Automatic Transistor Rectifier Station - Polandprice: contact company for price
is designed for traction power supply working in underground
mines, the workings of non-hazardous or non-hazardous
methane and classified as “A” class coal dust explosion
hazard. Auto rectifier station MAR-APST-2-250/6/200/250
transistor consists of disconnector, power transformer and
switchgear and protection, located in a common housing,
which is equipped with skids or wheels.
Automatic transistor rectifier station MAR-APST-2-
250/6/200/250 is powered from HV side voltage of 3 kV and 6
kV. Secondary side station produces a voltage 200 V. The
voltage is rectified in the 6 diode rectifier to the value
of 250 V DC. The output voltage of the automatic transistor
rectifier station is unregulated (a constant value).
Housing of automatic transistor rectifier station MAR-APST-
2-250/6/200/250 was made in the form of frame construction.
It is welded with bending profiles. Housing is divided into
the following compartments:
- LV disconnector chamber,
- Transformer chamber,
- circuit breaker chamber and separation auxiliary
transformers (optionalseparation auxiliary transformers can
be located in the chamber transformer)
- LV chamber equipment (rectifier, power transistors, line
- Security and control chamber, where are protection of the
lines, programmable controllers, push buttons, relays,
contactors and visualization panel,
-outflow chamber (cable glands for connecting wires / cables
outflow - connected in LV chamber of apparatus).
Doors and covers chambers are made of steel (carbon steel,
galvanized steel, stainless steel, double galvanized or
stainless steel). The doors are equipped with hinges and
locks type baskvil. The door was sealed with rubber gaskets
glued from the inside. The filter uses a transformer
chamber, through which air is drawn to cool the power
transformer. The upper cover is equipped with a suction fan
filters for removing heat generated by the transformer
during operation. The IGBT transistors chamber also uses
cooling system - filters and fans.
Circuit breaker chamber and chamber LV apparatus is equipped
with an electric lock, causing the power supply off the
electrical system at the station opened the door of the
chamber. The door of HV disconnector chamber and the door of
the transformer chamber is equipped with a mechanical stop
that prevents them from being opened if the GN station
switch is in the attached.
Housing automatic transistor rectifier station MAR-APST-2-
250/6/200/250 can be placed on a truck equipped with skids
or wheels for easy transport station to the place of
