太原机务段:特性控制插件“起死回生”

2017-08-21 18:57:04   央广网

央广网太原8月21日消息(记者李楠 通讯员张秋生)“暑运以来,我们能自己修复韶山4型机车电子柜特性控制插件,使其起死回生,既降低了维修成本又保证了机车质量。”8月,太原机务段“梁计元先进创新工作室”负责人梁计元说到。

据了解,该段有170台韶山4型机车,主要承担石太线、北同蒲线等线路的货物运输。特性控制插件是韶山4型机车电子柜上主要电子插件,其功能主要是控制机车牵引电流,一旦损坏,将引起机车单节无电流或全车无电流。

过去,特性控制插件发生故障,只能对其进行更换新品,结果累积下大量的故障插件。

梁计元看在眼里,急在心上,与工作室技术骨干积极开展技术攻关。在太北检修车间电子组工长王锐的协助下,他们对故障特性控制插件利用万用表及电容表测量每条电路、电阻、电容,经过梳理、分析,发现大部分故障是由于两个电阻、一个电容烧毁或阻值发生变化造成的。随后,他们到电子市场上购买回相同型号的电阻、电容,对其进行更换,通过电子柜插件试验台测试,符合工艺要求,再经验收员检验后上车试用,能够达到原来的性能,完全符合技术要求。

王锐高兴地说:“一块新特性控制插件为6000余元,更换两个电阻及一个电容只需25元。目前,我们已修复30块,节约成本18万元。”
