HX2-2低压核相器概述，HX2型

HX2-2低压核相器是我公司根据用(yong)(yong)户(hu)需求,设计生产的与DXN8系(xi)列户(hu)内高压(ya)带电(dian)(dian)(dian)(dian)(dian)显示装(zhuang)置(zhi)(指示器面板设置(zhi)相位(wei)测试端)配(pei)套使用(yong)(yong)的HX2型相位(wei)比较器(PC). 其(qi)内部电(dian)(dian)(dian)(dian)(dian)路(lu)采用(yong)(yong)低电(dian)(dian)(dian)(dian)(dian)压(ya)低功耗的发光元件,性能(neng)稳定,使用(yong)(yong)安全(quan),可靠性高.适用(yong)(yong)于(yu)户(hu)内3.6, 7.2,12,40.5kV,频率(lv)50Hz配(pei)置(zhi)户(hu)内高压(ya)带电(dian)(dian)(dian)(dian)(dian)显示装(zhuang)置(zhi)的双(shuang)电(dian)(dian)(dian)(dian)(dian)源(yuan),多(duo)电(dian)(dian)(dian)(dian)(dian)源(yuan)供(gong)电(dian)(dian)(dian)(dian)(dian)的变(bian)电(dian)(dian)(dian)(dian)(dian)所,配(pei)电(dian)(dian)(dian)(dian)(dian)所(特别是电(dian)(dian)(dian)(dian)(dian)缆(lan)进(jin)线时),在检修(xiu)后(hou)和送(song)电(dian)(dian)(dian)(dian)(dian)前,无须(xu)打开开关柜柜门,即可在低压(ya)端进(jin)行相位(wei)比较.

使用方法

两个同频率的信号，*个信号的过零点，与第二个信号的过零点之间的距离，可用相位角度做单位，也可用时间做单位，来比较相位差。相位比较前,首先要确保高压开关柜内部配线正确,即装配的电压传感器与电压指示器
之间的连接导线的相序要正确.当两个高压电源正常供电,在确认各电源开关柜上面的电压
指示器正常指示后，再进(jin)行其他(ta)操作。
