ELECTRIC LOCOMOTIVEVERTICAL TYPE DBR

This is highly compact braking resistor. The resistor is divided into resistor bank, 3 phase induction motor and blower. Resistor bank consist of six resistor tiers connected to six traction motor. Resistor banks are made from nickel chromium alloys capable to withstand high temperature with low tendency of aging, low resistance change and long life. Blower is axial flow fan with AC motor (DC motor optional). Blower is aluminium alloy die cast. Blower fixed on the bottom of the underframe and fresh air is sucked in from the lower portion. Top of the resistor bank is matched to the roof of the locomotive and hot air is blown out from the roof top into the atmosphere. This type of braking resistor is highly successful and provided maximum braking efforts helping to reduce speed of the train with loads up to 4800 ton.

• Independent AC three phase blower motor is fed separately hence, almost constant airflow (quantity + velocity) over the grids is available throughout the entire range of braking current which results in low temperature rise of DBR.

• Maintenance cost of AC three phase motor is substantially less as compared to DC Motor.

• Better braking effort.
