The use and structural characteristics of three-phase electricity meters

This meter is used to measure the three-phase four-wire AC active energy with a rated frequency of 50HZ and a reference voltage of 3×220/380V. The base frame of the watch is made of high-quality aluminum alloy die-casting, and after aging treatment, it has good stability. It adopts double gemstone rotating bearings to reduce the friction torque. Flexible, using high coercivity alloy permanent magnet steel, the performance is more stable. The overload multiple of the watch can reach 4 times, and it has the characteristics of strong overload capacity, good error linearity, stable quality, designed service life of up to 15 years, and reliable performance.
