描述
交流電首先經(jīng)過(guò)一個(gè)由保險(xiǎn)絲和壓敏電阻組成的保護(hù)電路,保險(xiǎn)絲主要起過(guò)流保護(hù)作用;壓敏電阻則起過(guò)壓保護(hù)作用。在正常工作情況下,電路的壓敏電阻相當(dāng)于斷路。當(dāng)電網(wǎng)電壓波動(dòng)或受外界影響(如閃電,電源突然接入等)而引起電壓瞬間激增時(shí),壓敏電阻會(huì)自動(dòng)導(dǎo)通,并由壓敏電阻和保險(xiǎn)絲組成回路。由于高壓下的壓敏電阻阻值較小,所以回路電流很大,保險(xiǎn)絲自動(dòng)斷開(kāi),這樣就起到了保護(hù)內(nèi)部電路的作用。該保險(xiǎn)絲是可以自恢復(fù)的,也就是說(shuō),它可以反復(fù)使用而無(wú)需更換。
