Abstract： Specific project case is used to discuss the loose and unreasonable connection between design intent and construction technology during construction on site from the perspective of resident electrical designer,including the connection of feeder line of low‑voltage cabinet,installation of residual current transformer,grounding of copper sheath of mineral‑insulated cable,drainage at the substation,setting of feeder circuit of AC cabinet,installation of electric box,and installation of cable transfer box of closed‑type busway,etc.

Key words：resident electrical designer;construction technology;connection of feeder line;installation of transformer;grounding of cable copper sheath;BA control;gas fire extinguishing;control and signal feedback connection

摘　要：结合具体工程案例，从驻场电气设计师视角阐述现场施工中遇到的设计意图与施工工艺之间衔接不紧密、不合理的情况，包括低压柜馈出线接驳、剩余电流互感器安装、矿物绝缘电缆铜护套接地、变电所排水、交流屏配出回路设置、电箱安装、封闭式母线槽电缆转接箱安装等。
