Overview
DTZY217 three-phase four wire cost control intelligent energy meter is a new generation of intelligent high-tech energy metering product developed and produced by Zhejiang Chentai Technology Co., Ltd. It adopts the latest integrated circuit technology and utilizes advanced software algorithms to design and manufacture according to relevant international (IEC) standards for electric energy meters, as well as China's power industry standards DL/T614-2007, DL/T645-2007, and national grid series standards. It integrates various measurement, monitoring, alarm, display, and communication functions, and can measure the total active and reactive power and time of use in both forward and reverse directions, as well as the total reactive power and time of use in four quadrants; Capable of measuring the total maximum demand for active and reactive power in both forward and reverse directions, as well as the maximum demand per minute, the total maximum demand for reactive power in all four quadrants, and the maximum demand per minute, and the date and time of occurrence of the maximum demand; Capable of measuring voltage, current, power factor, active power, reactive power, apparent power, and three-phase total active power, total reactive power, always present power, power factor, frequency, etc; Can detect and record events such as phase failure, voltage loss, current loss, and three-phase total voltage loss in each phase; Capable of detecting backup battery voltage and monitoring load conditions; Can detect events such as opening the meter cover and programming cover; Capable of remote and infrared meter reading, programming, monitoring, and calibration; And it has multiple expansion functions. Suitable for various power plants, substations, metering gateways, and enterprises and institutions.
Product Details
Display and indication
Adopting a large screen LCD display, providing rich graphic or textual prompt information; The display content can be queried through the button loop, and the display items can be configured as needed through the communication port; Provide LCD backlight for easy viewing. Support power outage wake-up function, which can wake up the energy meter through buttons or non-contact methods, and achieve screen display reading of electricity and infrared communication port reading of electricity and other data.
Measurement and Measurement
Real time measurement of phase voltage, current, active power, reactive power, apparent power, power factor, phase angle, total active power, reactive power, apparent power, total power factor, grid frequency, current active demand, current reactive demand, battery voltage, etc. Real time display of current meter operation status, grid operation status, cumulative battery online time, etc.
Time sharing metering function
Four rates; Built in two sets of time zone tables and two sets of daily time period tables, which can be programmed and configured as needed. The switching time between the two sets of time zone tables and the switching time between the two sets of daily time period tables can be set to achieve mutual switching; Within 24 hours, 14 time periods can be set, with a minimum interval of 15 minutes, and can be set across midnight; Support the setting of public holidays, with 254 holidays available.
Data storage function
Supports multiple freezing methods: daily freezing, hourly freezing, timed freezing, instant freezing, and agreed freezing.
Event recording function
Record the last 10 power outages, programming, timing, opening and closing of the meter cover, tripping, closing, event clearing, meter clearing, strong magnetic interference, and power supply abnormalities.
Load record
The load record content can be combined arbitrarily from the six data items defined in DL/T 645-2007, including "voltage, current, frequency", "active and reactive power", "power factor", "total active and reactive energy", "total reactive energy in the four quadrants", and "current demand". The interval time for load recording can be set within the range of 1-60 minutes; The interval time for recording each type of load can be the same or different. The storage space for load recording can record the total active energy, total reactive energy, and four quadrant reactive energy in both forward and reverse directions, with a data volume of 40 days at an interval of 1 minute.
Prepaid function
The characteristic of remote cost control energy meters is that smart energy meters achieve cost control functions through remote 485 encryption.
ALARM IN
Light alarm output, when abnormal states such as voltage loss, current loss, overload occur, the electricity meter lights up the backlight; After the alarm is cleared, the backlight will turn off.
communication interface
One far-infrared communication interface and one RS485 communication interface, with two independent communication ports. The communication protocol complies with DL/T645-2007 and its filing documents.
