電容器種類之多，形同外表類型不同，類型相同可是電壓和其它方面還是不相同的，就比如說安規電容。安規電容是指用于這樣的場合，即電容器失效后，不會導致電擊，不危及人身。因為外部電源斷開后安規電容會迅速放電，人用手觸摸不會有觸電感。          
安(an)(an)規(gui)(gui)(gui)(gui)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)又分安(an)(an)規(gui)(gui)(gui)(gui)X電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)和(he)安(an)(an)規(gui)(gui)(gui)(gui)Y電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)。安(an)(an)規(gui)(gui)(gui)(gui)X電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)和(he)安(an)(an)規(gui)(gui)(gui)(gui)Y電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)雖然(ran)都歸于安(an)(an)規(gui)(gui)(gui)(gui)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)，可是它們外觀(guan)不相同，很好差異，在選購時就不怕選錯了。不過安(an)(an)規(gui)(gui)(gui)(gui)Y電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)中還分為Y1電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)、Y2電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)、Y3電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)和(he)Y4電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)，平常(chang)比(bi)較(jiao)(jiao)熟悉(xi)的(de)用(yong)的(de)比(bi)較(jiao)(jiao)多的(de)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)還是Y1電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)和(he)安(an)(an)規(gui)(gui)(gui)(gui)Y2電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)，而Y3、Y4電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)用(yong)的(de)比(bi)較(jiao)(jiao)少。
安規(gui)Y1電容(rong)和安規(gui)Y2電容(rong)外觀如出一轍，標稱電容(rong)量也是(shi)相(xiang)同的(de)(de)，弄不清楚它們之間的(de)(de)差異選(xuan)購真的(de)(de)很(hen)簡單踩雷(lei)買錯安規(gui)電容(rong)了。今日小編帶你(ni)們來(lai)看看安規(gui)Y1電容(rong)和Y2電容(rong)的(de)(de)差異吧。

1.腳距不(bu)同
安規Y1電(dian)(dian)容(rong)腳(jiao)距(ju)大(da)，通常(chang)安規Y1電(dian)(dian)容(rong)的腳(jiao)距(ju)是9.5MM或者10MM；安規Y2電(dian)(dian)容(rong)的腳(jiao)距(ju)是7.5MM。
2.耐壓不同
安規Y1電容(rong)耐壓(ya)高，安規Y1額(e)定(ding)電壓(ya)是500VAC，耐壓(ya)能夠達到4000VAC；安規Y2額(e)定(ding)電壓(ya)為500VAC，耐壓(ya)達到1800-2600VAC。
3.絕(jue)緣不同
兩(liang)者絕緣(yuan)(yuan)類型不同(tong)，安規Y1電(dian)(dian)容歸于雙(shuang)重絕緣(yuan)(yuan)（JD）；安規Y2電(dian)(dian)容歸于根本絕緣(yuan)(yuan)（JY）。
4.運用場合不同
兩者運用場合不同，安(an)規Y1電容用于跨接(jie)一二次(ci)側；安(an)規Y2電容用于跨接(jie)次(ci)側對維護大(da)地即FG線;
5.體積不同
容(rong)(rong)量相同(tong)但體(ti)積(ji)不同(tong)。容(rong)(rong)量相同(tong)的情況下，安(an)規Y1電容(rong)(rong)體(ti)積(ji)要比(bi)安(an)規Y2電容(rong)(rong)恰(qia)當大(da)一點。
弄清楚(chu)了安規(gui)Y1電(dian)容(rong)和安規(gui)Y2電(dian)容(rong)之(zhi)間的差(cha)異，在(zai)選(xuan)(xuan)購(gou)(gou)安規(gui)Y電(dian)容(rong)的時(shi)(shi)候(hou)使用什(shen)么場合就挑選(xuan)(xuan)什(shen)么樣(yang)的電(dian)容(rong)了。電(dian)容(rong)沒選(xuan)(xuan)對可不(bu)是小事，不(bu)只費錢(qian)費時(shi)(shi)間費精(jing)力，類(lei)型不(bu)對的電(dian)容(rong)用在(zai)產品上簡單出現各種問(wen)題，所(suo)以在(zai)選(xuan)(xuan)購(gou)(gou)電(dian)容(rong)時(shi)(shi)一(yi)定要注意類(lei)型類(lei)型問(wen)題。
