China Supplier Aluminum Oxide Surface Resistivity - Electric Mine Wheel Braking resistor – Wepower

█ Description

The electric drive system of the large mining truck is generally used in the electric drive system, that is, the output power of the diesel engine to the generator. In the vehicle braking, the vehicle’s kinetic energy is transferred to the traction motor by the way of the wheel and the wheel side reducer. The controller controls the output of the inverter, so that the traction motor is working in the state. So we called the mine car braking resistance grid or mining vehicle brake resistance device.

█ Product Features

1. High-power resistor

2. Compact structure

3. Low inductance，good heat dissipation

4. High shock resistance ，high reliability

5. long lifespan

6. Use all kinds of harsh environment

█ Structure

Each brake resistance device is composed of resistance cabinet, the AC axial flow fan and the control circuit. Cooling air enters from the side of the device, and the resistance cabinet is discharged through the axial flow fan, the resistance cabinet, and the end of the other side. Resistance of cabinet in part by the resistance unit, skeleton, seal plate and the connecting copper bar. Each resistor unit mainly by the resistance belt, extraction copper bar, insulating porcelain element and the sheet metal frame resistors value the same interchangeable.
