Classification of construction paper?

Commonly used drawings include architectural engineering drawings and mechanical engineering drawings. The drawings used in construction engineering are construction engineering drawings. It can be divided into architectural drawings, structural drawings, water supply and drainage drawings, heating and ventilation drawings, electrical drawings, process flow diagrams, etc. Electrical equipment installation project is an organic part of building engineering, which has different design contents according to different functions of the building. The classification of electrical engineering drawings is usually divided into two parts: internal engineering drawings and external engineering drawings. The following is a classified introduction of architectural drawings brought by Zhong Da Consulting for your reference.

In the installation and construction of electrical equipment, its contents can be divided into plan, system diagram, detailed diagram, secondary wiring diagram and so on. The main types are described below.

1, plan view.

The plan is the basis for installing electrical appliances and laying branch pipelines. It shows the trend of electrical equipment and connecting lines. Its contents include: the plane layout and axis distribution of the building; Names, models and plane positions of various power transformation and distribution equipment; The starting point, laying mode, specifications and building trend of various distribution lines. According to the situation of power load, its planning can be divided into lighting planning, power planning, power distribution planning and so on.

2. System diagram.

System diagram is the most important part of electrical construction drawing. It represents the distribution relationship or scheme of the whole power system, and is usually represented by a single line. From the system diagram, we can see the installation capacity, distribution mode and control relationship at all levels. Laying methods, models and specifications of trunk lines; Load capacitance and wire specifications, etc.
