Abstract

It is found that some operating faults of the intelligent electric meters are caused by the performance of the built-in load switches. In order to determine the characteristics of the built-in load switches, the performance of the switches are tested and analyzed. The factors, including the complicate operating environment, electrode erosion under short-circuit current, and the control circuit defects, etc. have a great effect on the reliability of the built-in load switches. Under different operating temperatures, the resistance of the control coil is obtained, and it may cause the internal control expires. Faulty conduction of the electrode is caused by the inherent defects, or the electrode erosion under the short-circuit current, and the electrode erosion under pulsed current is presented. The failure of the built-in load switch is mainly determined by the design margin, and some problems are found in the control circuit. It can be concluded that it is beneficial to improve the possibility of fault detection of the built-in loads switches when considering the performance under different conditions. To improve the reliability of the built-in load switch, some technical specifications should be added to the specific content.
