How to understand hydropower construction drawings? Detailed explanation of the symbols of the hydropower diagram, clear and clear

1. a: Number of lights b: Model or number c: Number of bulbs per lighting fixture d: Bulb capacity, Unit We: Bulb installation height, Unit mf: Installation method L: Type of light source, such as incandescent lamp or fluorescent lamp Through the above detailed explanation of common symbols in hydropower drawings, I believe you can already have a preliminary understanding of hydropower construction drawings. In actual construction, it is also necessary to combine system drawings, construction operation instructions and other documents to comprehensively consider various factors to ensure construction quality and safety.

2. Other installation method codes and detailed explanations are omitted.) By understanding these symbols, you will be able to interpret hydropower construction drawings more effectively and ensure the accuracy of construction operations. For specific logos such as CC and FC, they represent covertly applied in the roof and covertly applied to the ground, respectively. The complete symbol meaning and usage scenarios can be found in relevant materials.

3. The reading points of hydropower installation drawings confirm the overall layout of the drawings (such as 1:100) and the direction signs (usually up to north and down to south), and clarify the functional division of each area (such as toilet, kitchen, etc.). Observe whether the route direction complies with the specifications: the ground pipe must be horizontal and vertical, the distance between strong electricity and strong electricity is ≥5cm, and the distance between strong electricity and weak electricity is ≥ 15cm, and try to avoid crossing; avoid routing pipes on the toilet and kitchen floor, and try not to run pipes horizontally on the kitchen wall.

4. YJV: Cable SYV: TV cable PE: Ground PEN: Zero connection KV: kV BV: Scattered wire MEB: Total equipotential LEB: Local equipotential WL: On the water construction drawing, it is a sewage riser, on the electric construction drawing. On the basis of understanding these symbols, it is also necessary to comprehensively study the drawings in conjunction with the system drawings, construction operation instructions, etc. Through continuous practice and experience accumulation, we can gradually improve our ability to understand hydropower construction drawings.

5. How to view the water construction drawing (water supply and drainage construction drawing) ① See the general instructions: We can see the model and material of the embedded casing from the drawings. For example, panels and sinks should use flexible waterproof casings, and other places should use ordinary casings or hard waterproof casings.② Look at the system diagram: You can understand the installation standards and diameter of the casing through the drawings.

What does the pc symbol mean in electrical drawings

1. In the domestic common industrial and civil electrical distribution drawings, PC is the abbreviation of Power Center, which refers to a low-voltage distribution cabinet that centrally distributes power circuits. It is generally matched with numbers or alphabetical numbers to distinguish different equipment, such as PC-PC-AL, etc., such symbols usually appear in low-voltage distribution system drawings and main wiring diagrams, and are used to mark the core equipment of power distribution.

2. In hydropower engineering drawings, letter symbols represent different materials, equipment or installation methods, and the specific meanings are as follows: SC: Steel pipe, used for pipeline laying. PC: PVC polyethylene flame retardant plastic pipe, used for cable tray laying. CT: Bridge refers to the type of cable bridge. WC: Concealed laying along the wall means that the cable is laid along the wall in a dark place. WS: Open laying along the wall means that cables are laid in open places along the wall.

3. PC: Represents PVC polyethylene flame retardant plastic pipes. CT: Represents bridge. WC: means laying concealed along the wall. WS: means that the orange shape is laid openly along the wall. CC: indicates that it is laid covertly along the roof. F: It means that it is secretly applied in the floor. CE: means that it is applied openly along the top plate. YJV: Represents cable. SYV: stands for TV line. 1 PE: Represents grounding (both yellow and green phases).

What do the various code names in the hydropower diagram mean?

J stands for water supply pipe;W stands for unit watts of power of sewage pipe or drainage pump;F stands for waste pipe;pc stands for hard plastic pipe;ct stands for cable bridge;cp stands for metal hose;SR stands for steel wire trough;RC stands for water gas pipe;CT stands for cable bridge laying;SR stands for laying along steel cables;CLE stands for laying along columns or spans columns;WE stands for laying along walls;CC stands for laying along cast-in-place slabs.

TV stands for cable TV terminal socket. TP stands for telephone outlet. TO means communications outlet, and its full English name is Telecommunications Outlet. For example, telecommunications refers to telecommunications or telecommunications. In future TV screens, they will be connected to an emerging global telecommunications network, the World Telecommunications Grid.

In hydropower engineering drawings, letter symbols represent different materials, equipment or installation methods, with the specific meanings as follows: SC: Steel pipe, used for pipeline laying. PC: PVC polyethylene flame retardant plastic pipe, used for cable tray laying. CT: Bridge refers to the type of cable bridge. WC: Concealed laying along the wall means that the cable is laid along the wall in a dark place. WS: Open laying along the wall means that cables are laid in open places along the wall.

In hydropower engineering drawings, letter symbols represent different materials, equipment or installation methods. The following is an explanation of some common symbols: SC: Steel pipe, used for pipeline laying. PC: PVC polyethylene flame retardant plastic pipe, commonly used for wire laying. CT: Bridge, used for laying and supporting cables. WC: Concealed laying along the wall means that the wire pipes are laid hidden in the wall.

What pipes does the building water and electricity icon pc represent? Are any netizens clear?

1. In building hydropower icons, PC usually stands for polyvinyl Chloride pipes.

2. e-Laying method and pipe diameter, d-conductor cross-section, c-number of conductors, b-conductor model.

3. The responsibilities of building hydropower installation and construction workers are also very important. To ensure smooth water and electricity, regularly repair hydropower pipelines, formulate emergency plans for sudden accidents in hydropower pipelines, promptly repair and eliminate sudden accidents or failures of hydropower equipment, and record the work.

4. Standardization and versatility: Standardization of hydropower icons is the key to ensuring barrier-free communication between different engineers and workers. These symbols have unified standards around the world to ensure correct implementation of projects and effective communication.

5. SCE: Laying in suspended ceiling, metal pipe shall be worn. B. What is the meaning of 2PCwc .fc .cc and other three groups of letter codes in hydropower building drawings PC refers to engineering plastic pipes.
