长余辉发光材料在配电网安全标志中的应用

Application of Long Persistence Luminescent Materials in Safety Signs of Distribution Network

安全标志在配电网的运行、维护和检修中发挥着重要的作用,架空线路、电缆、配电设备等的安全指示、警示依靠传统有色油漆的不同工艺形式进行标识,存在夜晚不可见、投运数年后褪色或不明显等问题。针对目前安全标志在配网使用中存在的问题,通过论述长余辉材料的发光机理来论证该材料不会随使用时间的延长而光强减弱,具有明显的耐久性;对长余辉发光材料的制备工艺进行了分析,论述其安全性;并对标志牌价格进行了调查。在此基础上合成长余辉发光粉体,制作了B相相序牌,测试其肉眼可见余晖强度时长。以上研究调查结果表明,长余辉发光材料制作的标志完全适合在配电网中广泛应用。

Safety signs play an important role in the operation,maintenance and overhaul of the distribution network.The safety instructions and warnings of overhead lines,cables,power distribution equipment,etc.rely on the different forms of traditional colored paint for identification,which are invisible at night,faded and not obvious after several years of operation.This article reviews the current problems in the use of safety signs in distribution networks,and discusses the long persistence luminescent to demonstrate that the materials will not weaken the light intensity with the extension of use time,and have obvious durability.The production technology of long afterglow luminescent materials is analyzed and its safety is discussed.And the price of the sign was investigated.On this basis,a long persistence luminescent powder was synthesized,and a B-phase phase sequence brand was produced,and the afterglow intensity time visible to the naked eye was tested.The above research and investigation results show that the signs made of long afterglow luminescent materials are completely suitable for wide application in the distribution network.
