is one of the practical form of values. The so-called values refers to the objective things are of no value and the value of fundamental perspective. Different values, people's behaviour, attitudes, ways are different. People-oriented focus on human value and reality, we need the broadest masses as values. Adhere to people-oriented values, is to make the economy more development, improve democracy, cultural prosperity, and live a happier; is deeply concerned that human development and human values, development of social and human development of rational unified, insisted in the material civilization, political civilization and spiritual civilization in the overall advancement of Socialist civilization to a higher level. Also want to see that person's value is not only meet your needs, also is to meet the needs of others and the community. Adhere to people-oriented, to strongly advocate every community member, serve others, beneficial to the community of people. The so-called Outlook, attitude is on the record, including who, how to create a record of achievements, how to evaluate performance, and so on. What values, what kind of Outlook. Adhere to people-oriented Outlook, is on the premise of respecting the interests and power of people, creating a popular, warm hearts, steady heart performance, creating \ements, and overall construction of well-off society and promoting the all-round development of people's performance.

1、本工程临时施工用电的特点

临时用电工程区别于“永久性”用电和工程，是专门的建筑施工需要提供电力的电气工程。根据现场勘察情况，本工程具有下述特点：

（1）暂设性或临时性。施工现场临时用电工程专为现场建筑施工使用，随着建筑工地的竣工，该临时供电系统将予以拆除。

（2）移动性或流动性。由于建筑施工和施工用电设备随着建筑位置变化而移动，因而该临电工程的全部或局部亦将随之迁移或流动。

（3）露天性。建筑施工通常是露天作业，因此为提供电力的临时用电工程基本上属于露天电气工程。

（4）地理位置。自然条件不选择性，临时用电工程地理位置和自然条件由于建筑工程所处地理位置和自然条件决定，不可人为地另行选择。

三、施工临时用电设计

1、临时用电施工部署

根据《施工现场临时用电安全技术规JGJ46-2005》要求，同时结合建设提供的施工用电接入点和拟建工程的分散性，我司项目部对临时用电的总体规划：从施工临时用电接入点的总配电箱设置输电电缆干线供电，在接入点处设一个总配电箱（一级配电箱）。配电模式按三级配电即：总配电箱（一级）至分配电箱（二级），分配电箱至开关箱（三级）的线路供电模式。开关箱至施工用电设备全部采用绝缘双胶电线。根据场地条件，用电干线采用套管埋地设置，部分利用现有墙体采用架空设置，架空高度必须有关规规定要求。所有
