Description

Technical field: [0001] The invention relates to a box-packed portable telescopic grounding operation rod, which is a tool for the on-site grounding wire of construction personnel in power supply enterprises, and is specifically used in the construction and maintenance of lines and substations. It is used to ensure safety in case of electrostatic induction electric shock or false closing. Background technique: [0002] The grounding wire is the lifeline to ensure the safe operation of electric construction personnel on site. In recent years, with the intensification of power grid transmission, distribution, and transformation project construction and technical transformation, especially the increasing operation and maintenance of power grid line equipment, technical measures to ensure safety must be taken during on-site maintenance operations, one of which is The first item is to ensure the personal safety of the maintenance personnel during operation by installing a ground...

AI Technical Summary

Problems solved by technology

Due to the long length of the operating rod and being exposed outdoors, it is inconvenient to transport during daily maintenance and transportation, and bumps are inevitable, which will cause damage to the insulation of the operating rod to varying degrees. Once the insulation value does not reach the national standard Requirements, will most likely bring direct harm to construction workers
