矿区地面变电所防灭火技术创新应用研究

Research on innovative application of fire prevention and extinguishing technology in ground Electrical substation of mining area

电气火灾作为各类火灾中危害性最大之一,每年约占总火灾的30%。而在所有的电气火灾中,因变电站中含有的可燃设备是所有电力系统中最多的,故70%多的火灾发生在变电站。作为电力传输的重要载体和高电压危险场所,变电站一旦其发生火灾事故,往往导致设备烧损、故障跳闸,难以扑救,造成电力中断还易造成巨大的关联安全事故以及生产损失。本文对矿区地面的变电所防灭火技术进行探讨,并展望其实际应用前景。

As one of the most harmful fires,electrical fires account for about 30%of the total fires every year.In all electrical fires,more than 70%of the fires occur in substations because the combustible equipment contained in substations is the largest among all power systems.As an important carrier of power transmission and a high voltage dangerous place,once a fire accident occurs in a substation,it often leads to equipment burning and fault tripping,which is difficult to put out,and it is also easy to cause huge associated safety accidents and production losses when power interruption is caused.This paper discusses the fire prevention and extinguishing technology of the ground substation in the mining area,and looks forward to its practical application prospects.
