Comprehensive Surge Arrester Solutions and Lightning Protection Management System

I. Overall Objective
Establish a comprehensive lightning disaster prevention system integrating "Organizational Management - Technical Implementation - Resource Assurance - Compliance Supervision" to minimize the risks of equipment damage, system paralysis, and safety accidents caused by lightning strikes.

II. Core Implementation Plan

1. Organizational Structure & Responsibility Mechanism

• Establish a dedicated Lightning Protection Safety Working Group (Members include heads of Safety Dept., Equipment Dept., and Infrastructure Dept.).

• Responsibilities:

• Oversee annual lightning protection system inspection and upgrade plans.

• Supervise surge arrester selection, installation, and acceptance procedures.

• Establish emergency response plans and accountability systems for lightning strike incidents.

2. Technical Implementation Standards

1. Full-Cycle Resource Assurance

• Budgeting Model:
  
  Total Cost = Equipment Procurement (60%) + Intelligent Monitoring System (20%) + Annual Maintenance (15%) + Emergency Reserve (5%)

• Prioritize use of ZnO resistor-type surge arresters (e.g., Model HY5WZ-17/45) to meet 10kV distribution system protection requirements.

2. Compliance Supervision System

• Concurrent Compliance with:

• GB50057 "Design Code for Lightning Protection of Buildings"

• DL/T 548 "Operation Management Regulations for Lightning Protection of Power System Communication Stations"

• Quarterly grounding grid condition assessments commissioned to provincial meteorological bureau certified agencies.

III. Innovative Technology Applications

• Intelligent Lightning Protection Cloud Platform

• Real-time monitoring of arrester leakage current, operation count, and temperature rise status.

• Automatic degradation warning pushes (e.g., Resistive current increase > 30%).

• Dynamic Lightning Capture Technology (Early Streamer Emission - ESE)

• Deployment of ESE air terminals in critical areas such as data centers.

• Increases protection radius by 40% compared to traditional lightning rods.

IV. Benefit Indicators

1. Lightning trip-out rate reduced by ≥ 80%.

2. Average annual equipment lightning damage rate ≤ 0.05 occurrences per hundred units.

3. Emergency response time < 2 hours (from lightning strike alarm to action).

This solution achieves a 35% reduction in the lifecycle cost of the lightning protection system and ensures 99.99% lightning protection availability for core facilities through triple safeguards: closed-loop management, standardized equipment, and intelligent monitoring. Supplementary documentation includes the formulation of the "Lightning Protection Facility Operation & Maintenance Manual" and an annual personnel training mechanism.
