The performance indicators of DT862 three-phase four wire active energy meter fully comply with GB/T15283-1994《0.5、1and2Technical requirements for level AC active energy meter.DT862The electromagnetic component of the series three-phase four wire active and reactive power meter is a separate structure, and the voltage core adopts a closed sample core punched as a whole, which rotatesThe system has undergone static balancing and its bearings are double gemstone structures with shock-absorbing springs, and the damping elements are made of aluminumcobalt34Magnetic steel,And use thermal magnetic alloy sheets to capture temperature compensation.An electric meter generates a magnetic field by combining voltage and current components, causing the disk to rotate under its action. The speed of the disk is proportional to the magnitude of the loadable current, achieving the purpose of measuring electrical energy.
◆ Purpose and structural characteristics: This table is used to determine the rated frequency50HZThe reference voltage is3×220/380VThe three-phase four wire AC active power system. The base frame of this watch is made of high-quality aluminum alloy die-casting and has undergone aging treatment, with good stability. It uses double gemstone rotating bearings to reduce friction torque. The two ends of the measuring instrument rotating shaft are made of gemstone structure, which makes rotation more flexible. It uses high coercivity alloy permanent magnet steel, which has more stable performance. The overload multiple of this table can reach4Multiple, with strong overload capacity, good error linearity, stable quality, and a design service life of up to15Characteristics such as reliability and performance. ◆Main technical indicators: 1.Accuracy level:2.0level 2.Rated voltage:3×57.7/100V,3×220/380V,3×380V 3.Basic current:1.5(6)A, 5(20)A, 10(40)A, 15(60)A, 20(80)A, 30(100)A 4.Rated frequency:50Hz 5.Environmental conditions: Operating temperature -25℃~+55℃ Extreme working temperature:-20℃-50℃ 6.starting current: ≤ 0.5%Ib 7.
