-Prepare construction process documents and quality control plans.

2. Material preparation

- According to the design requirements, purchase high-quality PDC body materials, electrical components (such as circuit breakers, contactors, relays, etc.), bus bars, wires and cables, wiring terminals, etc.

- Quality inspection of purchased materials to ensure that they comply with relevant standards and design requirements.

3. Prepare tools and devices

- Prepare the tools needed to make the PDC, such as welding machine, cutting machine, drilling machine, wrench, screwdriver, etc.

- Debug the testing equipment, such as insulation resistance tester, voltage resistance tester, ground resistance tester, etc.

4. Preparation of construction site

- Clean up the construction site to ensure that the site is clean, dry and well ventilated.

- Rationally arrange the storage area of construction equipment and materials.

Third, the construction process

(1) Cabinet production

1. Cut the material

- According to the design drawing, use the cutting machine to cut the cabinet board to the required size.

- Deburring and chamfering the cut sheet.

2. Bend

- Use the bending machine to bend the plate according to the design requirements to form the frame structure of the cabinet.

- Make sure the bending Angle and size are correct.

Step 3: Welding

- Weld the joints of the cabinet frame, and the welding quality shall meet the relevant standards.

- After welding, the weld is polished to ensure smooth surface.

4. Surface treatment

- The cabinet body is degreased, pickling, phosphating and other surface treatment to enhance the adhesion of the coating.

- Use electrostatic spraying or spray painting for anti-corrosion treatment, the coating should be uniform, smooth, no flow.

(2) Installation of electrical components

1. Install the bottom plate

- Install electrical components inside the cabinet to ensure that the bottom plate is smooth and firm.

2. Install the circuit breaker

- According to the design requirements, the circuit breaker is installed on the bottom plate and fixed with bolts to ensure the installation position is accurate.

3. Install contactors, relays and other components

- Install contactors, relays and other electrical components in sequence according to the design layout, paying attention to the spacing and arrangement sequence between components.

4. Connect cables

- Use wires and cables that meet specifications to connect electrical components, and the wiring should be firm, neat and beautiful.

- Crimp or weld the connectors of the wires to ensure good contact.

(3) Bus manufacturing and installation

1. Busbar cutting

- According to the design size, use the bus processing machine to cut the bus material to the required length.

2. The bus bar is bent

- Bend the bus according to the design requirements, and the bending radius should meet the relevant standards.

3. Drill a hole for the bus bar

- Drill holes in the bus bar for installing the connection bolts.

4. Install the bus bar

- Install the busbar on the busbar support inside the cabinet, and fix it with bolts to ensure that the busbar is firmly connected and in good contact.

(4) Secondary wiring

Step 1: Wiring

- According to the design drawings, the wiring of the secondary control line should follow the principle of horizontal, horizontal and vertical, to avoid crossing and winding.

2. Wiring

- Connect the secondary control wire to the wiring terminal of the electrical component, the wiring should be firm, accurate, and clearly marked.

(5) Debugging and inspection

1. Check appearance

- Check the appearance of the PDC, including the cabinet structure, coating quality, electrical component installation position, etc., to meet the design requirements and related standards.

2. Electrical performance test

- Use an insulation resistance tester to measure the insulation resistance of the PDC. The insulation resistance should not be lower than the specified value.

- Perform voltage test to verify the insulation strength of the power distribution cabinet.

- Perform action tests on electrical components to check whether they work properly.

3. Test the grounding resistance

- Measure the grounding resistance of the PDC and ensure that the grounding requirements are met.

4. Quality control measures

1. Establish a quality management system, clarify quality objectives and quality responsibilities.

2. Strengthen the quality inspection of raw materials and components, and strictly implement the incoming inspection system.

3. Conduct side supervision and inspection of key processes and important links in the construction process to ensure that the construction quality meets the requirements.

4. Make construction records and quality inspection records, so that the quality can be traced.

5. Security measures

1. Establish a safety management system and implement the safety production responsibility system.

2. Construction personnel must wear safety helmets, safety belts and other personal protective equipment.

3. Regular inspection and maintenance of construction equipment and tools to ensure their safety performance.

4. Set up obvious safety warning signs at the construction site to strengthen the safety management of the construction site.

6. Environmental protection measures

1. Collect the waste and garbage generated in the construction process and clean it up regularly.

2. Arrange the construction time reasonably to reduce the impact of construction noise on the surrounding environment.

3. Take effective dust prevention measures to reduce the emission of construction dust.

Vii. Construction schedule

According to the overall progress requirements of the project, formulate a detailed progress plan for the construction of the distribution cabinet, clarify the start time and completion time of each process, and ensure that the construction progress is completed on time.
