High Voltage Electrical Mining Equipment

 

Switchgear KRUV-6(10)E-UHL5

Switchgear KRUV-6(10)E is used to receive and distribute 6/10 kV three-phase, 50 Hz current, to protect isolated neutral networks and control underground current collectors in gas (methane) or coal dust hazardous coal mines. KRUV-6(10)Å is equipped with intrinsically safe remote control circuits, has explosion-proof configuration and explosion protection class Exd[ia]iaI (explosion-proof mining equipment). The casing ensures ingress protection rating IP-54 according to GOST 14254-96.

Explosion-Proof Packaged Transformer Substations

KTPVS substations convert high-voltage 6(10) kV power to low-voltage 1.2 / 0.69 / 0.4 kV and transmits three-phase 50 Hz AC to current collectors mounted in gas (methane) or coal dust hazardous underground workings.

Explosion-Proof Packaged Transformer Substations KTPVS-Rollarc R400

with explosion protection class Exd[ia]iaI (explosion-proof mining equipment) rating from 400 to 1250 kVA and 6 kV are shipped with gas-insulated contactor 'Rollarc R400' and microprocessor unit «Sерам Т40».

Variable Speed Drive CPSS for Underground Mining Applications 

Variable speed drives CPSS-1000/6-0,69-2-UHL 5 or CPSS-1250/6-0,69-2-UHL 5 for mining applications are designed for stepless electric control of the main belt drive with power up to 2õ500 kW and for control of auxiliary belt drives in gas (methane) or coal dust hazardous underground conditions.

Explosion-Proof Distribution Transformer Set TKRV

Explosion-proof distribution transformer set TKRV converts high voltage 6 (10) kV to low voltage 1140 V, 660 V. It transmits three-phase 50 Hz AC to current collectors and protects them from leakage current and provides overcurrent protection for low-voltage lines in gas (methane) or coal dust hazardous underground mines developing sloping and inclined beds.

Variable Speed Drive CPLK for Conveyor Winches

CPLK controls electric drives of the conveyor winch to regulate the belt tension.

Explosion-Proof Variable Speed Drive Station CPSV-500/0.69-UHL 5

Explosion-proof variable speed drive station CPSV-500/0.69-UHL 5 is designed for underground application in gas (methane) and coal dust hazardous workings and provides continuously variable electronic speed and torque control of the conveyor drive, voltage supply to all station and conveyor auxiliaries.

Explosion-Proof Distribution Switching Station VRKS 1.2-6 UHL5

Explosion-proof distribution switching station (VRKS) is designed for underground application in gas (methane) and coal dust hazardous workings and provides power distribution and protection of outgoing electrical networks.
