Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a grounding wire clamp used for a low-voltage line. Background Art

[0002] At present, in the 0.4KV low-voltage line of the distribution network, since this part of the power equipment directly provides power to users and runs through streets and alleys, the probability of users touching it is relatively high compared to voltage lines above 0.4KV. In order to improve the safe operation of the 0.4KV line and avoid personal electric shock casualties, almost all lines are erected or laid with insulated wires. However, when repairing the 0.4KV line, the grounding work of the 0.4KV line troubles the operation and maintenance personnel. According to the relevant regulations of the "two tickets", the maintenance personnel need to wear insulating gloves to strip the insulating rubber layer on the insulated wire to find a place to hang the grounding wire. When performing this process, the staff wear insulating gloves, which affects the flexibility of finger activities and the work efficiency is low. The use of electrician's knife to strip the insulation layer of the wire poses a risk of cutting the wire, reducing the healthy level of the wire operation. At the same time, there is the possibility of users reverse power transmission and personal electric shock casualties, and the safety level is low.

[0003] Although the above problem can be solved by a grounding wire clamp, the existing grounding wire clamp may cause the grounding wire to loosen during use because the stud in the current grounding wire clamp may rotate. Therefore, a grounding wire clamp for a low-voltage line is invented. Utility Model Content
