建筑工地施工用电,因开发规模、场地、周边环境等多重相关因素影响,所采取具体措施也不尽相同,但原则上所采取常用设备、防范要求等大致相似。在施工前期要做好临时用电设备的负荷计算,根据现场情况,合理分配用电荷载。文章主要介绍了设计时负荷的计算方式和运行时遇到的故障实例及解决措施。 Construction site construction electricity, due to the development scale, site, the surrounding environment and other relevant factors, the specific measures taken are not the same, but in principle to take common equipment, prevention requirements are similar. In the early construction of temporary electrical equipment to do the load calculation, according to the scene, the rational distribution of electricity load. The paper mainly introduces the calculation method of load at design time and examples of failures encountered during operation and their solutions.
