Description

Technical Field

[0001] The invention relates to the field of power protection, in particular to an insulating installation rod of an insulating sheath of a parallel groove wire clamp and a working method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the power system, the parallel groove wire clamp is a commonly used connection fitting between the main line and the lead wire. In order to ensure the insulation performance of the parallel groove wire clamp and prevent safety accidents such as leakage, short circuit and electric shock, it is necessary to install an insulating sheath on the parallel groove wire clamp.

[0004] The existing buckle structure of the insulating sheath needs to rely on manual operation during installation. The operator needs to buckle the insulating sheath on the parallel groove wire clamp by hand while ensuring his own safety and complying with the live working specifications. Especially in the live working environment, the operator needs to wear insulating gloves, which further increases the difficulty of operation. It is very easy to have problems such as loose buckle or misalignment. At the same time, it leads to low installation efficiency and long time consumption. Long-term live working operation increases the time that power workers are exposed to dangerous environments, posing a greater threat to their personal safety. Summary of the invention
