摘要
介绍了医院接地系统类型的选择,并阐述了TN-S、TT、IT系统在医疗建筑中的具体实现方式。由于医院电气设计中不允许采用TN-C系统,根据医院建筑内部房间功能的不同,可采用TN-S或IT接地系统;对于电击危险性大的手术室,还应采用局部等电位联结等措施。
The selection of grounding system type in hospital was introduced, the concrete realization mode of TN-S, TT, IT system in hospital were expounded. The TN-C system shouldn＇ t be allowed to be used in the hospital electric design, and according to the different function of the rooms in hospital, the TN-S or IT grounding system should be adopted. To operating room with high electric shock risk, the partial equipotential bounding measures should be adopted.
