噴射式熔斷器是將熔體裝在由固體產(chǎn)氣材料制成的絕緣管內(nèi)。固體產(chǎn)氣材料可采用電工反白紙板或有機玻璃材料等。當(dāng)短路電流通過熔體時，熔體隨即熔斷產(chǎn)生電弧，高溫電弧使固體產(chǎn)氣材料迅速分解產(chǎn)生大量高壓氣體，從而將電離的噴射式熔斷器全絕緣設(shè)計，提高配網(wǎng)絕緣程度，降低事故發(fā)生率.尤其是城市配網(wǎng)，完全解決了傳統(tǒng)跌落式熔斷器的裸露點：封閉型結(jié)構(gòu)避免了內(nèi)部觸頭受污損引起接觸電阻增加的問題。保證設(shè)備電氣性能的有效性、并避免了熔斷器因污損引起的絕緣電阻下降問題。
噴射式熔斷器是利用金屬導(dǎo)體作為熔體串聯(lián)于電路中，當(dāng)過載或短路電流通過熔體時，因其自身發(fā)熱而熔斷，從而分斷電路的一種電器。熔斷器結(jié)構(gòu)簡單，使用方便，廣泛用于電力系統(tǒng)、各種電工設(shè)備和家用電器中作為保護器件。
