Before Replacing The High-voltage Disconnect Switch, It Is Necessary To Confirm That The Construction Organization Plan Has Been Implemented Effectively.

Before undertaking the replacement of line high voltage isolator, a comprehensive construction organization plan must be implemented, including all aspects such as construction arrangements, personnel allocation, work procedures, safety measures, and supervisory responsibilities. The plan should cover power outage applications, site inspections, environmental assessments, tool and equipment configuration, personnel qualifications and division of labor, and emergency response plans.

Before construction, a request for line shutdown or power cut-off should be submitted, and a safety inspection of the site and surrounding environment should be conducted. For lines under load, a thorough assessment of weather conditions and the movement of people and vehicles in the vicinity should be performed before replacing line high voltage isolator switch to minimize operational risks.

Workers must wear qualified insulated tools and protective equipment. A strict supervisory system must be implemented during operation, with one person operating and another supervising. The name and number of line hv isolator must be verified on-site, and the equipment location must be carefully checked against the number to confirm the actual open/closed state of the stationary and moving contacts.

The mechanical installation process must comply with construction specifications regarding hoisting, load traction, tool positioning, locking, and grounding measures. After installation, line hv isolator switch should be placed in the disconnected state and locked to prevent accidental closure.
