熔斷器有個非常明顯的特點性能，就是安秒特性。對熔體來說，其動作電流和動作時間特性即熔斷器的安秒特性，也叫反時延特性，即：過載電流小時，熔斷時間長；過載電流大時，熔斷對安秒特性的理解，從焦耳定律上可以看到Q=I2*R*T，串聯(lián)回路里，熔斷器的R值基本不變，發(fā)熱量與電流I的平方成正比，與發(fā)熱時間T成正比，也就是說：當電流較大時，熔體熔斷所需的時間就較短。而電流較小時，熔體熔斷所需用的時間就較長，甚至如果熱量積累的速度小于熱擴散的速度，熔斷器溫度就不會上升到熔點，熔斷器甚至不會熔斷。因此，在一定過載電流范圍內(nèi)，當電流恢復(fù)正常時，熔斷器不會熔斷，可繼續(xù)使用。

style="text-indent:25px">熔斷器組成的三個部分主要由熔體、外殼和支座，其中熔體是控制熔斷特性的關(guān)鍵元件。熔體的材料、尺寸和形狀決定了熔斷特性。熔體材料分為低熔點和高熔點兩類。低熔點材料如鉛和鉛合金，其熔點低容易熔斷，因為其電阻率較大，所以制成熔體的截面尺寸較大，熔斷時產(chǎn)生的金屬蒸氣較多，只適用于低分斷能力的熔斷器。高熔點材料如銅、銀，其熔點高，不容易熔斷，但因為其電阻率較低，可制成比低熔點熔體較小的截面尺寸，熔斷時產(chǎn)生的金屬蒸氣少，適用于**斷能力的熔斷器。熔體的形狀分為絲狀和帶狀兩類。改變變截面的形狀可明顯改變?nèi)蹟嗥鞯娜蹟嗵匦?。熔斷器有各種不一樣的熔斷特性曲線，可以適用于不同類型保護對象的需要。熔斷器的參數(shù)和型號有哪些？</p><div
