On the Ia of degree table enters, Ib enters and entered with Ic, after electric current is by first piece of kilowatt-hour meter, it will return to that Ia goes out, Ib goes out to go out with Ic；
2nd, Ia is gone out, Ib go out to go out to be connected to Ic second piece of kilowatt-hour meter Ia enter, Ib enters to enter with Ic, electric current flows through second piece
After kilowatt-hour meter, the Ia of second piece of kilowatt-hour meter is gone out, Ib goes out to go out to connect together with Ic, be connected in N phases；
3rd, the voltage transformer secondary line for being used to measure in important Electricity customers transformer station is connected to first block of electricity
Spend on Ua, Ub and Uc of table, using mode in parallel, be connected on Ua, Ub and Uc of second piece of kilowatt-hour meter；
3rd, wireless communication module is connected in the data transmission terminal of two pieces of kilowatt-hour meters, transfers data to power supply department monitoring master
Machine, the transmission intercal of each data are set to N seconds, the sum of the important Electricity customers of N=10Sx；
4th, set up monitoring host computer in power supply department, the kilowatt-hour meters of all important Electricity customers in collection institute restriction without
The data that the transmission of line communication module comes；
5th, power supply department monitoring host computer to by wireless communication module transmit Lai data classify, by different important use
Two pieces of kilowatt-hour meters of electric client are respectively defined as important Electricity customers title kilowatt-hour meter A and important Electricity customers title kilowatt-hour meter B；
6th, power supply department monitoring host computer is analyzed each important Electricity customers kilowatt-hour meter A and kilowatt-hour meter B data, when
When some important Electricity customers kilowatt-hour meter A and kilowatt-hour meter B data are unchanged for three days on end, warning window 1, alarm are ejected in prison
Information is：Certain Electricity customers kilowatt-hour meter data exception；
When some Electricity customers kilowatt-hour meter A and kilowatt-hour meter B data occurred in 3 days, power supply department monitoring host computer
Using the most kilowatt-hour meter data of cumulative data sum as variable；
When some Electricity customers kilowatt-hour meter A data change for three days on end and certain kilowatt-hour meter B data for three days on end without
During change, power supply department monitoring host computer ejects warning window 2 using kilowatt-hour meter A data as right value, and warning message is
" certain Electricity customers kilowatt-hour meter B fault alarms "；
When some Electricity customers kilowatt-hour meter B data change for three days on end and certain kilowatt-hour meter A data for three days on end without
During change, power supply department monitoring host computer ejects warning window 2 using kilowatt-hour meter B data as right value, and warning message is
" certain Electricity customers kilowatt-hour meter A fault alarms "；
The beneficial effects of the invention are as follows：
1st, the present invention realizes the active and standby function of measuring of important Electricity customers kilowatt-hour meter, improves the stability of continuous data
And reliability, reduce the extremely caused loss of charging for electric company.
2nd, the present invention makes important Electricity customers kilowatt-hour meter realize abnormal alarm function, can find important electricity consumption visitor in time
The exception of family kilowatt-hour meter and giving is handled；
3rd, the present invention as single ammeter measuring accuracy, can't cause data in addition to it can reach target
Error etc. is abnormal；
4th, cost of the present invention is low, is easy to implement, and in addition to suitable for important Electricity customers, can also use and typically use
In the watt-hour meter box of family, there is extensive promotional value.
Brief description of the drawings
Fig. 1 is the wiring diagram of the present invention.
