Application
DDZY450C-Z type single phase tariff control smart electricity meter adopts the advanced metering chipset, digital data acquisition and treatment, SMT technology. This meter can measure the positive, negative, four-tariff rate energy, and save the data, recording the events of clearing data, time adjustment, programming, power failure, opening the meter cover, have energy pulse output, time signal output and etc, adopt CPU card, able to read and copy the data through wireless communication.
This meter complies with standard of GB/T 17215.321-2008 " Electricity metering equipment (a.c.) - Particular requirements - Part 21: Static meters for active energy (classes 1 and 2), GB/T 15284-2002 "Multi-tariff energy meter Particular requirements ", GB/T 17215.211-2006 "General requirements of Electricity metering equipment Test and test conditions - Part 11: Test equipments", DL/T 614-2007 "Multifunctional electricity meters", its communication protocol complies with DL/T 645-2007 "The communication protocol for multifunctional electricity meters"
Product Features
Electricity measurement function
1.To measure the positive and negative active energy, save the data, combine the active power according this setting.
2.Measurement at different time section, the active energy shall be accumulated according to different time section, save total, highest, high, normal, and low electricity consumption data.
3.Save the total electricity, and energy at each tariff at least 12 months, the dividing time for data saving is the 24 O'clock of the last day of each month, or the o'clock from 1th ~ 28th of each month as setting.
Local and remote tariff control
1. Tariff control is realized through CPU card, the electricity cost will be calculated by remote electricity selling system, the meter will not save and display the details related to electricity cost and price. When the meter receive the instruction of tripping, closing, reading and copying ESAM data, only after the strict password verification and safety confirmation are passed, then perform that instruction.
2. Able to perform remote operation and control through wireless communication.
Measurement and supervision
Able to measure, record, display the voltage, current (current of neutral line), power, power factor and etc at present, the measurement error not exceed ±1%.
Record the events
1. Able to record the occurrence time and energy data of being cleared.
2.Record the total programming times; the time, operator code, programming data marks of latest 10 times operations.
3.Record the total times of time adjustment (not including broadcasting time adjustment), the time and operator code of latest 10 times operations.
4.Record the total times of power failure, the occurrence and ending time of latest 10 power failures.
5.Record the latest 10 times of remotely controlling tripping and closing operations separately, the occurrence and electricity data of latest 10 operations independently.
6.Record the total times of opening meter cover, the occurrence and ending time of latest 10 events.
Tariff, time section
Two sets of tariff and time sections, they can be automatically converted at setting time, shortest time interval/section is 15 min, time section can cross over zero.
