摘　　要：转辙机的排布式接点在现场复杂多变的使用环境中会出现接点磨损的现象,导致动接点脱出困难,最终造成接点缓打或卡阻。针对该现场引发的问题,首先,从接点片磨损原因进行理论分析;其次,通过试验验证与接点磨损强相关的因素;最后,通过借鉴高压运输行业广泛应用的电力复合脂工程化经验,结合转辙机使用工况,开展常温、低温试验研究,得出电力复合脂对于转辙机接点磨损有着较为明显改善的结论,为提升转辙机接点的使用寿命、降低转辙机卡阻概率提供了思路和经验。The complex and changeable environment will cause contact wear of the arranged contacts of the switch machine on site,which will lead to the difficulty of moving contacts to come out,and eventually cause the contacts to slow down or be jammed.In view of the problems on site,firstly,the theoretical analysis was carried out from the causes of contact wear;Secondly,the factors strongly related to contact wear were verified through experiments;Finally,by drawing on the engineering application cases of electric composite grease which widely used in the high-voltage transportation industry,combined with the working conditions of the switch machine,the experimental research of normal temperature and low temperature was carried out,and the conclusion that the electric composite grease has a relatively obvious improvement on the wear of the contact of the switch machine was obtained,which provided ideas and experience for improving the service life of the contacts of the switch machine and reducing the probability of jamming of the switch machine.
