电工仪表可靠性技术之研究

Research on Reliability Technology of Electrical Instruments

随着电工仪表使用越来越广泛,电工仪表的可靠性显得日益重要。分析了当前电工仪表可靠性方面存在的两个技术难点,提出了用研发磁耦合交流电流传感器、磁耦合交流电压传感器、具有二级保护和强过载功能的直流电流传感器和具有保护网络强过载功能的直流电压传感器来解决,并得到了成功应用。

With the increasing use of electrical instruments, the reliability of electrical instruments has become increasingly important. The two difficult problems concerned with reliability performance existing in the current electrical instruments are analyzed. The magnetic coupling AC current sensors, magnetic coupling AC voltage sensors, DC current sensors with secondary protection and strong overload functions, and DC voltage sensors with strong overload protection functions for the network are developed to solve these two problems, which has been successfully practised in application.
