摘要
以某工程的伞形灯光秀构筑物群为例,介绍其配电和控制设计的要点及解决措施:分析末端保护电气的类型及特性与最大供电距离的关系,解决末端保护电器的电击安全防护问题;校验供电半径和线缆截面积,以避免电压偏差对照明质量的影响;根据构筑单体钢结构特点及灯具设置特点,合理设计防雷与接地措施和系统接地型式;实时监测每条配电回路的电流、电压状态,保障电源供电;采用具有电源监测和灯光控制功能的总控管理平台实现灯具多彩、多情景、交互的照明效果。
Taking the umbrella light tshow structure complex project as an example,this article introduces the key points of its power distribution and control design and solutions:to analyze the relationship between the type and characteristics of end-protection appliances and the maximum power supply distance,and solve the problem of electric shock safety protection for end-protection appliances;calibrate the power supply radius and cable cross-sectional area to avoid the impact of voltage deviation on the lighting quality;reasonably design lightning protection and grounding measures and system grounding type according to the characteristics of the steel structure of the structure monolith and the characteristics of the luminaire settings;monitor the current and voltage status of each distribution circuit in real time to guarantee the power supply;and use a general control management platform with power monitoring and light control features to achieve colorful,multi-scenario,and interactive lighting effects of the luminaire.
