Three phase four wire smart meter

Introduction:

The DTS1000/DSS1000 three-phase four wire smart meter adopts advanced metering chips for accurate measurement; Adopting digital calibration technology and modular design, it has the characteristics of low power consumption, high accuracy, stable performance, easy installation, and easy maintenance. This energy meter has a prepaid function, which allows for payment before use of electricity, effectively preventing the occurrence of electricity bill arrears. It is an ideal product for industrial users and other large electricity consumers to measure their energy consumption. The product complies with the requirements of GB/T17215.321-2008 and GB/T18460.3-2001 standards.

1、 The characteristics of a three-phase four wire smart meter are as follows:

(1) Strong ability to prevent electricity theft and electromagnetic interference;

(2) Stable performance, high accuracy, and low self power consumption;

(3) Single phase card meters and three-phase card meters can share the same management system;

(4) Adopting high-power and high reliability magnetic holding relays, with a wide range and strong overload capacity;

(5) Using logical encryption cards and DES dynamic encryption algorithm, the data is reliable and will not be cracked;

(6) IC cards transmit data bidirectionally, with one meter and one card. If a card is lost, no data will be lost. When a new card is used, the original card will be automatically reported as lost;

(7) Prepaid function: Pay first before using electricity, automatically cut off power when the remaining power is zero, and restore power automatically after payment and card insertion;

(8) When the remaining power is low, it has two levels of alarm functions: constant display alarm and power-off alarm, reminding users to purchase electricity in a timely manner.

3、 Function details of three-phase four wire smart meter:

(1) Measurement parameters: can measure active power, reactive power, forward active power, reverse active power, forward reactive power, reverse reactive power, four quadrant reactive power, etc.

(2) Monitoring parameters: It can monitor real-time values of voltage and current in each phase, as well as real-time parameters such as active power, reactive power, power factor, phase angle, and phase of the three-phase total and A, B, and C phases.

(3) Time sharing metering function: Time sharing metering of forward and reverse active power, four quadrant reactive power, and maximum demand. Data storage function: Time division metering of active and reactive electricity, capable of storing 12 months of historical electricity data.

(4) Data storage function: Time division metering of active and reactive electricity, capable of storing 12 months of historical electricity data.

(5) Load curve function: It has 6 types of data recording load curve functions; You can freely choose to draw a curve graph from data such as voltage, current, frequency, power and power direction, power factor, total reactive power, four quadrant reactive power, current demand, etc.

(6) Display function: wide viewing angle, large screen LCD display, with rich status indication and Chinese character auxiliary prompt information; It can display the monthly electricity consumption data for the past three months.

(7) Anti electricity theft function: It has event recording functions such as lid opening, voltage loss, current loss, phase failure, current imbalance, power failure, reset, reverse phase sequence, and reverse electricity being included in forward electricity, to prevent users from illegally removing or cutting off voltage and current wiring; Monitor the operation status of the electricity meter.

(8) Data output and communication functions: RS485 communication port and carrier communication interface for meter reading, in conjunction with the meter reading system, can read various electricity data from the meter. And supports DL/T645-2007 multifunctional energy meter communication protocol.
