退磁检查电流互感器在电流突然下降的情况下,互感器铁芯可能产生剩磁。如电流互感器在大电流情况下突然切断电源、二次绕组突然开路等。互感器铁芯有剩磁,使铁芯磁导率下降,影响互感器性能。长期使用后的互感器都应该退磁。互感器检验前也要退磁。退磁就是通过一次或二次绕组以交变的励磁电流,给铁芯以交变的磁场。从0开始逐渐加大交变的磁场(励磁电流)使铁芯达到饱和状态,然后再慢慢减小励磁电流到零,以消除剩磁。对于电流互感器退磁,一次绕组开路,二次绕组通以工频电流,从零开始逐渐增加到一定的电流值(该电流值与互感器的设计测量上限有关,一般为额定电流的20-50%左右。可以电流互感器电流互感器这样判断,如果电流突然急剧变大。广泛采用电液位计,应用在江河、琥珀、水库、渠道、水电站等工程中。特点常用的水位计有四种:玻璃管式,平板式、双色水位计和低地位水位计。玻璃管式水位计玻璃管式水位计,公称压力一般不超过1.6MPa,公称直径有DN15和DN20两种,玻璃管内径不应小于8mm,厚度不小于3mm。玻璃管式水位计主要由汽旋塞,水旋塞,玻璃管、排污旋塞和连接法兰等组成。锅炉内的水位高低和变化,透过玻璃管显示出来。玻璃管的中心线要与水位计汽、水旋塞的中心线同心,以防止玻璃管受扭曲应力而破裂。为了防止玻璃管爆破伤人,在带有钢球的水位计内,在旋塞内配有弹子,汽、水爆破的冲力使弹子自动关闭汽、水旋塞。同时还应安装防护罩。防护罩一般用较厚的耐温的钢化玻璃板制成。
