    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
