一、安规测试仪使用注意事项

注意的(de)(de)是直(zhi)流(liu)(liu)(liu)高压(ya)(ya)(ya)输出是负(fu)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya),而地为正极。测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)电(dian)(dian)(dian)(dian)容(rong)(rong)时,在(zai)(zai)电(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)两(liang)端加上电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)时有一充电(dian)(dian)(dian)(dian)过(guo)程,此(ci)时在(zai)(zai)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)电(dian)(dian)(dian)(dian)路(lu)中(zhong)(zhong)(zhong)有一充电(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu),当该电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大于(yu)所(suo)设定(ding)的(de)(de)漏电(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)值时,耐(nai)压(ya)(ya)(ya)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)仪就(jiu)会报警,使(shi)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)中(zhong)(zhong)(zhong)断(duan),无法进(jin)行(xing)(xing)(xing)(xing)。因此(ci),安规测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)仪在(zai)(zai)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)时,应(ying)(ying)缓(huan)慢增加电(dian)(dian)(dian)(dian)压(ya)(ya)(ya),充电(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)小(xiao)于(yu)所(suo)设定(ding)的(de)(de)漏电(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)值,直(zhi)到规定(ding)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya),进(jin)行(xing)(xing)(xing)(xing)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)。而不能(neng)采用固定(ding)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya),复位—启(qi)动方式进(jin)行(xing)(xing)(xing)(xing)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)、在(zai)(zai)交流(liu)(liu)(liu)回(hui)路(lu)中(zhong)(zhong)(zhong)相当于(yu)直(zhi)流(liu)(liu)(liu)回(hui)路(lu)中(zhong)(zhong)(zhong)的(de)(de)电(dian)(dian)(dian)(dian)阻,因此(ci),安规测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)仪在(zai)(zai)交流(liu)(liu)(liu)回(hui)路(lu)中(zhong)(zhong)(zhong)就(jiu)产生(sheng)一个(ge)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu),当该电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大于(yu)所(suo)设定(ding)的(de)(de)漏电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)值时,耐(nai)压(ya)(ya)(ya)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)仪就(jiu)会报警,使(shi)得测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)中(zhong)(zhong)(zhong)断(duan),无法进(jin)行(xing)(xing)(xing)(xing)。因此(ci),在(zai)(zai)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)前,应(ying)(ying)先计算好电(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)的(de)(de)容(rong)(rong)抗(Xc),再算出在(zai)(zai)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)电(dian)(dian)(dian)(dian)压(ya)(ya)(ya)下的(de)(de)回(hui)路(lu)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)值,然后调(diao)节耐(nai)压(ya)(ya)(ya)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)仪漏电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)预置(zhi)值,使(shi)其略大于(yu)回(hui)路(lu)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)值,再进(jin)行(xing)(xing)(xing)(xing)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)。J)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)电(dian)(dian)(dian)(dian)缆等分布电(dian)(dian)(dian)(dian)容(rong)(rong)大的(de)(de)元件(jian)(设备)要等同于(yu)电(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)。二、安规测(ce)(ce)(ce)(ce)(ce)试(shi)(shi)(shi)(shi)(shi)基本要求
