Application range

1.The active power KWH meter of these series products fit the standard of GB/T15283-1994《0.5,land 2 class AC active power KWH meter》allkinds of requirement,reactive power KWH meters fit the country standard of GB/T15282-1994<<reactive power KWH meter>> all kinds of technical requirements.

2.electric energy meter can be made connection directly and through meter use current transformer or meter voltage transformer of connection two ways.

3.Starting: the electric energy meter's dial can start and move around continuous when the reference voltage,reference frequency and cos∮=1 ,load current is not more than the KWH meter's starting current.

4.Cureeping: when the electric energy meter has no current,the voltage that added voltage wire is the reference voltage80%-110%,the meter's dial can't move one around.

5.Current medium performance: the electric energy meter can be worked very well when it through lashing wave shape is the standard1.2/50□waveform,the crest value is6Kv lashing voltage. The meter's wire line can be tested for 1 minute when the earth voltage is 2Kv,frequency is45-65Hz actually sine waveform AC voltage.

Basic feature
1.This productis a new kind machinery induction-type electrical energy metering pliance. Ltadopts high coercive force aluminium nickel cobalt meterial to make the special structuremag-netic hanged(magnetic-propelled)bearing. When it is electrified to operate, interrepulsion is produced betwwn the bearing and the anxle so that it is in suspend station,The frictionloss is very small.lt not noly reduces energy exhaustion by a wide margin, bur also prolongs lifetime to20 years and above.
2.After the electromagnetic coil has been vacuum varnished and sealedin,then couerd theinsulation shiele,in order to increase heat conduction capacity and sealed in,then corerd the insullation shield,in lrder to increase heat conduction capacity and machinery strength,control tomperature rise and buzzer noise,and resist dampnsess,and 8kv 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.

Main feature
Three phase four wire electric_energy_meter is a kind of response KWH meter,it is used in measuring the energy of the reference frequen cy is 50HZ three phase AC active power and reactive power.DX862,DX864,DX865,DX863 are three phase reactive power meter.

Application
Series electronic single-phase electric meter is the most advanced static electronc meter in China.The meter designs use large-scale integrated circuit,high reliability step motor, it can meter the AC single-phase active energy (voltage rating:220V;frepuency 50Hz),positive and negative two directions and accumulates in one direction.The test signal is isolated by phototr ansistor; it also has the function of anti-fraud, and indicates it's operation situation onflash light, so it could be manged very easy.
The puality technical norm of the products is in accordance with the GB/T17215-2002 nationalstandard and IEC 61036 intemational standard.

Principle
The meter samples the voltage and the current at the voltage divider and the current div ider built in the meter.These samples are went to the amplifier and multiplier,output of the multiplier is processed by the integrated circuit V/F conversion,frequency divider,power drive circuits to provide plus to drive step motor and mechanical register to accumulate custmer's electrical energy consume.

Technical indes
High accuracy:error<±1.0% 1 Class( <±2.0%2class)High sensitivety:initial staring current<0.4%1b Range of large load:current ov erload ratio>6 The temperature rage:The normal temperature of work::-10-45The extreme limit temperature:-40-65 Low power consumption:consumption of meter itself<1w
