Mining Explosion proof kilowatt-hour Meter Box

Purpose

Mining explosive-proof intelligent electronical KWH meter box is used to calculate the useful and unuseful power energy in the power system of AC 50Hz,rated power 380V,660V,1140V in coal mine well.

Electronical KWH meter box adopts all electronical intelligent design and its accuracy high, stability good, power consuming low.

It adopts technologies of electrical magnetic insulation and light electricity insulation, voltage input, current input and output are absolutely isolated, so its anti-disturbance strong, reliability high .

It can be configured with mine well power metering system to achieve the functions of remote power reading, automatic Statistics and report and it can carry accounting and statistics  of day, month, quarter, year by high peak, average ,low.

 Technical Features

1) display system voltage, triphase current ,useful power, power factor, accumulated powerquantity  and all phase useful power;

2) triphase isolation measurement,the data will not invert to solve the phase inverting cheating problem.

3) the wire connection is not restricted by phase sequence;

4) with standard RS485 communication interface,it can connect with communication branch and computer to form mine well power metering system to achieve remote power meter reading, automatically make statistics according to time range.
