Electrical engineering for explosive applications
Bartec Sicherheits-Schaltanlagen (Bartec), Germany, manufactures internationally-approved switchgear solutions, and electrotechnic and electronic equipment for underground mining applications.
This includes the development, production, supply and installation of explosion-protected:
- Transformers
- Power distribution plants
- Switchgears / control gears
- Mining frequency converters
- Motors for speed-controlled gears
- Automation systems
Power distribution centres
Bartec supplies damp-protected high-voltage three-phase air-transformers in pressure-resistant housing, for equipment power supply in underground mining.
Transformers come with a three or five-wave core, in a low-maintenance, corrugated-pipe boiler, with a junction box designed for both high voltage and low voltage applications. Capacities range from 400kVA to 2,000kVA.
High-voltage components can optionally be combined with a circuit breaker / earthing switch, or a circuit breaker / earthing switch and high voltage contactor. Low voltage components can be combined with a circuit breaker including one or two outgoing feeders.
The centres can also include switchgears / controlgears as draw-out unit, including six pluggable draw-out vacuum-contactors, fuses, protection and control technology, status displays and fault indications.
Mining frequency converters
Bartec also provides fire-damp protected, low-voltage mining frequency converters for speed-controlled drive engineering, for operations in armoured-face conveyors, belt conveyors and coilers.
This equipment can also be used as current source converters for 4Q-operation (drive and brake in both rotating directions) or PWM-inverters for 2Q-operation (drive in both rotating directions). The converters are executed as a compact station for de-central erection.
Converters come with a rated shaft power of between 250kW and 500kW, BdD type for 4Q operation; or between 90kW and 630kW, VSD type for 2Q operation, and have a nominal voltage of 3AC1kV or maximal 1,14kV.
Bartec converters include intrinsically safe PROFIBUS-DP-AM (ATEX mining) and FSK-modulation data transmission, and frequency or speed regulation and torque control, with or without speed feedback.
Three-phase motors for undergound mining machinery
Bartec manufactures low-voltage three-phase motors for underground mining applications, including models with a rated voltage of up to 3AC 1,140V, an air-cooled engine output of between 0,25kW and 400kW. Models with a rated voltage of up to 3AC 1,140V are also produced, with a water-cooled engine output of 90kW up to 630kW.
Bartec also manufactures these low-voltage motors as special motors for frequency converter operations of up to 630kW, fans and mining machines, as well as equipment with powerful drives of up to 800kW.
A high-voltage three-phase motor is also produced, with an engine output of between 300kW and 1,800kW, a rated voltage of 3AC 3, 3kV up to 6kV, and is air or water-cooled.
Mining automation, net protecting modules, components and accessories
Bartec also designs, manufactures and supplies the following components and accessories:
- Damp-protected mining controller with ETX-Board, CPU-Modul, communication modules
- IKS-mini control system for integration in explosion protected housings with PROFIBUS and CANopen-devices
- Decentral process modules (PROFIBUS AM-Ex, CANOpen Am-Ex) for connection with mining controllers or IKS-mini control systems
- Module power supplies (single and multiple-power)
- System components, interface components, signal former modules
- Terminal boxes with a steel-plate housing
- Polyester junction boxes for fibre optics
- Net-protecting components, including overload relays, isolation and SL-components, earth-leaking relays, PTC resistor trip relays
- I/O-systems including a PROFIBUS-device, Ethernet-network distributor with fibre optics net
- Network cameras with integrated web-server for network connection
- LED lights for longwall lights or head lamps
Bartec equipment is manufactured in compliance with QM – certificates DIN ISO 9001, ATEX 100a and IECEx.
