你知道為什么要用隔離變壓器嗎？

隔離變壓器原理

隔離(li)變(bian)壓(ya)(ya)(ya)器的原理(li)與普通變(bian)壓(ya)(ya)(ya)器相(xiang)同。它(ta)們都(dou)使(shi)用電磁感應(ying)原理(li)。隔離(li)變(bian)壓(ya)(ya)(ya)器一般指1:1變(bian)壓(ya)(ya)(ya)器。因為(wei)次(ci)級線圈沒有接地(di)。二次(ci)線與地(di)之間(jian)無電位差。使(shi)用安全。常用作維修電源。

隔(ge)離(li)變(bian)壓器(qi)(qi)(qi)(qi)不(bu)全(quan)是1:1變(bian)壓器(qi)(qi)(qi)(qi)。控制(zhi)變(bian)壓器(qi)(qi)(qi)(qi)和管(guan)式(shi)設備的電(dian)源(yuan)也是隔(ge)離(li)變(bian)壓器(qi)(qi)(qi)(qi)。諸如管(guan)放大器(qi)(qi)(qi)(qi)、管(guan)收(shou)音(yin)機、示波器(qi)(qi)(qi)(qi)和車(che)床控制(zhi)變(bian)壓器(qi)(qi)(qi)(qi)等電(dian)源(yuan)都是隔(ge)離(li)變(bian)壓器(qi)(qi)(qi)(qi)。例如，為了(le)彩(cai)電(dian)的安全(quan)維護，常(chang)用1比1的離(li)變(bian)壓器(qi)(qi)(qi)(qi)。隔(ge)離(li)變(bian)壓器(qi)(qi)(qi)(qi)更常(chang)用，也用于空調。

隔離變(bian)壓器俗稱(cheng)安全變(bian)壓器，一般用于(yu)隔離市政電網電力的雜質和(he)維護設備。

為(wei)什么要(yao)使(shi)用(yong)隔(ge)離(li)變壓(ya)器？

首先，使(shi)(shi)用(yong)隔(ge)離變(bian)(bian)壓(ya)(ya)器需要了解(jie)我國的供(gong)電(dian)(dian)(dian)(dian)系(xi)統。在(zai)為低壓(ya)(ya)用(yong)戶供(gong)電(dian)(dian)(dian)(dian)時(shi)，我們的供(gong)電(dian)(dian)(dian)(dian)系(xi)統一(yi)(yi)般(ban)采用(yong)三相(xiang)四線(xian)(xian)制。中(zhong)性線(xian)(xian)接(jie)(jie)地，最受(shou)歡迎的是(shi)(shi)到居民家的電(dian)(dian)(dian)(dian)線(xian)(xian)。一(yi)(yi)條是(shi)(shi)相(xiang)線(xian)(xian)（火線(xian)(xian)），另一(yi)(yi)條是(shi)(shi)零線(xian)(xian)。當人(ren)(ren)體(ti)與地球處(chu)于(yu)同(tong)一(yi)(yi)位(wei)置時(shi)，它與地球處(chu)于(yu)同(tong)一(yi)(yi)位(wei)置。當接(jie)(jie)觸熱地板(ban)時(shi)，電(dian)(dian)(dian)(dian)流會通(tong)(tong)過人(ren)(ren)體(ti)，與大地形成(cheng)(cheng)電(dian)(dian)(dian)(dian)路，造(zao)成(cheng)(cheng)觸電(dian)(dian)(dian)(dian)危(wei)險。如果(guo)使(shi)(shi)用(yong)隔(ge)離變(bian)(bian)壓(ya)(ya)器，會更安全，因(yin)為一(yi)(yi)級和二級通(tong)(tong)過磁場交換能(neng)量，并且沒有物理硬連接(jie)(jie)。即使(shi)(shi)人(ren)(ren)體(ti)接(jie)(jie)觸到帶(dai)電(dian)(dian)(dian)(dian)的物品(pin)，也會因(yin)為人(ren)(ren)體(ti)和地球在(zai)同(tong)一(yi)(yi)個(ge)地方。鉆頭，使(shi)(shi)帶(dai)電(dian)(dian)(dian)(dian)部分的電(dian)(dian)(dian)(dian)位(wei)較低，不會造(zao)成(cheng)(cheng)觸電(dian)(dian)(dian)(dian)危(wei)險。使(shi)(shi)用(yong)隔(ge)離變(bian)(bian)壓(ya)(ya)器時(shi)，應注意兩點(dian)：

1、隔(ge)離變壓器(qi)二次端(duan)不能接地；

2、人體不(bu)能同時接觸二次端，否則有(you)觸電的(de)危險(xian)。
