1概述排油注氮灭火装置不需水泵水池等配套设施,经济简便,日常维护费用低,不受冰冻影响,长期使用无阻塞,广泛适应于各类油浸式变压器及贮油罐防火保护,尤其适用于缺水、高寒、风沙大等环境恶劣地区和一些变压器改造项目中。(1)目前,市场上用于保护油浸式变压器的排油注氮灭火装置存在着以下不足。①排油电磁机构采用敞开方式,容易受人为误动和人为破坏。②排油电磁
1 Overview Discharging oil nitrogen fire extinguishing devices do not need pumps and other ancillary facilities facilities, economic simple, low maintenance costs, free from the impact of freezing, long-term use of non-blocking, widely used in various types of oil-immersed transformers and fuel tank fire protection, Especially for water shortage, alpine, sand and other harsh environment and some transformer transformation projects. (1) At present, the following deficiencies exist in the market for oil discharge nitrogen injection fire extinguishing devices for protecting oil-immersed transformers. ① Exhaust electromagnetic mechanism adopts open way, easy to be human misoperation and man-made damage. ② oil discharge electromagnetic
