Overview

DDZY193The single-phase cost controlled intelligent energy meter (hereinafter referred to as the energy meter) is a new generation of intelligent energy meters developed based on the national grid's "unified and strong smart grid" construction requirements, using large-scale integrated circuits and digital sampling technology. It is mainly used for energy measurement of single-phase residential users in the smart grid. The main performance indicators of the electric energy meter meet the requirementsGB/T 17215.211—2006General Requirements for AC Measurement Equipment Experiment and experimental conditions-第11Part: Measurement EquipmentGB/T 17215.321—2008AC Measurement Equipment Special requirements-第21Part: Static active energy meter（1Level and2Grade)GB/T 17215.301-2007Multi functional electric energy meter Special Requirements "GB/T 15284-2002Multi rate electricity meter Special Requirements "DL/T 614—2007Multi functional electric energy meterDL/T 645—2007Multi functional Energy Meter Communication ProtocolQ/GDW 1355—2013Type Specification for Single phase Intelligent Energy MetersQ/GDW 1354—2013Functional Specification for Intelligent Energy MetersQ/GDW 1364—2013Technical Specification for Single phase Intelligent Energy MeterQ/GDW 1365—2013The relevant requirements of standards such as the Technical Specification for Information Exchange Security Certification of Intelligent Energy Meters.

Main functional features

The design and structure of the electric energy meter can ensure that it does not cause any danger when used under rated conditions;

■ It has bidirectional total, peak, off peak, flat, and valley rate time period electricity metering, and can set combined active power. Colleagues can record programming events, reset events, calibration, power failure, closing and opening events

■ Has sharp, peak, flat, and valley features4A rate,14The minimum interval between daily time periods is15minute

■ Through infrared interface andRS485The interfaces are respectively connected to the handheld computer andPCCommunicate with the machine, complete programming settings and meter reading

■ AdoptingLCDDisplay item by item or cyclically display the total, peak, average, and valley electricity consumption, as well as the electricity consumption of the previous month and the previous month, for easy meter reading. The electricity consumption display is6Bit integer,2Decimal places

■ Record12The total electricity consumption and energy data for each rate on the settlement date can be obtained through infrared andRS485Copy out the interface

The electricity bill calculation is completed in the remote electricity sales system, and the energy meter receives the opening and closing instructions issued by the remote electricity sales systemESAMWhen reading data instructions, strict password authentication and security authentication are required. Under the premise of ensuring safety, electrical parameters can be set

■ Alarm output
