DT666, DS666 series three-phase watt-hour meter long life technology concentrate a new generation of meter design and manufacturing technology, The do20130111133503_1.pdftic market use first-class processing equipment and advanced processing technology.

It manufactures the high advanced class three phased mechanical meter according to our country industry user's actual operation situation. The average lifetime of this long life type is 25 years.

The meter has long life, wide load, high accuracy, high stability, low power consumption, easy adjustment and beautiful appearance etc features, and has passed the international authoritative institutions KEMA Netherlands authentication.

Function characteristics:

• First add the locking device of full load adjusting mechanism and light load adjusting mechanism in the same serials meters in China, and effectively eliminate the error effect due to vibration,shock and other external factors

• Magnetic bearing adapt high coercive force alnico 8 kinds of permanent magnet alloy matrix processing forming, with high magnetic stability, magnetic homogeneous, resistance to interference of outside magnetic field and temperature coefficient of resistance characteristic, guarantee the meter’s long-term stability.

• The electromagnetic system is made of 2.0 mm thick steel plate, and the special fixture fixed in aluminum silicon alloy frame, not only ensure the backplane overall strength, but also can improve the performance of the measurement .

•Because of special long life technology register, use the antirust aluminum bent frame, stainless steel shaft, the first shaft diameter is Φ0.6 mm. It decreases friction torque, and its mechanical load impact error change quantity (COS Φ = 10.05 lb conditions) is not more than ±0.3%, rotating shaft and hole without oil, and also has tolerance impact, not easy to damage etc features.

• The voltage core of voltage components assembly adopts high speed automatic blanking fold riveting molding. Orderly laminated ensure laminated riveting verticality acuities were 0.05 mm; Voltage coil adopt unique injection closed process, the insulation performance is excellent, impact resistance pulse voltage was ≥8.5 KV.

•Current core uses special order material, its initial permeability is high, good consistency and easy to make load characteristic curve compensation more flat.

• Magnetic steel is made of cobalt aluminum nickel and whole strong magnetic material , to ensure the damping element positioning accurate and reliable.

• Graphite bearing imported multivariate composite material graphite bearing, the unique surface diffusion process, effectively reduce the friction coefficient and needle, make its self lubrication and wear resistant characteristics more prominent, reduce the rotation process of lateral pressure, to ensure the service life of meter.

• Instrument measuring characteristic curve flat, voltage, frequency, temperature, and the error change is small caused by working position changes and phase sequence changes, batch products have good consistency.
