When looking at the hydropower construction drawing, we must compare the plan with the system drawing, so that we can know where the pipelines of many lines turn and change diameter. When you look at the construction drawing, you must have a strong three-dimensional sense. You must think it's easy for you to get started standing in this room and following many water and electricity pipelines. In addition, the hydropower diagram should also be combined with civil engineering to see whether the structure size and embedded casing size are reasonable, and also know the data such as insulation layer thickness and wall thickness, so as to carry out the construction accurately.
Of course, if you want to learn to read drawings, you need to know the standards of some countries, the basic knowledge of electricians and the knowledge of water pipe construction, as well as the specifications of materials. When looking at the picture, we must first look at the scale in the picture, especially the waterway construction drawing, and we must clearly know where to give it to whom and where to drain it. Where is the installation location of the distribution box and whether the switch size is reasonable.
In fact, it is best to go to the construction site for practical training or simple training. I believe that following the master's careful study, the ordinary lighting, strong electricity and weak electricity in the hydropower map will be well understood.
