和谐型机车制动系统运用操作的探讨与实践

Discussion and Practice on Brake System Operation of HX-type Locomotives

和谐型大功率交流传动机车普遍采用了基于微处理器和Lon网的电空控制系统的CCBⅡ制动系统或DK-2型制动系统,其运用操作理念与传统的DK-1型制动机差异较大。从和谐型机车制动系统设计理念、操作规范及故障判断处理方面出发,深入分析运用现场对制动系统运用操作存在的误区和问题,通过实践探索取得了良好效果。

CCBII-type brake system and DK-2-type brake system based on the microprocessor and LON-network electro-pneumatic con trol are generally used in HX-type high power AC drive locomotives, and the operation principles are largely different from the tradi tional DK-l-type brake. From the de.sign concept, operation specification, fault diagnosis and processing of the HX-type locomotives＇ brake systems, this paper thoroughly analyzes the misunderstanding and problem to the brake system operation from the operation scene, and the good effect is obtained through the exploration practice.
