Application

DD450 series long-life single-phase watt-hour meter is used for measuring single-phase AC active energy of reference frequency 50Hz or 60Hz. It has many features such as reliable structure, stable performan ce, long life, wide load, high accuracy, low power consumption, nice appearance and so on.

Structure features

1. The combination of current, voltage, damping magnetic steel parts with pedestal, as well as with base parts adopts
reinforced fastening, to ensure the parts in the meter can't move.
2. Strong magnetic property, magnetic bearing made of high stability material, the guiding part adopts import graphite
bearing of self-lubrication and anti-abrasion and stainless steel axle pin of high strength that constitute long-life
rotating element, so that the stability and long life of meter can be ensured.
3. Damping magnetic steel adopts alnico material, it has good temperature compensating characteristics.
4. The creeping needn't to be adjusted, can be finished by anti-creeping hole on the disc.
5. The voltage coils are imbedded or plastic sealed, it can withstand surge voltage more than 6kV.
