High Voltage Reverser RVVSh-6-400-U3 for Efficient Mining Operations

Reverser high-voltage type RVVsh-6-400 is designed to control the electric drive of mine hoisting installations with voltage of 6 kV three-phase current frequency of 50 Hz, not exposed to atmospheric overvoltages or in installations with appropriate lightning protection means.

The reverser performs reversing of the electric motor, as well as dynamic braking of the electric motor stator by direct current (from an external source). The dynamic braking current is controlled by means of an ammeter mounted on the cabinet door.
