摘　　要：由于目前农村TT、TN两种供电系统并存,河南省社会主义新农村住宅示范图电气设计,总结出一张图纸两种供电系统兼用的表示方法。两种系统接地之别在户外电度表箱处区别处理,出线后则完全相同,均设两级剩余电流保护装置、实施总等电位联结。电气、防雷,户内绝缘隔离、户外联合分户一点接地,既等电位又避免户与户间故障电压相互传递。Because of the co-existence of TT and TN power supply systems in the rural areas, the electric design of demonstrating residence drawing of new socialist countryside in Henan Province has tentatively probed a drawing mutually used for the above two power supply systems. The difference of the ground connection of two power supply systems is differentiated at the outdoor kilowatt-hour meter box, therefore the two power supply systems are exactly same after outgoing the lines; the two-stage surplus current protective device is set up and the total equipotential joint is implemented. Such measures as electricity, lightning protection, indoors insulation, outdoors joint with one-point ground connection can successfully achieve isopotential and avoid the transference of the breakdown voltage.
