CHARACTERISTIC
FEATURES
The EH-d09-7/0,5/0,2/0,1/4/01 type flame-proof transformer unit is an electric device suitable for working
within electric installations with the 1000V or 500V
rated voltages.This unit is assigned for supplying and
control of one-phase or three-phase receivers with the
rated voltages:
3x133V from one, protected outflow with possible
phase sequence change,
3x231V from two independent protected outflows,
42V from one protected outflow.
The unit is the anti-explosion structure device and,
according to Polish Geological & Mining Law rules, it
may be installed inside underground excavations of
the non-methane or methane mines with the methane
hazard grades: “a”, “b” & “c” or the coal dust explosion
hazard classes “A” & “B”. The used electrical protections and the applied control and cooperation system
with the technological blockades, using the intrinsically safe circuits, ensure safe cooperation with the
supplied mining devices and/or machines.
The unit structure has been developed according to
the 94/9/WE (ATEX) directive requirements.
Optionally the transformer unit is suitable for connecting of the data transfer system that enables
reading & sending the technological information to the
mine-head (e.g. to the dispatcher stand).
