摘　　要：室内海洋馆水质复杂,需要借助较多维生机房循环改善水质,维持水体各类成分平衡及调节水温。维生系统设备多,用电负荷大,动力配电系统庞大。由于室内海洋馆遍布大小水池,湿度较大,蒸汽中含盐分等密度高,水质为碱性,对金属管线腐蚀性较强,普通镀锌钢板喷塑桥架易受到碱性蒸汽影响,发生电化学腐蚀,对运营造成较大安全隐患。选用PVC阻燃合金桥架可满足强度要求、防火要求,且材料绝缘,不会发生漏电危险,无须安装跨接线,并因其耐腐蚀性能,材料的应用不受环境影响,满足现场要求,可提高使用安全系数。The water quality of indoor aquariums is complex,and more life-saving machine room cycles are needed to improve the water quality,maintain the balance of various components in the water body and adjust the water temperature.There are a lot of life-saving system equipment,heavy power load,and huge power distribution system.Due to the large and small pools in the indoor aquarium,the humidity is relatively high,the salt content in the steam is high,and the water quality is alkaline,which is relatively corrosive to metal pipelines.The ordinary galvanized steel plate sprayed plastic bridge is susceptible to the influence of alkaline steam and generates electricity.Chemical corrosion causes greater safety hazards to operations.The use of PVC flame-retardant alloy bridge can meet the requirements of strength and fire protection,and the material is insulated,and there will be no leakage risk.There is no need to install jumpers.Because of its corrosion resistance,the application of materials is not affected by the environment.Meet the site requirements and improve the safety factor.
