DT862 Three Phase Energy Meter

SPECIFICATIONS

Main structure and working principle

The three-phase meter is of double-jeweled double-turntable structure, and the iron core is in separated form. The voltage element is semi-enclosed insert structure, stable performance, easy to maintain. Three-phase meter by the current, voltage components produce a moving into the magnetic field, so that the aluminum disk in the magnetic field to obtain the rotational speed is proportional to the size of the load current, so as to achieve the purpose of measuring electrical energy.

To achieve the purpose of measuring electric energy.

Installation and use

 meter in the factory by the inspection and qualified, and sealing lead seal, can be installed and used. If the meter is not sealed or stored for a long time, it should be re-calibrated by the relevant departments and then installed to ensure the accuracy of measurement.

The meter should be installed indoors in a dry and ventilated place, and the base plate for installing the meter should be placed on a solid fire-resistant wall that is not easy to vibrate, with a recommended installation height of about 1.8 meters, and the meter should be vertical and not tilted after installation.

 The meter should be connected to the line according to the specified phase sequence (positive phase sequence) and wired according to the wiring diagram on the cover of the end button box. It is better to use copper wires or copper connectors to avoid the meter burning out due to poor contact with the copper connectors in the end button box.

FUNCTIONS

♦ Meter base: bakelite or steel

♦ Meter main cover: bakelite or PC transparent anti UV or AS transparent

♦ Meter terminal cover: short or extended ( bakelite or PC transparent anti UV or AS )

♦ Material which is moisture-resistant, fire-retardant, high temperature molded

♦ Meter register: 5 or 6 digits, May select uni-directional function

♦ Bearing: Jewell or double Jewell or Magnetic

♦ The die-casing frame is alloy aluminum, molding with excellent mechanical strength, stable structure

♦ Voltage components and current components, using double insulation structure, have good electrical characteristics;

♦ Error adjustment mechanisms have fine adjustment mechanism.

♦ Starting: Under rated voltage and frequency and when cos Φ=1.0, the disc will ceaselessly rotate when the load current is not over 0.5% of basic current.

♦ Running with no-load: When no current in the current circuit and 80- 110% of rated voltage across the voltage circuit the disc will not make a complete revolution.

♦ Power loss: With no current in the current circuit and under rated voltage and frequency, the power loss in the voltage circuit is no more than 1.5W.

♦ May select extended terminal cover, which is for protecting the safety while using
