Specifications
a kind of AC single-phase active meter produced by us with electricity-theft prevention on an induction watt-hour meterCompared to common induction type watt-hour meter,they have another more current coil,so that complicate measuring lines.The dispensers adopt not only positive and negative accumulating counter,but two directions drive.
Besides the stableness and reliability of induction type watthour meter,they have the following function:
1.anti-jumper lines
When users thieve electricity by the means of short circuit or diffluence,common meter will stop driving or slow driving resulting in electricity being thieved,but this kinds of products will drive in positive direction at a speed by 100%-112% according to short, so that not only prevent thief from thieving eleltricity but punish the thief.
2.anti-backrewinding(tranposition between input and output lines)
When users thieve electricity by the means of exchangeing the position of input and output mon watthour meter will reduce accumulative electricity consumption for dispenser’s negative count caused by electric meter’s inversion,but this kind of dispensers will accumulate normally althought the watthour meter resersed,so that they can stop thieves from thieving electricity.
3.escape stop
The common joint of voltage component and current component of common watthour meter will be connected with metallic crotchet on junction box,so when the thieves pull out the metallic crotchet,the watthour meter will stop driving resulting in electricity being thieved.While this type metallic crotchet is installed in box,so that the thieves can not thieve electricity by pulling out crotchet.
4.anti-inversion
When users reverse watthour meter by using the inversion device or advanced electricity-theft device,common watthour meter will reverse resulting in electricity being thieved,while this type of peoducts will continously accumulate electricity positive direction.
