1.overview

DTS6607、DSS6607The three-phase electronic energy meter adopts imported specialized large-scale integrated circuits,16positionA/DConversion, digital multiplier, application of digital sampling processing technology andSMTProcess, a new type of instrument designed and manufactured based on the actual electricity consumption of industrial users. This meter uses an independent three unit metering module to accurately measure the active energy of three-phase forward and reverse directions. Measurement errors have excellent long-term stability.Its performance meets the requirementsGB/T17215-2002The standard specifies the technical requirements for three-phase energy meters.

Main features: It has good resistance to electromagnetic interference, low self consumption, high precision, anti electricity theft, wide range, long life, and can display liquid level.

This meter is suitable for an ambient temperature of -10~50℃, relative humidity not exceeding85%.

2.function and characteristic

1It has the function of bidirectional measurement of active energy, and the LCD display shows the total amount of electricity;

2HavingRS-485And infrared communication, which can remotely and conveniently read the total power of the energy meter;

3Can set or retrieve parameters such as total power consumption, instrument constant, meter address, meter password, etc;

4Equipped with a programming switch, it can be programmed online;

5The chip has a watchdog system inside, making data more secure and reliable, and power outage data can be stored for a long time (continuous power outages can be stored for more than 10 years);

6Isolated power sources, namelyCPUMeasurement section andRS485The interface provides reliable working power supply.

7It has a phase failure indication function.

8Communication protocol

According to the Communication Protocol for Multi functional Energy MetersMulti-function watt-hourmeter communication protocol 》DL/T 6451997—

3.The standards of the power industry in the People's Republic of China shall be implemented.

Working principleDTS6607、DSS66071The working principle of the three-phase static energy meter is shown in the diagram

As shown.

This electric energy meter adopts a three-phase power supply mode and can work normally under any single-phase power supply situation.16When the electric energy meter is working, the voltage and current are sampled separately by the sampling circuit, and then sent to the large-scale dedicated integrated circuit for buffering and amplification, and thenpositionA/DThe converter converts it into a digital signal, which is then processed by a digital multiplier and sent toCPUProcess it, and finally,CPU

4.Send the processed data to output units such as the display section and step counter as needed.

5.1Installation and wiring

5.2The electricity meter has been inspected and approved before leaving the factory, and is sealed with a lead seal. If there is no lead seal or if it has been stored for too long, relevant departments should be asked to recheck and seal it before installation and use.There are hook screw holes on the upper part of the electricity meter, which can be used forM42Fixed with hook screws, the lower part of the electric meter hasFor installation holesM4X10perhapsM4X12

5.3Ordinary screws are fixed on the terminal block. The installation and dimensions of the electric energy meter are shown in the diagram below:

The electricity meter should be wired correctly according to the wiring diagram attached on the back of the terminal box cover, and the wiring screws should be tightened.5.3.14.1Functional terminal wiring: (Figure)
