摘　　要：对矿用电机车气动制动系统进行了改进,采用基于无刷直流电机驱动的无油空压机代替传统的注油式空压机,并在前级引入宽范围输入DC/DC隔离电源,可适用不同电压等级的电机车。改进后的气动制动系统无需更换碳刷和加油维护,降低了生产和维护成本。The pneumatic braking system of mine electric locomotive was improved.An oil-free air compressor driven by a brushless DC motor was used instead of a conventional oil-filled air compressor,and a wide-range input DC/DC isolated power supply was introduced at the preceding stage,which can be applied to different voltage level electric locomotive.The modified pneumatic braking system does not need to replace the carbon brush and oiling maintenance,which reduces the production and maintenance costs.
