Abstract:With the integrated construction of drainage project,electrical facilities for water utilities are more diversified,which puts forward higher standards for electrical design in drainage engineering. Through analysis of common problems in design,streamlining the electrical mandatory provisions. By means of examples of design,analyzing the power load classification and selection of transformer operation mode for sewage facilities of different scales,as well as the common schemes,principles and cautions for drawing review of quantities and locations of substations and distribution rooms in the wastewater treatment plant,to provide reference for the technical personnel engaged in electrical design of relevant fields.
Key words:drainage engineering;electrical design;wastewater treatment plant;mandatory provisions;load classification;transformer operation mode;transformer capacity;municipal drawing review
摘 要:随着排水工程的一体化建设,水务用电设施更加多样化,对排水工程中电气专业设计提出了更高的要求,通过对设计中常见问题的分析,梳理电气强制性条款,通过设计实例分析不同规模污水设施的用电负荷分级及变压器运行方式的选择,污水厂内变电所及配电间的设置数量及位置的常见方案、原则及图审注意事项,供从事相关领域工程电气设计的技术人员参考。
