通过电化铁路的不断开通和长期运行,由于接触网零部件防松脱措施不全面而引发的故障居高不下,在接触网设备质量的验收过程中也不断发现;对接触网零部件防松脱措施进行研究,把控验收重点,减少设备故障,指导车间采取合理零部件防松脱预防措施。 Due to the continuous opening and long-term operation of the railway, the high failure caused by the inadequate anti-loosening of the catenary components has also been found during the inspection of the quality of the catenary equipment. The catenary components are not loosened Measures to carry out research, control and inspection focus, reduce equipment failure, guide the workshop to take reasonable precautions to prevent loosening of parts.
