接地,作为医用高压氧舱这一载人设备的必备设施,得到十分广泛的应用。接地检验方法正确与否成为影响医用高压氧舱检验质量的敏感因素,通过案例讨论,提出检验的有效方法。1 问题的提出以下是笔者在检验中总结的几起典型案例:1)海城市某医院使用的5台单人氧气加压舱氧舱,舱体接地全部采用导线连接上水管路。检验结论为无接地设施,重新施工安装接地装置;2)某大型医院2003年11月投用的一舱双室中型舱,在安装监督检验中发现施工单位将舱体接地接入房屋避雷网中。检验结论为重新施工安装接地装置:3)某医院2004年购置中型舱在定期检验中发现保护接地和舱体接地并联,采用同一接地体。检验结论为重新施工安装接地装置;
Ground, as a medical hyperbaric chamber manned equipment necessary equipment, has been very widely used. Grounding test method is correct or not become the impact of medical hyperbaric chamber test quality sensitive factors, through case discussion, put forward an effective test method. 1 The question is raised The following are some typical cases that the author summarizes in the inspection: 1) 5 single-oxygen oxygen tanks used in a hospital in Haicheng City, all of which are connected to the upper water pipeline by wires. 2) A large-size hospital in November 2003 put into use a two-compartment cabin medium-sized cabin, supervision and inspection of the installation found in the construction unit will be connected to the cabin body grounding lightning network . Inspection Conclusion Re-construction of the installation of grounding devices: 3) a hospital in 2004 to purchase medium-sized tank in the periodic inspection found that the protective earth and the tank ground in parallel, using the same grounding. Test conclusion for the re-construction of the installation of grounding devices;
