Abstract:The hospital is a large-scale building with many instruments and equipment and many people. The harm caused by lightning strikes to the hospital is very serious. Therefore, the lightning protection work for the hospital has received more and more attention. The paper analyzes the causes of lightning accidents at a township hospital and then proposes corresponding lightning protection measures, and then combines the characteristics of the surrounding environment of Tongxiang City Women's Hospital and the characteristics of the building itself, according to the "Building Design Guidelines for Lightning Protection" (2010 version). ), "Building Electronic Information System Technical Specifications for Lightning Protection" (2012 Edition) and other related standards, the building will be divided into lightning protection levels, and then for different medical sites, lightning protection design for women's homes, including internal and external lightning protection There are direct-attack, side-thunder lightning protection, shield grounding and other potential connections, and strong and weak power distribution system lightning protection and other aspects of comprehensive consideration and design, in order to avoid or reduce the harm of lightning disasters to women's hospitals and personnel equipment. The paper further introduced the lightning protection measures in the operating room of the Women's Insurance Institute, analyzed the lightning invasion methods and hazards, the distribution system of the operating room, and introduced the equipotential bonding measures of the operating room. Although lightning protection measures cannot completely protect buildings from lightning strikes, certain methods can help reduce the chance of lightning disasters and reduce injuries and losses. Because the characteristics of each building and the environment are different, when designing lightning protection for different buildings, we must design a reasonable lightning protection plan for each building in light of the actual situation in the local area and the real conditions of the building.
