔開關(guān)，后合斷路器或負(fù)荷類開關(guān)；斷電操作時：先斷開斷路器或負(fù)荷類開關(guān)，后斷開阻隔開關(guān)，63A 負(fù)荷隔離開關(guān)P3-63/IVS-RT/N。 5、選用時和其它的電氣設(shè)備一樣，其額外電壓，63A 負(fù)荷隔離開關(guān)P3-63/IVS-RT/N，63A 負(fù)荷隔離開關(guān)P3-63/IVS-RT/N、額外電流、動安穩(wěn)電流、熱安穩(wěn)電流等都必須契合使用場合的需求。隔離開關(guān)帶給人們的便利，并不是單一的**只是一個開關(guān)！63A 負(fù)荷隔離開關(guān)P3-63/IVS-RT/N</p><div style="width:100%;text-align: center;"><img

1、隔離開關(guān)控制閉鎖回路改進(jìn)原理在隔離開關(guān)控制、閉鎖回路中串入隔離開關(guān)輔助觸點，即母線側(cè)隔離開關(guān)控制閉鎖回路中串入線路側(cè)隔離開關(guān)常閉輔助觸點，線路側(cè)隔離開關(guān)控制回路串入母線側(cè)隔離開關(guān)常開輔助觸點。 2、改進(jìn)接線的優(yōu)點 (1)此種改進(jìn)接線不*保留了原有隔離開關(guān)控制接線的優(yōu)點，**主要的是能有效防止違反開關(guān)、刀閘操作原則的違規(guī)操作，減少不必要的事故發(fā)生。 (2)此種改進(jìn)接線簡單、可靠，投資也較少。適用于采用電磁鎖防誤的接線及氣動操作、電動操作、電動液壓操作的隔離開關(guān)的控制接線。 (3)在沒有采用程序鎖防誤的裝置中，相當(dāng)于程序鎖的作用。</p><p style="text-indent:25px">【浩蘊自動化】負(fù)荷開關(guān)和隔離開關(guān)的區(qū)別 ***點區(qū)別就是兩者所切斷的電流不一樣。因為隔離開關(guān)沒有滅弧裝置，所以只適合切斷無負(fù)荷的電流，無法切斷負(fù)荷電流、短路電流，所以隔離開關(guān)電器只能在電路安全斷開的情況下才能安全的進(jìn)行操作，并且是嚴(yán)謹(jǐn)帶有負(fù)荷操作，以免造成安全事故。負(fù)荷開關(guān)因為有滅弧裝置，所以能夠切斷過載電流以及額定的負(fù)荷電流，但是同樣的不能切斷短路電流。（電氣小強(qiáng)提醒您：切斷短路電流，找斷路器幫忙。）杭州浩蘊-伊頓穆勒ETAON品牌授權(quán)商！</p><div
