The invention relates to a brake resistor method for improving the reliability of a locomotive, which is characterized in that a plurality of traction motors, a plurality of brake resistor loops and a fan (9) are included, and each traction motor corresponds to one brake resistor loop to form a loop; the fan (9) takes electricity on the resistance loop, and the fan (9) generates cooling air to cool the brake resistor unit (2) formed by all the brake resistor loops; the braking resistor unit (2) comprises a group of a plurality of isolating switches, so that the fan (9) can be switched among a plurality of resistor loops; when the traction motor does not have a fault, the fan (9) is connected in parallel to one of the resistance loops and normally takes electricity to provide cooling air for the braking resistance unit (2), the resistance braking function of the locomotive is normal, the reliability of the resistance braking function is improved, and when one traction motor has a fault, the resistance braking function fault of the whole locomotive cannot be caused.
本发明涉及一种提高机车可靠度的制动电阻方法,其特征是:包含多个牵引电机、多个制动电阻回路、风机(9),其中每个牵引电机与一个制动电阻回路对应,构成一个回路;风机(9)在电阻回路上取电,风机(9)生成冷却空气为所有制动电阻回路构成的制动电阻单元(2)降温;制动电阻单元(2)包含一组若干个隔离开关,可以让风机(9)在多个电阻回路间切换;当牵引电机没有故障时,风机(9)并联在其中一个电阻回路上,正常取电为制动电阻单元(2)提供冷却空气,机车电阻制动功能正常,提高电阻制动功能可靠度,能在一个牵引电机故障时,不会导致整个机车的电阻制动功能故障。
