Time-of-use electric energy meter or time-of-use electric energy meter, multi-rate electric energy meter, multi-rate electric energy meter, commonly known as peak-valley electric energy meter, is a kind of electric energy meter provided in recent years to meet the needs of peak-valley time-of-use electricity price.
It can measure the electricity consumption of peak, trough and flat sections according to the predetermined peak, valley and normal periods, so as to adopt different electricity prices for electricity consumption in different periods, play the role of electricity price regulation, and encourage electricity customers Adjust the power load, shift peaks and fill valleys, use power resources rationally, and fully tap the potential of power generation, supply and consumption equipment.
The electric energy meter is composed of two main functional blocks: 1. Electric energy metering part, 2. Microprocessor part. The electric energy metering part transmits the working data to the microprocessor management system. The microprocessor management system provides status display and alarm signals according to the working status.
The main function
1. Battery display
There are multiple parameters to read. Including: remaining power, total, peak, peak, valley, average power, etc.
2. Power reminder
When the user uses electricity, the electricity in the electric energy meter counts down, and when the remaining electricity in the meter is equal to the alarm electricity, the user will be reminded by means of tripping and power-off.
3. Power off
When the remaining power in the electric energy meter is zero, the electric energy meter automatically trips and interrupts the power supply.
Common logo
L Total amount remaining
U spent the total amount
E use total degrees
F is the number of peaks removed
G uses the number of valley electricity
Beijing time in table D
Usually, F and G are displayed to indicate whether the current state of the time period is using peak power or valley power.
Use and maintenance
Indoor use: The bottom plate of the installation table should be fixed on a solid fire-resistant wall. The recommended installation height is about 1.8 meters, and there is no corrosive gas in the air.
Outdoor use: installed in a fixed meter box, waterproof and moisture-proof.
