据统计,在建筑物内发生的火灾中,由电气引起的火灾的比例很高,也就是说电气火灾发生概率高,问题较为突出。这个问题给人类生活造成了极大影响,甚至造成不可挽回的后果。因此提出合理有效的消防用电设备及供配电的设计方案,降低电气火灾发生几率具有重要意义。 According to statistics, there is a high proportion of fires caused by electrical fires in buildings. In other words, the probability of occurrence of electrical fires is high, and the problems are more prominent. This issue has had a tremendous impact on human life and has even irreparable consequences. Therefore, it is of great importance to propose a reasonable and effective fire-fighting power equipment and design scheme for power distribution to reduce the risk of electrical fire.
