In the modern city floors, it is necessary to establish a special distribution grounding system, so as to better ensure the safety of buildings and electricity. At the same time, with people's higher and higher functionality to the buildings themselves, many buildings at this stage are constantly meeting people's new requirements, which makes there are a lot of equipment in the buildings;Among them, electrical equipment is one of the most basic types, and a special grounding and electrical protection measure for power supply and distribution is set up when electrical equipment is regulated, so that the equipment can run stably. In essence, power supply and distribution grounding design and electrical protection have now become the foundation of building construction, and how to design power supply and distribution grounding in buildings to better protect electrical equipment needs to develop more new design schemes in actual construction. Based on this, this paper takes the grounding design and electrical protection of power supply and distribution in buildings as the breakthrough point, and expounds several grounding design schemes of power supply and distribution that are often used in buildings, hoping to bring some help to the actual electrical protection.展开更多

The renovation design and construction of the temporary hospital is very short, so major changes to the original building should be avoided. This paper takes the reconstruction of temporary hospitals as an example, and summarizes and analyzes the design points, key points and difficulties of power supply, distribution, lighting and fire fighting for the reference of designers of similar projects.展开更多
