Rapid, reliable and safe grounding wire fixture

Abstract

The invention relates to a rapid, reliable and safe grounding wire fixture. The rapid, reliable and safe grounding wire fixture comprises a fixed fixture (1) and a movable fixture (2), wherein a hook (12) is arranged at an upper part of the fixed fixture (1), a sliding rod (21) is arranged at a lower part of the movable fixture (2) and is arranged in a sliding hole of the fixed fixture, a movable fixture head (22) is arranged at an upper end of the sliding rod, a first press spring (25) is arranged in the sliding hole and sleeves the sliding rod, a connection sleeve (4) is arranged below the fixed fixture (1), a plurality of steel ball holes (41) are formed in a side wall of the connection sleeve, a steel ball (42) is arranged in each steel ball hole, an annular steel ball groove (26) is formed in an outer wall of the sliding rod, a control sleeve (5) is arranged below the fixed fixture, and a second press spring (43) is arranged in the control sleeve and sleeves the connection sleeve (4). By using the rapid, reliable and safe grounding wire fixture, reliable contact between the grounding wire fixture and an overhead wire can be ensured, the grounding wire is convenient and rapid to pick up and hang, the power failure maintenance time is favorably shortened, the operation speed is increased, and normal power supply is not affected.

Description

technical field [0001] The invention relates to a power line grounding device, in particular to a grounding line fixture. Background technique [0002] In order to ensure the safety of the staff during the power outage maintenance of the overhead power line, it is required to hang a grounding wire between the power outage operation line and the grounding electrode to prevent accidental power transmission and induction from causing danger to the staff. At present, the grounding wire clamps used in my country's power system mainly have two structures, one is clamped by leaf springs, and the other is clamped by bolts. The defect that the contact effect between the overhead lines is not reliable enough leads to the unreliable connection between the overhead line and the grounding electrode after the grounding wire is hung, and accidents that cause electric shock to the staff due to unreliable grounding will occur, causing unnecessary Danger. In order to avoid the occurrence of d...
