With the development of society, the demand for electricity is constantly increasing in both people's lives and the work of enterprises. In order to meet the requirements of our work and life, we often add a large number of transmission and distribution equipment to coordinate the transmission of electrical energy. Below is a brief introduction to the preparation situation before the construction of Low voltage complete distribution cabinet, for your reference.

Before construction, designers should analyze the construction project, query past construction data, investigate the construction site, and develop a reasonable installation and construction design based on relevant design requirements. The equipment and required materials used in the design should be reflected in detail. After the design is completed, it should be submitted to relevant departments for review to further improve the design. After the design review is approved, construction personnel should make choices based on the design. When selecting construction personnel, the design should be explained in detail to ensure the quality selection of equipment and materials.

1. Installation stage of transformer

(1) Transport transformers, design and analyze their installation locations, summarize a series of construction technical measures, use lifting and transportation machinery to install transformers, and ensure that the traction speed does not exceed 0.25 kilometers per kilometer per hour;

(2) Check the transformer, including whether it is installed correctly, whether it is damaged, and whether the relevant parameters are set correctly. At the same time, the installation site should be kept clean to provide a good installation environment for the installation of transformers;

(3) The installation of the transformer can only be achieved after the above inspection process is completed, and it must be ensured that it is consistent with the design drawings, with an error not exceeding ± 20mm.

2. Installation stage of enclosed plug-in busbar

When installing a closed connection busbar, the key process is to inspect the equipment components, including setting the quantity and specifications of each component, to ensure that they meet the design requirements. Once the quality of the parts is found to be unqualified, they should be replaced immediately to avoid potential safety hazards for future equipment use. At the same time, hangers should be made and installed according to different types of projects, hangers with different structures should be designed, and drilling holes should be set on the hangers. The drilling diameter shall not exceed 1.5 times the diameter of the fixed bolt. At the corner of the enclosed connection busbar, it must also be fixed to the equipment connection, while ensuring that the distance between the hanger and the straight section of the connection busbar does not exceed 1.7 meters. In addition, to ensure the safety performance of Mining distribution box, it is necessary to install a certain grounding wire.

3. During the installation phase

During installation, the installation should be carried out according to the designed equipment installation design drawings, and a comprehensive inspection of the Control box and distribution box should be conducted to ensure that the equipment is intact and the accessories are complete. Corresponding records should be made and some accessories should be saved. Some require secondary transportation
