ABSTRACT

With the rapid development of social economy and the continuous improvement of science and technology, the demand for electric energy is increasing, and people are increasingly dependent on electric energy. The requirements for personal safety, equipment safety and power grid safety of power grid employees are getting higher and higher during their work, so it is necessary to eliminate obvious and potential potential safety hazards during the installation of equipment. In this paper, the problem that the installation of the grounding rod at the lower door of the switch cabinet is not secure and difficult to install is studied in depth, and a new type of multi-functional direct plug-in grounding rod is designed. This design effectively solves the problem that the installation of the ground wire is not secure and difficult to install, and ensures the safety of the staff, equipment and electric network.
