Transformer Station Martb For Underground Applications - Poland

Transformer station type MARTB.

degree of protection IP54

Transformer Station MARTB PM is designed to supply

electrical machinery and equipment working in underground

mines adapted for use in non-hazardous excavation or non-

hazardous methane and classified to "A" class of coal dust

explosion hazard.

Transformer Station MARTB-type .

PM

consists of a power transformer and apparatus for switching

and protective placed in a common housing with degree of

protection IP 54, which is equipped with skids or wheels.

Transformer Station MARTB-type .

PM is powered by high

voltage side voltage up to 6 kV.

Secondary side station

produces a voltage 525 V and 1050 V (400 V to 1140 V).

You

can adjust the voltage of station up to 5% by changing the

transformation ratio.

Ratio adjustment is on the HV side of

the station de-energized.

The station uses a microprocessor

relays PM which provide protection against short-circuits ,

asymmetry overload and damage earth insulation outflow.

In

addition, microprocessor relays type PM are equipped with

the security element to exceed

the allowable temperature in winding power transformer for

the class of insulation, the continuity of the ground

control element, the control systems and the local and

remote and systems to display information about the status

of the stations and emergency situations.

Construction

Housing type transformer station MARTB-.

PM has been made

in the form of frame construction, welded sheet metal bent

profiles thickness of 3 mm.

The housing has IP54 protection.

Housing is divided into the following compartments:

- HV chamber with earthing switch,

- chamber transformer (power and auxiliary)

- LV chamber apparatus,

- circuit breaker chamber or chamber contactor (contactors)

- chamber of security and control where is control panel

with microprocessor relays 1K1 ÷ 4K1, central leakage

protection, the buttons for controlling the station and

voltmeter,

- Optional, chamber of security and control may include a

digital relay PM ., which is used to protect against

overloads, short circuits and leakage controls the output

circuit voltage 24 V AC to 230 V AC.

Doors and covers of chambers are made of sheet metal with

internal stiffeners welded.

The door is equipped with hinges

and locks type baskvil , and sealed with rubber gaskets,

glued on the inside.

The door of the chamber of transformers

used filters (optional), which is drawn by the fan

(optional) air to cool the power transformer.

The upper cover is equipped with 3 filters with suction fan

(optional) to exhaust heat generated by the transformer

during operation.

LV chamber apparatus is equipped with an

electric lock, causing the power supply off the electrical

system at the station opened the door of the chamber.

HV

chamber door switch and transformer

chamber door is equipped with a mechanical stop that

prevents them from being opened if the HV station switch is

in the attached.

Chamber of disconnector has a sight glass

through which you can observe the position of disconnector

contacts.
