经济发展和城市建设节奏加快,使得确保施工现场用电安全形势日益凸显.在众多的安全措施中,该文从漏电保护的原理、应用范围等方面对漏电保护器在施工现场的应用进行的了综合比对阐述,认为较TN-C-S与TN-S,漏电保护器(RCD)具有明显优势,应该在实际工程应用领域推广.此外,还给出了漏电保护器(RCD)应用范围和有关注意事项,同时指出电气设备和人身安全保护的措施及与之相配合的等电位联结,这里给出建议和思路有一定的工程应用价值.%The economic development and the acceleration of urban construction pace make the construction site electricity security situation to become increasingly prominent. The principles of leakage current protection and its application scope are elaborated and compared with other safety measures such as TN-S or TN-CS. The comparison result shows that the leakage current protecter has obvious advantages, and should be promoted to the practical engineering applications. The application scope of leakage current protecter and related matters need attention are given. The electrical equipment and personal security protection measures compatible with the equipotential link are proposed. The suggestions and ideas mentioned in the paper have a certain engineering application value.
