Automatic Transistor Rectifier Station - Poland

price: contact company for price

Auto rectifier transistor station MAR-APST-2-250/6/200/250

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
