调压开关机械联锁弹簧由于原设计和制造工艺都存在一定的问题,在运行中曾多次发生断裂现象,致使机械联锁的杆卡在主凸轮轴上圆盘的缺口内,造成分级转换开关无法转换。如果不能及时处理,就会造成机破事故。因而在1982年12月召开的铁道部西安电器工作会议上被列为五大电器可靠性攻关任务中调压开关可靠性攻关项目的主要内容
Pressure switch mechanical interlocking spring due to the original design and manufacturing process there are some problems in the operation has repeatedly broken phenomenon, resulting in mechanical interlocking card stuck in the gap on the main camshaft disc, resulting in hierarchical conversion Switch can not be converted. If you can not handle it promptly, it will cause the machine to crash. Therefore, in December 1982 held in the Ministry of Railways Xi’an electrical work conference was listed as the five major electrical reliability research tasks in the reliability of the main switch pressure switch project
