摘要： A method of lubrication of a buffering device of an operating mechanism of a switchgear, comprising:arranging a lubricating plug at an end of an internal cylinder of the buffering device; having a flow path in an interior of said lubricating plug, said lubricating plug being connected with a conduit; fixing a packing in a vicinity of a tip of said lubricating plug; bifurcating said conduit into two branches; connecting one of said conduits with a vacuum pump; connecting another of said conduits with a container that accumulates said operating fluid; arranging a first valve on a vacuum pump side of said conduit; arranging a second valve on a container side of said conduit; when said operating fluid is introduced into an interior of said buffering device, said second valve is closed, said first valve is opened, and an interior of said buffering device is thereby put beforehand into a vacuum condition by said vacuum pump; and, in addition, lubrication of said interior of said buffering device with said operating fluid within said container is effected by closing said first valve and opening said second valve.
