| DD862/DD862a
|
| Application:dd862
and DD862a single phase electic meter are
in duction meter.It is used in calculating
50Hz single-phase AC active electrical energy.It
is compaosed of electromagnetic element.Moving
disc,bearing,damping magnet steel,counter
and regulator and regulator equipment.The
meter has high precision,high over-load,long
lifetime and so on features. |
|
| Structure
charateristics:The Voltage ir on
core adopts semienclosed insert model.The
current element adopts two-stage compensation
to have wide load property.The whole plasticenclosed
voltage coil.can withstand instantaneous large
voltage impulse.The double jewels bearing
or the magnetic-propelled bearing can ensure
long lifetime.The bipolar aluminium nickel
cobalt damping magnet steels have high coercivity,stable
magmetic property.The electric function is
in accordance with IEC521 international standard.
