lntelligent electric meter function characteristics
(1) Reliability
The accuracy is unchanged for a long time, and there is no need to run the school, no installation and transportation, etc.
(2) Accuracy
Width range, wide power factor, sensitive start, etc.
(3) Function
It can implement functions such as centralized metering, multiple rates, prepaid, anti -theft, and meetings of Internet access services.
(4) cost -effective
High cost performance, reserved expansion functions, and small affected raw materials price increases. [4]
Single -phase smart meter
Single -phase smart meter
(5) The alarm reminder When the remaining power is smaller than the alarm power, the meter often shows the remaining power to remind users to buy power; when the remaining power in the table is equal to the alarm power, the check -out power is disconnected. Should be purchased in time. [4]
(6) Data protection
Data protection adopts a full -solid integrated circuit technology, and the data can be maintained for more than 10 years after power failure.
(7) Automatic power off
When the remaining power in the power meter is zero, the power meter will switch to automatically and the power supply is interrupted. The user should purchase the power in time at this time.
(8) Reprint function
Electric energy cards can write the cumulative electricity consumption, remaining power, and over zero power recovery of users to the statistical management of the management department in the electricity sales system.
(9) User random inspection function
Power -selling software can provide user sequences that provide data sampling power and provide priority random inspection according to the requirements.
(10) Electricity query
Insert IC card secondary display, the total power purchase, the number of electricity purchases, the last time purchase volume, the cumulative power consumption, and the remaining power.
(11) Over -pressure protection
When the actual power load exceeds the set value, the meter is automatically disconnected, inserted into the user card, and restored power supply.
