斷路器和空氣開關的區(qū)別斷路器的熱部分在過載時提供延遲保護



過載保護器的作用 多種延時規(guī)格適用于電感、電容、純電阻及要求較高的信號靈敏電路；高精度的液壓延時系統(tǒng)能緩沖外圍供電系統(tǒng)浪涌、電流瞬時抖動、閃爍，能完全避開電源瞬時不穩(wěn)定而造成設備冷起、設備瞬時斷電而導致設備故障及信息丟失；粘溫系數大的延時油的應用，適用于環(huán)境溫度-40℃～+85℃條件下使用，交替變化的環(huán)境溫度對延時脫扣影響小，且適用于高海拔6000m以下，如青藏鐵路信號控制電路使用

如果電流大小不隨電源相序的變化而變化，而總是與電動機某一出線端(電機的Ⅴ1接線端子)相接那根線上的電流，則說明是由于電動機自身缺陷導致的電流差。如果電流大小不隨上述兩個規(guī)律變動，而是反復變化不定，則表明電源、電動機二者均有缺陷。空載電流的測量因人而異。最常用的是鉗形電流表，先將鉗形表撥至量程，將鉗口張開，將一相電源線放入鉗口正，閉合鉗口，讀取數值。若數值偏小，應變換量程，如果待測電流小于5A，則應將導線在鉗口鐵芯上多繞幾圈后放入鉗口測量，所測數值應除以鉗口內的導線根數即為實測值，然后再測其余兩相電流值。
