DTZ719 Three phase Intelligent Energy Meter

DTZ719 Three phase Intelligent Energy MeterTechnical parameter indicators:

Main functions
1. Electric energy metering function

① Measurement parameters: measurable active power, reactive power, forward active power, reverse active power, forward reactive power, reverse reactive powerFour quadrant reactive power and other electrical quantities.
② Monitoring parameters: can monitor real-time values of voltage and current of each phase, can monitor the total three-phase and active power of phases A, B, and CReal time parameters such as reactive power, power factor, phase angle, and phase.
③ Time sharing function: It has the function of dividing peak, off peak, off peak, and off peak periods into multiple rates, and can also select peak, off peak, and off peak periods for power sharingYes, in short, it is applicable to the time of use rate requirements across the country.
④ Data storage: It can store monthly electricity data for 13 months, and can store monthly total, peak, peak, and flat dataData such as valley electricity consumption. It can store hourly power data within 48 hours. Can store voltage at 5-minute intervals

Current, positive and negative active and reactive power data.
⑤ It has the function of recording 6 types of load curves.
⑥ Display function: It can display Zui's monthly electricity data for the past three months; The data stored at intervals of hours and minutes can be accessed through

RS485 communication interface reading.
2. Anti electricity theft function
① Open lid recording function to prevent illegal changes to the circuit.
② Open the wiring cover function to prevent illegal changes to the meter wiring.
③ Voltage qualification rate and voltage loss recording function to prevent users from illegally removing or cutting off voltage wiring. If it has occurred, it can

By recording the time, calculate the amount of electricity lost and provide a basis for replenishing the electricity.
④ The function of recording current loss and phase failure prevents users from illegally short circuiting current connections. If it has occurred, the recorded time can be used

Calculate the amount of electricity lost and provide a basis for replenishing the electricity.
⑤ Current imbalance record: It can alert users to intercept electricity at the front end of the meter wiring.
⑥ Power off recording function to prevent users from illegally removing the working power supply of the electricity meter. If it has occurred, the recorded time can be used

Calculate the amount of electricity lost and provide a basis for replenishing the electricity.
⑦ Reverse electricity consumption is included in forward electricity consumption. If the user connects the current wire in reverse, the meter will still run forward without stealing electricity

Use it.
⑧ Reverse phase sequence alarm, if the user illegally connects the wires, the electricity meter will sound an alarm. Unless the wires are connected correctly, the alarm will continue to sound. If the above situation occurs, the meter will display an alarm sign. If a meter reading system is installed and connected to the meter, the meter reading system will immediately respond

An alarm has occurred.
3. Meter reading method
①DTZ719 Three phase Intelligent Energy MeterBy pressing the buttons on the electricity meter, the total monthly electricity, voltage, current, and power of the meter can be queried on the LCD screenPower factor and other data.

② By using a handheld infrared meter reader, various electricity data from the meter can be read.
③ Dual RS485 communication ports for meter reading, in conjunction with the meter reading system, can read various electricity data from the meter. And support

DL/T645-2007 Multi functional Energy Meter Communication Protocol.
