HXQ HX1 HX2 HX3 HX5 HX6 HX7 HX8低压核相器 带电显示核相仪是(shi)我公司根据用户(hu)需求(qiu),设计(ji)生产的与(yu)DXN8系(xi)列户(hu)内(nei)(nei)高压带(dai)电(dian)(dian)(dian)(dian)显示装(zhuang)置(zhi)(指示器(qi)面板设置(zhi)相位测试端)配(pei)套使用的HX2型相位比(bi)较(jiao)器(qi)(PC). 其内(nei)(nei)部电(dian)(dian)(dian)(dian)路(lu)采用低(di)电(dian)(dian)(dian)(dian)压低(di)功耗(hao)的发光元件,性(xing)能稳定,使用安全(quan),可(ke)靠性(xing)高.适(shi)用于户(hu)内(nei)(nei)3.6, 7.2,12,40.5kV,频率(lv)50Hz配(pei)置(zhi)户(hu)内(nei)(nei)高压带(dai)电(dian)(dian)(dian)(dian)显示装(zhuang)置(zhi)的双电(dian)(dian)(dian)(dian)源,多电(dian)(dian)(dian)(dian)源供电(dian)(dian)(dian)(dian)的变电(dian)(dian)(dian)(dian)所,配(pei)电(dian)(dian)(dian)(dian)所(特别是(shi)电(dian)(dian)(dian)(dian)缆进线时),在检(jian)修(xiu)后和(he)送电(dian)(dian)(dian)(dian)前(qian),无须打开开关柜柜门(men),即(ji)可(ke)在低(di)压端进行(xing)相位比(bi)较(jiao).
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(shi)器正常指示(shi)后，再进行其(qi)他操作。
