低压动力照明设备在地铁内分布广泛,据统计,照明和导向标识故障占到低压动力照明设备故障总数的80%以上。南京地铁通过对1号线照明和导向标识系统进行合理的技术改造,达到延长灯具使用寿命、减少检修成本、提高工人检修时的安全保障、节约电能、降低故障影响范围的目的,保障了地铁运营安全。
Low-voltage power lighting equipment in the subway widely distributed, according to statistics, lighting and directional identification failure accounted for more than 80% of the total number of low-voltage power lighting equipment failure. Nanjing Subway through the line 1 lighting and directional identification system for reasonable technical transformation, to extend the service life of lamps and lanterns, reduce maintenance costs, improve worker safety inspection overhaul, save electricity, reduce the scope of the failure of the purpose of safeguarding the subway operation Safety.
