Basic feature ：
1.This products a new kind machinery induction-type electrical energy metering pliance, Ltadopts high coercive force aluminum nickel cobalt materiel to make the special structure mag-netic hanged (magnetic propelled) bearing.When it is electrified to operate,interruption is produced betwwn the bearing and the anxle so that it is in suspend station,The frictionless is very small.It not only reduces energy exhaustion by a wide margin,bur also prolongs lifetime to 20 years and above.
2.After the electromagnetic coil has been vacuum varnished and sealed in,the courser the insulation shiele, in order to increase heat conduction capacity and sealed in, then croerd the insulation shield,in lrder to increase heat conduction capacity and machinery strength, control temperature rise and buzzer noise,and resist dampness,and 5kv crest voltage thunber strucked.
3.Abopt structure model current compensation, simple construction strong overload-capacity,smooth error property curve.
The quality techniacal indes of the products is in accordance with the GB/15283-94 natioal standard and IEC521 intermational standard.
