Problems solved by technology

[0002] In the rush repair operation of the 10kV old-fashioned junction box, in order to ensure the personal safety of the operators, according to the requirements of technical measures, "power outage, power inspection, grounding, hanging signs and installation of barriers must be carried out. The installation of the grounding wire is to ensure the personal safety of the operators Important steps and measures that are essential for safety. According to on-site surveys and statistics, the old-fashioned distribution box takes up a lot of time to check and hang the ground wire, which affects the progress of emergency repairs.

Abstract

The invention discloses a cable terminal grounding wire, which relates to the technical field of high-voltage cable branching cabinet maintenance tools and is structurally characterized in that a through hole is arranged in the middle of a grounding wire contact plate, a hollow contact is sleeved in the through hole in a penetrating manner, internal threads are arranged in the hollow contact, one end is in threaded connection with a screw, and a sleeve further sleeves the hollow contact. One end of the sleeve is connected with an external thread arranged on a protrusion of the ground wire contact plate, an inner bayonet is arranged in the middle of one end of the insulating rod, the inner bayonet is matched with a screw of the hollow contact, and the ground wire is connected with a ground wire clamp. The cable terminal grounding wire has the beneficial effects that when the novel device is used in actual work, rapid, safe and reliable grounding of a cable terminal grounding wire and a cable terminal can be realized; according to the cable terminal grounding wire, the original hanging checking mode of large-area power failure for hanging the grounding wire can be changed in special occasions, so that the occurrence of large-area power failure accidents is avoided, the power supply reliability is guaranteed, and invisible safety benefits are created for enterprises and society.

Description

technical field [0001] The invention relates to the technical field of maintenance tools for high-voltage cable distribution cabinets, in particular to a grounding wire for a cable terminal head. Background technique [0002] In the rush repair operation of the 10kV old-fashioned junction box, in order to ensure the personal safety of the operators, according to the requirements of technical measures, "power outage, power inspection, grounding, hanging signs and installation of barriers must be carried out. The installation of the grounding wire is to ensure the personal safety of the operators Important steps and measures that are essential for safety. According to on-site investigations and statistics, the old-fashioned junction box inspection and connection of grounding wires takes a lot of time, which affects the progress of emergency repairs. Contents of the invention [0003] In view of the above problems, the present invention provides a cable terminal grounding wir...
