The invention discloses a railway switch machine contact cover and a working method, and mainly solves the problems of large contact resistance and large rotating resistance of a movable contact caused by abrasion particles, dust, oil stains and the like in the contact area of a movable contact ring and a static contact ring of the conventional railway switch machine. The implementation method comprises the following steps: firstly, cleaning the movable contact of the switch machine by using a movable contact ring self-cleaning system; secondly, using the contact temperature control system for adjusting the temperature of the contact area to prevent condensation; and finally, monitoring the real-time change of the contact resistance through the contact resistance detection device so that the maintenance workload of maintenance personnel on the contact of the switch machine is greatly reduced. According to the railway switch machine contact cover and the working method, the structure is simple, foreign matter in the contact ring area can be cleaned, contact resistance is reduced, moving contact ring disengagement resistance is reduced, contact jamming is prevented, and reliable connection of the contact circuit is guaranteed.
本发明公开了一种铁路转辙机接点罩及工作方法,主要解决目前铁路转辙机因动接点环与静接点环接触区域的磨损颗粒、灰尘、油渍等引起的接点电阻大和动接点转动阻力大的问题。其实现方法是:首先利用动接点环自清洁系统,对转辙机动接点进行清洁;其次利用接点温控系统调节接点区域温度防止凝露;最后通过接点电阻检测装置监控接点电阻实时变化,大幅降低维护人员对转辙机接点的维护与保养工作量。这种铁路转辙机接点罩及工作方法结构简单、能清理自身接点环区域的异物对降低接点电阻、减少动接点环脱出阻力、防止接点卡阻、保证接点电路接通可靠。
