DT854 Three Phase Long-life Watt-hour Meter

      The type DT854 watt-hour meter has concentrated the new generation Of designning and the technique of manufacturing, adopting the first-class Domestic processing equipment and the advanced processing technology, And it has the first level of three prhse inductive long life watt-hour meter,Which is designed and manufactured according to electric power industrial Consumers practical operation.

     It features long life、wide load、high accuracy、high reliability, low Power conusmption etc. Each performance index of it conforms to GB/T17215.311 -2008 0.5,1.0&2.0 class A.C active watt-hour meter or GB/T 15282 -94 Reactive watt-hour meter.

1. The lock device is built on the full-load adjusting mechanism and light-load Adjusting mechanism, to keep good accuracy because of reducing Vibration of impacting and other factors effectively.

2. The electromagnetism system adopts 2.0 mm of steel plate, fixed on the aluminium Silicon alloy frame, it not only ensures strength of frame, but also enhances performance of meter.

4. The magnetic floationg bearing adopts aluminium nickel coboalt alloy then formation of processing, It features even magnetism, stable performance, low temperature coeffcient etc.

5. The magnet adopts aluminium nickel coboalt the formation of molding, to gurantee the damping components accuracy of orientation and reliability.

6. The carbon bearing adopts multi-compound material , after unique surface diffusion craft processing ,to reduce coeffient of frication effectively, making lubrication and wear-resisting be more promient, it can reduce side of pressure when the disc rotation, to gurantee meter use of life.

7. Simple reliable compensation for current components, wide load and flat curve.

 8. Measurement of flat curve, it causes error variable to be small and good unanimity when voltage,frequency,temperature,working postion and phase changing.
