Electricity meters or time-sharing electric energy meters, multi-rate electric energy meters, and multiple-rate electric energy meters, commonly known as peak-valley electric meters, are a kind of electric energy meter provided in recent years to meet the needs of peak-valley time-of-use electricity prices.
It can measure the power consumption of peak, trough, and flat periods according to the predetermined peak, valley, and flat time periods, so as to adopt different electricity prices for the power consumption at different times, play the role of electricity price adjustment, 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 use equipment.
working principle
The electric energy meter is composed of two main functional blocks: 1. Electric energy measurement part, 2. Microprocessor part. The electric energy measurement 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 that can be read. Including: remaining power, total, peak, peak, valley, flat power, etc.
2. Battery reminder
When the user uses electricity, the power meter counts down. When the remaining power in the meter is equal to the alarm power, the user will be reminded by means of tripping and power failure.
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.
Commonly used logo
L total remaining amount
U spent the total amount
E to use the total number of degrees
F used to reduce the number of peak power
G used to go to the valley
Beijing time in table D
Normally displaying F and G indicates 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.
Note: The electric energy meter should be wired according to the wiring diagram on the terminal box.
