Electrical engineering for mining

BARTEC is the competent partner:

BARTEC offers an array of individual solutions and components in every stage of coal mining: as

single device, for the integration in existing systems or as a complete electro technical system.

BARTEC designs, manufactures and supplies apparatus tailored to customers„specifications for

mobile and stationary mining machinery.

Motors

Due to the specific operating conditions in mining, motors being deployed have to fulfill high demands.

Explosion protected three-phase, asynchronous motors designed by BARTEC according to the

“flameproof enclosure” type of protection provide optimum preconditions for this kind of application.

They are particularly used in mining; gate roads as well as auxiliary ventilated mine openings.

BARTEC mining motors are characterized by their:

high capability at narrow dimensions and sleight weights

low energy consumption due to high efficiency

mechanical strength even under extreme conditions

consistent cooling due to optimized cooling system

We cover the complete performance range required in mining

As well as pole-changing motors in the performance range mentioned above.

All mining motors designed by BARTEC have been approved in accordance with the Directive 94/9/EC

(ATEX)


Automation

Automation of the different operating processes marks far-reaching progress in the mining industry. The

logical advancement is a consistent networking with the end-to-end communication and control concept

developed by BARTEC. On the basis of the Profibus and Ethernet technology, components and complete

systems designed by BARTEC provide an optimum flow of information in the entire mining system – a

milestone in process automation and a new benchmark in mining.

BARTEC provides trend-setting quality for professional automation underground and aboveground. Our

automation technology not only provides central devices but also decentralized peripheral devices for

every case of operation. The intrinsically safe PROFIBUS enables devices to communicate among each

other.

Automation–Peripheral devices

The use of decentralised peripheral devices means taking advantage of the PROFIBUS technology, e.g.

connection between automation device and the dispersedly arranged process devices via one

cable, the field bus

shifting of input and output modules for sensors and actuators to process

processing and transforming of process signals on site

continuous communication from process to control room via field bus

The process device DPM 4 optimises control if digital E/A-peripheral equipment

is used on a big scale.

32 DE/DA-ports which can be set up in groups of four either as intrinsically

safe input with or without supervised cables or as opto-coupler-output via the

PROFIBUS-M. Each activated DE/DA-port is displayed via a LED on the

LED-Board 8SX9012-0DB00. Cable defects at inputs with supervised cables

are displayed by means of flashing.

DA-ports can be connected with up to two relay devices 8SX9012-0BC20 and

with up to 16 relays for the decoupling of external intrinsically safe circuits.

The process device has three interfaces for connection of a quadruple spaced

(à 20 characters) LCD-display as well as two 4x5 plastic foil keyboards for the

features Operate and Observe.


PROFIBUS-M EEx I



Not every automation device can be connected to the

PROFIBUS.

Devices with a serial coupling according to BB 22444 are

widespread in mining.

The peripheral module DPM6 is a gateway for such control

systems and thus allows for the incorporation into complex

automation processes.

Either intrinsically safe or non-intrinsically safe couplers can be

realised.
