一、保險絲符號及圖形
保險絲符(fu)(fu)號(hao)(hao)是用于在電路(lu)圖(tu)中表示各種(zhong)電路(lu)特性的標(biao)志,保(bao)險絲(si)的符(fu)(fu)號(hao)(hao)與(yu)(yu)電阻(zu)符(fu)(fu)號(hao)(hao)相似,與(yu)(yu)電阻(zu)符(fu)(fu)號(hao)(hao)的區(qu)別在于兩端的引線貫通(tong)方框,即(ji)在一(yi)(yi)根直線上再畫上一(yi)(yi)個長方形(xing),就是保(bao)險絲(si)的符(fu)(fu)號(hao)(hao)。
1、文字符號
保險(xian)絲的文字(zi)符號(hao)為:FU。
在電(dian)路圖(tu)中(zhong),保險絲的符(fu)號用(yong)FU表示,是fuse-link的簡稱。
2、圖形符號
保險絲的(de)圖形(xing)符號,如下(xia)圖所(suo)示:
保(bao)(bao)險(xian)絲(si)在電路圖(tu)中的位置是(shi)在電源(yuan)的輸(shu)入部(bu)(bu)分,即電源(yuan)一(yi)輸(shu)入就要通過保(bao)(bao)險(xian)絲(si),電源(yuan)的輸(shu)出部(bu)(bu)分也可(ke)以加(jia)保(bao)(bao)險(xian)絲(si)。
二、帶保險絲的開關插座如何接線
帶保險絲的開關插座,首先是(shi)(shi)把鏈接(jie)(jie)開(kai)關(guan)(guan)插(cha)(cha)座的(de)(de)所使(shi)用的(de)(de)電(dian)線(xian)(xian)(xian)(xian)(xian),通過電(dian)線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)皮的(de)(de)顏色,或者是(shi)(shi)給電(dian)線(xian)(xian)(xian)(xian)(xian)頭做記(ji)號,分(fen)清每根(gen)電(dian)線(xian)(xian)(xian)(xian)(xian)的(de)(de)功能(neng),帶(dai)保險(xian)絲(si)的(de)(de)插(cha)(cha)座開(kai)關(guan)(guan),大部(bu)分(fen)都是(shi)(shi)控制火(huo)線(xian)(xian)(xian)(xian)(xian)的(de)(de)進線(xian)(xian)(xian)(xian)(xian)端子,你把零線(xian)(xian)(xian)(xian)(xian)地線(xian)(xian)(xian)(xian)(xian)控制線(xian)(xian)(xian)(xian)(xian)按接(jie)(jie)線(xian)(xian)(xian)(xian)(xian)孔(kong)標(biao)注的(de)(de)符號依次(ci)插(cha)(cha)入固緊,把火(huo)線(xian)(xian)(xian)(xian)(xian)接(jie)(jie)在插(cha)(cha)座開(kai)關(guan)(guan)的(de)(de)保險(xian)絲(si)上邊的(de)(de)進線(xian)(xian)(xian)(xian)(xian)接(jie)(jie)線(xian)(xian)(xian)(xian)(xian)孔(kong)即(ji)可。
帶保險絲的開關插座如何接線?很簡單,先把電源線的火線接到保險絲的一個接(jie)口上(shang),另一個接(jie)口用導線(xian)連接(jie)到(dao)插(cha)座(zuo)的L接(jie)口上(shang),電源線(xian)的零線(xian)直接(jie)接(jie)插(cha)座(zuo)的N接(jie)口上(shang)。
