Abstract

The invention relates to a high-voltage cable head grounding device which comprises a grounding rod and a grounding seat. A bolt component is arranged on the grounding seat, an upper connecting ring is arranged at the top end of the grounding rod, a lower slider is arranged on the grounding rod, a connecting hole is formed between the upper connecting ring and the lower slider, and an adjusting component is arranged on the grounding seat. The high-voltage cable head grounding device has the advantages that the grounding device is directly arranged on a high-voltage cable head through a connecting column, grounding protection of operators can be achieved when wires on the cable head are disassembled by the operators, working safety is ensured, falling off of the grounding device can be prevented, the grounding device can be rapidly and fixedly mounted, a grounding wire is connected on the grounding seat through the bolt component, so that the grounding wire is fastened through the bolt component, the grounding device is firm to mount and simple and convenient to operate, the adjusting component adjusts the lower slider to move on the grounding rod, and the size of the connecting hole between the upper connecting ring and the lower slider is adjusted, so that the connecting hole adapts different sizes of wires or electric conductor and high in universality.

Description

technical field [0001] The invention relates to a grounding device for a high-voltage cable head. Background technique [0002] 110kV spaced cable outlets, when the cable connector needs to be removed for the voltage change arrester test, due to the limitation of the shape and structure of the grounding device, the existing grounding wire cannot be hung at the cable head, so the grounding wire on the line side is hung on the line side of the line switch knife , at the moment when the cable joint is disconnected, the cable head loses the protection of the ground wire and there will be a high induced voltage, which is very easy to cause people to accidentally touch the live parts. At present, the safety measures taken to implement this work are: The annealed copper wire of the high-level test will short-circuit the three phases, and then install a conventional grounding wire on the annealed copper wire to meet the requirements of equipment grounding. Such a traditional test me...
