Product Description

PURPOSE

Auto rectifier transistor station MAR-APST*****0/6/**0/**0 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*****0/6/**0/**0 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*****0/6/**0/**0 is powered from HV side voltage of 3 kV and 6 kV. Secondary side station produces a voltage **0 V. The voltage is rectified in the 6 diode rectifier to the value of **0 V DC. The output voltage of the automatic transistor rectifier station is unregulated (a constant value).

CONSTRUCTION:

Housing of automatic transistor rectifier station MAR-APST*****0/6/**0/**0 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 disconnectors)

- Security and control chamber, where are protection of the lines, programmable controllers, push s, 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*****0/6/**0/**0 can be placed on a truck equipped with skids or wheels for easy transport station to the place of installation.
