FIELD: electricity.
SUBSTANCE: invention relates to portable devices of current-conducting connections and is intended to provide grounding of direct and alternating current catenary system of electrified railways during repair and service works. Portable earthing device comprises, connected by means of a grounding wire, a grounding shoe and a split bar, a locking key configured to secure the grounding shoe between the lower surface of the rail head and the fastener of the rail to the sleeper, comprises a hinge equipped with a torsion spring, which provides the contact part pressing to the lower surface of the rail head, wherein the hinge is configured to move the contact part in the axial direction for all standard sizes of rails and sleepers, the thrust tooth is configured to rest the locking screw to prevent the grounding shoe from dropping, locking key is arranged with the possibility of cable head fixation, besides, left-hand thread is made on fixing screw, and spiral is made in phase clamp.
EFFECT: higher reliability of contact between portable grounding device and rail.
