Handling Plan for Insulator Damage Constituting Severe or Critical Defects

Insulators are critical components in power systems, primarily used to support and secure conductors while providing insulation and preventing short circuits. Damage to an insulator can lead to serious issues within the power system, potentially endangering personnel lives and property safety. Therefore, timely handling of insulator damage and the formulation of corresponding emergency response plans is essential. Below is a handling plan for insulator damage constituting severe or critical defects, designed to ensure the safe and stable operation of the power system.

1. ​Accident Background and Objectives:​​
   • To promptly address severe or critical defects caused by insulator damage, ensuring the safe and stable operation of the power system, and safeguarding personnel lives and property safety.
2. ​Emergency Response Procedures:​​
   • ​Step One: Discovery of Insulator Damage​
     • Distribution line operators, maintenance personnel, and patrollers shall conduct regular inspections of insulator conditions. Upon discovering damage, they must immediately report to superiors.
     • During inspections, focus on whether there are obvious surface damages, cracks, or detachment on the insulator. If found, personnel shall evacuate the area to ensure safety and prevent casualties.
   • ​Step Two: Activate Emergency Response Mechanism​
     • The operator on duty shall immediately report the insulator damage situation to superiors or the emergency commander and activate the emergency response mechanism.
     • Superiors or the emergency commander shall immediately mobilize relevant personnel to arrive at the accident site and commence on-site handling.
   • ​Step Three: On-site Handling​
     • Ensure site safety by setting up warning signs and cordoning off the area to prevent unauthorized access to the damaged insulator.
     • Further investigate the cause of the insulator damage and implement measures to limit potential hazards arising from the damaged insulator.
     • If the insulator is severely damaged, potentially causing line outages or triggering other equipment failures, initiate temporary isolation and switch to backup equipment to ensure system stability.
   • ​Step Four: Repair and Restoration​
     • Based on the severity of the insulator damage, formulate a specific repair plan and mobilize the necessary personnel and materials.
     • Repair or replace the damaged insulator, ensuring it can properly support and secure the conductor and possesses good insulating performance.
     • During repairs, maintain good coordination with other equipment to avoid impacting system operation.
   • ​Step Five: Accident Analysis and Improvement Measures​
     • After completing repairs, conduct a comprehensive analysis and assessment of the accident to identify the causes and lessons learned regarding the insulator damage.
     • Based on the analysis results, propose improvement and preventative measures to avoid the recurrence of insulator damage issues.

3. ​First Aid Measures:​​
   • If an electric shock occurs at the site, immediately dial the emergency rescue number and perform CPR (Cardiopulmonary Resuscitation) and other first aid measures. Simultaneously, ensure site safety to prevent secondary electric shocks.
4. ​Emergency Communication and Resources:​​
   • Establish an emergency communication system at the incident site to ensure effective communication among all units and personnel, enabling timely updates on the latest situation.
   • Organize and coordinate relevant resources (e.g., personnel, equipment, materials) to support smooth on-site handling and repair work.
5. ​Emergency Drills and Training:​​
   • Regularly organize emergency drills and training to enhance the response capabilities and skill levels for handling insulator damage.
   • During drills, emphasize fostering seamless coordination and optimizing workflow to ensure the efficiency and effectiveness of the response to insulator damage accidents.

By implementing this emergency handling plan, rapid response and swift action can be taken upon the occurrence of insulator damage, minimizing the impact and losses resulting from power system failures. Concurrently, continuously improve and refine the emergency plan to ensure its adaptability to various complex and changing situations, and elevate emergency response capabilities and standards.
