HRVS-DN in Explosion-Proof Cabinets at the MIR Diamond Mine, Russia

Mining and controlling water pumps

MIR Diamond Mine

Product: HRVS-DN
Motor Ratings:
6kV, 140A

OJSC ALROSA, a worldwide leader in diamond mining, approved Solcon's HRVS-DN Medium Voltage Soft Starter to be commissioned in the MIR underground mine.

Water pumps 210 meters below the surface of the mine required a starting solution that could overcome the voltage drop and the risk of Water Hammer. In addition, the entire starting system had to adhere to both Russian Mining criteria* and Alrosa's standards.

MIR Diamond Mine Russia The HRVS-DN, Solcon's Medium Voltage Soft Starter, was selected for this project. Five custom made units (6kV, 140A) were installed in explosion proof cabinets according to the electrical and mechanical requirements of the mine. Solcon's Partner in Russia TK BIC Ltd designed and commissioned the project based on the space limitations and the data from the pumps' motors. Each HRVS-DN unit was pre-configured using an algorithm running on an explosion proof Programmable Logic Controller (PLC) via integrated HMI console.

Solcon has been producing soft starters for over 30 years and has gained a great deal of experience with water and mining applications worldwide. Solcon's HRVS-DN Medium Voltage Soft Starter offers a tailor made design manufactured according to international standards and specific customer requirements. It provides superior control of current and voltage during motor start and stop as well as a comprehensive motor protection package. Pump Control, specific feature designed for pumping applications, enables selection between three voltage ramp-down curves or a torque curve preventing stall conditions and eliminating Water Hammer damage.
