Product Introduction of Mine Explosion-Proof Watt-Hour Meter Box
The watt-hour meter box is composed of the explosion-proof joint box and shell.It''s equipped with
the three-phase three-wire active(reactive) watt-hour meter,current transformer and voltage transformer
and so on.
The watt-hour meter box is mainly used to calculate active or reactive electric power energy in the
AC power system,with the frequency of 50Hz,current of 200A or 400A,and voltage of 380V or
660V in the coal mine well or other industrial enterprises,with the surrounding medium containing
explosive gases(methane).
